This is the legendary Tram D-201A 40 channel AM/SSB base station. Both the D-201A and it’s predecessor the Tram D-201 23 channel AM/SSB base were top-of-the-line units in their time. The build quality of Tram CB radios is excellent. Today, they are highly valuable collector’s items. Every so often, you will see one on eBay. Prices range from $300 to more than $500, depending on condition.
