I'm hearing a weather station on the frequency for a local repeater.

Still unlicensed.

When I'm driving to/from work, I'll be listening to some guys talking on the local repeater, but when I get to one part of the highway that's elevated to clear some train tracks, I can hear a weather station being broadcast on that frequency. The frequency in question is 146.940, and I can't find any weather repeaters in Repeaterbook for over 300 miles operating on that freq.

Is someone locally rebroadcasting the weather station onto ham Freqs? From what I can tell, the broadcast is the local weather channel which would be 162.550.

I can provide location info, but I'm just really curious about this.
