Hi Evan
Thanks for your response.
No, I did not use the method you suggested but will try it soon. That may be the answer.
I do not notice any difference in the rf level in the receiver with the antenna connected or disconnected.
The rf level is very low. I can transmit with the Ubitx just fine.
I hear a few birdies across the spectrum and they can be quite loud with the volume turned up.
I have continuity from the coax center connector to TP1 which passes thru the low-pass filter.
If I transmit with another transmitter with one or 2 watts I can hear it loudly on the Ubitx receiver.
It makes no sense to me, but I will do the BFO calibration as you suggested. I will let you know the
outcome when I'm done.
Thanks Evan
Doug
