Probably some microprocessor based device that has a 4mhz crystal clock oscillator. It will be interesting to see what make and model it is.
That situation reminds me about the guys that tried to run a 440 repeater with an ACC controller and a 146.76 simplex remote base on it (to this day 146.76 is still a simplex channel in the Los Angeles basin). The ACC has a 3.58mhz color burst crystal to run the touchtone decoders. Actually it's a 3,579,545 Mhz oscillator. Multiply that times 41 and see where it lands. The ACC ended up going somewhere else and a Cactus controller took its place (no microprocessors at all).
