Playing with a brick

I wasn't much interested in SKN last evening, but I certainly had CW on my mind. I want to on-off key this microwave brick I got on ebay. 108 Mhz in (thats what the Si570 synth and is doing, and I don't have a 12 dB attenuator for it in size "small.") gives 10368 at 9dBm out. Way too powerful, swamped poor Junior. ;)

I found I could alter the reference frequency a bit, and thusly shift the output frequency, but output power dropped off, the signal wasn't so clean... It just wasn't too "happy" in a way I can seem to quantify.

But yes, I want to find a way to key it. A pin diode switch?
