VP5 – Turks & Caicos Islands #143 on 6 m

After the VHF contest was finished this afternoon I still monitored 6 m for another while while starting to disassemble all the equipment. There was another multihop ES opening into North America extending as far south-west as W5 with EM50, EM51, EM52 to be seen in FT8. Unfortunately I couldn’t raise anyone, just transceiver output power was obviously not enough as well as probably too many callers, too. Also in & out on FT8 was VQ5Z from Providenciales Island, Turks & Caicos Islands. Pete, VE3IKV, is expeditioning the Caribbean again, something he likes to do almost every summer with a special focus on 6 m to hand out new ones. While I couldn’t catch him on FT8 he later switched to CW (which is far more efficient if you have a decent opening! good decision, Pete) and was an easy QSO there! Maybe because all of the 6 m DXers & square collectors only hanging around in/on FT8 nowadays? 😎 Of course FL31 was a new square (#662), too. 😉

DARC July VHF Contest ’18

Well, I’m not sure what to think of this one. Equipment played very well. I didn’t sleep more than 2 hours so plenty of BIC time (“butt in chair”), too. Conditions were quite okay also but still only a bit over 340 QSOs/140k points in the log – rather disappointing! 🙁

I missed about 20-25 QSOs from JO30/31 and another 30+ QSOs from OK. There were no holidays yet in North Rhine-Westphalia (i.e. JO30/31) and as Germany was knocked out of the FIFA World Cup quite early it probably wasn’t due to people watching football all weekend long either. On the other hand we had quite good weather down there but even then people normally return to the radio during the evening or early Sunday morning to hand out a few points but not so this time. Strange!

There was some slight tropo condition enhancement during the contest, too. While it was not that pronounced overhere, i.e. I “only” worked a few more east coast Gs than usual, there was a good path from LA to western and southern DL as well as from the U.K. to OK/OM and southwestern DL. Some Gs even worked down into Hungary over 1.400 km during the night! But still activity was lacking quite a lot, really a pity! 🙁

But lets wait and see what the result is good for! Tom, DG3FK/DR1H was on again from JN59OP and should have done over 700 QSOs so probably the clear winner again. With some luck my result should still be good enough for a TOP3 finish … we’ll see. 😉

Good 4 m ES and a bit of 6 m DX, too

Arrived at the station early afternoon today. Unpacked the IC-7300 to set up with the transverter for the 2 m contest this weekend when seeing 70 MHz was open! Had a great time working the band. Especially enjoy the openings into the U.K. as activity is quite high over there … 4 m has been a regular band in the U.K. for decades already! Lucky to get a call from IO93 providing square #171. 😎

Also switched “down” to 50 MHz a few times as I saw on the DX cluster there was some triple and quadruple hops Sporadic-E across the pond, too. Being QRP on 6 m I could only raise two souls but K7BV in North Carolina/FM04 provided a new one on 6 m, too, now #661. 😎

Small tropo opening into the U.K. tonight

Tonight was the usual first Tuesday every month 2 m NAC (Nordic Activity Contest) which is accompanied by the UKAC (UK Activity Contest) as well as the IAC (Italian Activity Contest) as well as the SPAC (SP = Polish Activity Contest). That means the band usually sees quite a high activity level during these 4 hours events. While I was QRV in the NACs (which also have an Open Class for non-Scandinavian participants) regularly in my younger years I now try to hand out a few points at least whenever possible (which is unfortunately not that often nowadays). Did so this evening again but started falling asleep right in the middle. 😉

Whenever waking up and quickly tuning the band I recognized there was some tropo condx between western Scandinavia and the United Kingdom. Also a few Germans like Tor, DJ8MS, located about 200 km west of here, could works lots of Gs but unfortunately nothing overhere. It was just after the end of the NAC that conditions picked up that much that some ducting started to reach over here, too! Luckily the UKAC only ends 30 minutes after the NAC thus there was still some activity on the band and I could grab a few nice DX contacts! 😎

A transverter interface for the ‘7300

After the quite good experience with the Icom IC-7300 during WPX-CW I thought it might be a nice idea to also try it out with a transverter on 2 m in the big VHF contest in two weeks. When searching around for information about the ‘7300 a few weeks (or was it month’?) ago I came across a few websites that described solutions how to interface transverters to the transceiver. The most intriguing one was the one by DB6NT (yes, he of Microwave transverter fame): Michael developed a small PCB that could be built into the transceiver instead of the external tuner interface providing low power output (around 0,3 mW) as well as receive input. It consists of only a few parts and is well designed, i.e. when you apply 12 V power to it small relays switch TX & RX to Cinch sockets while without power it all goes the normal way, i.e. taking the PA stages, etc.

