[Motorola] Radius GR1225

[KB0NLY]

The version I have, I don't remember which version number, the shift trick 
didn't work so I had to hex edit it to change the bandsplits.

The last one I worked on the owner wanted a 442/447 pair in it and the VCO 
wouldn't lock without a random error now and then on the receive radio at 
442, so I had to tweak it down a bit, not a lot of work but still needed to 
make it reliable.

73,

Scott
