Other Uniden CB Chassis - Applications

The information in this book can 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 oscillator crystal in the 15 MHz range. It is AM/FM/SSB and some versions also have the British CB band which is switched in by another crystal on a separate sub-PC board.

Cobra 148GTL, President AR-144/AX-144, Midland 6001/7000 (new version), Realistic TRC451, 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.
