These PLL’s are described elsewhere in this document. Here’s the most comprehensive easy to understa nd reference guide to CB lpl PLL circuits you’ll ever need. Modification can be done by changing the loop mixing crystals or a better method is to change the BCD programming.
If these are combined they make up a 8 bit binary counter.
This chip is a phase comparator and programmable divider only. This is a great PLL. A better mod is to change the loop mixing crystal. See Order Form for prices. Modification is done by useing an external oscillator to replace the doubled 20 Mhz mixing signal coming from the 10 Mhz reference divider.
Does the same functions but in one chip. We’ve combined hundreds of CB models and years of PLL experience into a single handy reference source. This chip also uses 6 bit binary programming. Can be modified slightly by changing the programming to the pins. These two chips were paired to form a PLL.
This is the most popular PLL ever made! It uses a single Here’s the most comprehensive easy to understa nd reference guide to CB radio PLL circuits you’ll ever need.
This chip is a clone of the MB with a few changes. Modification c511 be done by changing the loop mixing crystal or controlling pin 10 on the MB It is used in conjunction with the MSL programmable divider. Like what you see on our site? All the latest C512. These are simplified illustrations showing exactly how a particular chip is used to generate all IF frequencies, downmix frequencies, Clarifier and SSB offsets, etc.
The resistor near Pin9 needs to be removed and a jumper wire with a ferrite bead put in its place to reconnect power to pin 9. Also included is a unique section of specially prepared PLL chassis diagrams. In the Export versions it has a pair of MC binary Plll connected to it, this enables more Ncodes per mixing crystal.
The CB PLL Data Book for CB Radios
As this radio is not as broadbanded as previous Unidens it might not be 5c121 the expense of the new chip. This is “must” reading for every true CB hobbyist or serviceman!
P,l is the only reference especially written to include non-technical people and serious repairmen. These chips use a double ROM set to deny illegal modifications.

Also has a pair of MC binary adders to increase Ncode range. This will give 40 channels exactly Khz below the standard ‘FCC’ channels ie. These models used the famous ‘sardine can’ type sealed PLL unit.
The MB is used in the popular Uniden chassis. It has a possible channels via 10 bit BCD programming. AM models can be modified by changing the programming or loop mixing crystal. See Secure Order Form for prices.
CB PLL Modifications List
Simple but detailed text and illustrations, all carefully prepared and written for the average person. Pin 3 controls this operation. Professionally typeset, bound and illustrated, the big new International Edition covers all the most popular, classic PLL circuits.
This radio is useless without the mike controller. This is the only reference especially written to include non-technical people and serious repairmen. Used in alot of the newer Uniden ‘clone’ export radios. To send us an email now, click here.
Covers all the most common chassis, including:
