Hi,
I have acquired a second-hand K3/100 with the Auto ATU and 2nd receiver, which I have been checking out, calibrating and installing extra filters. Everything has worked exactly as expected, until I tried to use an antenna connected to ANT2 socket. I have a fan dipole connected to ANT1, and a 50 Ohm dummy load to ANT2. When I press the ANT button with the AUTO ATU in Bypass, there's a click, and the annunciation changes from ANT1 to ANT2, but I can still hear signals just as loud, even though there a dummy load on ANT2. Also If I transmit, it doesn't matter whether I have ANT1 or ANT2 selected, RF always comes out of ANT1 socket. If I have the ATU activated, the symptoms are exactly the same, except when I switch from ANT1 to ANT2 there's no click. The Auto ATU works fine, and I have the KRX3 "ANT=bnc" set. I can also hear stations on the 2nd receiver through the ANT1 socket or via AUX antenna socket. The firmware has been updated to the latest versions for MCU, FPF, and both DSP units. Any help would be most welcome. 73 de Tim G4ARI ______________________________________________________________ Elecraft mailing list Home: http://mailman.qth.net/mailman/listinfo/elecraft Help: http://mailman.qth.net/mmfaq.htm Post: mailto:Elecraft@mailman.qth.net This list hosted by: http://www.qsl.net Please help support this email list: http://www.qsl.net/donate.html Message delivered to arch...@mail-archive.com
