Story of the OK2KKW's May 2007 VHF subregional contest

This contest was dedicated to testing and searching for new ways. New technical solutions, new bands and new operators. After our antennas and other hardware were stolen last year, members of our small club weren't able to restore all our stolen equipment due to lack of time and money. We had been building this equipment for several years and it was not possible to replace it in so short period of time. That's why we stand at the start realizing this handicap, on some bands at least. First of all we made decision to resign on the 2m band as a contest band. We were thinking of not to build this band at all, but in the end we decided to do it because it would be good idea for our new less experienced young operators, who almost never operated our station during big contests in which we were pursuing good results.

This contest had actually started some time in Autumn 2006. After some unsuccessful attempts to build a truly functional, stable, reliable and repeatable PA for 23 cm with GI7b tube I gave it up and started looking for another solution. Not that the GI7b would be a bad tube but I found out that this tube designed in 1943 amplifies on this frequency just due to positive loop reaction, which makes temperature instability and non-linearity. Also the efficiency is very poor due to long electron transition time, which is in strong opposite to requirement for a stable and reliable PA. After longer effort I managed to construct a repeatable neutralization and so dramatically improve the temperature stability, but gain decreased to just a few dB, which is of course not acceptable. Realizing this I decided to look at it in different way and make something small solid-state in the short time. However, even that work took me a couple of months. Nevertheless the respective result showed up at last. At least I thought before the contest, hi.

The same long preparations as were made in case of putting 23cm equipment into service (we also had to find a new suitable parabolic dish for this band which would be transportable to our contest qth regularly so it wouldn't become a new victim of "metal pickers", hi) OK1BAF had to do to develop a new, more sophisticated 3kV power supply for 2m PA, because the old one was stolen before the Field day contest 2006 as well. Unfortunately, Honza OK1BAF was overbusy so this objective as well as the objective of Jirka OK1JFR to set up a new small trailer for mast transports were not completed in time. The pleasant surprise in this list of unrealized objectives was the announcement of our other Jirka OK1ZAD (he is still bit an external member) that he had finished his new 13cm equipment and he wanted to test it in our contest qth. Thus, our contest participation increased to unusual number of 5 bands and we had to start resolving the funny question where to place it.

Luckily the weather forecast was fair and our contest QTH should be a quiet island of good weather among surrounding fronts. We choose the extended (and not luckily as we discovered afterwards) variant, that all bands would be run from the bunker and just 2m band from our cabin. The weather forecast came luckily true (compared to the rest of OK) and we were enjoying good and dry weather. Of course things got worse at last. As usual the bad luck comes in series of three. We should have realized that as the failure of OK1BAF in preparation of the big 2m PA (which came only few days before the contest, because the primary coil of PA transformer for all driving voltage got broken and a new transformer couldn't be wound from one day to another) was the first one. The second one was damaged FT1000MP during the transport, so the expensive transceiver become unusable.

Because we didn't have another "2 way exhaust" FT1000MP and so we weren't able to use our transvertor with crystal filters, we decided to run the contest on 2m just for fun with OK1BAF's FT897 with a small driver PA and a small antenna. We hoped that QRM caused by this middle class TRX to our neighbors was tolerable, hi. In 70cm PA we used a new tube GS31b instead of the old GI14b. On 23cm we used our second FT847, transverter and two new solid-state amplifiers, on 13cm Jirka's FT817 and transverter on the mast with 10W PA. The 3cm band was equipped with over 27 years old FT290R and transverter with 6W power out on the mast. All the antennas you can see on the left picture.