A really clever design! And inexpensive, too! So I bought a kit at his booth during the HAMRADIO fair in Friedrichshafen early June and now finally got around to assemble it and build it into the IC-7300. The trickiest part certainly was soldering the small 0805 SMD parts to the PCB but with only a few of them widely spaced everybody should be able to do it. Unfortunately I didn’t take photos of inside the transceiver but Michael has a great step-by-step tutorial on his website which shows the innards, too, if you’re interested. I also built a dedicated set of cables for the combination, i.e. BNC-to-Cinch for the RF lines as well as 12 V to power the transverter board plus PTT out from the 7300’s 13 pin ACC socket. For a more permanent setup it would of course be more comfortable to have a way of switching the board’s power on & off, i.e. by a switch or the like …

Setting it all up and seeing how big the transverter (an HA1YA one) is compared to the transceiver (or the other way round: how small the ‘7300 is compared to the transverter) I was fascinated again how much technology and functionality you can squeeze into such a small box nowadays. 😎 The only “drawback” of the combination is the ‘7300 does not support a transverter frequency display, i.e. you can’t set the display to show the end frequency like 144.300 MHz but will only see the IF frequency (28.300 MHz in this case). But that is really nitpicking taking the transceiver’s price into account. 😉 What you can also see if you take a closer look at the spectrum display shown on the front photo is that my SPS is switching at around 38 Hz. 😉 Band noise will probably cover it well enough else I can still switch over to a linear power supply. I tested it already and with that one the spectrum is perfectly clean, I was just too lazy to take a new photo. 😉

Now I’m eager to see how the combination will perform during the contest! Will keep you posted, of course. 😉

PJ4 – Bonaire #142 on 6 m

Returning from QRL today 6 m was closed. I left the RX on 50.313 MHz FT8 in monitoring mode while doing different things around the shack. Every now and then some signals from EI popped up and vanished again. Then suddenly the band opened into the Caribbean – 4 hop ES! Signals were in & out but eventually Peter, PJ4NX, popped up for a few minutes and I had the chance to grab him for a new one on 6 m. 😎 That contact also brought back nice memories of our trip to Bonaire last November where we met Peter a few times. 🙂 Besides Bonaire I could also work WP4G from Puerto Rico …

It was also good to catch the ESØUG guys on their way back home staying in KO17 for one night before taking the ferry back to Germany. Distance was now only 730 km so it took quite a while to work them on Meteor Scatter on both 6 m (YL/DL3BQA) & 4 m (YL/DGØLFF), reflections were sparse only, too. But it was a new square on 4 m so well worth the effort. This time it also worked on 2 m (YL/DH5FS) although the contact took almost half an hour on FT8 and I believe it was rather MS enhanced than troposcatter. But in the end it doesn’t matter as long as the QSO is in the log. 😉

Weekend VHF activities

Unfortunately not that much to report. I had blocked the weekend for the IARU Region 1 50 MHz contest but conditions were basically non-existent. A few Meteor Scatter contacts every now and then, nothing else worth mentioning on Saturday. 🙁 On the positive side it was easy to catch the ESØUG guys via Meteor Scatter now from KO19 on 6 & 4 m for a new one. 😎 Despite showing a 6 m frequency the screenshot right was from our 4 m QSO, I had just switched back to 6 m FT8 for monitoring already when taking the screenshot. 😉

What I had totally forgotten about was that the AGCW-DL VHF contest was on Saturday afternoon, too. So I did only spent the second half in the contest (really need to put a marker on the calendar …). This is a fine small 3 hours CW-only VHF (and another hour UHF) contest 4 times a year in which besides the “normal” exchange (i.e. RST, serial number & locator) also the power category is sent, i.e. A = max. 5 watts, B = max. 50 watts and C = more than 50 watts. So you get quite a good feeling what’s needed to bridge certain distances. It’s always astounding to see what works with small power using CW, my two most distant QSOs were with low power stations! These were the TOP 10 contacts by distance:

