[ARC5] Talking to Airplanes From the Ground

Mon Aug 2 09:29:57 EDT 2021

A 120 VAC power supply existed for the SCR-522.  RA-62?
I have had a couple of those, repurposed for other usage.

I haven’t been able to find any of the photos discussed in the previous threads so I apologize if these photos have been shared before.

They are improvised 274N’s in jeeps doing airfield control work. Note the 24 volt batteries in one and the aircraft Homelite 28 volt generator strapped on to the front bumper of the other. I would wager that these were two of the main options used on airfields so modifying the radio sets were not necessary and spare equipment would be readily available.

They used 274N’a and 522’s in air traffic control towers as well presumably with 28 VDC power supplies.

The Homelite generators were issued with every B-17 and B-24 from the factory but were often pulled from the aircraft before they flew on missions to save weight. I think this would have lead to a surplus of these generator sets for such use on airfields.

Thanks,

Gang,

I'm with Hue on the SCR-694.   In addition to being waterproof it was a lot lighter than the SCR-284 (a horse designed by a committee.)  The design lived on for some time after the war as the AN/GRC-9.  The latter set was humped around by the original cold-war long-range recon units.  Both radios load an end fed have-wave wire really well, so you can leave a bunch of antenna parts behind.

Here's the poster from the WWII Tactical Communications display in our museum:

I think I am partial to the SCR-694 and like. I recalled now that the TRC-2 transceiver was actually

the first 'surplus' radio I ever had, and that was around 60 years ago. It unfortunately was lost,

which makes this uncommon radio all the more uncommon. I still have some BC-1306s and

another TRC-2. At one time I thought of trying to go for the whole TRC-2 setup, but now that's

looking very impractical and unrealistic.

Chuck Waite about 25 - 30 years ago told me about a "1306 net" he and some others had going

in PA area a few years before that. That sounded like real fun and only whetted my appreciation

of these little gems. I also recall seeing at a Goodwill store a book on Christian missionaries in, I

believe, the Amazonian Peru', and it had a photo of a missionary with a full BC-1306 setup with

handcrank gen. I kick myself now for not buying that book. The price was certainly nothing.
