RV-4C
RV-4C REMOTE VFO
The RV-4C is designed for use with the TR-3,
TR-4 and TR-4C transceivers. It permits reception, transmission, or both transmission and reception on a frequency removed from the VFO setting
of the transceiver, but in the same band to which
the transceiver is tuned. The RV-4C consists of a
highly stable permeability-tuned solid-state VFO, a
cathode follower, associated control circuitry and a
5-inch 4 Ohm speaker.
The unit is housed in a cabinet which matches the
transceiver. An AC-4 (or AC-3) power supply can
also be housed in this cabinet. The dimensions are
as follows: 5-3/8 inches high,
and
11-l/8
inches deep. Weight is
INSTALLATION.
For use with the TR-4C it is necessary to plug the
RV-4C into the RV-4 plug
the TR-4C chassis. No jumper need be removed
when the unit is installed nor is a jumper plug
needed when it is disconnected.
To operate the RV-4C with a TR-3, it is necessary to remove the bottom cover of the TR-3 and
remove the jumper wire between pins 2 and 8 of
the RV-3 jack (52). Replace the bottom cover of
the TR-3 and connect the RV-4C cable to
Connect the speaker lead to the 6-inch lead protruding from the power supply power cable connector.
When the RV-4C is disconnected from the TR-3,
it is necessary to insert a jumper plug in the RV-3
jack. This plug should consist of an 8 conductor
male plug (Cinch Jones Type P-308 with either the
CCE, FHE, FHT, or CCT metal caps-remove cable
clamps) with a jumper wire connected between
pins 2 and 8.
NOTE
It is necessary to ground the RV-4C
chassis to the transceiver chassis and to a
good earth ground with a short piece of
braid.

Main Tuning control determines the frequency of
the VFO and is calibrated in exactly the same way
as the transceiver VFO. The RV-4C FUNCTION
RCV,
control has four positions: OFF,
and XMIT.
In the OFF position, the unit draws B+ and filament current but does not provide any output. The
transceiver will transceive normally.
In the RCV position, the RV-4C determines the
receiving frequency and the transceiver VFO determines the transmitting frequency.
In the RCV/XMIT position, both transmit and receive frequencies are determined by the RV-4C.
In the XMIT position, the RV-4C determines the
transmitting frequency and transceiver VFO determines the receiving frequency.
The PTO indicator lamp is located to the right of
the PTO dial. This lamp lights whenever the RV-4C
is being used to control the frequency.

OPERATION.
The RV-4C has two controls: The Main Tuning
control and the RV-4C FUNCTION switch. The
If the AC-4 (or AC-3) power supply is installed in
the RV-4C cabinet, it will first be necessary to
remove it from the cabinet by removing the four
screws holding it to the bottom of the RV-4C
cabinet and sliding it out the rear.
