OTHER UNIDEN CB CHASSIS - APPLICATIONS
The information in this bookcan be applied to many other
Uniden CB radios since all the current production units
are basically the same.
Examples are:
Stalker 9-FDX, President McKinley export (PC 893).
This uses the MB 8719 and is an 80-channel transceiver
using a single loop Oscillatorcrystal in the 15 MHz range.
It is AM/FM/SSB and same versions also hâve the
British CB band which is switched in by anothercrystal on
a separate sub-PC board.
Cobra 146GTL. President AR-144/AX-144, Midland
6001/7000 (new version), Realistic TRÇ451,
Sears 663.3810, Uniden PC-244. This is basically
identical except for the lack of FM, and the PLL circuit
which uses a uPD2824 ROM chip..
