On the topic of Marine Band radios and on Mark's recollections of the SCR-269 direction finder... they were popular with fishing boats post-war. I don't know if there was a commercial company refurbishing them. There wasn't much work to do, maybe just check them out and fabricate new wiring harnesses. I have a complete set that I have configured as a hands-on display for the aviation museum in Willow Run Michigan. https://yankeeairmuseum.org/ The process included replacing the Micamolds (putting new tubulars took less effort than checking them).

Atttached is a progress report I did for them last year. The set is now complete and waiting to be picked up by one of the Museum's pilots. I had the LP-21 for years on a high shelf until one day I moved something the wrong way and Ka-boom, down it went onto the floor, cracking the housing. (lesson: never store anything on an open shelf behind anything else). That was a blessing in disguise because it justified cutting a hole in the side to reveal the loop in action.

The whole ensemble works beautifully.. a thrill to see the loop and the indicators swing into action when you tune in a station!

Correcting voice to text typos in previous post

During the 60s the primary fishing boat comms were done on 2-3 MHz AM. Somebody was converting SCR 269 (BC 433 rcvr) ADF systems to operate in the marine band. The control box was beautifully modified with a newly manufactured tuning dial that had the marine band on it. Jack Antonio very kindly gave me on of these modified BC 433 control boxes which exactly matched what I saw as a kid.

Who did these very professional conversions? I saw quite a few of them in the 1960s.

Speaking of fish boat conversions of mil radios
I’ll repeat a question I’ve asked from time to time but received no answers or substantive clues.

I grew up in commercial fishing, my fathers trade. I started working on deck at age 11 in and skippered my first boat in 1967 at age 17. I worked my way though several college degrees commercial fishing during summer breaks.

I think Dave Stinson is the SME for that W.E. boat radio. Do you mean the one with 6L6 power oscillator mod by single 6L6 ? If so, i have one i would sell reasonable, FOB Oregon. USCG manual copy included.

I recall seeing online one rebuilt postwar by Spanish company for fish boat.
