Current news to the station, operation and maintenance, etc.


The T/R-switch for the SDR, RSPduo, goes into practical use. This enables me to operate the SDR, the Icom IC-7400 and the OM2000plus, on only one antenna! Even at a transmitting power of more than 1000 watts, the transmitting signal at the antenna input of the RSPduo is at a maximum of 65 dbµV or better −42 dBm !!!


Since May 6th, 2021, I ONLY use the cloud platform, HAMLOG, for the eQSL exchange. I will not use any other platforms! Please don't ask!


Since 2 nights, again very strong aurora, here at the location. An impressive spectacle! Duration around 1 hour each! More pictures in the rubric "Location"

After many attempts and numerous tests, I unfortunately have to find out today that radio operation via QO100 from my location is not possible with the transmission power available to me. I am therefore ending the QO100 uplink project. If you are interested in a Kuhne MKU UPConverter 2424B. Please send me an email. Invoice available and warranty 2 years (11/2022)! SOLD!



The first stage is done ... From today on reception via QO-100 satellites with a 90cm SAT dish from Kathrein and a modified universal quad LNB from DJ4ZZ. I'm curious to see how the LNB will perform in the extreme temperatures.

Since today first tests with the new RSPduo on shortwave...

Due to the bad weather conditions, with heavy rain, I finally have time today to optimize the double bazooka antenna (DBZ40). The DBZ40 is now attached directly to the antenna mast (BP60), about 16 meters above the ground and now runs westwards to an auxiliary mast (5 meters). After the first tests, the efficiency and the radiation diagram have noticeably improved, which can be seen in the availability when calling DX stations. It remains to be seen whether there has also been an improvement in radio traffic in the direction of DL. I really hope so! So we are waiting for better conditions for further tests.

Until then, GDX!

Current pictures will follow in the section Radiostation - Double Bazooka !!!



The annual maintenance work is again in the period from 05. - July 12th, 2020 on the antenna system and the Versatower BP60.


Something on our own account... The current costs for QSL cards and their dispatch via Bureau 1000 pieces currently amount to approx. 100€! In addition, there are various costs for DX stations and their QSL cards and postage of around 150 USD for shipping per year! For all this QSO's I will no send a QSL cards for digital modes as FT4, FT8, PSKxx, DSSTV, etc., only for RTTY, CW and SSB QSOs , send I my qsl card to EU stations. I confirm only all these QSOs via the LoTW. Only DX stations and SWLs will continue to receive their QSL cards via the bureau or directly! Please read all the details on my start page!
Please understand!

I often get the question ... Is it worth uploading to the LoTW? Yes, I I'm thrilled. As of 05/2020, QSO's since 2009 in LoTW 76%! The return on paper QSL cards is around 42%! I hope to have answered all the questions..
