am transmitter

[Einar72]

Best one I ever annoyed my neighbors with back in '68 was the one in the late-50's Sylvania Transistor Hobby Circuits Manual (not the one from the mid-50's). Had a decent modulation level and no "chirp" off to one side of the carrier. Could also try the phono oscillator circuit from a Philco "Beam-O-Lite" console, or the "EXT MOD" input on any old tube signal generator!

But speaking of annoying the neighbors...I remember devices that you could buy and there were plans in all DIY electronics magazines (Anyone remember Radio TV Experimenter magazine) for a small tone modulated transmitter that you could tune to a TV channel (Back when almost all tv was over the air) and as described "interrupt" the picture.

Just yesterday, I tiried to work up the nerve to ask for a Senior Menu item at Denny's! Only been 55 for a month now. I used to ride my bike for 3-4 miles each way to the only drugstore I could find Radio-TV Experimenter at!