Just as the contest started, a serious problem occurred. The 70cm PA together with higher power requirement from the new 23cm PA's pulled down the mains voltage in our one phase feeding from 230 to about 140V (!). It was caused especially by new solid-state PA's with switch-mode power supplies and the UPS placed before the 70cm PA. This kind of power supplies drain (in contrast to linear power supplies used before) more current when the voltage decreases causing the domino effect draining more and more current until the voltage is too low to keep the power supply running. Practical experience of this avalanche effect forced us to suspend the 70cm band operation and very soon we sent our messengers to Karlovy Vary to look for a regulation autotransformer to help us to increase the voltage at the end of the 400m long power line. Until then we had been running 70cm with the barefoot FT847 only, without the PA. At about 20 UTC we managed to increase the voltage, but in a hurry we made a minor mistake, the voltage raised to some 275V (!). Immediately the 10A fuse burn out because the solid-state PA's have varistors connected to their inputs and for such voltage they are virtually a short-cut. But luckily all equipment survived. The input voltage in our house was adjusted to 245V eventually and we could start contesting again. Unless we drive the 70cm PA more then about 200W out, all is running ok even if the network voltage is fluctuating "a bit". You can see it if you click on the right picture >>> (the middle of the scale is 150V and the right backstop is 250V).

But let's go back to the contest beginning. We started and even better Matej, OK1TEH on 23cm was making plenty of good contacts. It's fine, new PA's need to be run in. You can read more in his report:
 ...................................................................................................................................................................................................................................................

I was looking forward to this contest very much because I run my last serious 23cm contest one year ago and during the UHF Contest 2006 we used just 6W QRP and I was focused to 3cm mainly during this contest, the 23cm was operated by Jirka, OK1ZAD for most of time. One year back we used old PA with GI7b tube by OK1VMS with maximal output power about 120W with very small reliability as the tube liked "the bang sound" very often. The antenna was full 160cm aluminum dish which was stolen by the "gypsy guys" before the Field day contest 2006, too. We had to look for a substitute. At last we managed to get a new wire WiFi grid dish with gain about 19dBd on 23cm, a bit smaller then the old dish. The advantage of this new antenna is low weight and especially the small surface suitable for usual strong mountain wind.

I tested the new solid-state PA's during the 1st subregional contest in March together with the feed by DL4MEA. The main reason was the seasoning test in long contest operation. The new PA successfully came up to expectations. Also I tested the PA during my 1st 23cm EME qso with Al, K2UYH on JT65c. Another good news was the 2nd PA's "brother" so I had the serious reason to enjoy the next contest indeed :-))

We arranged the equipment pretty early before the contest start so we had the time to set up all the important funny thing like a CW keying from the PC, computer network, rectification of antennas to the beacons etc. The first qso before the contest was made with the Zdenek, OK1DFC from OL4A club, who told me that he would run the contest with the "QRP" power of 300W because he didn't have the PA driver for his 800W QRO PA with TH tube. Then I made a quick QSO before the contest, some lunch and contest was ready to be started.

14:00 UTC We began the contest on our traditional frequency 1296.215 MHz, new amplifiers were running OK, what an enjoyment against the old GI7b PA. In the first hour I made standard qso with OK2KJT and a nice SSB contact with S50C. I made 26 contacts in 1st hour, it wasn't bad at all.

15:00 In the second hour I logged in the ON4KST chat, where I managed to make sked with Franco, I4LCK/4 (the MP3 record is here). This QSO was almost without any problems, I just asked for RST+NR again and 705km qso was complete :-). Next I made a
QSO with guys from OM8A, they had the strongest 23cm signal from all OM stations, congrats. On the chat I saw, that there was a good rain scatter in the OE area and Claudio was working dozens of long path QSO's like with OK2M, DM7A, DL6NCI simply all stations around us ;-). So I ran to the Jirka's OK1ZAD 13/3cm van more frequently, because it was his first contest on 3cm. Unfortunately this RS QSO was not completed. So at least we made contact with Tom, OK2PWY. This my "foot band changing" was lucky in one way, the 23cm PA's had time to get colder.

