Convert it to a 90-5 ;D There is a cap you can play with at the top of the tuning coil inside. Forget which way to go but you change the value and you can make it work. If you google it you will find the info. it is out there. No time right now or I would get you the link. If you have no luck I will find it for you when I get a chance.

not much out there on it. I called one of my CB shops and i got the typical run around answer from the jerk tech "Thats an old radio you need to just forget it and move on. Why do you guys keep these old outdated radios on the air, ill never know. Oh, and BTW there nothing you can do to that Siltronix VFO except get another one that will work on your radio."
Thats the answer i got just a bit ago...

Here you go. Just look mid way down on the right of the schematic and you will see which cap is for which model . Just change the cap and tweak the coil for the correct frequency. www.cbtricks.com/miscellaneous/vco/siltronix/model_90/graphics/siltronix_vfo_model_90_sch.jpg

That's because most of the typical hack shop CB "technicians" only know how to clip limiters and spread coils on the Chinease junk that they currently make. Owners of old radios, that require more work than their limited expertise allows, are simply told that it's not worth it, and then they usually try to sell them some new POS.
