EnsembleTRX PTT switching and RX circuit
OK this caused me a few headaches as one BS170 was duff and so the PTT from the AVR USB was not functioning.
So I replaced the Q10 BS170 and it is now functioning fine. Lesson in there for anyone building one... watch the BS170!
Now to place the RX OP amps (actually just one IC but dual OP amps) already placed the RX mixer FST3253.
That is the RX side complete.
Now to test it.
