Allison. Thank you. That is a good tip.
I will introduce that resister once I have it working.

One further issue is to insure the wire from the base of
Q10 on the ubitx to the AGC board is very short!  It
has RF on it and a long wire will impact stability
and possibly introduce noises.

Better way to attach to base of Q10 is through a small resistor
of 100 ohms to reduce the amount of RF on the wire.
