[Milsurplus] Information on US ARMY AAF 1946 "Plan 62"?

[Jim Klotz]

Hi all,

I've been working my way through some unit historical reports for US Army
Air Forces, Airways and Air Communications Service, 100/101st AACS Squadron
for 1946 and 1947 on microfilm.  This Squadron provided Communications, ILS,
and later Radar GCA for AAF bases in the Southwest US.

In and around 1946, there was a large scale project underway in (at least)
this group of AAF bases to create a network of air/ground and interphone
communications, the "Army Air Forces Military Flight Services Communication
System" known as "Plan 62."

I'm wondering if any of you guys have or know of references to or
information about this project/system.  I would appreciate any information
you could pass my way.  If it would be appropriate to forward this to other
Mil Comms email lists, please do so.  Please feel free to contact me off
list at: jklotz77 at verizon.net

At the moment, I have a few details at hand to help ID this scheme:

Part of this system was three VHF channels at each airfield; Channel "A" was
21.78 MHz lower in freq than "C" channel.  "D" channel was 2.70 MHz higher
than "C."  The frequency 137.88 MHz was mentioned but I have no idea which
channel and 140.58 MHz was mentioned as the "emergency channel," which,
because of another separate mention could have been "D."

Different antenna systems were in use such as 1/2 wave dipoles, "RC-81's"
and "AN-188's."  The AN-188 antenna was blamed for low output at certain
frequencies.  Receiving antennas mentioned were; "AN-188" and "RC-81A."

There are quite a few communications tidbits in this material.  I've done a
'quick and dirty' extraction of some of that stuff and put it in a PDF
file which is here:

I hope this is of some interest to you guys.

Best regards,
