Igor, Minus 10C is about plus 14F, which is well below freezing. I would think that was adequate for a good test of output at cold temps.
The experience that I cited about an early rig not operating for several minutes was at about minus 30C or colder. It may have been pre-vfo days, and could have been the crystal which I had not considered until Fred mentioned it.
