SUBJECT: Inspection Report No. 4 - RS-101 with
1. Project Description:
The RS-101 is a 2 - 24 Mc/s solid-state radio intended for para-
military operations. The semiautomatically tuned transmitter produces
20 watts in the CW mode and 5 watts in the AM mode. The receiver is
capable of receiving AM, CW, or SSB signals. There are.provisions for
a battery and either a synthesizer (OS/B-100) or crystal matrix. The
ES-101 weighs 10 pounds and is approximately 7 1/4" x 12" x 4 1/2".

The transmitter portion of the RS-101 is being plagued with the
equivalent transistor problems that beset the RT-66(P2). The engi-
neering model RT-101 uses RCA transistors in the final for which RCA
has canceled manufacturing plans. ITT and Motorola transistors are
under active consideration and are being tested as substitutes.
An RS-101 "on-the-air" demonstration was conducted at selected
frequencies between 7 to 20 Mc/s. The radio, including the semi-
automatic tune feature, performed in a satisfactory manner. Effort
is being concentrated to increase the power output in the "worst
case" area. Between 16 to 18 Mc/s the RT-101 puts out ap roximately
16 to 17 watts. This goes up to about 19 watts at 19 Mc/.
Internal construction techniques of the complete radio were
observed and constructive criticism was made regarding interlocking
the tune knob, addition of a fold down handle on the tune knob, and
minor aesthetic improvements to the front panel. The engineering
model RS-10l will be available for observati n in Washington for a
two week period beginning 29 July while observes their vacation 25X1A5a1
period.
