[ARC5] AN/ARC-2

[Jay Coward]

Tim and Ken,
 I had the -2 and the -2A. On both the meter was "sticky". I looked for ever for replacements but they have a unique scale and a 2 mA full scale which I have never seen before. There is a trick to getting the dynamotor back in once you remove it. The connector pins are at a slight angle off of vertacal so it won't drop in. You sort of have to roll it in. Once you do it a few times its easy. The oscillator is very "Collins" and similar in construction to other sets by them. The chassis is built like an "H" with just about everything accessible. The manual shows a really cool cradle to mount the chassis for troubleshooting.
 Robert Downs has excellent repro's of the manuals. Worth getting.
 Good Luck with it!
 Jay

Hi Ken - Yeah, we were imagining they were used in larger aircraft.  Shoe-horning a 274N or ARC-5 components into space available in a fighter is easier than fitting one big, heavy lump in someplace.  (We were imagining it would also serve to augment the pilots aft seat armor if it were placed in a fighter ..haha..)

As you said, seems it was functionally/operationally equivalent to the HF Command Sets, all in one box.  Looking forward to seeing the innards.  I think Dave or others wrote up a scheme for fabricating a rear connector, it seems to be unique.  This one had no mount but otherwise a real beauty so far....It is the 2A variant...

Thanks,Tim

Ah, yes. I had forgotten about the spanner. Mine is still there too. Jack mentioned that.

Yes. Exactly. Covers almost the entire Command Set frequency range and not much more, 
although to my mind, it is a LOT heavier and far more complex. It is a very, very nice set.

Please let us know how it works.

As I mentioned, and as I remember it, most of those were used in transport aircraft, though, 
not fighters, etc.
