WWFD 820 Becomes First All-Digital AM Station  View Printable Version 
Tuesday, July 17 2018

IRCA
Some of this I can answer even before interviewing Dave - the format is
called "The Gamut," which is a true "we play everything" variety mix
that goes back as far as the 1940s. It's been running on WWFD for the
last few years, as well as on HD2 subs of co-owned WTOP in Washington
and its FM relay out in Virginia.

It's important to note here that the format isn't especially important
to what's essentially a technical test. 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.

The idea here is to get a real-world sense of how the AM all-digital
mode works, and I expect a lot of engineers will be out this summer
driving the signal, taking measurements and learning how well their
theoretical predictions match reality. (I hope to join them at some
point!) I doubt there will be much promotion to general audiences,
though I'm sure they'll welcome any feedback they get.

Scott,

Thank you for this opportunity. Iâm interested in knowing what format WWFD currently runs, and if they plan to change or modify the format to fit the âAll Digitalâ operation.

Also, do they plan to promote the âAll Digitalâ format within the market? How are they going to promote it?

Any chance weâll see the âAll Digitalâ experiment expanded to FM within the DC market?

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

As a regular licensed mode of operation, no...which is exactly why Hubbard and the HD Radio folks are conducting this test under experimental authority.

I'm going to be interviewing WWFD's Dave Kolesar this evening for a new episode of my "Top of the Tower" podcast, to be released tomorrow. If anyone on the list has questions about the purpose of the test or the technology behind it, hit me up and I'll ask him!

Letâs hope so.

I was unimpressed even with HD FM coverage. Too many drop outs.

Is 1500 in DC still iboc?
