Hi Joe,

That's nice!!!

OK, i will QSY to 136.500 kHz and will run a CW beacon there, as soon as=20
my current call transmission is finished. Hope this QRG is OK for you? I=20
will also listen from time to time on that QRG.

Any reports, also from others, apprechiated.

Please tell me when it is OK for you about the test. I'm waiting for=20
your answer.

PS: What about the questions below? ;-)
