Topband: BCB interference ?

[Stan Stockton]

Why can't you come out of Ant out jack through filter and back in through ant in jack and select RX antenna?

I finally had to build a 7 pole HPF from W3NQN's article many years ago. The catch is it has to be able to handle the transmit power too. There is no room in the K3 for a receive filter. Elecraft just blew me off when I told them about the problem. They said I was 1 in a 1000 that had that problem and they were not going to fix it.