Sunday was still rather bad conditions-wise, 50 MHz only really opened for the last hour of the contest into the Mediterranean with only sparse activity but great signals. Nevertheless with a good 15 minutes or so opening Sunday morning via double-hop ES to the Arabian Peninsula we had a highlight, too! It’s rare that we are in the middle of the propagation focus to hear such strong DX signals up here:

9K2HN on 6 m Sunday morning:

In general I find that this year’s Sporadic-E season is rather bad so far. Maybe I still have too good memories of last year when May & June were really brilliant! On the other handside July was a catastrophy with almost no openings at all so maybe it’s just the other way round this year? Hope is the last to die. 😉

ESØUG & ESØUG/8 – IOTA & VHF DXpedition

Uwe, DL3BQA, co-owner of our station, is currently on an IOTA & VHF DXpedition to Estonia. He was joined by some guys from Dresden (DM7A contest club), i.e. Fred, DH5FS, Steffen, DH1DM, and Henrik, DGØLFF. You can see their schedule on the lefthand picture and their expedition blog at https://baltic2018.blogspot.com which also hosts a few more operating information.

I worked the guys yesterday evening on 6 m via Meteor Scatter and also heard/saw them for a short while on 2 m Tropo on FT8 but unfortunately no complete QSO although distance should not be that much of a problem at only 822 km. Maybe better luck next time and certainly not that important, I do have KO18 worked/confirmed on 2 m already. 4 m didn’t work yesterday, simply no “stones” around. Therefor stood up early this morning and caught them on 4 m MS for a new square around 5z before leaving for QRL. 😎

They will close down the station in KO18XD tomorrow morning and move on to KO19. Eager to work them from there, too, should be a new square on two bands at least …

New ones on 6 & 4 m today

Not much to report from the rest of the week. Had another small 4 m opening Tuesday evening but just two QSOs worked. Today was plenty of ES again on 6 & 4 m but most of it was more to the southwest. I was listening to the CS5BAM/B & CS5BFM/B beacons on 4 m for over 3 hours but despite four EA1’s worked on FT8 no other QSOs on Four, pity …

EC4KW provided a new one (#657) on 6 m with IM79, finally. Now only IM89 is missing as the last square in Spain. 😎 It’s been a challenge with these two squares as there is (or was?) still a band 1 TV station down there with protected areas where people are not allowed to transmit at all and beyond that with QRP only for quite some kilometers. So activity from there is quite sparse …

Another new one (#166) was worked with JO81 on 4 m tropo. SP3RNZ/p was visiting a Polish club meeting in JO81RX and took his 4 m gear with him to provide several guys a new one. Many thanks for all your efforts, Greg!

WPX-CW Claimed Scores :-)

Well, seems I was a lucky guy with #2 world-wide and hope the log check will not drop me behind LZ1NG. 😉 Guiseppe, IT9VDQ, clearly had the location advantage again (and is a great OP, of course) but beating LZ1NG who’s a big one on 10 m regularly, too, and has a big location advantage as well, makes me kind of proud … So all the efforts paid off. 😎

Sporadic-E & Tropo on one day! :-)

Wow … that’s been a great evening on VHF again! 6, 4 & 2 m were hot all day long but unfortunately I had to spend the day in QRL. There were some massive 2 m ES openings but I was too close to the clouds anyway so not too disappointed not being able to join the show. Nevertheless I tried to follow what’s going on closely, no problem nowadays with several smartphone apps, mobile browsing, etc.

Finally came home around 8 pm local time and had a chance to switch on the radio. Sporadic-E was still strong but I was still too close to the several E-cloud clusters even on 4 m. But the band opened every now and then albeit spotty but nevertheless enabled me to work a few nice QSOs and with IN79 (good old friend Dave, G7RAU, moved permanently to Lizard Point), IO65 and JO00 even 3 new squares on 4 m, now #165. 😎

Switched to 2 m later on while still having the antennas pointing to the UK when I heard a weak signal on 144.310 MHz. After optimizing the antenna for the best signal strength I couldn’t believe my ears when Chris, GM4ZJI, sent his callsign! Wow, seems I got into a nice tropo duct to Scotland! There was some tropo across the North Sea during the last few days several times but extending over another 300 km land to my location was really not expected! Maybe I should have checked the F5LEN tropo forcast a little earlier as it showed the path to probably open, although rather weak. All stations worked were close to the sea except G3SMT far inland close to the Welsh border so Peter had to pass all of England, too, before reaching the North Sea. Judging from the picture on his qrz.com site he seems to have a nice hilltop QTH so this probably helped to get into the duct from his side as well. I remembered working him back one and half years ago when he was the only one making it into the duct (to overhere), too. Seems there’s some magic to his QTH. 😎

OH5Z’s reaction – bravo!

