The fact that it has become far more stable can only mean that it is far more reliable than it was before the mod. How this translates to a cold mobile environment is not in my corner to determine. Not a gambling man; but my money is on it being more stable in a cold environment simply because what i consider a very serious deficit in the radio had been changed for the better.
Camaro1 said he would mod his radio and give it the test. We will have to hear from him and wait. Don't expect anything miraculous; just better than before.
Doubt there too many of these radios even being available from those that retailed them at this point in time . . .
I hear there is more coming soon
