How do I use a Motorola MC145152 to control RX and TX frequency of a 27MHz CB radio from 26.965MHz up to 27.805MHz or any upper or lower frequency close?
Hi Fernando,
Looking at the data sheet, it should be as easy as just selecting the correct binary code on the pll ic. I played about with some old ssb sets a few years back, the only problem you may have is getting the rf o/p stage to cover such a wide range.
I used a pic with lookup tables, used i/p from channel select and a switch to select the band and o/p the relevent binary code to the pll.
