Dear Frank: I just finished installing my KRX3 and had exactly the same problem. I traced it to a poor solder connection on the small PCB called the SUBIN module.
The "3-dB Splitter" transformer T1 lead number 1 was not soldered properly to terminal 1 on the PCB. This meant that the MAIN input was not getting through. Simply re-soldering the connection brought operation to normal. 73, Dean Straw, N6BV You said: Message: 15 Date: Wed, 24 Dec 2008 15:18:33 +0100 From: "Frank R.

All went okay. Although I do have a KAT3 installed, I chose the subreceiver's alternative antenna to be the BNC one. If I've understood correctly, pressing BSET followed by ANT allowes me to switch the subreceiver's input between the main receiver's antenna and the BNC antenna. But, irrespective of whether I've selected MAIN or AUX, the subreceiver always uses the AUX antenna. Any clues as to what could be wrong? 73, Frank PA4N Dean Straw, N6BV n...@arrl.net _______________________________________________ Elecraft mailing list Post to: Elecraft@mailman.qth.net You must be a subscriber to post to the list.
