The unit broadcast on the Citizen’s Band and was first publicly flown at NARAM 2 in 1960. It was a simple multivibrator that put out a continuous tone which could be modulated by a sensor, but what to do with the wavering tone it sent back was left as an exercise for the reader 🙂 Stine still includes the schematic for this device in the current edition of the Handbook, although he finally admits to it being “a very old design.” Foxmitter Using the same basic encoding principle (and still broadcasting on the Citizens’ Band), Richard Fox designed the “Foxmitter” which was described in the May thru December ’69 issues of the old _Model Rocketry_ magazine. An improved version, the “Foxmitter-2” was detailed in the June ’70 thru Jan ’71 issues of that same journal.