16:00 The nice qso with OK5Z was made also on the higher bands and even further I was called by SP6HED, which is more valued contact then any from PA because of massive Klinovec hill in the East direction. On the other hand it was the only one SP worked in the contest. Another remarkable QSO was with Thor from SK7MW, unfortunately we didn't manage to make it on the 13 or 3cm bands. Later SK7MW wasn't QRV on the higher bands any more because of lack of operators. This is the problem we know very well, too, hi. After the QSO with SK7MW I was called by Roberto, IZ4BEH, and unfortunately when I started sending him report we had the power-line failure. Another problem was with my notebook which have the old damn none operational batteries so the contest log crashed as well. The reason was simple, our UPS, which had to balance with the soft voltage in our power line started peeping like a piggy at the pig-sticking and then it failed completely. So we made decision to look for the the autotransformer in the near city. We sent Honza, OK1BAF with OK1XNG and 70cm had to stop in favour of the 23cm band. Unfortunately later when guys went to the cabin for transformer mounting and power line cutting, they didn't phone us about it and the IZ4BEH was gone.. Funtunately our contest software VUSC have robust backup, so the data was saved properly. Meanwhile Honza, OK1BAF wanted to please us with more voltage and sent us 270V causing more problems. In the end it took over 1hour to get into the contest again.. No need to mention that power line drop-out cost us on 23cm in the best pile-up time 20 to 30 contacts for sure..

18:00 UTC All machines are working again, but there's yellow eye of the overheating LED diode flashing the on the PA panel. I resolved it by opening of all windows and door of the contest caravan. Just it's a bit windy and colder now ;-) Another caller came on SSB with callsign PA0WMX, it was bit weaker signal then usually but without any problem. The best star of this hour were guys from the IQ1KW (the MP3 record is here). I made them with fantastic signal 59+++ on the distance over 772km. They had burn their 13 cm band so I sent them the 70cm sked only :-) And how about the other BIG-GUN contesters? At 18:26 I called DL0GTH. Our power-supply problems helped them to the leading by about 15 contacts. It isn't bad at all. Next stations in my log appeared the gang of OM0C (the MP3 record is here) and OM3KII. I have to say that we were trying it with OM0C on 13cm many times, Riso heard us very well but our 13cm equipment is deaf (the attenuation was about -10dB) so that qso wasn't completed. Meanwhile there was some QRM from the DM7A, as you can hear on the following record during the tuning from the frequency .215 to their frequency on .180 (the MP3 record is here), from DL0GTH and surprisingly also from the OL4A when the antenna is beaming their direction. BTW, I read on the ON4KST chat: 2007-05-05 18:36:20Z OL4A-1 Zdenek OK1DFC TEST 23cm 400W and 180cm dish, although he mentioned 300 W power before the contest. What would be the difference of our contacts number? I'll let surprise me a bit later :-). And where are the guys from the OL2R club?

19:00 The contacts rate is getting down and the log is filling slowly. I enjoyed nice QSOs with OZ3ZW from JO54 (the MP3 record is here) and DL0VV from JO64.

20:00 First I made our well known friend from the 23cm NAC DL6ABC and then I'm called by the OL4A. The unbelievable has come true and I found out that I was leading by 25 contacts :-))) After that I'm surprisingly called by the Tom, OK2PWY (the MP3 record is here) for the 13cm sked with his father OK2BFF :-)

21:00 My joy was a bit calmed down when the guys from DM7A called me. They had over 30 contacts more. Well we'll see later.

22:00 It's almost midnight of the local time, a good time for the some nice QSO to the S5. This hour I made good QSO's with S57C and Jože, S51ZO. They weren't 59+++ as usual, though. Really bad condx to the East and East south. And of course the attempt for 13cm contact had failed.

23:00 The band is getting louder once again and I managed to get a good pile up to the JO42 and JO53 area. After a nice QSO with Norbert, DL1SUN I QSPed the sked to the Jirkas SHF van and he worked him on 13cm with outstanding signals. I run to the van once again but my 3cm attempt this time wasn't successful, sri ...

00:00 The GMT midnight came unobtrusively and the 2nd round of the contest, too. The wind outside the caravan is calming down and because I saw the DXcluster full of the super DX contacts between the EA1 and OZ on 70cm I was looking forward to the morning crown of Spanish stations from the Pyrenees :o)))

  

Early morning

Jarek woke me up to make a operators change. He told me he had almost completed qso with F1PYR/P from JN18 which could be over 780km. When I arrived to the contest caravan I found the reason why the QSO wasn't completed eventually. In the second PA quiescent current wasn't running. In other words, the PA was burn out and crashed.. The contest is continuing only with one PA and dish since. This PA gets often overheated, so I keep the output power on about 80W.

