QSL Routes

QSLs for QSOs with us are via DF2ZC, address as in qrz.com

We prefer direct QSLing, via Club it might take >>  one year.

Please enclose 3 US-$ for postage and handling, as well as a return envelope or an address sticker. PLEASE NO IRCs...we do not get them exchanged for postage!

You can however make things easier by just sending us 3 US-$ via paypal to our donations account (see right at top) with call sign and QSO data in remarks. You do not need to send a QSL by post then.

Sponsors will receive their QSL automatically as soon as the cards are available.

What a change now working with a preamp again! Now it was finally fun sitting in the BBQ shelter and freezing (last night was rather cold and windy) and working one station after the other, now with decent signals strengths. Thomas DL1VPL with his single 12 elements and 750 watts out peaked at -22 here, amazing. Conds were twisted most times: We called hpol and received vpol or vice versa.

Every day when the moon was above us the conds changed and we did not copy much anymore. Therefore around midnight we decided to go for a short sleep and return at 4Z for US west coast and Oceania moon rise. We copied Ed KL7UW very well for half an hour but due to his noise situation he couldn't copy us long enough for a QSO: so sad. NH6Y was easily worked as soon as he had copy from us. W2DBL and KG7P were also copied but not completed. At these low elevations the noise rapidly increased so no further stations could be seen in the FFT display. That is particularly disappointing as we knew FK8CP and ZL3NW were anxiously awaiting their moon rise and their small chance to work us. After 0525Z the moon was the blocked by the neighbour'shouse...so that was it for this pass.

Next moon rise is 1845Z today 29th. We will work until local midnight and the break down the station because we leave home tomorrow morning. CR2EME is tx 1st on 144,114 MHz and rx +/-500 Hz.

Please use W7GJ aka Lance procedure when calling us. It helps to avoid time sending OOO to stations that call us but do not copy us. And of course you should only call with OOO when you do copy us or clearly have our sync in the FFT display. Lance procedure is explained here or at the right side at 

"How To Maximize Chances Working Us".

Some clarifications about the W7GJ Procedure:
- Call us with OOO only when you have copy or clearly see our sync.
- If you do not see our sync anymore you must go back to calling with both call signs only.

By this method we can see who has copy at the moment and who maybe has just lost copy. And we do not waste time calling a station that does not currently see us. Some stations have very well used this method (DL1VPL for example) and by that incresed their chance of a QSO.

We are very happy with the 70 cm results given we had only 2 x 17 ele DK7ZB yagis and some 150-200 watts out. Most of the time however the polarisation received was orthogonal to our hpol antennas: We were well copied but saw an empty FFT display only. At one point we decided that one of us - DH7FB lost the draw - had to act as human switch for hpol/vpol. In the 10 seconds between tx stop and rx start he manually turned one of the yagis to vpol and vice versa at the end of the rx period. Sigs popped out of the noise then! With this method we worked at least 2/3 of all our QSOs  though we had some 3 dB less rx as the other yagi remained in hpol then. Sadly, the 10 seconds were too short to turn both yagis. We will find a solution for this for our next activity.

Some words about the amp we used: We were always looking for a small sspa giving some 200 - 300 watts out on 70 cm. Apparently there was nothing on the market. Luckily Zdenek OK1DFC approached us offering to build a sspa of that kind for us. And so he did. It is a very professional looking small amp (still naked without box, we had no time before departure to build a case) and delivering 250 watts max, also having an LNA integrated. It was placed directly below the antenna (luckily no rain on Azores). For next time we will replace the input attenuator for a smaller one so that we can drive the amp to full output. Zdenek himself hat to travel to the UK for his job which came at short notice. Too bad he could not work us but luckily he had worked Azores before. So at least he did not miss out. Anyway, without his ham spirit all those 70 cm QSOs would not have been possible. Thank you, Zdenek!

The big CW signal from DL9KR was amazing. It peaked 559 (on the single vpol yagi). Upon return home we will upload it here or to our dedicated web site.



Next moon rise is 1740Z today 28th. We will work again on 2 m. CR2EME is tx 1st on 144,114 MHz and rx +/-500 Hz. We managed to repair one of the LNAs. Hopefully it will stand the stress...

LNA repaired

Update: 
We have once more checked the relays of the LNA and once more tried to clean them with a piece of paper. Now it looks like it is working again permanently, no outages anymore. So next moon pass on 2 m (28 and/or 29) we should be fully QRV with LNA - and hopefully start having fun.

Next moon rise is 1630Z today 27th. We will work 70 cm only, frequency is 432,087 MHz and CR2EME tx 1st. 

As you all know by now we have trouble with our preamps. One apparently got damaged at travel and the other one has a relay issue: Sometimes it connects sometimes it doesn't. We have opened it and carefully cleaned the relay contacts with a piece of paper but still it does not reliably connect through. When ist does it is fine. When it does not we copy nothing at all. The latter can last for quite a while. So we decided to continue without preamp. From our experience from previous DXpeditions this means we hear some 6 dB less than usual. Most signals (if we copy any) are between -25 and -31 so this is no fun at all. It is almost like in a VHF contest in the middle of night: You are calling and calling and hardly anyone answers. No, it is worse as we know there are many many callers outside which loose their patience. Often we get complaints on N0UK such as "I'm calling you for hours now". Well, what should we do? If we do not copy this particular caller we can't send a report. Whether or not that person is complaining about it in public - it doesn't help if we do not see his signal. However, the alternative would have been to stop everything and go on tourist activities instead. Hence, we are very proud that we are already approaching QSO no. 100 on 2 m. And yes, both preamps worked fine before we left home.
