[amsat-bb] Fox Tlm with FC dongle

[David G0MRF]

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
