CQ WWDX RTTY 2020

Uwe, DL3BQA, was going for a serious 80 m effort like last year. Heiko & him had installed our 80 m GP antenna behind the 15 m beam again so a bit of distance to the other antennas giving me a chance to play on all the other bands without too much interference.

Sporadic-E on 10 m Saturday morning …

Nice to see 10 m open a little although still far away from what will be possible again in 3-4 years (hopefully). 😉 Pretty much the same number of QSOs like last year but more multipliers thus a 10% increase in total points. 😎

Tropo seems to be over

Tropo seems to be over. A few QSOs in the morning then no DX signals anymore. Enjoyable five days of VHF DX although mostly FT8 only. But at least contacts could be made. In earlier years it would have been “Oh, there’s tropo between G/GM and JO43/53 but not here” in CW/SSB but in this case FT8 really had an advantage (although I wished I could have worked all these contacts in SSB, too). 😉

Tropo shifting

The high pressure system is moving to the North-East. So just one QSO to Scotland still in the morning and nothing during the day but I also had to concentrate on QRL again. 😉 In the evening it was Scandinavia then but no big distances from here. Still nice to work all the guys in Sweden and Norway and even two times Finland. Also heard ES8AJM/KO18 but he was in & out only and busy working others.

Tropo still

Still pretty stable signals from Northern U.K. today. GI4SNA was pounding in all day long, amazing. Early evening EI2GLB popped up but was in & out only on FT8 but I finally caught him and thus crossing the 1.400 km mark.

But the most enjoyable QSO was made with EI4IR in SSB being even further away! 😎 I always check when I see signals popping up in the SSB portion of the band and wouldn’t believe it when Patrick called CQ on .300 with a rather stable and loud enough signal. He was only running 80 watts which made it even more cool. 😎 A pity I was not set up to record audio from the FLEX setup.

My ODX in this tropo session was then even further extended when catching EI8KN (this time FT8 again) later this evening … 1.441 km isn’t too shabby. 🙂

Tropo continues

Tropo condx continued today. There were some long distance contacts reported to the East in the morning, too, but only UR4WWT heard and worked over here which is pretty much normal tropo range (worked him several times on CW in the July contests before), else it was westwards only again.It all concentrated on the northern part of England plus Scotland, Isle of Man and Northern Ireland. Most of the IO74/75 and IO85/86 guys were in more or less continually while all the others were rather in & out so you had to be quick (there were a number of non-completed contacts, too).

Tropo

Finally with a stable high pressure system across the North Sea and nice autumn weather (one month later we would call it a Golden October, hi) we got a little tropo, too. Not well suited here in JO73, it’s much better 100 km north in JO64 and even better in JO43/53 with quite some SSB contacts made there, too (where I can only hear the German guys but not the DX). So FT8 needs to do the job and it indeed delivers. Completed the following QSOs today:

WPX-CW ’19 World Win Plaque

Nice surprise when getting back home today. The plaque for winning the world on 10 m in WPX-CW last year [1][2][3] (a once in a lifetime event from here) was finally received. 😎 Doug, K1DG, managing the plaque program of the CQ WW WPX Contest, had already sent one in February but it never arrived over here. 🙁 After a few month’ we finally declared it lost and Doug was kind enough to make a new one and send it over. This one now arrived within 3 weeks as expected. Many thanks Doug, appreciate your efforts!

Perseids final

My final day being active in this year’s Perseids. Seems there was a second peak (or THE peak?) of meteor activity this morning. My gut feeling is the shower is still not on par with recent years. There were very few reflections today (better in the morning with a sharp decline around noon) but the ones that were there were all very long, typical for after the maximum.

