This is NOT Video

Some folks who may be running narrow filters and don't have an SDR to see 'the bigger picture' might be thinking any ole carrier on 49.750 Mhz is some video carrier of a DX location.

Be warned there are systems currently using 49.75 for some sort of signaling.

I suggest that if you are stuck with a old school radio with narrow filtering and no visual band scope type of view, that you pan up and down the band looking for additional carriers.
