And - do not underestimate the ability of your brain to act as a CW "filter".
When I was doing EME on six meters (using CW) - I found using SSB bandwidths made it easier to copy the weak signal. You can hear a few recordings of EME signals with SSB bandwidths here: http://www.kkn.net/n6tr/sixeme.html 73 Tree N6TR On Fri, Aug 7, 2015 at 5:58 AM, Tom W8JI <w...@w8ji.com> wrote: > I'd like to know whether it's ever been established that some very talented >> hams can out-hear the best SDRs and/or DSP available.
