General Description:
The Telex model RKP-4 beltpack transceiver is a
component of the RKP-4 wireless intercom system.
The RKP-4 is intended for use as a belt worn wireless
full duplex intercom radio for use in a professional
installation such as television or cinema production.
A RKP-4B base station can be used with one RKP-4
beltpack. The RKP-4 transmits within the 614.1 to
746 MHz range (TV Channels 38-59). It receives in
the 482 to 607.9 MHz range (TV Channels 16-36).
The TR-1 transmitter operates on a single frequency
within an 18 MHz wide section of the transmit
frequency range. The receiver also operates on a
single frequency within an 18 MHz wide section of the
receiver frequency range.
Typical transmitter conducted output power is 50 mW.
The RKP-4 transmit power can be set to automatically
reduced when the unit is close-in to the base station to
aid in intermodulation reduction and unnecessary
transmit power.
Operating frequencies can be selected from pre-set
groups or the user can select special operating
frequencies within the 18 MHz wide allotments.
The Rear LCD display and buttons plus the talk
function switch, is located on the back panel.
