I was doing a fine tune scan on my PRO-164, and I heard a bit of a Christmas Play and all (A Christmas Snow as it's called), and... Well that's odd I think. It's a constant transmission and -sounds- like an FM Broadcast station, but the problem? The frequency. This despite sounding like a '107.5' or whatever station(and now telling me to visit the website on my screen, being a 'special movie presentation....') On 487.7375MHz... Any idea what this is?
