i changed to VHF from UHF and experienced the PI locking up
It turned out to be RF getting into the program cable
a few loops through a ferrite core fixed all my issues
edit : i run 1w into an external antenna
Thanks Len.

Thats a good point.

I get RF injection problems if I use the built in antenna, via the debugger cable connected to the radio. But using an external antenna, the problem is lot better.
