>A fade of 6 to 10 dB us not all that uncommon on HF. >So all you are doing is compensating for the fade. >Walt/K5YFW A PSK125 signal can be decoded at 3 dB S/N, it will not be decoded at 2 dB S/N. On 30m we see fades of 80 dB. Any dB you can add on the TX side is gain, it can make the difference between 100% copy and lousy copy. 73, Rein EA/PA0R/P -via pskmail-
