4S2P power pack with 18650

Having a few leftover 18650 batteries (about … too many), I decided to put them to use instead of recycling them, so let’s build a power pack. DISCLAIMER don’t do this unless you know what you’re doing. I’m not responsible for anything you might do wrong.

Started up JTDX and only seeing a few stations reported on each time block (normally it’s at least 20-30 on each pass). Looked up, antenna cable was not connected to the balun. Yes, digimodes are that good πŸ˜€

Plugged in the Raspberry Pi with the SDR Uno for some WSPR listening today. http://wspr.rocks/ is very nice and fast.
