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
2025-05-14 22:22:30n8dmt@mastodon.radio21Success!#HamChallenge HC36S Operate your station from battery power for a day. GoalZero Escape150 powered my IC-705 station for the day. 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.radio31Success!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

2025-08-17 15:31:04g7kse@mastodon.radio33Success!Week 36 of is about operating from a battery. In my case it was 2x18650 batteries for one rig and a 1000mAh LiPo battery for 2 others. I powered the Mountain Topper MTR5B, (tr)uSDX from the LiPo and the zBitx from the 18650's for about 3 hours. Chased a few lighthouses and POTA stations. So I'm calling it a win HC36S.Today, the bands aren't working for me. So I don't think I'll manage anymore today
2025-08-25 10:31:13ian@mastodon.radio33Success!And an early submission for 52-week #HamChallenge week 36, because I am also operating my station entirely on battery power today.You can read all about that, as well as the full story behind the previous three weeks, on the blog: https://ianrenton.com/blog/52-week-ham-radio-challenge-roundup-weeks-33-36/HC36S
2025-09-01 14:00:59mcdanlj@social.makerforums.info15Success!I operate entirely from battery most days, and never have "range anxiety" — but then I usually operate near or at QRP out in a park. But also, even when I bring the 100W radio out into the park I have more than enough power for a day of operation without stress.I have internal batteries in one rig, several sizes of LiFePO4, a USB-C PD power bank with "trigger boards" for 12V and 15V, mains chargers, and a 100W portable folding solar panel with charge controller. The diversity here is driven not

2025-09-07 11:01:59bgarfoot@kind.social17Success!Week 36 of the is a fairly easy HC36S for me. My entire rig is in a go box for portable operations, with a LiTime 12AH LiFePo battery and a West Mountain Radio Epic PWRGate handling power distribution. Add in a JankaPOTAmus Gateway laptop that runs on 12V, and my entire station is battery operated.

2025-09-14 19:39:05df5go@radiosocial.de19Working on it...Week 36: Operate your whole station from battery power for one day – I mainly operate portable and use a variety of LiFePo4 and lead-acity batteries. I seldom operate for a whole day but with a combined capacity of 23 Ah I could do this with the QRP rig.I should at least try to work with my home station using the batteries only for a couple of hours. #HamChallenge #HC36 #hamradio #amateurradio #Amateurfunk
