It was -6C on the summit of Ben Cleuch today and I reckon with the windchill it was -10C or just colder. My camera (Canon using 2xAA NiMH) doesn’t like the cold but I kept it in my jacket for 1.5hrs before using it and it seemed happy. I had 2x LiPo with me. One was partially used from last weekend and the other unused since charging 2 weeks ago. That was saying 12.2V on the 817 display which is the same as at 20C. The 817 LCD display was sluggish at updating but not surprising given the temp. My Icom IC-80AD has a LiPo cell and is not rated to work below 0.5C. I couldn’t get it to switch to high power, it stayed on low. Now it has warmed up it will select high power. I don’t know if this is deliberate or it was too cold for me to press the buttons correctly.

My CW is bad at 20C, at -10C it is very poor too! But I managed a nice QSO with DJ5KZ before it was too cold to continue. I’d already had 27 SSB QSOs and 1hr30 on the summit was enough at that temperature.
