A bit 6 m DX at least

There was a great opening to the Middle East on 6 m this morning. Unfortunately not much activity …

07:35  9K2NO         LL39XG   599   559    6 m.   CW          3813
07:41  A45XR         LL93DO   599   599    6 m.   CW          4931

Both were reaching real 599 signal levels. It’s quite rare that JO73 gets these kinds of signal strength’! Neither new squares nor DXCCs but very enjoyable nevertheless.

Six was hot all day. Great ES propagation across all Europe with the IARU Region 1 50/70 MHz Contest taking place and thus lots of activity. Handing out a few points every now and then I managed to do some 130 QSOs without much effort. Imagine what could have been possible taking part seriously. 😉

Great Sporadic-E on 144 MHz again

es-loganalyzerLucky me! Mother nature was calling early this morning and before going back to bed I just checked the MUF on DXMAPS on the smartphone. Glad I did! There was already some ES going on 2 m. Quickly switched on the remote station but it took another 15 minutes until the band opened in JO73. Unfortunately I had high SWR on the remote antenna. :( So could only run 10 watts first and later about 100 watts when things warmed up. Seems a bigger problem in the connection between the 7/8″ coax going up the mast and the last few meters of Aircom+ cable. Heiko, DG1BHA, already tried fixing it twice during the last few weeks but the error always returns sooner or later. Time to fix it permanently! So hope to be able to squeeze in some time during the next visit in about 2 weeks when driving the 700 km home again …  Nevertheless managed some nice QSOs and even worked two new squares … it’s been a while since doing so via Sporadic-E. 😎

Played around a bit with DL4MFM’s Log Analyzer, see screenshot. The following great QSOs were made in two sequential openings, the first one lasting about half an hour to LZ and the second one for another 45 minutes to SV about an hour later:

CW-Fieldday & WRTC antenna tests

Spent the weekend up in JO73 again. Met with Paul, DL5CW, Falk, DK7YY and locals Heiko, DG1BHA, and Uwe, DL3BQA. Wanted to do some antenna setup testing for WRTC 2018 which Paul is the Antenna Director for.


Paul, DL5CW, mounting the Spiderbeam

Lots of stuff to install and still lots of open points to improve for future installations. Weather was fine all weekend long but doing all the antenna work in temperatures around 30°C was less pleasant. Although we were quite exhausted we still spent some time activating DKØWRTC/P in the DARC CW-Fieldday. Stopped early after reaching QSO number 1000 (yes, some 32 dupes included) as we still had to dismantle everything. Also sent in the log just as a fixed station. We did have generators to supply the radio with power on site but really didn’t want to miss all the comfort of a fridge, coffe machine, a.s.o. after all the hard work thus took electricity supply from a hundred meters away instead. That also saved us from needing to refill the generator every few hours … 😉

CQ WPX CW and some Magic Band frustration

Unfortunately I couldn’t make it to the QTH this weekend so only spent some limited time in the CQ WPX CW remotely. Great Sporadic-E conditions all weekend long so kept going on 10 m single band and managed a whopping 850 QSOs. :) Of course there was not much DX in it, a few South Americans, some nice (but few) Caribbean DX and a bit of (the closer) Asia. A VK5 called in on Saturday, another VK7 on Sunday, providing an ODX of about 16.000 km. Also great to find a lonely XRØYS search&pouncing Saturday evening when the band was almost closed. 😎

A detailed analysis is available here. Should be good enough for a TOP 6 finish worldwide. Only after the contest I recognized that I even broke the current German record, who would have thought that? But the margin is quite small so will have to wait and see how much the log check will take away and if it will still be a new record by then (I think not).

I stopped every now and then during the contest to monitor 2 m for ES openings. There were indeed some openings but I was always too close to the ES clouds so no QSOs on 2 m this time (but great short skip on 10 m … worked OK’s and DL’s not further away than 250-300 km with s9+ signals!).

