Dan,
The K2 BNC jack will have a DC path to ground whether the K160RX is
installed or not. It is not "ground" for RF, but will show a low DC
path to ground if you measure it with your DMM. If you disconnect lead
3 or 4 of T4, the DC short to ground will go away.

Need a bit of help here-I’ve installed the 160 receive module on my venerable
K2 #1010 which I built back in 2000..for some reason I seemed to have created a
short across the main antenna jack (J4) with this installation. In testing
after Installation the reciever was totally deaf as was TX, and I found that
there’s a short somewhere between the center pin and the outer sleeve of J4,the
main BNC jack first the radio. I inspected the jack just in case,but appears
okay. I’m suspecting some sort of short around J14,the 16 pin jack for the
adapter. When installed,the radio functions normally and the module is
recognized in the menu. Just zip on recieve and transmit. Inspection of the 16
pin socket didn’t reveal anything obvious under a magnifier. The radio was in
daily use up to a few days before. I checked the obvious things ,or so I
thought!
