WSRO 650 all digital Dec 1

Fybush has had the engineer from 820 on his podcast once or twice. It was fascinating listening.

How many stations on the AM band are now fully HD? Would the same tuner that picks up HD subchannels on FM be needed to hear this?

It’s interesting that this all digital WSRO has come along after all the hybrid mode stations in the area have given up on HD completely.

This is the list of stations I came up with

800 WCCM Lawrence, MA
1260 WBIX Boston, MA

I think 800 was WNNW (Spanish) by when it ran HD. It switched calls in 2002.

1260 was WMKI (Radio Disney) during its HD years. If the HD carrier may have been kept on briefly after it was sold and changed calls and formats to WBIX, it was only for a very short transitional time.

As long as the HD tuner ALSO has AM HD, it would hear 650 WSRO in digital, within range. Most, but not all, HD FM radios also have HD on the AM (though I've seen some, mostly HD FM portables, that had no AM band at all).

AM never had HD subchannels like FM (not enough bandwidth), but any AM HD radio that heard the stations that (used to) broadcast in AM combined digital and analog in HD will hear 650 WSRO in digital (within range).
 
caught WSRO this morning on 93 from Andover down into Stoneham (before I got sick of the music)

Good signal (hey its digital, it is either their or it is not....)

The choice of music aside, it sounded pretty good.
 
(USA) FM HD signals are (IIRC) 1% or 10% of the analog FM carrier power.

AFAIK, the few all digital HD signals in the AM band operate at the same power levels as when they were analog AM, any evidence this is causing interference with analog AM or vice versa (most likely at night)?

Here, when 1190 AM+HD was Radio Disney, at night, WOIA 1200 AM would interfere with the upper sideband of the 1190 HD signal, causing my Sony XDR-S3HD HD radio to continually switch between HD and AM.

Did you mean WOAI in San Antonio?

Sometimes, WSM AM 650 is fairly clear/intelligible here (KC area) at night, much chance that WSM will interfere with the WSRO HD signal at 650kHz?

This might answer your question https://lmgtfy.app/?q=WSRO+650+coverage+map

not likely a chance in hell, if theyre on proper night facilities./. and even if they were using day facilities at night, id doubt it.

What music format are they running? Saw online that it might be "Jazz Standards", or is it something else?

It is jazz standards. If you’re in different parts of the greater Boston area, you can hear it simulcast in analog on its FM translator on 102.1 in Framingham, and on co-owned 1410 AM WZBR Dedham and its FM translator on 98.1 in Medford.

I have a Sangean HDR-16 which can decode full AM digital. I bought this radio a few years ago, and, based on what I could see, the ability to decode full digital as well as "HD subchannels" was designed into the product.

So, the MA3 signal definitely gets out further than the hybrid HD, right? Andover should be in the 0.5-2.0 mV/m department, leaning toward 1.7, right? This helps me feel more confident about the coming of All-Digital AM for sure.

It sounds really great on my am car radio.

In the MA3 all digital mode, there is a HD-2 BUT most HD radios cannot decode it..later models will.
