BC-654 Receiver

[K1RMC]

My first post. Thanks for the add.

I recently picked up a BC-654. I am currently working on the receiver. I’m running it on a 60 volt power supply and a D cell. It receives 75m AM fine.

However, it has a couple of issues:

1. Typically a 3PDT switch is used to turn off the AVC and turn on the BFO when the receiver is separated from the transmitter. What pins on the 12 pin terminal do I connect to make that happen?

2. What is the BFO bias voltage?

3. My receiver only tunes 3.8 to 5 MHz.

4. Even after I peak the receiver, i can only copy signals for only 200 kHz.

Thanks for any assistance on this.
