I think Jos's rig is magnificent. He is getting the high voltage for the tubes from a cheap (3 Euros!) 12 Volt to 120 Volt DC/DC inverter that he picked up via e-bay. (I think you can see the inverter board to the left of the headphone jack.) He runs it from a 12 volt gel cell. The little battery is for the filaments. He gets about 700 mw out, and had a very solid 15 minute QSO with Jim, W1PID yesterday. FB Jos!More Sputnik news (with some audio from the original) tomorrow.
DSW to all!

That's really cool. To me it harkens back to those old AM BC transmitters with the big tubes behind a pane of glass.