In my recent WPX-CW blog post I had commented on the bad signal of OH5Z. I was pleased to find an email by Timo, OG9X, one of the operators at OH5Z, in my inbox this morning. He allowed me to publish it here, too, which I will gladly do:

Hi Olli
Thanks for the reply. Yes, you can publish my comment.
We take this kind of notes very seriously because we
want to keep our act clean.
----------------------------------------------------------------
I noticed from your blog that we had a very wide signal on 10 on
Saturday morning. I feel very sorry for that. Usually we have a
clean and narrow signal on both cw and ssb.
This time we had a borrowed radio on one of the stations and now
I see that it had some issues on tx. We will check it and repair
what is needed.
Thank you for publishing this information and I apologize the
contesting community on behalf the whole team.
Timo, OG9X

To me this is the behaviour I would expect and that also triggers “hamspirit” in my mind. Most people either not react at all when you tell them about their bad signals or they just push it back to be an RX problem on the other one’s side. But somebody taking it seriously is rare and therefor appreciated the more. Bravo Timo! Hope you get it fixed soon.

If anybody ever sees/hears that my signal is not okay please drop me a note! I always appreciate it. Only with such feedback you can improve things …

Small 4 m opening

Today saw a small 4 m opening. The band was open for almost an hour to Portugal around 14z. I could hear the beacons CS5BFM/B from IM59 and CS5BAM/B from IN51 quite well but unfortunately no stations QRV. 🙁 Also saw two EAs from IN73 weak on FT8 for a few periods but couldn‘t raise them, they were too busy working stations more westwards … Despite no QSOs good to see the band opening again! 😎

Posted in Propagation, Sporadic E, VHF | Comments Off on Small 4 m opening

First Sporadic-E this season :-)

Well, writing two blog posts on the same day must mean something special! Indeed, it does! 😉 We had the first real Sporadic-E opening here up Northeast. 😎 I’ve been hogging the station for over a week now but VHF condx have been very poor so far. Also today started with no conds and I didn’t expect anything to happen anymore when suddenly there was a cluster of ES clouds evolving in the Southwest early evening and MUF rising rapidly.

But first of all I was a happy camper in the afternoon when working EK7DX on a supposedly closed band on 6 m (this is where FT8 really shines). He provided DXCC #141 on Six as well as a new square (#655). 😎

Besides two Meteor Scatter contacts on MSK144 in the morning I also had a remarkable QSO with GM4FVM on 70 MHz around noon. He was a weak but steady signal but there were no signs of ES at all. So we both suspect it was some kind of Tropo (Scatter) as for Iono Scatter the power (at least overhere) was much too low. There was some tropo over the North Sea recently, too (but more from the U.K. to the Faroe Islands), so maybe that helped a bit? Jim has a nice blog, too, well worth reading!

Around 16z the 4 m band opened via Sporadic-E up here. It took a while until the first QSO as the pileups for the few audible stations were immense and JO73 was not perfectly positioned, signals were much stronger further west. IN50, IN92, IN71, IM76 were new squares but what really made my day was working SØ1WS in IL46 via double-hop ES over a 3.600 km path! Another new square (#162) and a new DXCC #37, of course. 😎

SØ1WS on 4 m:

SØ1WS in QSO with DL3BQA – Uwe couldn’t resist doing his first ever 4 m QSO: 😉

Unfortunately a number of stations were only QRV on FT8 during this good opening. I don’t get the sense of doing so when signals are good enough for CW/SSB which provide a better QSO rate for everybody! Is it just the lazyness of people? Or are they overwhelmed by the SSB pileups thus searching their luck in digimodes where they have more control? There must be a reason …

At 16:34z 2 m opened shortly and I could log EA4CZV. Ten minutes later I heard CT1EWD over 2.400 km which is a really difficult distance (normally already too much for a single ES hop) but another DL further west (think it was JO41/51) was stronger and until they had finished signals dropped down into the noise again. Pity!

