KBOP (Ch 20) Signal

[BoardReader]

Hey folks, I could use a little help here. It seems like something odd is going on with KBOP channel 20's signal the last few days and today we started taking some viewer calls on 20.4 complaining of bad reception. I'm told transmitter readings are normal so I'm not sure if there is some interference or what. Is anyone seeing anything unusual on 20 in the DFW area? Thanks.

The strong tropo over the past few days when the warmup occurred played havoc with nearly all of the 15 kW signals from Cedar Hill. Co-channel and adjacent-channel interference obliterated them during the evening, night and into the early morning. Even some of the full-power facilities were getting hammered like KDTN and KTXD. At my location, K31GL is generally the first to vanish during these weather events. Fog is also a good indicator of similar weather events affecting the ability to receive weaker signals.

Thanks Bob, that clearly explains it.
