New pll 8719 channel mod kit.

Post by dj56 »

Hope I can post pictures of what im posting about.

I was able to get 2 channel kits for the pll 8719/pll 8734 boards just need the 11.3258 xtal

You remove the pll and install a 18 pin socket. Isolate pin 10.

Then plug in this kit has 5 position rotary switch.

I was able to get my Washington to go to 28.535 and down to 26.515.
I was able to get the radio to go to 29.325 with a retune for high but went back to the 28.535 and 25.515.

there are a few things to do to get it to broadband the vco and receive.

by the directions this kit has channels 26.325 to 29.325 if you can get it to tune for full coverage.

I have confirmed the 18 pin on the kit board is a MC145106P i removed the chip and plugged in another one.

would anyone have an idea what might be the 14 pin chip on board working with the MC145106P?
