Dear Emil,
That’s an interesting and exiting twist to this question.
We have never had any visitor (old or young) telling us that they have ”heard” the 17200Hz.
One should know that the machine, when running, is creating lots of loud noice in the transmitter hall, mainly coming from the air cooling fan, used to cool and blow out any arcs on the large contactors for modulation of the carrier wave. So to pick up any high frequency sound it that environment would be rather difficult.
One could also wonder why many visiting children, gets restless and sad during the transmitter startup. Could that be the high frequency that they are picking up?
Most likely not. I beleive they just get bored and wants to go out and play on our new playground 😉
