Here is something else to try. This assumes that the PA pre-filter has
been tuned to your frequency. With the TX filter bypassed, but everything
else hooked up, try turning the power set control down a little. It may
be that you are simply driving the PA too hard and it is shutting down.

simply filtering all of 447.000 to handle the isolation of the transmit
