Vacuum tubes on the summit by OK2BWB

 est for use on SOTA activation:

Just did a first test hike with Hejkalset in my old comfortable metal frame backpack with a large load capacity (since a vacuum in electron tubes weighs almost nothing). I spent two hours on the trails with no real difficulties and ended up with four nice casual QSO’s.

Finally, I spent more than three beautiful hours on a trip that was supposed to take a few tens of minutes.
