Received several emails with Q's.How do you activate the light generator  and key CW at the same time?
A. Tricky, kind of like rubbing your stomach in a circle and patting your head at the same time. Or perhaps flying 4 ship wing tip and with the stick in one hand and changing radio freq with the other when channelization circuits fail.       But still working on the coordination.
The flash light provides aprox 6 VAC and had to be rectified and I use a 49,000 uf cap for a filter and it also serves as "storage".
Radio circuit is from a ePay Radiokit and is a basic QRP circuit based on the original QRP "Pixie". Price on ePay is 6 to 11 bucks for board and parts. Cheap entertainment.  Something different. During Field Day you can go outside the 1000 foot circle and provide an extra contact.