Did work UA3TCF/LO26 for another new square making it 7 in total. Wow, would not have expected that many! Maybe 2 or 3 but definitely not more than half a dozen. Great. 😎

More new ones thanks to the meteors

Did we see the Perseids maximum already? Predictions suggested it would be early morning 12 August. The screenshot right (click to enlarge) seems to confirm it. If the maximum is over already it has indeed been the worst Perseids I every experienced …

Better luck on the “low bands” (of the VHF ones at least, hi) today. After several attempts I finally finished with LA7QIA/JO29 for a new locator on 4 m. 🙂 Four also opened shortly via Sporadic-E into the Mediterranean. Worked GW8ASA during that time, too, but due to the nature of the QSO, i.e. no constant signal compared to the EA’s,  I think it was rather Meteor Scatter with some good bursts. Also made a short appearance on 6 m to grab SM3LBN/JP62 as a new one. 🙂

A bunch of nice QSOs were made on 2 m, too. UA3LAZ/KO65 provided another new square. 😎 I was wondering why people who had worked UA6LQZ yesterday (as I did, too) were calling him again today. It did not take long to recognize from his CQs that he moved on from LN19 to LN18 so I quickly QSO’d him for another new square, too. Was using the smaller remote setup (Flex-6600, ME2HT-PRO transverter by HA1YA, 800 W SSPA + 9 ele G0KSC LFA-Yagi @12 m) to catch him as I was busy with the main local rig (IC-9700, GS35 + 10 ele DK7ZB Yagi @21 m) in parallel working RU4NG/LO48 for another new square. 😎 RU4NG heard me on MSK144 over 2.250 km while I was beaming 40° off! We switched to FSK441 (which has a gain advantage of about 2-3 dB over MSK144 and also decodes smaller pings up to 200 ms) and started a dedicated sked away from the crowd. Patience was needed, it took 1:15 hours to complete but it was certainly worth it. 😉 Luckily it is common standard to use 30 seconds periods for both, FSK441 and MSK144, on 2 m in Europe else I would not have been able to run two rigs in parallel without QRM’ing myself. 🙂

MS condx slowly improving

Besides playing with the satellites MS conditions improved a bit, too. Still way below usual for Perseids but at least three QSOs above 2.000 km already and three new squares with LO31, LN19 and IM79. 😎

Tried a little on 4 m, too, but except GW6TEO no QSOs completed. Seems my QRP setup (20 watts + 5 ele Yagi) struggles much more on MS than ever before. 🙁

Working the birds …

Started playing with the satellite function of our IC-9700 during the last few days to escape the boredom of too few MS reflections. 😉

I made my first satellite QSOs back in 1992 not much later than getting my first VHF license. Back then it meant the world to me being able to work biiig distances with my small equipment. My favourite sat was the Russian RS-10/11 which was very sensitive so 20 watts into a half-wave vertical on the 2 m uplink produced a loud and clear signal on the 10 m downlink with just a simple wire antenna. Due to it’s height in orbit QSOs could easily be made up to about 4.000 km. 😎 A few portable activities a few years later gave access to AO-13 with it’s “world-wide” foot print and much more DX, too. Was active until about 1997 then starting QRL and being hundreds of kilometers away from home with no own station I was not very active anymore and when I had a chance to operate I rather concentrated on contesting on HF and VHF. 😉

Nowadays there’s quite a number of Amateur Radio LEO (Low Earth Orbiting) Satellites in space that allow communication without too much effort. A few FM-only birds (AO-91, AO-92, PO-101) but also a number of sats with linear transponders (XW-2A, XW-2B, XW-2C, CAS-4A, CAS-4B, RS-44). Unfortunately it seems activity on the linear sats has vanished over the years, too. Most of the time I was the only guy on the transponder, quite a pity. Activity there seems to concentrate on the weekends or evening hours.