Over the next half an hour 2 m opened every now and then for a maximum of 1-2 minutes each time only allowing for 4 more QSOs into Spain but with IM88 even providing a new square (#557) on 144 MHz, too. 😎

After 17:30z the MUF started dropping again still allowing a few more contacts on 4 m until propagation to Spain was gone there, too, around 19z. We had another short but strong opening into Malta quarter an hour later, then the MUF dropped below 70 MHz …

9H1TX on 4m:

Afterwards I called it a day and drove back into town … with a big fat smile on my face. 😉

Now two more days left that I can and will spend in the shack. Will there be additional openings? Well, with my bad luck this year they will probably all occur from Thursday to Sunday when I drive down to Friedrichshafen for this year’s HAMRADIO fair and back to Cologne afterwards. 😉

CQ WPX CW 2018 & further 7300 experiences

Another CQ WPX CW is in the books! As usual I decided to do a 10 m single band operation. I just like the band, especially in sunspot minimum it offers a variety of propagation modes most people are not aware of. But that’s the big problem, too: too little activity even if there are good band openings, if they’re not lasting long enough to stir general activity …

Two years ago I was really lucky with ES conditions almost all weekend long doing over 850 QSOs leisurely on the remote and even broke the current German record by coincidence. 😎 Last year was a rather bad year propagation-wise and guess what? This year wasn’t much better either … but let’s look at it chronologically. 😉

Got up early Saturday morning, i.e. before 4z already. Ten was closed so I took a look on 20 m and the band was quite well open to the US West Coast as well as the Pacific, all direct path! Splendid signals from Hawaii which is usually a rather difficult path almost directly over the North Pole from here. But not so this time, loud signals and no “polar flutter” as is often the case, just clear strong signals like these two:

KH6ZM Saturday morning, 4:20z:

KH7B Saturday morning, 4:51z:

Worked two dozen QSOs then went to bed again for another hour. By 6:30z 10 m opened via Sporadic-E into the Mediterranean and the Balkans. Good old friend Guiseppe, IT9VDQ, made it into the log as my first 10 m contact. Seems he had a great time as SOSB10, too, as he reported on the 3830Scores website. Calling CQ brought a call by Tom, HZ1FI, for my first DX contact, too. 😎

An hour later the band was well open into different directions with very strong signals at times but activity was quite low, a real pity. Biggest signal peaking about 60 dB above the noise (not to mix up with 599+60, hi … 60 dB above noise is about 599+10) was still IT9VDQ (the red one in the middle):

Speaking of big signals please take a look at the following two screenshots. The left one shows the really wide signal of OH5Z around 7z while the right one shows the much cleaner signal of OG55W. Both were about equal signal strength, i.e. s9 plus a bit indicated by the red colored carrier lines (this was important to have a clean base for comparison not to draw any wrong or unfair conclusions).

It goes without saying that taking up 2 kHz bandwidth with one (!) single CW signal is way beyond good sportsmanship. 🙁 Most of his “sidebands” were generated from bad keyclicks (which is not that obvious from the picture). EDIT: Meanwhile the OH5Z guys contacted me and apologized, see here. 🙂

At 10:20z SP4Z spotted AH2R, Guam in the Pacific, as being “strong” from almost 12.000 km away from here! And lo and behold, I could really hear him, too! Unfortunately he was too weak for a QSO, i.e. he didn’t hear me, but then it was still quite fascinating and showing again the magic of 10 m (although 6 m is the official “Magic Band”, hi).

