The R-200 was manufactured by Motorola with Order Number 116-PHILA-52-93
(1952).  I have three of the receivers.  They are difficult to repair when
because of all the connections to the turrets in the RF unit.  Motorola
Incorporated put out an instruction book for Radio Receiving set AN/URR-29
and Radio Receiver R-220/URR dated 21 June 1954.  Addenda to the
Instruction Book were published on 1 February 1955, 6 June 1955, 15 July
1955, and 26 September 1955.  The Army version was TM-11-882 published in
November 1955.  The weight of the receiver is 96 pounds with an additional
38 lbs for the CY0959/URR case.  Frequency coverage was 20 to 230 MHz in 7
bands.  

Cheers, Paul Bernahrdt