Saturday afternoon provided UN7AM/LN53 for a new square on 6 m while doing a short propagation check. 😎 Sunday morning saw a great opening deep into Asia on 50 MHz. Could hear BDØAAI (z23!) at 529, BA4SI at 539 and BVØWPX at up to 559 but couldn’t raise them, thus missed 2 new DXCCs and 3 new squares, that was quite frustrating. :(

What a great day on VHF today …

Luckily Corpus Christi is a local holiday overhere so I had the day off. 😎 Waking up at 5:30z I was not sure if I should get up or turn around for some more sleep. Seems it was a good decision to get up … First there was a very early ES opening on 144 MHz. Although it lasted only about 2 minutes in JO73 it was good enough for a nice QSO. 😉 Later this morning we had some great double-hop Sporadic-E on 50 MHz to the east allowing me to work MN52 & MN62 for two new squares, now 640 in total on 6 m. :)

06:52  RA6C          KN94GT   59    59     2 m.   SSB   ES    1990
09:45  EX8M          MN62WT   599   599    6 m.   CW          4446
10:04  UN6T          MN52QV   599   599    6 m.   CW          4276
10:07  EX9T          MN82SD   599   599    6 m.   CW          4731
10:15  UK8OM         MN51UA   599   599    6 m.   CW          4423
10:16  EA8DBM        IL18OH   59    59     6 m.   SSB         3747

After that the MUF went down quickly but still 6 m was open all day long. I didn’t work anything else, was doing some QRL things meanwhile. Late afternoon 4 m started filling up with strong OIRT signals so I kept the beam dir East and threw an occasional CQ call on 2 m every now and then. At 16:33z Artur, UR3EE, answered my CQ starting another 1 hour ES opening on 144 MHz. 😎

16:33  UR3EE         KN88DC   59    59     2 m.   SSB   ES    1648
16:46  UR3VKE        KN69OA   59    59     2 m.   SSB   ES    1400
16:47  UR5VFJ        KN69OA   59    59     2 m.   SSB   ES    1400
16:56  UA6LJV        KN97LE   59    59     2 m.   SSB   ES    1872
16:56  RK6MF         KN97RC   59    59     2 m.   SSB   ES    1909
16:58  UR5EDN        KN78SH   59    59     2 m.   SSB   ES    1588
17:03  UZ2HZ         KN69RA   59    59     2 m.   SSB   ES    1416
17:12  UC7RAA        KN64SO   59    59     2 m.   SSB   ES    1696
18:27  FM5WD         FK94MP   559   599    6 m.   CW          7721

Signals were strong but never lasting very long, so pretty much all in & out after a few minutes. Nevertheless great fun! Then working the first Caribbean opening this year on 6 m via triple-hop ES later on was a nice end to a great DX day on VHF. 😎

UR3EE/KN88 booming in via Sporadic-E on 2 m (cut out white noise in-between):

Caught the first 2 m ES opening this year …

esFinally caught the first 2 m ES this year! :) 6 m had been hot all afternoon. Later also 4 m opened up nicely. It was kind of masochistic listening to all the activity on 70 MHz and not being able to join the fun. :( But it was a good indicator on how conditions would evolve. Around 16z OIRT started heavily on 4 m direction east so I kept an eye into that direction. Also 6 m was full of TV birdies which suddenly stopped while OIRT was still strong – a clear sign of rapidly rising MUF as with higher MUF skip zone shortens dramatically on 6 m meaning being in a distance to the ES cloud you just won’t receive the low VHF QRM anymore, you would need to move closer to it. But hey, then you would be too close for 2 m over the same cloud. 😉

144 MHz opened at 16:28z but it only lasted for about 1.5 minutes, just enough to complete a CW QSO with US6IEW. The band was more consistent further west, I was not in a perfect position in JO73 geometry-wise. Five minutes later US6IEW popped out of the noise again answering my CQ call, this time in SSB. Band closed again after 2 minutes or so. It then took another 10 minutes to open again, this time for about 8 minutes.

