Ladies and Gentlemen,



We have good news and bad news. First the BAD news.

Mitsubishi has discontinued the following final output transistors:

2SC2166

2SC2312

2SC1969



Now the good news.

Most CB and Amateur radios will begin using MOSFETS instead of transistors. What does this mean?

Well, MOSFETS are capable of much better stability over a greater freq. range. They are also capable of higher power output with a smaller package. So, in the near future, we should see our transmit quality become far more superior than it has been.

Companies like Icom have been using this technique, for some time now, to produce radios that will cover a broad array of frequency ranges out of one unit.

    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
