The transmitter and coupler behaved with a 12 hour hard key down at around 1Kw input.
Temp temp readings using a hand held laser guided meter on the main coupling block core ferrite showed it sitting at 34F (1 or 2C) - Mica G2/G3 capacitors at around 18F/20F - this is a good result and tuning was stable from switch on till off. Ambient air temp around 0F/-20C with a 10mph wind.
Thanks for all the reports - much appreciated. Ill take a look at some of the snaps. I may do another run tonight as conditions are still fair/poor with too many Protons hanging around but it is cooling off up here slowly
