2.3 Product
Description
The
Midland model 71-506-10D
transceivers represent a great advance on the previous rugged & time
proven KG106 transceiver. They consist of separate modules all housed within one rugged, compact
mobile cabinet. The receiver, the transmitter, and the PA Unit are each enclosed within their own diecast
housings that are directly mounted to the main chassis. A full-featured logic module controls all
parameters of the radio under the control of a microprocessor. The RF Power Output is 1 - 10 Watts on a
continuous duty basis. The CTCSS module supports all EIA tones, which may be set on a per channel
basis during radio programming.
The
71-506-10D
is supplied with TX and RX antenna ports to allow connection to an external duplexer or
feeder cables. Space is provided inside the housing for an antenna relay or mobile type 6-cavity duplexer.
