[Elecraft] P3 Loss of signal

[George Danner]

Bill,
Another issue with BNC connectors to take into account is that 50 ohm & 75 
ohm BNC male connectors have a very slightly different diameter on the male 
center pin. The larger one (don't remember which one) can expand the female 
center socket. If you switch to the smaller version male after using the 
larger one, you may get an intermittent connection. You can tighten the 
female with a dental pick.
We mixed connectors when TV stations switched from UHF to BNC for video. We 
found this issue years later! All BNC males are not the same. I make sure to 
use 50 ohm BNC connectors in the ham station for this reason.

Hi Don,
Thanks for the reply. Yes that crossed my mind but the cable I use now was
suppose to be from the "new" batch. I called and got replacement from
Elecraft Parts after earlier problem. I think this cable has been in use for
better than a year or more and nothing has changed. I will switch cables as
soon as I can find or make a new one. I was just curious if anyone else had
a similar problem crop up.
Thanks again,
Bill - W0BBI
