Yesterday I was on HB/ZH-009. The signals were extremely weak like on a beverage. I used a 40 meter dipol. Battery and output were okay. I never used my IC-735 in such severe coldness.
Does anyone have experience with the receiver of a IC-735 in coldness?
A battery’s effective capacity can drop to 10% in extreme winter conditions. (You may have noticed it starting your car!) Operating discharges it thus the terminal voltage drops especially under loaded conditions. No wonder if the built in regulators of the RIG cannot handle the extreme voltage swings perfectly and the tone becomes somewhat (?) chirpy.
But who cares it? A somewhat chirpy tone is a must in the final stage of an activation as it were waste of energy taking home even a single electron left in your battery! This is the bouquet of SOTA! And what is more, an activator’s (often weak but) chirpy tone distinguishes itself in the QRM of chasers!
Unfortunately I missed you. Maybe next time I can QSO you!

I’m inclined to think that you take back the same number of electrons that you took up.
I have a feeling that you will have radiated some photons somewhere… out of the heatsink on the radio and hopefully as a cloud of wave/particle dualities from the antenna!
Of course from the aspect of chemistry and electricity you are absolutely right! I intended to mean with my technically objectable symbolic expression that the nicest finish of a successful activation is returning with a totally discharged battery demonstrating that the activator made his best reaching the possible extremity, he established as many contacts as his battery permitted. We all made best use of the activator’s effort, crating a nice pile-up for him ending in a chirpy tone, finally unexpectedly interrupted transmission… Don’t you agree?
ISTR that Feynman postulated that there might only be one electron in the Universe and it calls in on everyone; rather like Father Christmas but without the good/bad exclusion principle (or was that Pauli?).
It should be lighter. To a first approximation, and assuming (to choose round figures) a battery of precisely 12v and 10Ah, your equipment should lose (according to Einstein’s famous equation) 4.8 picograms in weight.
Yes, 4.8 picograms sounds about right for the special case of such a battery, but only when it is assumed to be within an inertial frame of reference. Taking into consideration the acceleration of the battery in a necessarily non-inertial system (due to the diurnal rotation of the earth, orbital motion within the solar system, galactic rotation, etc), we would have to turn to general relatitivy theory for a more accurate value. At this time of year we must also take into consideration the probability of anomalous effects produced by Red-Shift Reindeer moving through the battery’s frame of reference at a velocity reputed to be approaching the speed of light.
