JI'm posting just in case someone else has this problem.

I added more bonding to my station and put a lug under the IF In 
BNC connector on the P3 as part of the project. Afterwards, my 
P3 was noticeably deaf. When I started to operate in the North 
American QSO party, I couldn't see any of the stations.

I got out the manual and discovered that there was a switch to 
activate the IF Out connector. I moved the switch to Off and 
everything was good again. I moved it to on, and I only lost 
about 3dB, just like the manual said. Some experimentation 
showed that if the switch was between off and on, the loss was 
much greater, like 15dB or so. I must of pushed the switch when 
I was adding the lug.
