"The KAT Utility Operate Tab follows the last RF Tx frequency. It does not follow the rig freq. But does not follow when Tx'ing on 40 or 160."
It seem rather unlikely to me that RF detection would fail in both the KAT500 and KPA500 and that both would fail only on the same two bands. It seems more probable that neither is receiving a satisfactory RF signal on 160 m and 40 m. I think what I would do is try to test the KAT500 and KPA500 separately: Test 1 - Rig > KAT500>50 ohm dummy load. Does the KAT500 track RF freq? Test 2 - Rig>KPA500>50 ohm dummy load. Does the KPA500 band track RF frequency? If neither track 160 and 40 but do track other bands then I would look at the RF signal to check its frequency, amplitude, and spectral purity. A dummy load, RF sampler, and spectrum analyser would make this easy but I don't know what equipment you have available. Is it possible that you have the rig in a cross band split configuration and you are not actually transmitting on 160 and 40? 73, Andy, k3wyc ______________________________________________________________ Elecraft mailing list Home: http://mailman.qth.net/mailman/listinfo/elecraft Help: http://mailman.qth.net/mmfaq.htm Post: mailto:[email protected] This list hosted by: http://www.qsl.net Please help support this email list: http://www.qsl.net/donate.html