06:00 The start is not bad, even with smaller power. It is possible to work a few nice stations like a LX2LA, SM7ECM, IK3COJ (the 3rd Italian station the MP3 record is here) and PI4GN at last, too (the MP3 record is here).

07:00 The contest log fills by the DR5A and DL1SUZ, unfortunately the 13cm contact could not be completed again and after that at 07:42 I had sked with PI4Z, QRB 637km (the MP3 record is here). Coen, PA5KM an old friend from the ON4KST chat was working there. Contact is fast and FB. I just didn't know a movie of this contact was being recorded in JO11. As you can see, our 80W signal was banging on the S-meter like from a local station :-). Pity that the 2nd PA wasn't working on Sunday. I could be beaming to PA only and the contacts to other directions wouln't have eaten my score. If you want see the movies with the records of our signals in PI4Z on 23cm, click on the picture on the right ->>>

08:00 After PI4Z I managed to make a QSO with M1CRO/p (the MP3 record is here) (alias G0VHF). The operator was Robin, G8APZ, well known DX operator from many of 2m MS expeditions to rare squares, also under the callsign F1VJQ. Will the 23cm contact be possible? Really, after some time we made it, it was a long but completed qso. The distance was reached with the nice signal in peeks and it's been the new contest ODX 819km :-)

Next station for the plane-scatter test is John, G3XDY (the MP3 record is here). This contact was completed very fast with perfect signal as usual, TNX! The QRB = 827km which is the new ODX again and so it stayed to the end of the contest. After that I made a qso with PI4TUE (the MP3 record is here). We were trying it with PI4TUE on the 3cm immediately afterwards, we hrd them with UFB signal 599, but they couldn't get our contest number. I know, that PI4TUE is the strongest 3cm station from the PA with some 25W TWT QRO power. It's pity anyway. This qso could have been our 3cm ODX with distance of 527km.

09:00 Another fine hour with pile-up of PA stations like a PA6NL (the MP3 record is here), PA0EZ (the MP3 record is here), PA0S (the MP3 record is here) etc. (Unfortunately, 13cm is still elf-struck.).

10:00 I made a nice qso with OZ2LD and at last on SSB with Roberto, IZ4BEH across the Alps on the distance of 662km! (the MP3 record is here). So it's the 4th Italian station and I hope I'll work the same number in the next contests :-).

11-12:00 Good time is continuing with 9A1Z, QRB 510km (the MP3 record is here) with his 1,6 W (!) QRP and with first ON in the contest which was ON4SHF/P (the MP3 file is here), only ON4HRT wasn't heard at all. Who was coming the next? I'm trying the next plane-scatter QSO with the F6DKW (the MP3 file is here) a and really another fine contact was completed OK. The distance is about 784km, FB! The next worked station was PA5AO, and after contest I found out that it was the ODX for him. But to the 900km long qso with YU1AU who worked with DM7A remained just a fantasy for me. By the way we didn't work any of the YU station even on the 70cm at all. Where was the YU1EV? Was he QRV on 70cm and higher bands?

13:00 The last hour of the contest and the good time is going on. At last I worked with UFB signal PA0BAT and after him we QSY to the 13cm. He heard us fine but it's a one way test, see you in the log next time... Next 23cm was answering to my CQ, it's S59R (the MP3 record is here) and the last contest qso was made with the DG1BHA from JO73 (member of the DM0Y club, ex. DF0TEC).

14:00 The contest is over and the score rose up to closely to 40000 points and some 132 contacts. And what's the score of the DM7A? After the contest I found that they worked about 170 contacts and about 9000 points more. You know, Fichtelberg is an excellent hill and they are excellent operators, congrats guys! After that I found out the score of the DL0GTH gang. They are said to made incredible number of 195 contacts!! How it could be possible? I know that they have closer distance to the wealthy JO30 area and they used to work long distance qso to the S5 and 9A and their hill Schneeberg is naked like an apple. Anyway how it could be possible, when they have the ONE 190cm dish and some 200W PA only (even more I wasn't able to see them make any aircraft scatter skeds on ON4KST)? Well what's an inspiration for the next contest hi :o)

And what is my final contest evaluation? It was a successful contest with a lot of wonderfull contacts. The only bad thing was the burn-out PA, painful. I hope the reason will not be fatal for the expensive solid-state circuit.

