3khz??? The whole spot is only 3khz. Try 3hz. Aug AG5AT Sent from my iPad > On Aug 29, 2021, at 3:00 PM, Koen Bijl via wsjt-devel > wrote: > >  > Popularity from ft8 is that all the hams are within 3 kHz and not separated > by let’s say 20 kHz. > > > Op zo 29 aug. 2021 om 21:35 sc

Gordon,It's Phil's proposal, not mine.I merely pointed out that network throughput (a.k.a. the number of simultaneous users) would be affected negatively if only 50 channels (Phil's original proposal) were available, a problem that could be ameliorated by channel overlapping and two-pass decodin

Popularity from ft8 is that all the hams are within 3 kHz and not separated by let’s say 20 kHz. Op zo 29 aug. 2021 om 21:35 schreef Gordon Weast via wsjt-devel < wsjt-devel@lists.sourceforge.net> > Ed, > > When I look at decodes on 20m today, I've seen multiple times when > signals offset by as

Ed, When I look at decodes on 20m today, I've seen multiple times when signals offset by as little as 1 Hz are decoded just fine. Basically, the protocol works fine with lots of overlap.  There is NO need to channelize transmission frequencies. Restricting transmissions to the channels you're
