No problems running Foxtelem with both the Foxes and HuskySat-1 using a FUNcube dongle on WIN10. It switches the center frequency as it should. It calculates that based on the satellite(s) so that the center spike is always away from the RX frequency. For instance, when HuskySat-1 is up it uses 435.825 MHz. If you are using the "Foxtelem Calculates Doppler," highly recommended, you will probably need to use a different downlink frequency for good tracking. I use 435.8034 MHz. The spacecraft frequency is very precise, the FCDP+ not so much.
