“This power bank keep alive is exactly what I've been after for a long time. As a radio ham, I need to know what radio propigation is like from time to time. So I use a small transmitter called WSPRlite. This transmits a signal for a minute every so often then goes quiescent for a while, then another minute transmitting. Anyway, it's during the quiescent period that the powerbank switches itself off and ideally I need the whole package to keep running for days on end - so I can get an overall idea of what propigation is doing. The KeepAlive fits the bill perfectly and it's been running with the transmitter and powerbank for the last two days and nights. The map image attached is the stations that have heard my transmissions.”