DH8BQA, IK1ZOZ/8 & OH5LK on CAS-4A:

The contrary on the FM birds, always much activity and people QRM’ing each other more often than needed. Of course this happens, it’s a single channel only, no different to terestrial repeaters. The linear sats would offer much more space for everybody …

I was using the ‘9700 barefoot with a horizontal 10 ele DK7ZB Yagi on 2 m and just a 6 x 5/8 lambda vertical on 70 cm. Not the best setup as both antennas work best at low elevations due to their vertical patterns and both linear polarized. So I had difficulties at times hearing the birds or accessing them but after all still made about 70 QSOs during the last few days with the most enjoyable probably being W2RDJ/FN32 in SSB with over 6.200 km distance through the good old and still sometimes working AO-7. Other good DX included R9LR/MO27 at 3.200 km and EA8/EA4NF from IL39 at 3.400 km on the FM birds.

R9LR on AO-92:

Unfortunately CN8JQ and OX3AH, which would have been new satellite DXCCs for me, could only be heard …

OX3AH on AO-92 just when ‘loosing’ the satellite here:

More information about Amateur Radio Satellites can be found on the websites of AMSAT, AMSAT-UK, AMSAT-DL and many others (Google’s your friend). Here are a few more sound snippets if all this is new to you. Stereo audio, left channel is satellite RX, right channel local audio.

AO-92/Fox-1D ID’ing itself (whenever it crosses from light into darkness?):

Quite a good pass of AO-91/Fox-1C:

UT5EDU worked on PO-101 (a rather difficult bird):

RS-44 CW ID on 70 cm being 3.500 km away:

Quite a slow start

Not many reflections yet. A few long and strong ones as I produced at RQ3P (see screenshot) but still much less than we’re used to from earlier years. Usually spending most of my time on MS beaming East. Activity by the friends in Russia has been rising constantly during the last few years so chances are much higher to work new stations or even new squares from that direction. And it’s possible to work higher distances i.e. better DX to the East, too. It’s difficult to the West as there’s only water (Atlantic Ocean) “behind” G/EI as seen from here in JO73 wich limits distances to about 1.500 km max. (if there’s no maritime mobile activities, hi). Same to the South, not much to work in the Mediterranean. So only 3 QSOs on MS today:

Perseids have started

It was quite quiet on the blog here during the last few days and weeks. Not much time to play radio but as one of the most intense Meteor Showers of the year is approaching I decided to take a week off QRL and spend the time at the contest QTH. Arrived today, set up the station and did the first MS QSOs already …

DARC July VHF Contest ’20

Oh boy. Seems this is the third year in a row to complain. 😀 Indeed conditions have been even worse than during the last few years. Saturday had such bad condx I could not even hear the big guns from Slovenia which are 700+ kilometers away and usually S5-7 at least. Nothing, nada, zilch, … no copy! 🙁 No Croatia and no Hungary either! Even signals on the shorter path’, i.e. like 250 km, went from S5 or sometimes even S9 down into the noise unreadible within seconds! Was it the bad condx or just bad participation, too? I really struggled to make QSOs on Saturday, no fun!

It only got better late in the evening with condx stabilizing a bit and at least a few of the big ones from Slovenia and Hungary finally popping out of the noise. Still lots of QSB but rising activity from the OK/OM guys on CW helped a bit (although QSO totals with them still way below what we were used to a few years ago). “Luckily” everybody else I talked to complained as well so I was sure it really was the condx, not the equipment. 😀 Interestingly the contacts to the east, i.e. Poland & Lithuania, were much less QSB affected.

Slept about 3 hours. Sunday morning was much better, conditions as well as my mood. Seems they are linearly linked to each other! 😀 Activity was higher now and more DX could be worked, too (although much less than usual). While I still struggled with some of the big distances Croatians the QSO with YT4B over 1.074 km was an easy one and worked right away! 😎 Always amazing, the guys must use a really great location and equipment!

In the end I still made over 350 QSOs, on par with the last two years. But the kilometer average was way down this year thus missing about 10-15k points compared to last and second-last year …

A band-pass filter for 144 MHz

To cure our severe RFI issue described in one of my recent blog posts I decided to order an 144 MHz BPF. Found it on Ebay first but finally ordered from the seller’s Italian web shop directly and saved another 10%. 😉 What sold me on this one is the 3 cell helical design promising excellent attenuation data. It arrived within 4 days, ufb service!

