Folks on FT-8 use a 2.5 khz ssb wide RX filter.FT-8 is supposed to be
good for 20 db below the noise floor.
I assume that means 20 db below the noise floor of the 2.5 khz RX filter ?
But a 250 hz cw filter would drop the noise floor by 10 db... vs the 2.5 khz
wider filter... if CW mode
Give FT8 a try. I worked my first EU the other night and then a few
last night in the contest, G, F, EA and CT9. Not much Caribbean or
Africa on. I did copy a couple of JA's the other night while the
antenna was at EU while I slept.
Remote is where many of us will be as we continue to fill
Hi Jim,
Well, yes on the 5 acres, but still suburban. But, I do notice that FT8
on the vertical 160 T often decodes as well as my DXE 4 sq receive which
has directivity and thus less noise. Same comment from another op here
locally. I don't see any advantage to subsegment filtering, and in
nope, my lot is 120' x 160'...1/2 acre in suburbia...and like you, different
flavors of noise in different directions...
I DO find FT-8 hears about 10 db better than i can on cw...FWIW...

Don't let noise stop you from transmitting.
