AM-band HD Radio bit rate

[Bob Nelson]

>>WNNW sounds very tinny without HD 

Speaking of WNNW "Power 800", last night I drove through N. Reading, Reading, Wakefield, and Lynnfield (Rt 28, Rt 128) and
was able to get the  Newton NH-based translator at 92.1 through all before other stations took over. There was an ID at
2 a.m., first in English then Spanish but I'm not sure if they gave the actual call letters (W221CH) or not (maybe in
Spanish?) but the signal wasn't totally clear so I'm not sure.
Incidentally the website for "Power 800" doesn't mention 92.1 yet and it's billed as "Boston's Only Hispanic Radio
Station". Well, I guess they serve part of the Boston area at least (and 800 is quite strong) but what about WKOX and
WXKS?
