Problem solved:

Thanks Chris Mark Alan + Nitin.

FYI.   Although there wasn't another program running, it looks like SDR#  had set the parameters for the gain and filtering. - I'll have to watch out for that.

Running SDR# again, I reset the front end filtering to '2m'  and saw that copied across to FoxTelem.
So monitoring back in action.

Thanks for the help, and good luck with Fox-1D

Hello David!

 From time to time with the FCDPP I find this helpful to do if something is going "wrong":

exit FoxTLM
unplug/plug in FCDPP 
followed by launching FCHID2.002.exe then resetting to default values, then setting the frequency to the "center" frequency I want to use with FoxTLM
followed by launching FoxTLM

That fixes about anything "weird" I've seen!  Give that a go.
