Hi all, I just finished QSO on 136,5 kHz in CW with Reino/OH1TN. ok, thatīs not exciting. but this is: the distance of 1175 km has been managed with the 10 W HF predriver of my new (incomplete) trx.
I also have received a signal, which could have been that of Jim, but I was using an untuned string of wire (not even 'wet'...), so cannot be sure. But I noticed that the QRG was 135.925 and not 135.

Hi Andy, the 7fsk is a fine code. once decoded one can read it without the help of a screengrid. I read ur 400W signal. see attachment. the 5W signal could be seen here, but no chance reading it. if
