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



Ah, I understand now. 

I suppose it makes sense as a technical test. Washington, DC is âworst caseâ scenario in terms of multi path, signal obstructions, etc. If it performs well there, it should do even better in most locations. 

We have a client in DC and get there often. Iâm supposed to be there for two weeks in August. Iâll be âdriving the signalâ myself.

The whole reason they're using the WWFD AM signal for this is because it's not doing anything, business-wise, for them. Most Gamut listeners are tuned into the HD2s or the analog FM translators that relay them, or are on the stream.
