FT8 question

[Jr]

Happy Holidays All!

I'm using FT8 into my KX3 in Data A mode but getting almost no contacts, On
the waterfall, I see a lot activity on 40m and 20m. I've followed the
advice from the KX3 manual for levels, but I still get very few
connections, like I'm not being heard. I also run k1jt WSPR mode and that
seems to work well, I get consistent results on the bands that are open.

Currently I have the KX3 set to 10w output into a 23' long endfed dipole
20' in the air. I live in an RV Park which has very very restricted antenna
restrictions! One complaint from a neighbor about any RFI would cause the
manager to tell me to take the antenna down.

A couple of years ago I ran FT8 on my ICOM 746pro at 5 to 10 watts max
output and had very good results.

So, my question am I doing something wrong? Any suggestions would be
appreciated?

tnx and 73

What are you doing to sync your computer's clock?  Do you decode
signals?  Look at the DT values -- they should be between -0.4 and +0.4
sec. Do you have the latest WSJT-X software?  Changes to the FT8
protocol were made a year or so ago, and the old software no longer
works for FT8. The current version is 2.1.2

Are you sure that Windoze audio is set correctly for the sound input and
output device you're using? Windoze tends to trash audio setups when it
does updates.

Also note if you have a lot of other things running your CPU utilization
may get too high to do decoding. I find that Chrome browser will shut down
decoding until it is closed and decoding promptly then resumes.

Use the Task manager to watch a few cycles and sort on CPU utilization to
see what the big contributors are.
