Yes. I have one as well, a "Talking House" transmitter. It works very well for me. The project is mainly for the exercise, but also as an add on for one of the radios that I intend to gift to one of my daughters for Christmas. I had assumed it was a phono jack because one of the push button oscillator/pad combinations (the one next to the on/off switch) is marked as "phono."