AH2R CQing on 10 m:

AH2R, Guam, working Japan:

I’m not sure what kind of propagation it really was. The normal F2 path does not exist with current sun conditions. Maybe it was really a 5 or 6 hop ES which would be supported by the strong signal produced about 400 km eastwards while I just got into it through scatter for the “last few” kilometers. That many hops aligning perfectly “as needed” is nothing to be expected daily but not impossible at all, we’ve even seen that from DL to VK on 6 m in the past! But maybe there’s a kind of E-layer tunneling involved, too, as supposed by some Japanese guys trying to explain the regular 6 m openings between JA and Europe during the summer month’ …

Ten closed down around 12z, not a single signal anymore and even no locals answering my CQs. Handed out a few points on 15 m were the US East Coast was easily reachable by sidescatter propagation beaming to the Caribbean. Then onto 20 m were stations were wall to wall from 14.000 to about 14.120 MHz as can be seen on the righthand screenshot. The wide line around 14.074 MHz is the FT8 digital mode frequency showing how big most signals are. I’m not sure if honorable Joe Taylor, K1JT, really intedend that digital mode for communication when signals are way above s5 up to s9+. After all it’s a weak signal mode, isn’t it? But I might comment on FT8 in a separate post later, I’m trying it out, too, and still making up my mind about it. 😉

Back to the contest: 10 m opened again around 14:45z, this time into the Canaries. It took another 20 minutes until we had a link into South America. 🙂 A number of juicy 3-pointers made it into the log as well as a nice number of new prefix multipliers. 😎 Around 16z propagation shifted a bit northwards to the Caribbean with NP4Z making it into the log as well as YW4D. The band was good for quite a while into the Iberian Peninsula with an occasional call every now and then by a few more South Americans. We also had a good ES opening into the U.K. with some nice strong signals but then again, activity was sorrily much too low. E-Clouds were ionized so strongly between 17:30 and 19:00z I could even work a good number of backscatter contacts to DL, PA, ON, etc. providing more mults. Good old friend Dave, G7RAU, of VHF fame, called in at 18:33z. I liked his clusterspot afterwards a lot! 😎

It shows how well the path westwards (at least the first hop) was open which also enabled QSOs with 8P5A and FM5BH as additional unexpected Caribbean DX contacts. 🙂 The lefthand screenshot shows band activity around 18:20z. It’s not that much about the number of signals but signal strength’ (from blue = weak over yellow to red = very strong). The band closed at 20:30z with both EA1AER and EA5AER coincidentally worked “in a row” (well, actually 10 minutes apart) as the last two stations on Saturday. 😉 My 10 m log counter showed 270 QSOs, not too bad for the first day with such low activity on the band and long phases of no propagation. Did a few more QSOs on the lower bands before I finally called it a day around local midnight.

Switchting on the 20 dB attenuator (center of waterfall) helps every transceiver on 40 m, not just the IC-7300. 😉

Early up Sunday morning again but band still closed. First signs of activity around 6:30z into the Southeast, i.e. UA6 as well as Sicilly again (Good Morning Guiseppe! ). Overall the morning was rather unspectacular, only 50 QSOs until the band closed again at 12z (Déjà vu from Saturday, eh?).

It only opened once more at 16:30z. Probably nobody expected another opening with these poor conditions so activity was extra low, what a shame. 🙁 Worked a few EAs and Fs and then got called by K9RX at 17:35z. Gosh! 😎 Quickly exchanged report and serials (hope he got it all correct, too) and he was gone again. Suspect it was a 3-hop E-skip with a Meteor extension for the last 4th hop down to South Carolina or somewhere in between. At least it sounded very much like an MS burst … and really pumped some adrenalin through my venes. 😀 I was even spotted by the WZ7I East Coast skimmer later on (see screenshot up right) but unfortunately no more NA contacts were made (nobody called and nobody heard). 🙁

The later the evening the better the DX was certainly true for Sunday night. Until local midnight a few more DX stations from PY, LU & CE as well as PZ5XX, YV4ABR, HK3C, HC2GRC and P4/W1XP made it into the log with a few more heard (but worked on Saturday already).

L-t-r: YV4ABR; me (green marker = my frequency) having just worked G4CXQ for the second last QSO; FM5BH & YW4D, both still strong around local midnight before the band finally faded.

