@Jeff: if W242AA is relaying the HD2 audio of WGBH, then by definition 
no HD carriers can be "passed through" because WGBH HD signal is being 
decoded to audio and then fed into an audio input of W242AA's 
transmitter.  (possibly with an audio processor inbetween)

@Eli: I would suspect that you were getting digital carriers from either 
adjacent-channel WSRS out of Worcester or co-channel WEII out of Dennis. 
  Both have pretty monster signals that would ordinarily come in fairly 
well in Kendall Square if it weren't for W242AA.  It's entirely possible 
for a digital signal to start to overlay an analog-only one; I've seen 
it happen...the radio starts on the analog station and then suddenly 
blends to the digital one.

Or maybe WGBH really did drop a dime on a new HD Exporter for W242AA. 
But if they did, they never notified the FCC about it and, AFAIK, FM 
translators still require digital notification.
