The first secret to PSK reception is to turn off the AGC. And, if you can find a way to use your filters, that will not hurt, either. Noise blankers also greatly limit your dynamic range, though I find DSP filters often help the reception. I am not aware of too many receivers that can handle an extremely strong signal 60 or 100 Hz. away from a very weak one, regardless of the filters in play, or the modes involved. The '31' in PSK31 refers to both the bandwidth and the baud rate of the mode. 31 is slow and narrow. 64 is faster and less narrow. 256 is wider yet, and but MUCH faster. Now, if you park your KW 2 Khz. away from me, I won't care that much. With the AGC off and the DSP filters on, my IC-7000 won't know you're there. It isn't socialism, it's civilization. You can't poop on the public commons, either. If you want to run a KW, go up the band a little and run RTTY. I run high power on RTTY, when I don't care about my power bill. Thanks to AG3Y - I was thinking about FLARQ in my previous post - couldn't remember the name or the guy who created it. I hope it catches on - I really miss AMTOR!
