Except for one QSO, for which I had temporarily misplaced the power cable, and got a 667 mile TN–NY CW QSO on 17m using only the weaker internal batteries. So, all battery power, no recharging the whole time, and all but one off a single small battery.@hamchallenge

Not a lot of transmitting (busy with other things), but battery still more than half-full after 10 hours. Will use solar panels to recharge pack later (or tomorrow). This is a smaller/older lead acid system that travels well and no-worries if damaged or dies (again). Mod adding power poles was a good decision. Enables portable fun! #HamRadio
2025-05-19 01:20:31yo3gnd@mastodon.radio30Success!My usual setup involves a suitcase with 2 pcs 18Ah LFP4s in parallel with some 3D printed bulkhead connectors. The suitcase acts as a makeshift desk #HC36S. I don't operate much from home, so these 6 hours were a whole day operation.I was surprised only 3 DXpeds were active, but a fourth DX, the ITU HQ was lurking on 18MHz. #HC07S. Working 10+ DXCCs is rather easy in FT8 from Europe, when you're being chased in #pota #HC37s#hamchallenge
