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

Les, I think the point you miss here is that this station was a rimshot as an analog for the DC market and the HD signal won't hold in DC anyway

I think, as a DX'er and broadcaster.. HD would've been a bit more viable if
you could've gotten HD locking without needing such robust signals and find
a way to have it not interfere with other stations.  I've heard HD on AM,
I've heard DRM on Shortwave.... I used to listen to Radio Kuwait 15540kzh
english DRM.. and the thing needed a paint peeling banging barrel of brick
signal to lock and stay locked. It sounds great though.

I don't particularly find any use for it on AM, except the sound quality.
Where HD has... i dont wanna use the word flourished.. but done better is
on FM, and even moreso tv.. where you can offer sub/side channels. Many
broadcasters, with pretty decent financial success have put translators on
their HD channels (look at Saga communications) and offered formats that
may not make financial sense on full powered signals.

Where HD i think really works, is TV.. with the multiple specialist
channels.

Anyways, I digress. I don't dislike HD as much as some here do, but I'm
huge a fan of it in general.. it has proved interesting while FM DXing
though