73 and cu in the next contest under OK2KKW call de Matej, OK1TEH
...................................................................................................................................................................................................................................................

So this was the contest view of Matej, OK1TEH. The damage of the 23cm PA at night was painful and the final unlucky triplet. The break down of a well started contest was one problem. Another point of view is worse. It's still not clear, what was the root cause of the failure. To all appearance there wasn't any reason for it like overheating, bad SWR, voltage or so.. Until we find out what was the real reason of the solid-state PA failure, we have really serious problem which can occur again at any time.

But this contest was not run on the 23cm only: on 432 MHz the contest was continuing calmly and as a usual. We lost lot of points in the contest beginning due to problem with unsuitable voltage but after that the contest was going on in the old way even with the small power. After all we finished with almost the same score like in the same contest last year. The conditions to the south were poor, the DL activity was lower but on the other hand it was enjoyable, that the OL7C didn't make any of QRM. The guys from DM7A were pretty strong but their frequency was around the .160 and because we have them in our most uninteresting direction to the north Poland, the QRM was acceptable. It was worse with QRM from the Michal, OK1GHZ on Klinovec. Not only spurious up to S9 but even more when he swithched to the transmitting, the noise poped up to S7 which was killing our RX mostly to the east (sri OK2 stations..). So we are apologizing to all stations from this direction calling us without success. The 432 MHz result isn't so good after the several hours lost and the 200W power, even the km/qso average is much lower then usual but the operation made the good support for the 23cm band and we are with this worse result satisfied. We are satisfied even more with our 144 MHz presentation. Guys (OK1BAF, OK1JFR, OK1XNG) had good opportunity to enjoy the contest without any stress from the hot operation for the best score so they were satisfied as well. On Sunday after lunch, when all were fed up with the two meters QRM we packed up the station. Even now we haven't decided if we should send our 2m log as the check-log only as it was the "just for fun" operation, hi.

 

The 13 and 3 cm bands were operated by Jirka, OK1ZAD. He was testing his new 13cm equipment and for the first contest on this band it was working more then properly. It was worse with the 3cm band, because Matej was sending him plenty of skeds via the VUSC contesting program and Jirka, who was operating 3cm for the first time ever was overwhelmed. So we lost some good potential DX's which could be made via the rainscatter, especially to I,S5 and 9A. Besides, we didn't complete the QSO with PI4TUE on 3cm even if we copied him very well. PI4TUE was booming very much but he couldn't get our 6W QRP signal (he has 25W TWT). Maybe we had to hear something on the air. But the 3cm wasn't that critical. Jirka had proved, that his new 2320 MHz was working during the whole contest and the frequency was very stable. He needs to make something with weaker RX but it can be easily improved before the next contest. What's an interesting lesson learned from this multi-band experiment is that if you want a good results you can't operate both bands from the same table and computer. To make a complete qso on the SHF bands can take a lot of time and in the meantime you're missing the skeds for other bands coming typically every 10 minutes. The other station use to have little patience to wait so long time before you complete the other qso. So now is clear the we'll need (if we have sufficient number of operators) to separate these bands for the better results in the future and both stations have to be equipped with a separate rotator and PC.

But that's not all. There are even further bands to report about. As agreed before, Guys from DM7A (DH1FM, DM1KL and DG3UH) visited us. For the talk, common beer and mainly for the testing of our qth for the EHF. They brought the equipment for the 47 and 76 GHz, so we had first and rare occasion to try the fascinating operation on such a high frequencies. Even with the few microwatts of power. The first problem was the antennas orientation so we used a good old photo camera with the flash to make a target for the other station to aim their antenna. We made a sked via the FM handy on 70cm and sent the signal back.At last both stations were pointed in the right direction, elevation, frequency and ready - we get an outstandingly strong
signal. So our boss, OK1DIX (on the picture on the right) has the opportunity to try the joy of our first qso under OK2KKW on
the 47 GHz abroad. We worked Hartmut from the DM7A and only few minutes after it we we made an easy contact with Pavel,OK1AIY/P. Both signals were S9+.

