[PVRCNC] WUNC-DT update

[Guy Olinger]

I note that 12 Mhz bandwidth dual adjacent channel antennas are in the mix. I suppose that is what WRAL/WRAZ is running (48/49). I'd love to see the power combiner, or is there some kind of trickery for that?  Seen some lists that indicated WRAL running megawatt ERP.  That true?

Wellllllll they are very high gain antennas.  But -- Just My Humble opinion
- What were they doing for the past couple of years that prevented them from
having an decent antenna on the top like every other broadcaster??

This is probably the antenna they are using:

And yes as broadcasters, we do lower the power for the crews.  Most crews
carry RF detectors so they know when they are at their limit of RF exposure.

Crawling back into my hole...
