NOTE: ON ALL KITS, RADIO MUST BE IN ORIGINAL CHANNEL CONFIGURATION. ALL CHANNEL MODS MUST BE REMOVED AND COMPONENTS RETURNED TO ORIGINAL CONDITION.

A NOTE ABOUT PLL IC'S

The RCI8719-97 is a 7 bit device, but the internals of the IC do not allow it to control the VCO as well as a -99. I recommend you replace it with an RCI8719-99 or MMB8719 and change the crystal. You’ll be much happier with the results. Also, remember if you do this, do not connect A14 to +5 volts.

Some of the newer radios are coming with the MMB8719 in them. They are different from the -99. Be sure to adjust VR1 as noted in the instructions. 

Also, I've noticed that techs sometimes try to adjust VR1 by watching the counter in the radio. While this will get the radio on frequency, the VCO may not perform correctly. Be sure to adjust it using a DVM. VR1 is very touchy at the specified voltages. You will see this in the DVM reading, but not in the counter.

UNIVERSAL KIT NOTES

-For the 919, 929 and 979, A13 must be pulled high (+5volts).

-For the 8719-97 PLL radio's, A14-only must be pulled high (+5volts).

 -In the 919, 929, 979, a pull down resistor is required on PLL pin 10, P6. Add a 10k ohm resistor between pin 10 and ground.

COBRA KIT NOTES

COBRA KITS ARE NOT PLUG AND PLAY

- In the Cobra's, you must replace the MB8734 PLL with an 8719 PLL for the board to work.  (For any channel mod to work for that matter.)