But the miracle time isn't over yet. When it works on 47Ghz, why not to try it on 76 GHz? The power is about a half but the antenna have more gain - and really, Vlada, OK1VPZ is starting the qso. The antenna pointing is a bit more difficult but even on this band we succeeded to find the signal of the DM7A and complete the contact, too. It's not worth to talk about it, try to listen to the movie, how we were copying the Hartmut's signal on 4mm.

But we weren't radioamateurs if we hadn't tried the next contact. So there is proposal on the lower band to the OK1AIY - Pavel let's try it even on 76GHz. The right antenna pointing is even more complicated. Pavel is pointing on the Klinovec crossways through the double-layer window which bends the waves to another direction and we weren't sure if we had the synchronized frequency. Even more the both transvertors have the intermediate frequency on the 144 MHz band, which is heavily used by the contesting stations. Finding the very weak signal in this chaos for properly antenna beaming is not an easy job. After the 40 unsuccessfully minutes, the resignations is coming slowly. Let's try the last test - and now Pavel lets his TX on the klinovec on. Sebastian, DM1KL is carefully pointing the antenna and OK1VPZ is tuning the band. And about 80 kHz then it was expected we found a very weak signal. I'm telling Sebastian to point the antenna properly and - yes that's it! After the correct pointing the signal is peeking to S9 and I start talking to the mike. Signal in opposite to 47GHz is unbelievably stable, similarly to the 2m. We're exchanging the contest code with Pavel. The signal strength is outstanding and I start chating with Pavel as usual. On 76 GHz band OK2KKW has even two DXCC now! To complete DXCC is still somewhat missing but we made the first successfull step :-). But after some time it's getting really cold, so we are changing greeting with the Pavel because guys from the Fichtelberg are asking him on the 70cm for the next test with them. So Pavel cu maybe next time!

For the disbelievers: you can see the video record of part of our 76GHz contest contact between the OK2KKW and OK1AIY/p.

 

On the beginning I wrote, that this contest was dedicated to testing and searching. Thanks to Jirka and his 13cm rig we faced a new situation. Our usual WIFI connection link, which we used for the computer network between the contest place on the bunker and about 400m far cabin could not be used any more. We prepared our old cable modems, which can the "outstanding" speed 64kbps, but OK1BAF got us a new gadget - PLC modems! We attached them to our long power-line cable and what in hell - it's working! The connection quality is excellent even if we have the autotransformer in the cabin and a lot of switching-mode power supplies running on the bunker. The connection speed is about 10Mbps. So don't be fools - PLC is a good thing for VHF/UHF hams :-)) No QRM on any band we used at all. Lada OK1DIX who is the member of CAV organization is watching the PLC with some contempt first but at last he appreciated the unquestionable benefits. Thanks to the PLC we can enjoy the internet on the same PC with all VUSC4WIN features. Online access to the rain scatter radars map, ON4KST chat and more applications on each workstation which is beyond price. The internet interface was provided by the OK1XNG's router and it was shared in the network by the PLC. We had this stuff in the cabin because of 2m so there wasn't any QRM for the local 450MHz installation of CDMA.

Yep and even one feature is remarkable: we had new cast-iron grill. Thanks Majka OK1DYX for so good steaks, really cool!

The contest is ending. Last 70cm contact to the ON and it's over. Weather was fine, OK1TEH made our the best result in our history on 23cm (despite the smaller power), 2m was just a band for fun and all guys were happy to run the contest as they wanted to, OK1ZAD is smiling above the 13cm equipment. Some are leaving and we're going to near Ota's pub. But before it our final group photo.



Is there anything more to be said?

Cu in the next contest!

73! de: 

OK1TEH, OK1DIX, OK1VPZ,  OK1DYX, OK1ZAD, OK1JFR, OK1RK, OK1KN, OK1XNG, OK1BAF and also from Pepa, who was smiling on our all work forbearingly
