10m Wispy Tx running overnight

The Wispy beacon Tx is set up to air via my ATU on the main station antenna, Toshiba laptop providing the audio drive WSPR signal at a 50% Tx cycle.

Its running from a 12v 7Ahr SLAB. As it uses pretty much the same current, and runs at the same temperature, regardless of whether its actually on Tx at the time or not, I am going to put it to 80% Tx overnight, and hope that at some point, perhaps morning grey-line, some propagation occurs that at least gets a spot to somewhere!
