[Elecraft] FW: KRX3 MAIN input

[R. Dean Straw]

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.

Hi,

I've just installed my KRX3. 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?
