[ARC5] Post-War R-13 VHF (came in 12 and 24V versions)

[Scott Johnson]

Not too hard to move it to 2M, a little capacitor plate bending on the osc
and rf amp stages. Just like tracking an ARC-27!

I used to see a lot of these so modded back when I was a kid. (I got a lot
of cast offs from old hams)

Me too.

Well, for those two which cover the 190 - 550 range, and the BC band, one
can replace the 
tuning capacitor with one from a junked BC-453, then add the dial.

But your Type 12 better be hacked beyond restoration to start with. Mine
sure are. Mine 
look almost as if someone took an axe to them. I cannot imagine what was the
reason.

Also, none of the Type 12s has a BFO. It has a noise-limiter instead. And a
much better 
AGC. Both features make them hard to use for CW or SSB.

These reasons are probably why there are so few Type 12s being used by hams.
There 
weren't all that many of them made anyway.

I would sure like to even see one of those tunable VHF receivers, the R-13.
