Could this be for time synchronization?
Cheap alarm clocks just use the AC power as a known good oscillator.
What if the Buzzer were simply a wireless version of this? (Instead of exotic atomic clocks or OXCOs)
I’m not saying this is technically a really good idea, but as a cheap, fairly low-tech solution — why not ?
- winrid 3y agoIt's a neat idea but it's most likely just a marker so nobody else uses the frequency.
- crote 3y agoRussia has half a dozen WWVB-like shortwave radio time signals which would be far more suitable for that purpose.
- callalex 3y agoThere are already vastly better, available worldwide time sync radio signals that are fit for this purpose.
- eimrine 3y agoThe frequency is similar to those which are typically being used for that kind of task (Germany has shut down one of the biggest time sync radio station recently). For me it seems like a test for a wave pass, I mean if you want to send a message to some submarine via radio wave but have some hesitation whether the message reach the receiver, no callbacks are allowed for obvious reasons.
