Interesting design. What is the approximate power output of this transmitter?

"Put together " means that you designed it or just assmbled one? Sorry non-native, you know.

 

it was a kit, assembled at a qrp hamfest. works pretty good for only 2 transistors and a 9 volt battery. I have designed and built a few, but none with the output of this one at only 9 volts.
