Phil,
Thanks for the info. I'll keep an ear on the other two locals to see if and when they resume IBOCcasting. A quick check just now -- WHSR 980 and WWNN 1470 -- shows that has not yet happened.
WSBR's was off for a couple weeks. Since their IBOC walks on a station I check regularly, I probably caught that at the beginning. Only when I noticed their IBOC was off did I tune in the other two, so they may have gone off sooner. Since all three stations are licensed to the same company and are within a few miles of each other, adjustments might be done on all three, one at a time. This could explain why the other two are still off, or it could be they needed more work to correct. If your assessment of the outage is the case, I guess I can expect those two will be back shortly too...groan.
I don't know if the WSBR digital audio was getting out before -- who does, there are no radios -- but the noise certainly was there. I detect no improvement in the quality of the noise following the interruption for adjustments. Maybe I should report that to them. Think they would appreciate my diligence?
One thing I did today, was check the audible limits of the noise. The top to bottom frequency range for audible noise from the station on 740, was 758-722. So they wipe 750 and 730, and add noise to 760 and 720. So there is IBOC: 'In Band', all over it in fact, and I guess it's 'On Channel', if you include enough channels.
For the record, I have so far not received a response to the question I mentioned sending to the GM of WSBR, but it has been only a couple days.
