[Milsurplus] TCS receiver information needed

[WA5CAB at cs.com]

Thanks, Dave.  That saved me looking that up in SHIPS 242A.

Add TCS-15, Air King, exact date not known (to me) but circa 1951.

TCS-8, Stewart-Warner Corp, 1943.

TCS-12, 13 and 14 ran over into 1944.  Some TCS-12 components were built by 
Magnavox (CMX).  I had several CMX-46159 receivers here once upon a time.  Some 
of the 21881 dynamotor supplies were subcontracted to other contractors but 
still carried the COL prefix.  OTOH, a lot of the remotes (all models, not just 
the common 47205) were subcontracted to Magnavox and carry the CMX prefix.    
Likewise, some 47205 Antenna Loading Coils were subcontracted to Meissner and 
carry the CML prefix.  Plus CMX and CAQO.

There was also an early transmitter-only version, the 56Q.  But the manual I 
have is undated and I have no further information in that regard.  It came 
with either a low-power (220 volt) or a high-power (400 volt) power supply.

There were vehicular versions.  The WW-II one was the MZ (built for USMC).  
When installed in conjunction with the AN/ARC-4 it was known as the MAL.  
Basically an MZ combined with an MAH.  The Korean War variant was AN/MRC-6, which 
ran up to AN/MRC-6C.

A few were modified for use on submarines with the open-wire antenna posts 
replaced with N-connectors and with a different antenna loading coil.  AFAIK, 
any TCS transmitter or receiver with a UHF or a BNC connector on it is a ham 
mod.
