It has already been done. The SCR 274 N or ARC-5 series included a
receiver which covered most of the AM broadcast band. With a wire
connected to its antenna post, a unique signal appears every 10 KHz
Across the dial. All that`s needed is transistorization. I used one of
the originals with a 12-V dynamotor as a a car radio for years.

If you can find a R-390 or R-392 and copy the front-end of that sweet
receiver, - THEN you'd have a fine one.
