[Milsurplus] Aircraft Radio Corporation T-15, -16, -17

[Hubert Miller]

Cleaning up some old mail.
I recall reading in an article on Collins Radio ( in E.R. magazine, maybe ? ) that Collins had prewar sold some bomber aircraft radios to Colombia.
It seems there's no documentation surviving on these radios and no one alive has ever seen even an image. "Sunk without a trace". 
But this is something to weigh considering what radios the So. American countries militaries used. It was not just cast-offs. 
I was told years back that the Mexican Army bought up a bunch of those SCR- 583  ( BC-1209  ) radios that G&G New York was selling. But who
knows, there are a lot of unsupported stories.

Well, I understand, but I didn't pull that theory "out-of-the-air" (pun intended).  I do have some basis for the idea.

Military Aircraft equipment, Standard 1920s- to early 30s, until SCR-183 came out:

SCR-133 Pursuit Plane Set, Rcvr 250-1750 KC, 
                Xmtr 860-2000 KC AM
SCR-134 Aircraft TX 400-850 KC, RX 250-1500 KC
SCR-135 Scout/Bomber Radio,  250-2000 KC

1926 Navy Comm Plan, Aircraft Freqs:
District aircraft: 1105-1295 KC
Air Squadrons and Aircraft Shore Stations: 550 KC Naval District Patrol Patrol Planes: 605, 685, 755 KC (Etc.  There is much more but I think this sufficient).

Mike Morrow:   You are the expert in this 
pre-war aircraft gear.  Comments?

If a U.S. Navy squadron is going to patrol the area around the Panama Canal and has been ordered by "pols and generals" to "good neighbor" 
co-operate with Costa Rican patrol aircraft, the Costa Rican's aren't likely to have "modern" equipment right away; they're going to have what they bought 10 or 15 years ago or "Uncle Sam's Hand-me-downs"
like SCR-135.  If a patrol of Hellcats wanted to talk to an unknown surface vessel, 500KC would likely be the only means short of dropping a note with a rock and hoping someone there reads English.

If a list member has any contacts with military historians in places like Costa Rica or Columbia (or Iran or Morraco etc.) that have knowledge of what indiginous military patrol aircraft carried for comms in 1940-44, it would be interesting to hear.  I've got a standing bet of coffee and donuts we'll find it was MF stuff fitting the conventions of late 20s above.
