The CB PLL list 3/3





PLL List 3/3

The CB's are listed by PLL model. Find the PLL and then find the mod :)

SM5118
Models include:- Automatic CBR2175, Bowman CBR9940, Panasonic
CB-B4737EU/B474EU, Pearce-Simpson Leopard B, RCA 14T405/14T410, Chrysler
4048076/8077, Pace 8041/8046/8047/CB185/8092.
This chip uses simple 8 bit binary programming. The Pace 8092 uses  a very
complex scheme to produce a 455Khz SSB circuit.
Modification by changing the 12.250 Mhz tripler crystal.

SM5123A/SM5125B
Models include:- Cobra 18+/21+/25+/29+/33+
This is one of the newer ROM type chips. It has Ch.9/19 pins and an internal
LED display driver and ONLY 2 programming pins (UP & DOWN).
No chance of modification.

SM5124A
Models include:- Cobra 31+, K40-7, Realistic TRC 435, Uniden PRO
510e/520e/510XL/520XL/500D/530e/710e.
In this chip the VCO shifts directly from 16 Mhz on RX to 27 Mhz on TX by
switching in different VCO coil inductances. This is a very poor  design.
No modifications as far as I know (why would you want to modify such a bad
radio?)

TC5080P
Browning Baron/Sabre/SS-2, Cobra 132XLR/135XLR/32XLR/86XLR/87XLR, Tram
D62/D12/D42, Sears 562.3802/562.382, Kraco KCB4095, Sharp
CB750A/CB800A/CB2260/CB2460, Royce - some models with the 'sardine' can PLL.
This chip is part of a three chip combination, the TC5081 (Phase comparator)
and the TC5082 (Referance Oscillator & Divider)
Can be modified slightly by changing the programming to the pins. A better
mod is to change the loop mixing crystal.

TC9102
Models include:- Midland 76-860/77-861B, Sharp CB2170/CB4370/CB4470/CB4670
This chip uses 6 bit binary programming with pin 10 controlling the preset
Ncodes for TX and RX.
Can be modified by switching in new loop mixing crystals. 

TC9103
Models include:- Medallion 63-540, Motorola CT950AX, TRS Challenger
730/1200, Wards GEN-680A/716A
This chip uses simple 6 bit binary programming and a preset divider.
It can be easily modified by injecting new mixing signals from a external
oscillator.

TC9105
Models include:- Motorola System 500 CM550/CB550/CB555
This chip also uses 6 bit binary programming. It is very similar to the 
TC9106/9119 PLL except they use BCD/ROM programming to make conversions harder.
Can be modified by switching in new loop mixing crystals. 

TC9106/TC9119
Models include:-U.S.(TC9106)Cobra 18LTD/20LTD/21GTL/ 
25GTL/21LTD/25LTD, Craig L104, K40-8, Midland 200M/77-824B, President
P220/Andrew J/AR-7/AR44/AX44/AR711/AX711/P200/P210, Uniden
PC66/PC33/PC33X/PC55/PC55X/AX-43/PC-3/Pro-540e, GE 3-5804B
/5815A/3-5805/3-5804F, Realistic TRC425/TRC426/TRC427/ TRC473/TRC474, Teaberry
Stalker III, NDI PC101/PC102 
U.K.(TC9119)Audioline 340/341/345, Tandy TRC2000/ TRC2001/TRC2002,
Uniace 100/200
These chips use a double ROM set to deny illegal modifications. The only
difference between the US version and the UK version are the ROM codes.
No Modifications possible.

TC9109/MB8733
Models include:- Cobra 19GTL/19LTD, President VEEP/AR-14/ AX-14, SBE
LCMS-4/LCM5, Sears 663.38052/663.38009, Teaberry Stalker IV/VIII, Uniden PC-14,
Craig L103, GE 3-5804G/3-5816A, Realistic TRC216/TRC210/TRC411/TRC416/TRC429
This chip is similar to the TC9106/TC9119 PLL's.
Forget about modifications.

uPD858
Models include:- Cobra 138XLR/139XLR/21XLR/29XLR/89XLR/21X/ 77X, Palomar
SSB500(early), President Adams/Grant(old)/Madison(old) /Washinton(old)/Dwight
D(old)/honist Abe/Teddy R/Zachary T(old)/John Q, Realistic
TRC449/TRC457/TRC458/TRC452, Roybn SB510D /520D/AM-500D, Stag 357, Teaberry
Stalker 101/102/202/WKS1001, Courier Centurion PLL/Centurion 40D/ Gladiator PLL/
Spartan PLL/Rebel PLL/Rebel 40A, Fannon Fanfare 350F/100F1, Midland
79-893/13-883B/77-883,Teaberry T Bear/T command/Titan T/ T Dispatch,  
This is a great PLL. It has a possible 399 channels via 10 bit BCD
programming. The SSB models are very broadbanded enabling 200 channels.
Modification can be done by changing the loop mixing crystals or a better
method is to change the BCD programming.

uPD861
Models include:- SSBCDE Mk26, Pearce-Simpson Super Bengal MkII,
Contact PSC301, Wagner 510
BCD/ROM AMBowman CBM-6100, Colt 350, Convoy CON-400, SBE49CB, JC
Penney 981-6221/6255/981-6203/6237, Sears
934.380817/934.381107/934.381207/981-6203/6237, Realistic TRC468/
TRC440/TRC466/TRC467/TRC461, TRS 600 
Binary AMPanasonic RJ-3250/3450/3600/3660, Realistic
TRC424/TRC431/TRC456, Superscope Aircommand CB140/ CB340/  CB640
This chip is very similar to the uPD858, but this one gives you the choice
of either 8 bit binary or 6 bit BCD/ROM programming.
In the BCD/ROM models disconnecting pin 24,grounding pin 14 and switching
pins 7 & 8 converts them to binary programming.

uPD2810
Models include:- Audiovox MDU6000, Tristar 727,TRS Challenger 850/1400
This chip uses 7 bit BCD/ROM programming using several sets of
Ncodes,depending on mode and IF choice.
Can be modified by injecting new mixing frequencies with a external
oscillator/crystal switch.

uPD2812
Models include:- Audiovox MCB5000, JIL 615CB
This chip allows either 6 bit BCD/ROM or 8 bit binary programming. Pin 3
controls this operation.
Can be modified by changing to binary programming and then change the
programming on the pins.

uPD2814/uPD2816/HD42853/KM5624
Models include:- uPD2810Cobra 66GTL, Craig L150, President James
K/AR-11/Old Hickory, Midland 77-856, Realistic
TRC469/TRC420/TRC420A/TRC421/TRC422/TRC432/TRC441

Stalker XII/ Stalker V, Uniden PTC104 Trucker. 

uPD2816 SSB Midland 6001(79-006)/ 7001(79-007)
These chips use 6 bit BCD/ROM programming.
The SSB models can be modified by pulling pin 9 HIGH. This will give 40
channels exactly 455Khz below the standard 'FCC' channels (ie. 26.510 - 26.950).
The others can be modified by injecting new mixing frequencies  with an external
oscillator/crystal switch.

uPD2824
Models include:- Cobra 146GTL, Midland 6001/7000/79-260, Pearce- Simpson
Super Cheetah, President P300/AR-144/AX-144, Realistic TRC451/TRC453/TRC465,
Sears 663.3810, Uniden PC244/PC122/Pro-810e/Pro-640e, Craig L132/L232, Wards
GEN-719A
The only ncodes available are 91-135.
Can be modified by injecting new mixing frequencies with a external
oscillator/crystal switch.
