Dear Gerhard, LF Group,There is an NDB "BRK" listed near Vienna on 408kHz, which is 3 x 136kHz. Allowing for +/- a little frequency for the AM sidebands this could be what you are hearing - the active whip would pick this up, but a tuned TX antenna would attenuate it considerably. Perhaps a bit more preselection required? Cheers, Jim Moritz 73 de M0BMU----- Original Message ----- From: "Gerhard Hickl" <[email protected]> I'm working on a new DC-CW receiver and while testing, I found a CW-Signal on 137.00 sending "BRK" every 10 seconds. |
