Hi Stefan;
Sorry, I does not TX on 137/472. But at Argentina LU1DOW does :D.
I have only RX capabilities as Alejandro LU8YD have.
Here I use a 4.5m high mini whip + SDR IQ. Will have a second mini whip (7m)
in some months. Actually I receive 171, 252 BCs, 391 DDP Porto Rico, 274 SAL
(detected), USA & Caribean NAVTEX etc.
May be those QRSS 30/60 can be detected as well (suspect of my freq accuracy
capabilities).

Hi Marcus,
Congrats to that success! Since when are you QRV on LF? Can you describe
your TX station?

Alejandro;
Thanks for invited me to took part on such test;
I sent a msg before but I think attached pix (300k) was too big for the
server rules (I don't remember the limit).
So there is a bit more compressed pix of LU1DOW signal at 1600Km north
(GG66rf, S Paulo area)
