Just a clarification. While the Battery subclass is limited to 5W, the Alternative Power Bonus is not. We were running 100W on Battery for one of our stations using Solar Panels as the power source.
I also agree that the Battery subclass should allow more power. There would still be the QRP power multiplier to account for the power level. My club might be willing to go to all battery, but would not be willing to give up 13db. I'm for recognizing the additional effort to do an all battery FD with the Battery subclass. I don't think we should then penalize them by restricting the power they can use. The effort required for Battery is strongly related to the power level. If an organization wants to go to the additional effort to run 100W on battery for Field Day, they should be allowed to so so. Just have them get the normal multiplier for the level they run. -- Clark B. Wierda N8CBW
