I believe this is a question specifically for Hans :)

Having recently had the receiver mux chips be destroyed seemingly without any other failure of the switching circuit controlled by Q508, I'm wondering if there is a potential race condition such that the transmitter "switch on" code may be reachable without the receive switch pin on the microcontroller being pulled low.
?
I assume that transmit is almost certainly gated behind a command changing that pin state, but I'm wondering if there's a machine code level race condition that would let the transmitter operate without that pin being guaranteed pulled low?
?
Just a thought, as this seems like a strange failure mode.
