Hi all.
I've returned from a break over Christmas and noticed the signal level on my fox-tlm screen has dropped. I've also noticed that the various parameters for the dongle include LNA and Mixer gain along with IF bandwidth of 200kHz However, there is also a box that says RF filter and that is set to 0-4MHz.
I can't see anyway to change the RF filter setting ! I assume this should be 2m to select the internal SAW filter. Any idea where I can start looking?
Many thanks

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.

If all of the parameters are greyed out, including LNA and Mixer Gain, then something else has opened the connection to the Dongle and FoxTelem can't read the parameters or set them. FoxTelem will still read the audio from the dongle because it is a different interface. This allows you to have multiple programs all reading from the same dongle, but only one can open the connection and control it.
If LNA/Mixer gain are not greyed out and the filter is set to an odd value, then something in the dongle has gone funny, as Mark said. Un-plug and re-plug should be enough, but his more extensive procedure should surely work.

Hello Nitin,
I use 145930 for center frequency in FoxTLM.
