Other RATT RIGS
- AN/MRC-2 Series
The AN/MRC-2 series is believed to to be the first mobile RATT system and is described in TM 11-264. Documents show it was probably developed around 1947 and was an offshoot of the SCR-399 as was the AN/GRC-26. It was contained in three HO-17 shelters on 2-1/2 ton trucks and was used at field headquarters of large units for long range communication and for handling heavy traffic. It was a semi-permanent installation running 2 kw of power with one doublet antenna for transmission and two for receiving. Not many were produced and in my opinion was the predecessor to the later commcenters.
- AN/GRC-65
This unit is mentioned in a few documents but it is unknown if it was ever developed. It was to be a "Low Cost" version of the AN/GRC-46. It was to have a different radio set with manual tuning, rather then the AN/GRC-19.
- AN/TRC-75
Mounted in a Jeep M-170, this set was a 1 Kw AM, SSB, CW and RTTY unit used mostly for forward air control. It covered 2 MHz to 29.999 Mhz. The RTTY used the TT-297A/UG Mite. The Jeep also contained the ARC-55 for aircraft communication.
- AN/TSC-60(V)7
Mounted in an S-250 size shelter, this Collins built set contained commercial Collins HF-80 series gear and was equipped for full remote operation. Only 7 were known to be built in an attempt to win a government contract. Used the UGC-74(B) terminal.
