[Elecraft] K3 RX antenne not working on TB

[Dick Grolleman]

Hello All

Just discovered a strange thing last night. As I switched from 80 CW, to 160m using the same RX antenna, there was no receiption on TB. If I switch from TX antenna 1 to 2, and hit RX antenna it is working. Why is the RX antenna only working when antenna 2 selected? This happens only on 160m, 80 m is fine when antenna 1 selected. I have been using the rig for over 2 years now nver had the problem before.
serial number #1168
using FW 3.63 for a long time, so that did not change it either.
