[ARC5] Tuning box

[BenG4BXD]

Ah, that explains that question Robert, many thanks.

I have a rx as well with R-31 on it in yellow so come on chaps, what 
does it mean?

Ben,

I don't know about the yellow stamping but on C-43/ARC-5, the third 
(right hand) position is for the R-28/ARC-5.

Just been making a display board for a few Command bits. I found a
BC-450-A 3 dial rx tuning unit.

On it, in yellow, it says "6V AC  R-31  Tested"

What's an R-31?

I also found a C-43 ARC-5 tuning box, but it only has 2 tuning dials
but three sets of connectors and mode/gain switches.? Why ??

Ben.
