K3 RX dead 80/20 meters

kennedyjp
Hello all, I need some help ! My K3 s/n 3378 has gone deaf on 80 and 20 meters, all other bands are good. It does not have a second receiver installed. I have confirmed the receive signal on the other bands is good with my HP 8640B signal generator. I can get a signal thru it on 80/20 meters but it takes a ton of RF from the signal generator. The attenuator is not on nor the preamp. The internal antenna tuner works as expected. I have normal power out on all bands including 80/20 meters measured with a Bird 43 and Bird dummy load. Any help would be much appreciated.
