However, they're half-way to being an 'I.C.' in that they in a 14 pin IC DIL profile! The waveform was more or less square, but with some ringing, albeit of no detriment.

Good to see yet another inventive take on pantry transmitters, which make nice and useful homebrew projects for little outlay. I must resist the urge to design a PCB for it, or it will be yet another diversion from a growing list of half-finished projects. Meanwhile, my Mini Mod continues to give good service.

It would be nice to hear from forum members who build this circuit, to learn of their experiences on how it performs.
