Thanks for the advice! I have a 100W framed panel and a GoalZero 50W battery bank, but the battery oscillated down in sub-freezing temperatures and cloudy days, I think. A dusting of snow finished it off. The WSPRlite requires manual time-set by powering up on the even minutes +/-1sec, so once off, it requires a manual restart, whether the battery come back up or not. The ZachTek boots to GSP time so that will work much better. Elevating the panel off the ground a foot or two and rubbing the panel with a silicone cloth should help reduce snow blockage. Finding open space will be the trick in well-forested Southern New Hampshire, USA. We have nearby power line clearings but in the vicinity of 133kV transmission lines is not the best location. If I can test the solar/battery there and find success, I can haul it all up a nearby low peak to set up on an obscure section of public lands on the slope. The plan is a 130ft MyAntennas 8010 Multiband end fed antenna, rigged as a sloper.