16:29  US6IEW        KN98FA   599   599    2 m.   CW    ES    1794
16:35  US6IEW        KN98FA   59    59     2 m.   SSB   ES    1794
16:48  UY1HY         KO6ØMA   59    59     2 m.   SSB   ES    1343
16:50  US4IEK        KN87UX   599   599    2 m.   CW    ES    1747
16:54  UX5UL         KO5ØFL   59    59     2 m.   SSB   ES    1153
16:55  US4IEK        KN87UX   59    59     2 m.   SSB   ES    1747

UY1HY and UX5UL were quite short distances on the same cloud that was used by West-DL and PA to work further into Russia and East Ukraine. Seems there were 2 active spots or one really big cloud with different active zones.  Here are a few audio recordings again:

US6IEW 144 MHz Sporadic-E:

UY1HY 144 MHz Sporadic-E:

UX5UL 144 MHz Sporadic-E:

US4IEK 144 MHz Sporadic-E:

The MUF dropped quite rapidly afterwards but 6 m stayed open until late into the night. Sporadic-E even linked into a good Caribbean opening around 11 pm local time … albeit not on 6 but on 10 m. 😉

Another world win: SARTG-NY 2016

It felt like ages until the SARTG contest committee finally released the results of SARTG New Year RTTY Contest 2016 now. I have been checking their website every now and then for the last 4 month’. 😉 Took part in that one for the first time ever so was even more astonished to having won it world-wide – wow! It didn’t even feel like a big deal operating back then. 😎 And it was a really pleasant experience and the duration of only 3 hours made for some leisurely contest activity on New Year’s day.

EA6/PA2CHR for square #530 on 2 m

Seasoned VHF Dxpeditioner Chris, PA2CHR, was on tour again, this time activating the rare squares on Menorca Island, i.e. JN10, JN20 & JM29. Unfortunately I could not be QRV when he was in JN10 & JN20 but had a chance to catch him this morning on Meteor Scatter from JM29 for square #530 on 2 m. Thanks Chris! 😎

WIA Awards

Applied for and got a few nice awards issued by WIA (Wireless Institue of Australia). They have a great online system to apply for the awards using ADIF uploads and getting the contacts confirmed through LotW and/or eQSLs. The awards are issued in PDF format nowadays so you have to print them yourself.

I was most interested in the WA-VK-CA-HF as it is really beautiful and demanding to work. I had to wait and catch the VKØEK expedition a few weeks ago and get them confirmed on LotW to finally be able to apply for it! 😉


Another one I really like is the Grid Square Award – looks great on the wall, too!


They also offer a number of different DXCC awards for Single Band, Single Mode, 3-Band, 5-Band and 9-Band with mode combinations (see a few examples below) as well as a VHF Century Club Award, too …

DFØFA VHF May Contest ’16

Out again on the local hilltop in JO73CF. Ran short of operators, only DGØZB, DG1BHA, DH8BQA, DL3BQA & DL5CW active this time while DK7YY & DL9USA were prevented. Activity was quite bad, not happy with the result. Probably due to the fantastic weather, can imagine a lot of guys were bound in other activities. We got some nice sunburns! 😎


Eager to learn how the competition finished. There was a nice Aurora opening Sunday evening (see above). Too late, could have used the points during the contest! 😉

No 70 MHz permit in Germany this year :-(

The bad news is official now: For some (political) reasons there won’t be a temporary permit to use the 4 m band during this year’s Sporadic-E season in DL. What a shame. :-(

Let’s hope we will get a few good 2 m ES openings instead, first one was today, although more southerly, i.e. between France and Bulgaria.

