I have one of those 1K fiber optic widgets with screen and capture
capability.
I will try to fire it up and get you a close up view. No promises.

"All of the circuits shown are aimed at reasonable stability, but have relatively low output power. It is possible to bias many of these circuits higher to obtain outputs of up to perhaps 1/4 watt. However, thermal stability is often severely degraded, chirp is introduced if the oscillator is keyed, and the user stands a chance of damaging the crystal from excessive rf current. It is not recommended that a single oscillator stage be used as a simple transmitter. The addition of an amplifier is so straightforward, and the system efficiency is so much better, that the minimal simplicity is not of value."That may be true, but the Mighty Mite is for learning and getting our feet wet. Still it may be interesting to point the above out or talk about it.
Hi Bill,Wow –so cool! I was impressed with not only his M^3 but the homebrew key and sending with his left hand.It would be nice for Kai to send us his details for the key. It looked like a hacksaw blade sandwiched between some plywood blocks of wood and some sort of plastic tuning knob from a defunct transistor radio as the key knob. Now that is what I call homebrew –elegant and it works well!73’sPete N6QW
