Evan, it seems the lost signal on receive after a FT8 transmission is from a stuck LPF relay for 20 meters. When I switch to another band using another LPF relay and then switch back to 20M (hearing the relays clicking) I get the proper signals on receive on 20M back again. I wonder whether this problem is frequent and whether it was part of the reason to change to MOSFETs for LPF switching in the sBitx V2. Short of replacing the relay, do you think there¡¯s a good way to solve this problem?
