About the Company

Treetop Circuits has been owned and operated since 2009 by Bob and Catherine Thomas. We design and make single-sideband adapters for vintage radio receivers.

Bob is a retired electrical engineer, and has been a licensed amateur radio operator since 1958. He designs and tests the company's products. Catherine is in charge of production and shipping.

We sell our products on-line to vintage radio enthusiasts worldwide.
