RS-6
is a spy radio, developed and used by the CIA and other public institutions.
A large number of the radios was bought by the
SAC (Stratecic Air Command)
It is more or less a miniature version of the RS-1.
The design is very similar, however subminiature tubes are used in the receiver and the power supply,
and a miniature tube in the transmitter oscillator.
RS-1 consists of three components, RS-6 consists of four components, of which two of them have the same size.
The power supply is built in two housings, which can lead to the conclusion, that each part should not exceed a
certain size.
The components are:
RT-6, Transmitter
RR-6, Receiver
RP-6, Power supply and
RA-6, Filter and accessories.
RT-6 is meant for 3 bis 16.5 MHz in in two ranges, at 6 to 10 W output. The built in CW key can be extended and allows a speed up to
40 WPM (words per minute). 60 WPM can be transmitted with an automatic keyer that drives the
tube cathodes directly.
RR-6 is meant for 3 to 15 MHz in two ranges, and can be tuned by crystal or VFO.
RP-6 can be connected to 70 to 270 V at 42 to 400 Hz. It also runs on 6V DC.
About 10.000 RS-6 and RS-6A together were built.
RS-6 also belonged to the on board equipment of some aircraft. In this case the hand crank generator DN-58
also belonged to the radio set.
[ There also was a RS-6A, consisting of RT-6A and RR-6A, covering
4.5 to 22 MHz. ]
