The diodes for the 2022 are: D42: 68-88 MHz European band. When installed, it restores this band, removing 30-54 US band. Also, circuits need to be realigned. D43: 800 MHz band. When installed, permits reception of this band D44: Cellular band. When installed, it deletes the reception of this range. D45: Cellular step. When installed, it changes the step from 30 kHz to 12.5 kHz. 30 kHz is standard. I also have some mods for the 2004, 2005, 2006, 34, and Bearcat 200XLT, and frequency lists for the Minneapolis, MN and Grand Forks, ND areas. Have fun... Greg Putrich UD158168@ndsuvm1.bitnet
