In my net search I did see that but needs to be connected to the DigiMax.
the one I saw on a site explains>
remove the 8719 install socket and plugin the channel module.
then mount the rotary sw.
No hooking to a digimax.
So Im hoping to track this down as it looks very interesting for a channel kit.
Says it will work in both the 8719 and 8734 boards with the 11.3258 xtal.
You are on your own with this one, only blame yourself for even thinking it's an easy job. A job like this will prove that you can fix a radio, as you get to that part while doing the mod and the radio stops working ..... then hope the kids aren't around to learn new words.........
The first thing you should do is take out the original PLL, put a socket in its place, and then modify the trace circuit to work with the 145106. By the time you figure out what jumper goes where you'll know enough about PLLs to continue. Whatever you do, don't let the smoke out. There is enough information on the internet to do that much. It will work to this point.
The best place to start is with schematics of radios with the 145106 PLL, then finding out that the 8719 PLL can also be used in those same boards, but in different radios proving that it can be done.
Once you can turn the radio on and be able to change to whatever channels or frequencies you have with the stock channel selector..... you'll have a basic understanding telling you what needs to be done to keep moving on. This is where you'll spend more time researching on the internet, the problems will snowball.
The obstacles; will be getting to all the available frequencies, broadbanding TX and Rec, and then finding out that the VCO will soon stop working not letting your dreams come true even though you know they are in there. There is information out there on how to modify the VCO, but soon enough you'll find that it's not enough and it makes you study the VCO operation even more.
At this point before making a mess of a good radio ..... you'll rewire and put the 8719 back in the radio and hope you didn't screw up any of the original settings.
It would be cheaper to buy a "Radioddity QT60" radio that already has everything you wanted in the 8719 radio ........ and hope you have a ham ticket to use some of those frequencies.
Make the right choice ...... "Use your mind!" (Rick and Morty S7E7 2023)
