[BC] AM Interference

[Mike McCarthy]

It might be that the night time operation will occur when the analog 
sunsets.  At which point, most of the interference issues will be moot and 
actually might allow many more non-class A stations to ditch their DA 
arrays and go omni or to increase their night power. Some might even be 
able to offer night service for the first time. WHY...because the D/U 
ratios to the adjacent channels will all go out the window.  Especially on 
2nd and 3rd adjacent channels.  You could almost co-locate stations only 
two channels apart instead of the 4 channel spacing we have now.

I think THAT's where digital will shine in the eyes of the station owners. 
But only when everyone goes digital and back to 10KHZ primary occupied 
bandwidth.

I would be opposed to permitting new stations to come on as a result of the 
reduced D/U ratios if they would have to go DA or would have overlapped 
other stations if they were analog.  But it would be my guess that there 
would be a mad dash to the FCC to file 301's to eliminate DA's/increase 
power/get night service and might be a moot point.
