Find someone with good eyes or one of those clamp-on-the-desk
work lights that has a 4" diameter magnifying glasses that is
mounted inside a circular florescent tube.
Then closely inspect the connection between the center pin of
the BNC and the PC board. I'll bet you that it's broken and
making intermittent contact. Get in there with a fine soldering
tip and remove the broken jumper wire and excess solder then
make up a jumper using tiny braid - I use the really fine
solder-wick. I put a blob of solder in the BNC pin and on the
PC board and then QUICKLY tap the braid into each blob.
The intent is to have the solder-wick braid be a flexible
connection allowing the BNC center pin to move a little as
you insert and remove the antenna.
