My backup analogue BFD receiver seems to have stopped receiving.
I have two complete systems and both transmitters, all cables and motors work fine. I have tried switching every other part and narrowed it down to the receiver unit, however, the broken system calibrates fine and also works when hardwired
I have tried all channels and none get any response. There is just an occasional motor “twitch” when switching to and from the channel selected on the the RX unit.
Any ideas? I’m in the UK near London so also looking for who is best to got to for service.
