HTX-10 freq expansion with resistor?

Help Needed/
There must be someone, somewhere globally who can place thier hands on one of these Sanyo chips. see attachment.

The important part of this is the fact it must be SY204 Sanyo LC72322 which has been pre programmed into the CPU.

The removal and fitting is not an issue for me just the fact there must be some spares out there as many radios had these fitted.

Here's a data sheet from alldatasheet.com. Turns out the program contents are a custom feature for the radio manufacturer. I'll guess your description of "SY204" indicates the radio-specific program code inside. The data sheet says nothing about how the program gets loaded into the chip's ROM. Gotta figure it can't be altered. Since it's essentially a custom part, there will be only one original source. Like looking under rocks.

    Hello gentlemen and Ladies. I have the dreaded RCI-2990 receive issue where my radio gets distorted when people get close to my location. I found the C90 Capacitor, but I can not for the life of me find the C89 capacitor. Can or does anyone have a picture of the exact location of C89 ? Thank you in advance, Wes
