[Milsurplus] Hallicrafters EP-298 AC Power Supply for BC-348-Q Photos

[Thekan, Paul]

Maybe it was size… The BC 348 is much smaller than the SP 200, and while close to size on the BC 342 , the 348 had the LF freq coverage the 342 did not have. Maybe that was a reason.

Who knows….

Pretty good argument, looks like official packaging. Having seen the quality of the workmanship, lack of AC fuse and the amount of work required still have to question what’s the point? Installing the AC supply in that receiver won’t give you anything that was not available in several other receivers that were intended for ground operations, yes it can and may have been done but in the end to quote Uncle Joe “you’re putting a saddle on a cow” when there were horses available.
In the Ham and SWL world everyone converted the receivers to AC operation being they were cheap and available. Most Hams had no source for high current 28 Volts DC at the time and there were many donor broadcast receivers around to provide useful transformers. If you were lucky you would purchase a surplus BC-342, SP-200 or maybe a AR-88 and not have the issue of building an AC supply but with the abundant amounts of BC-348 receivers and command set that flooded the market there was ample opportunity for selling and building AC power supplies for all. But in spite of all that cant see beyond may one or two small applications where the military would want to do this.
It’s a long shot but is it possible that they provided a lot of the receivers to the MARS system of the time and decided to do a government group buy to give to those secondary users?
