KX2/AX1 WSPR vs FT8

MaverickNH
I'm running my KX2 on 5W with a AX1 vertical loaded whip on 20m with two
counterpoise cut for 1/4 wave. I'm able to RX/TX WSPR with my spots heard in
minus single digits - some positive single digits. I'm also able to RX FT8
but unable to QSO - nobody apparently hears me on HamSpots.

It seems I have my answer but was hoping that if I could get my signal
spotted on WSPR I should get *some* spots on FT8. Perhaps FT8 has gone well
out of low power and I'm in the weeds. That and I'm using vertical
polarization with most horizontal. I'll add I'm operating inside hotel rooms
while traveling but I figured walls stop WSPR and FT8 equivalently, but the
2min vs 15sec cycle times come into play as well.

What are you using to set time.

Bret/N4SRN,
I am running a KX3 indoors into a mag loop for 40-30-20 and I get plenty of
wspr spots on my signal at 1 watt or less, and can hear others too.
FT8 needs more signal though, the packets are 1/8 as long (15 seconds
compared to wspr 2 minutes) and is still trying to push similar amounts of
data in a much shorter amount of time. So it is a lot more of a challenge
to make a two way contact. If you are being heard in single minus digits
that is pretty good, my signal is usually in the twenties. I think I made
like one or two FT8 contacts when I first tried out WSJT-x, but lately my
attempts to make an ft8 contact have been unsuccessful. I would say just
keep trying, and eventually you'll make ft8 contacts. I mostly stay with 40
meters though, seems to be the best overall band these days for me. I am
looking forward to the 40 meter add-on for the AX1!
73's, Mike AB7RU / Spokane WA
