[Milsurplus] Service life (was Collins Book

[COURYHOUSE at aol.com]

I went at Luke AFB  starting in 71 and we have  2 ea BC 640 and  BC 639!  
they were the prime VHF Guard  Channel  and one VHF  tower chan.     for  
civilian aircraft. A military airport  has to be able to talk to ANYTHING.... 
funny thing was  the  ARC-3's  that were the backup units! the ARC-3's  were 
the  avionics  groups  responsibility. When I left Luke, PROJECT RIVITSWITCH 
was switching  out all the   tube  stuff for solid state and hybrid equip,  
 I wish I had gotten that 640 that had  serial #2 on the rack.   I  will 
still buy it  for the museum here if it ever  shows up!
 
I also worked on  GRC-27 GRT-3 GRA-53 Collins KWM-2  R-390 and  some misc  
there. and of  course look  for these units too.   I have a GRC-27  receiver 
 so far. Need the rest!
 
Thanks,

But I have a feeling 
that the winner might be the much maligned BC-640 as  two were surplussed 
out 
of Barksdale AFB between 1969 and 1971 (I bought  them but can't for sure 
recall what year).  Note that the TDQ/RCK  pair were the Navy counterparts 
to 
the BC-639/640.  And that the Navy  and Blue Suiters had a mandate to be 
able 
to talk to civilian  aircraft
