Ham radio field day at Harris hill in Horseheads NY, June 27th 2009. I made a man powered power sourse to power a dual band Kenwood radio. The object being, making contacts on 2m to qualify for field day points for human powered radio transmission. It’s made from an old Bicycle, a salvaged alternator from an old GM school bus and a small 12v emergency light battery to jump start the field in the alternator, without the jump start, the alternator will not produce any voltage. Once the field is energized, we disconnected the start battery. We had some issue when N2EUS keyed up the radio on low power {5w} The load created increased the effort hand cranking the bike. Our main object was to prove we could do it with an alternator. We made two very clear contacts through the repeater. My next one will be made using a copier motor.
