Re: [IRCA] WWFD 820 Becomes First All-Digital AM Station

Is it?


Since they have no analog, there's no reason for them to use the hybrid mode of IBOC which has both analog and digital.  That is what causes the interference to adjacent chanbnels and limits the IBOC coverage a bit.


If they use the all digital mode, there are  different expectations for interference and coverage amd we'll have to re-analyze things.


But I'm unaware as to whether all digital IBOC has FCC approval.

It's not WWFD 820; it's "WWFD 800--810--820--830--840"
