yesterday I was on the "Ham radio" for the first time and probably the last time!

For me, the show was a little disappointing when you know big fairs like the "Aero" in Friedrichshafen, where I was this year also. The only interesting topics for me were the stand-alone full functionell 5W-SDR-TRX FDM DUO from Italy, with which one I could play, and a SDR-TRX-series from Russia, I did not know. The big 125W-SDR-TRX SunSDR-MB1 (160m to 2m - max 80MHz Panadapter) even has touch-screen (http://www.sunsdr.com/en/home.html). The transceiver makes a very good impression, but unfortunately for my wallet a little too cheap (3700 EUR).

End "Off topic"!
The low-loss coax cable I did not get as much as some other things for other antenna projects. So I must now order coax cable.
OK, I'll start with 11 turns in the stub and test approach me. Thank you for your reply and the good idea, Psi.
Also, now a bit more work coming back into my job to me. So my new building of the gain master can take a little. But then I will report!
Regards,
Andi