TY – Benin #138 on 6 m

TY2AC_end_front_finalHad the first 6 m ES opening of the season today. The band opened nicely from here into Southern Europe, i.e. 9H & IT9 around 15:30z with S9+ signals. Saw TY2AC spotting southern Europe stations himself on the cluster. He finally settled to call CQ but heard only a few MS reflections once in a while. Stayed tuned to his frequency while doing other things. Around 16z he finally came out of the noise but never strong enough to QSO, just got ??? in return to my calls. It took another quarter of an hour until he rised up to a nice 559 signal, albeit with QSB. Took just one call to work him then. Propagation seemed quite localized, he didn’t get much callers, it was mostly northwestern Poland and northeastern Germany working him with JO61 stations being the most southern (at least as long as I monitored).

TY2AC on 6 m:

Even 4 m opened up later, quite early in the season! 9H6A (guest op’d by PB8DX) was very strong on SSB for more than half an hour. 9H1PI CQing on CW was much weaker.

9H6A on 4 m:

It’s a pity 4 m is still not allowed again in Germany yet. Hope RegTP will offer a temporary permit for this summer again anytime soon!

VK0h/Heard Island #309 & FR.j/Juan de Nova #310

Besides WPX-SSB almost no radio activity overhere since returning from Aruba. Lots of QRL and not really up for the hobby. So had to force myself to switch on the radio a few times at least not to miss the VKØEK and FT4JA expeditions for two ATNOs. Condx are rather poor but the guys have good ears. Pileups seem to be down a lot now compared to the first few days. Even heard them CQing a few times without any takers today …

No activity at all during the last 4 weeks. Just too much QRL and not really up for the hobby. But wanted to do a few QSOs during WPX-SSB at least. As you might know we’re sharing our station. This time Uwe, DL3BQA, had the choice of band and started as DMØY in the SOSB15 category. 10 m was a dead loss, condx just sucked. 20 m is really not my cup of tea for going single band in an SSB contest and for the lower bands it’s still just simple wires. Thus decided not to go single band but just do a few QSOs every now and then as SOAB(A) on the remaining bands. Goal was to put up 1 million points for the BCC club score. Well, that was already reached before going to bed Saturday evening so next goal then was 1111 and then 1234 QSOs for a nice number. 😉 But couldn’t stop it as I had a nice run going into North America late Sunday afternoon so set yet another new goal. 😉 That finally was 2 million points plus some 5% on top for the usual logging errors. And here we go, suddenly some 20 hours of BIC time gathered … 😉

Recorded all the QSOs again and uploaded them to http://qsorder-k3it.rhcloud.com/ if you want to take a listen. Wished more people would use it. Sharing contest recordings has never been so easy! 😎

P4ØFA QSL card variants

Finished the artwork for the P4ØFA QSL cards, too. Still undecided which one to use, somehow I like them all! 😉 Ordered a small batch of cards for every design to see how they look like in reality. It always makes a (small) difference having them full format on a screen versus having them printed on 14 x 9 cm cardboard. My favourite is the first one although the iguana on the coax cable has something special to it, too. 😉

Aruba Contest QSLs

Finished the QSL design for our contest QSOs. Paul is using MS Publisher for his QSL artwork while I’m usually doing it with my (very old) copy of Paint Shop Pro. He was so enthusiastic about it when discussing the QSLing topic on Aruba I decided to give it a try, too (it’s included in my Microsoft Office Suite anyway). And indeed, it makes a few things much easier and has nice capabilities especially using WordArts for some nicer text designs. The learning curve was quite low as I’m used to the MS Office software anyway. So big thanks to Paul for the hint! 😎

We decided to use the same frontside for both the P4ØFA and P4ØXM contest QSOs. I analyzed the logs and among the > 10k QSOs done we only had about 300 guys who worked us in both contests, WPX-RTTY and ARRL-DX-CW. Assuming not everybody will QSL anyway, the number of guys who get the same card is really neglectable. So it was not worth the effort to design different front sides.

We *will* have different designs for all QSOs made outside of the contests. The overlap there is much bigger and of course we do not want to bore people getting the same card although they worked 3 different guys. 😉

Paul had a nice idea for his QSL card. I suggested to put a smiley behind the sentence as I’m sure there *will* be people who don’t get it’s intent. 😉
