Hi Dick,
Is your hardware/software control working?
Is the CAT interface known to work?
When tracking the satellite-does it show "C+" in the top right window
of setting options? It must have the "+" or it won't adjust the radio.
You can set it to "+" by default by checking the Setup/Options CAT
Control setting.
If the above works, but it's "drifting" out of lock--your Keps may be bad! If
you are tracking, but it seems "off" I'd check your PC clock and the Keps you
are using. The ones currently available via Celestrak seem to work fine.
Just make sure you're using them :)
Last night and this AM my station printed and sent over 100 frames, fully
automated while I was away. That means the Keps are getting quite good.
73,
