RE: [Elecraft] OT - Solar panel output

2008-03-19 Thread dolfindon
Hi Actually 33 watts is more than enough to power a QRP K2. You only transmit about 25 % of the time and receive the rest so running a K2 at 10 watts will only require about 15 watts to keep the battery charged. For a 100 watt K2 you will need about 75 watts of panels and about a 35 amp hour
