Fixed! Eton Microlink FR160 radio. Revived NiMH battery, cleaned corrosion off the PCB and resoldered a couple things. Spray silicone grease got sliding switch and volume pot working.
This lived in our grab bag for the liferaft, as I deemed it potentially useful due to having a radio receiver, flashlight and USB-A 5V 0.5A charging output powered by a hand cranked three phase generator with rectifier. And a far too small solar panel.
When a #generator is running connected to the power grid, it is also called that the machine is running online, which simply means it is running synchronized to the grid.
Or should it be on-line or on line, which is the correct spelling?
