Would likely be the ATB/ARB, which  shows-up in period photos
more often than one would expect.
IMHO, ATB/ARB parts and accessories are hard to find
because most of them got used.
One semi-educated opinion,
worth every penny you paid for it ;-)

Subject: [ARC5] SBD HF radio ?

Anyone know this?

SBD-5  had only 2 channel MHF radio

SBD-6 added 4 channel VHF radio

 

This fact from 2 pages i had saved years ago, from ? a now extinct militaria magazine ?

Very unfortunately, i did not title the pages with the source.

 

My question is, what was the 2 channel HF radio ?
