Just a note on channel capacity with the M1225 series. They were touted as having a capability for 20 or 24 channels. You could squeeze in 24 channels if you deleted certain features/functions on the radio. It's been too long, but I seem to recall that you would lose simple things like the ability to change the display backlight from amber to green, certain button functions, etc. The reason that it sticks out in my mind, was that I do remember seeing problems as you would approach 20 channels and try to do things like priority scanning. It seems they were pushing the edge of the radio's capabilities to get to 20 + channels, especially if you had Alpha tags on each channel - and used all the characters on the display. On a side note, I used to mess around with LTR trunking systems on the 1225 series before they came out with the LS models (and later on the PM400) - and a company named Scholer-Johnson made a plug in option board that would allow all types of features - including the ability to do multiple zones of 16 (possibly more?) channels. The software wasn't user friendly - I remember that you did NOT want to Read radios with the option board - just Write properly defined setups. I stumbled across the 3.5" floppies with the install files the other day, probably what brought this to mind.
