What I can not remember was if the program prom was band specific. I will go look. I have a vhf and a couple of UHF rigs. I always just left the programming proms in the radios I used. If they are in fact different then yes the limits are in the programming prom. I had not thought of snooping the data buss. You are right the channel info is held in the radio memory. So that might be another way to address the info. Pun intended.

Would make sense it's in the Program Prom, but who knows??? Was going to take a look at "mapping out" the eeprom. Though that might be an easy way to get 1-2Channels into the radio,however, It's an old SERIAL based eeprom.(MN2802) Don't have access to anything that might even read it...

I think thats why I'm not the only one(based on the off-line requests I've recv'd)that would like to use these O.O.B. Al, I thought about the "Xtal-Change" approach, but like your friend found out,...sorta not worth it..but thanks for the idea... Thanks to all for the ideas...Maybe someone will still chime in with some "good News"...Don't want to give-up just yet... 73 Carl KA9GPX ------------------------------------ Yahoo! Groups Links
