[Elecraft] Second RX and KBPF3

[aa3cs at me.com]

Milt,
First make sure you enabled the correct KBPF3. You may have actually tried to enable one on the main RF board and not the sub RX. if you have the right int turned on then take it apart and make sure it is plugged in properly. The shift register is how command data is transferred from the MCU to the various parts of the radio. If that still doesn't work, try installing the module on the main board to verify that it is, indeed, ok. If none of that works it may be time to call Elecraft support.

73 and good luck,
Chuck - AA3CS
