RCI-2950 Mod for 25 Mhz -33 Mhz

EXPAND YOUR RCI TO 25 MHZ AND 33 MHZ

There is a trick to expand your RCI over the factory programmed limits. Yes, I agree that it's not a very clean mod but it works great. So what _

This trick is to change the X2 crystal ( Quartz ) that is a 10,240 Mhz value one. You can experiment quartz from 9 Mhz to 12 Mhz ( It'll depend on what you have ). This modification will increase the coverage of your RCI from 25 Mhz to 33 Mhz if you make all the quartz switches. Be carefull, the frequency that will be indicated by the LCD screen won't be true of course. You will need a separate frequency counter.

May I suggest unsoldering the original crystal and replace with a mounting slot. It'll then be easier to exchange crystals quickly when needed.

DO NOT TOUCH TO THE OTHER crystals. It would cause problems.
