A serious appeal to all the CW and QRS(S) ops on this reflector. I'm interested in what can really be achieved in terms of readability of weak CW . For the calculations mentioned earlier I made
Hello Andy, This is an interesting question. The last few years I have increased the readibility of very weak non directional beacons by decreasing the filter bandwidth. The results have been quite s
Good.... Confirms exactly what I assumed. 5dB in 24Hz (which is about the same effective bandwidth of a good pair of ears) is -15dB S/N in 2500Hz Its interesting, too, that SSB is readable at fa