PZ5XX just before midnight on 10 m:

YW4D just before midnight on 10 m:

With 358 valid QSOs I finished the contest on 10 m after the last few signals had vanished around midnight, too. I was quite exhausted (listening to white noise for hours *IS* exhausting!) but still had the urge for some adrenalin from high rates so decided to have a go as “fresh meat” on 80 & 40 m until the end of the contest. Doing 230 QSOs in a bit over 1,5 hours was indeed pushing the adrenalin! 😎 So much I couldn’t sleep immediately when I finally went to bed around 3 o’clock local after listening to 20 m ragchews from the U.S., the band was still wide open! Maybe I should have run these last two hours on 20 m … 😉

IC-7300, PA + 6 ele G0KSC OWA Yagi @ 60 feet

So how did I like the IC-7300’s performance? Well, it played quite well! Of course there are things I’m missing compared to the K3, i.e. the dedicated 2nd VFO knob to tune in a multiplier already while transmitting then just switching VFOs to grab it and back to running. I also had the feeling the K3 would do a little better on 80 m than the 7300 (didn’t test 160 m). The latter just “felt” a bit more noisy but then we had terrible thunder crashes all over Europe on Sunday, too (which even made it difficult on 10 m at times to copy weak callers). And there were 2 or 3 situations were selectivity of the K3 with direct adjacent strong signals present would have been the clear winner. But then we’re comparing an 1200 EUR radio vs. a 4000 EUR radio, i.e. apples to oranges, don’t we? 😉

The dedicated hardware buttons for certain functions on the K3 might make it easier in the one or other situation, too, although the touch screen makes up for the little front panel real estate of the 7300 quite well with important functions reachable on a simple screen press, too. After all this is just a matter of taste … I really liked the spectrum display of the 7300, it helped jumping directly onto new signals popping up. The K3 combined with a P3 can do the same but then it’s more hardware, more cabling, more hassle & more space (the reason I sold my P3 … I have to install the station from scratch everytime I want to play radio locally here). And more money, of course (the P3 adds another 800 EUR to the K3)! So I wish Elecraft would come out with a “K4” which has all the P3 functionality included. Really.

So all in all the IC-7300 is great value for the money, absolutely! You have to be careful in a multi-transmitter environment but you have to be with most radios anyway. I had the OVF flashing once on 10 m while Uwe was transmitting on 6 m but soon recognized I had forgotten to switch in the 10 m band pass filter. 😉

Would I sell the K3 and just keep the IC-7300? No, not at all. I like the K3 a lot although it has it’s (very few) downsides, too (like every piece of electronics nowadays anyway). But I’m very well used to it, it has the 2nd RX, great ergonomics, low weight (which was a benefit during my recent Caribbean trip, too), is to a certain extend self-serviceable, a.s.o. Would I buy the IC-7300 again? Yes, definitely. It makes a really good allround radio with some great features and is contest-able, too. And, it has 4 m included. 😎

IC-7300 – the first “overflow” situation ;-)

Well, yesterday I finally had the first situation with the OVF indicator making it onto the display – frontend ADC overflow! I was wondering why I got it on 6 m and first suspected some strong ES opening with TV/broadcast station from Russia but the band was pretty much closed into that direction! Only when switching the scope to a broader range I recognized a really strong signal on the 6 m FT8 frequency, i.e. 50.313 MHz, and guess who it was? Uwe, DL3BQA, from our second shack just across the wall. 😉

He was transmitting on our new 6 m DX beam which is about 60 m away from my 6/4 m duoband yagi I had connected. While the OVF indicator showed up my RX was desensed by about 25-30 dB, i.e. listening to the SV3 beacon it went from an s7 signal down to about s2/3 but that was all, receiption itself was not affected, no noise, no nothing. Of course the desensing is bad enough but other radios would also make lots of strange noise in that situation! So first I was rather impressed in that moment. 😉

BTW: The 7300 offers 3 different spectrum scope ranges per band (segment) so you can even monitor a smaller different range than you’re actually tuned to as long as it is within 1 MHz. Quite handy for monitoring purposes! In the example below I was tuned to a CW beacon in the lower part of the band while watching the spectrum in the digital section …

Would be interesting to see how the K3 would cope with this exact situation, especially with a P3 connected. It would probably generate some more noise (but maybe not as much as the desensing). We’ve had those situations already but than being no more than 50 kHz away from each other so not comparable to the almost 250 kHz spacing we now had. But to be honest I’m just too lazy to unpack the K3 for just that test. 😉 Guess we’ll see when I’m running the remote to monitor the band while Uwe is doing FT8 again … will be happy to report back then. 😉

A bit of 4 m MS this morning

Played around on 4 m Meteor Scatter this morning (stayed overnight at the station). Conditions were quite nice with lots of reflections from my QSO partners but the low ERP on my side still ment QSOs took very long, in the case of OH7TE almost an hour. But patience paid off and both Yussi and me worked a new square each. 😎

All QSOs were done on MSK144 mode from the WSJT-X suite although I prefer using MSHV by LZ2HV as the “frontend” software.

