Then that brings me to ask what is the F1 Information channel on 796.528125 ? What system is that channel from? I can listen to it all day with no problem on my PSR500. I don't think it's digital. I have it as a conventional with a dcs of 271.

I'm wondering if there are more 700 type freqs like this being used but I haven't set up a sweeper yet.
