Scott,

IMHO, changing from a BNC to a UHF jack (SO239) would be a step backwards. The SO239 requires that the connector be tight to produce a reliable connection, BNC and type N connectors do not.

If the BNC connector on the K2 has been abused, it can lose contact at the center pin, so you may have a valid point, but replacing it with a new BNC connector should solve the problem - if yo want to get really fancy, replace it with a type N connector.

Hello

Has anyone had any trouble with the bnc antenna connector on a K2?
Mine doesn't make contact with the antenna coax all the time. I can tell
by the receiver noise when it looses contact. I think it is probably doing
that when I am transmitting, but I have no way to tell except the swr goes
out is sight. I have tried several of the bnc to pl239 adaptors and have the
same problem with all of them.
Has anyone ever changed out the antenna receptical from the bnc to a
so239?  This loosing contact with the antenna while I am transmitting can't
be very good on the K2 final amps.
Any info will be appreciated.