IC-7300 – first impressions

Now having played with the radio for a few days it’s maybe time to give some feedback on my first impressions. Setup was a breeze! Be it all the menu settings, recording voice files for the internal voicekeyer, programming the CW memories or setting up the spectrum display to my liking was all done within a few minutes! Maybe I do have an advantage here as a long time owner of several Icom rigs in the past. So for me it was all very intuitive, good job, Icom!

Unfortunately there were no big ES openings yet so judgement for strong signal handling on 6 & 4 m still has to wait. Sensitivity at least seems excellent as far as I can tell. Worked a few tropo QSOs on 4 m with some “locals” and it “feels” comparable to the very good HA1YA transverter. Also did a few Meteor Scatter contacts this morning without any problems.

I’m not sure about HF performance yet. As Six & Four were not much open I played a lot on HF, too, and worked quite a number of QSOs. I didn’t experience the OVF (overflow) light yet but I do run with attenuation on the low bands anyway (no matter which radio, band noise is moving the meter high so no need for extra gain). The radio sounds excellent on the higher bands, i.e. 12 & 10 m. I’m not yet decided concerning the lower bands. It “felt” a bit noisy/unruly but it might well be the current conditions and lightnings all around Europe. Will need to keep an eye on it and will probably do the WPX-CW next weekend with the radio, too.

The spectrum scope is great value especially when monitoring “dead” bands. You don’t wanna miss that elusive opening, do you? 😉 I find the built-in recorder quite handy, too. I had an 8 GB SD-Card surplus to my needs so it went into the radio. It can now record up to 135 hours of audio! Also the voice memories for the built-in voicekeyer are stored on the SD-Card. You could even fine-tune them on a PC if needed. And did you know that the radio can even do screenshots? Cool stuff! 😎

This one shows an OIRT station from Russia (well, there actually were two small Sporadic-E openings into that direction yesterday early noon) wiping out about 70 kHz of spectrum with it’s wideband FM signal:

And here’s an according audio snippet:

While it sounds a bit distorted and certainly not WFM quality 😉 it is still intelligible. Four hours later there was another short opening bringing up another OIRT station this time with a much broader FM signal wiping out about 150 kHz of spectrum rendering our small “DL band” of 70.150 to 70.180 MHz useless:

The broader the WFM signal the less the intelligibility, of course:

So the IC-7300 has some really nice and handy features I already like a lot. 😎 I also installed the USB driver and had the radio up & running with CAT control and digimodes within minutes! It can’t get any easier …

Z3 – Macedonia, DXCC #36 on 4 m

Sporadic-E still isn’t kicking off on 4 m. 🙁 There are some slight attempts of the MUF to make it over 70 MHz but so far it’s just scratching it. Under these circumstances FT8 really seems to help, at least it provide me with Z35Z, Macedonia, for DXCC #36 on 4m, and with KN11 a new square (#156), too. 😎

Current antennas

The perfect blue sky weather called for taking an up-to-date photo of our antennas today:

Left to right: Tower with a 6 ele GØKSC OWA for 15 m and an 8 ele YU7EF for 6 m at about 14 m height. Next to the house is a small 8 m tower that used to host our 4 x 10 ele EME group for 2 m which is still not built up again thus only a long 2/70 collinear on it right now. Then the big chimney with a 6 ele GØKSC OWA for 10 m and a 10 ele DK7ZB for 2 m at 20 m height. The chimney also holds the dipoles for 80, 40 & 30 m as well as the apex of our 160 m lazy loop. Attached to the small chimney is a small mast holding my 6/5 ele GØKSC Dualband-Yagi for 6 & 4 m as well as a 9 ele GØKSC LFA for 2 m. The last tower on the right is about 12 m in total height holding a 4 ele YU7EF for 20 m and a 2/2 ele DK7ZB Dualband-Yagi for 17 & 12 m which is offset by 90° to the 20 m beam to avoid SWR interference on the dualbander.

So overall quite a bit of aluminium to play with but still small scale in comparison to all the big guns 😉 and definitely not enough to make up for our northeasterly location … 😐
