Yes. I've managed to acquire all the components for an SCR-183 system. It's been in the queue for a few years.... but...
At the recent Reading Airshow, I was approached by someone that wants to have a display of a P-40B radio setup and asked if I'd help him. He said the radios were the SCR-283 and provided me with links from which he obtained this info. For next year, I think it would be nice to have my SCR-183 up and running next to the SCR-274N.
I do need a junction box, but from discussions from Mike Hanz, this will probably need to be hand-made.
I'm targeting Reading Airshow 2027 for the SCR-283 (Lord willing....)
