Pete - I'll give that a try and let you know.? I also got another rare/unusual bird coming, an HE-43C.? I've never seen a CB where you transmit with crystal and receive by VFO.? What I plan doing is to put in a circuit that replaces the crystals with an Arduino controlled 5351 module.

I didn't recognize your name in my initial response. I indicated I just finished a manual for a HE-43C. When I was putting the mailing label on the envelope, I realized it was for you. So it's on the way. Ah; the perils of aging.

Lafayette HE-43C is not rare. It is identical to the HE-20C (which we sold 1000's of these sets - HE-20, 20A, 20B, 20C(relay and electronic switching versions), 43C) except the 43C works on 110V AC and 6 volts DC. The 20C works on 110V AC and 12 volts DC. Other then that, they are identical. I just finished a HE-43C manual for a customer. Both the HE-20C and 43C were made by United Scientific Laboratories (USL) in Long Island City, NY.

A tunable receive and a crystal controlled transmitter was quite common with a number of manufacturers in the early 60's. A Spot switch obviously was common on these transceivers.
