I had ads-b exchange working on my linux mint but now is broke!

Not sure what happened but I am no longer displaying from my antenna although all services are running. This happened after I did a re-install after I changed rtl-sdr dongle due to flakey antenna connection. Thought it would work better with different dongle. Status of ads-b feed on feeder page shows connected and mlat shows connected. Checked following services and all active running:

systemctl status tar1090.service
systemctl status tar1090-978.service
systemctl status adsbexchange-stats.service
systemctl status adsbexchange-feed.service
 systemctl status adsbexchange-mlat.service
systemctl status readsb.service

Thanks for the help in advance!
