Receiving FT-8 stations.

Nothing about this, however, in your config.toml you MUST specify audio_sps=12000 because if you don't it will NOT decode.

Other problem is ofhen that the system-clock of your PC isn't running correctly.

Simple and fast way to correct this is to install chrony.

apt install chrony
Edit chrony: nano /etc/chrony/chrony.conf

Make sure it look like this:

pool ntp.ubuntu.com
pool pool.ntp.org

rtcsync
makestep 1 3

# leapsectz right/UTC ----- YES this one must be disabled!

All the rest isn't that important, can be best left default.

Now restart: systemctl restart chrony

Then run: chronyc sources (wait until you see the servers show (37)7 - beware can take 10 minutes!)

When they do run: chronyc tracking

Then it should show the correct time and date, within less then 1msec, normally.

Chrony will keep your system on time every x minutes....automatically, never look back ;D

FT-8 is a precise-time-protocol, so wrong time means no decoding.

Typical test 7074KHz USB then click FT-8 and after 30 seconds or so it should show stations.
