GP300 help

[anautofix]

I have a UHF 8 channel GP300. It was working fine till a Ham friend of mine decided to change the installed freq. He used what looks like a european software for the GP300 and a home brew ribless adaptor. The radio now will only function on chanel 1. I used my authentic rib box and software and I can get the radio to take program ...I can see the newly installed freq. but there is no power output on any channel but channel 1. I even had an older codeplug I saved and it takes the program but has the same operation...channel 1 works only...... What can I do?? Help! I also come to find out the software was run on a XP machine. I thought XP was taboo with MOTO programming. That is why I held onto mt win 98 laptop.

What happens when you go to past ch.1 ? (Do you immediately get an error tone from the radio or does it Rx on these channels). What extended model # comes up when you read the radio now ? (Should be P94....... if the radio wasn't hacked into a euro version)

the model is showing p94ypc20d2 The radio will receive on the other channels...but barely.....its deaf.........never was.... I was always told never to use a newer computer with xp to program moto radios....any truth to that?

What if anything can I do? Or is the radio a paperweight? What do you believe he did wrong?

The model# looks OK for a 438-470 radio. 386/25 machines are about the best platform for this era radio but haven't heard of anybody lunching a GP300 using too fast a machine. The offshore RSS or the homebrew cable probably would be a more likely source of caussing a problem. If you have another with the identical model# give a clone a try if this doesn't do it the tuning data may have been skewed. Probably a recoverable error in the codeplug or tuning area.

Looks like an attempt was made to expand a radio that can't be done.