The JG-BPF2M atop of my FA-NWT ready to be swept

Before installing it in the station today I made a few measurements with my FA-NWT network analyzer (an improved version FA-NWT2 is for sale by BOX73 if you ever need one). It does not quite meet the promised -100 dB @ 98 MHz but still is very good. It surpresses all of the amateur radio HF bands by at least 65 dB (at some frequencies even more than 80 dB).

Full sweep from 0 to 200 MHz

Zoomed into the HF spectrum only – at least -65 dB on all amateur bands 😎

Flat passband across the whole 2 m band

The measured insertion loss is still acceptable although it could certainly be further optimized as the filter’s low of 0,2 dB loss is just below the 2 m amateur band

Integration into the station went smooth. Nothing to take care of, it works both ways. 😀 It’s now connected between my trusty HA1YA transverter and the 2 m amplifier. Extensive structured testing confimed that all RFI from high power on the HF bands is gone now. 😎

Rare 2 m ES to the Northeast

Arrived early afternoon at the station today. Wanted to prepare a few things for the VHF contest this weekend and was monitoring the bands, of course. Thus no surprise I caught another short 2 m ES opening, this time to the Northeast which is very rare, ES on 144 MHz usually to the South (plus East/West) only from here. RX1AS was very weak (about a 51 report) calling on 144.300 MHz SSB but unfortunately I could not raise him with just 100 watts (knowing his ‘working conditions’ I don’t wonder why, hi). Until the amp had warmed he was down to 31/41 at best so even with high power no QSO possible, pity. This time no signals on FT8, imagine that! 😀 Seems the opening was much better further west (and with longer distances).

We also had quite an intense opening on 4 m to the Balkans again in the afternoon but just a few QSOs, there are simply not enough stations QRV. But at least LZ3AD was a new callsign in the log. 😎

New squares on 4 m

A few single QSOs during the last few days only. A little longer opening to the Balkans today on 70 MHz providing two new squares with JN85 and KN06! 😎 Both are well under 1.000 km so needing a higher MUF to work (at the same time there was a short 2 m ES opening between PA and YO utilizing the same clouds).

Sporadic-E on 2 m again

Not very active during the last 2 weeks. Either no condx or me being too busy with QRL stuff. Just caught two smaller 4 m openings last Sunday (June 14) to Finland in the morning and Greece in the afternoon but didn’t bother to report separately. 😉

More luck today! 2 m opened to UA4 in the morning. All in & out, not well positioned here but good enough to make a few QSOs. 😎 Later on it suddenly opened to Greece, too! Imagine how surprised I was when SV2HNH called me while still beaming to Russia. 😀 Propagation to SV was not stable either but good to catch two openings in a row. A few QSOs on 4 m afterwards, but it all remained quite patchy …

A new square on 6 m & some thoughts

Only one QSO today: TA7OM from KN80 providing square #690 on 50 MHz.

Despite this I haven’t done much on 6 m this season yet. Seems I somehow lost interest in the band as almost all activity has shifted to FT8 only. While I use FT8 myself and see it’s advantages for weak signals it doesn’t make much sense when signals are strong. And for working the real DX (despite JO73 being a 6 m blackhole or me just always being impeded when there are condx) my 400 watts and 6 or 8 ele Yagi usually don’t cut it on FT8, there are simply too many stations calling in limited space (and QRMing each other). How much easier is it all on CW where you can make up for less signal strength by good operating practice? Best example has been 7Z1SJ a few days ago: while I called him endlessly on FT8 without success he was an easy catch on CW when he changed mode …

No, I’m not going to buy a bigger PA … at least not for that reason. 😉 I’m rather thinking of taking down the dualband yagi and putting up a (bigger) dedicated 4 m only beam instead. I can still use our 8 ele long-boom yagi for 6 m then but parallel operation (i.e. Uwe on the 8L and me on the 6L from the duo yagi) wouldn’t work anymore. Guess I can live with that …
