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?

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.

<<< Basically, as some of us know, if you can avoid static-crash nights, there is still a lot of DX to be heard in the heart of summer. This is especially true when talking about southerly targets enjoying greater length of darkness.
Not sure how the whole "DX season" thing got started. I suppose some parts of the country such as the Deep South and parts of the Midwest have nearly continuous thunderstorm activity. In the northeast and the northwest you can sometimes pick your spots for relatively noise free success.


Gary DeBock running Down Unders from OR and WA would be the West Coast version of your Cape Cod summer DX, Roy.

783 hasn't shown much here either lately. What is there is probably Spain / Syria instead of the usual Mauritania flamethrower.

Thanks Mark,


Your descriptions of summer trans-equatorial propagation on the Cape are always very interesting


Summer ocean coast DXing does seem to be increasingly popular here in the Northwest, where we plan to have 5 DXers for our annual Rockwork 4 ocean cliff extravaganza next month.

Although the distinctive site has a reputation for being a New Zealand-favoring venue, Tom and I both came away with a couple of western Australians (531 and 558) last year, plus, some low-powered Oz stations. Fiji, Tonga and Kiribati are also regulars. Early August seems to be prime time for the 9,000+ mile Western Australia path around sunrise.
