I completely understand and respect your statement. A few month ago, QRSS60 or anything slower was out of my imagination but meanwhile I'm happy if a sign of my signal is seen at much lower speeds. No doubt, those extremely slows modes are not useful for a QSO, they just give us an idea about propagation and other relevant issues. I would like to compare it with the following: I have a daughter, 13 years old and she is sometimes watching me with my radio-stuff.....I once tried to QSO on LF in CW with some guys here in Austria....not more than 300km away and when I finished, she asked me what the hell this all was about. I said that I made a contact with others by radio but she just said: "Hey dad, ever heard about cell-phones???" I had a hard time to explain! 73 OE3GHB Gerhard Am Dienstag, den 08.03.2011, 20:08 +0000 schrieb mal hamilton: > Gerhard > In that case I will not bother with 9 kcs.
