The results of posting without first monitoring.
Mt Tom used to have a different ID & freqs. I believe that was changed during an upgrade and the old site was eventually shut down. There were 2 for a short while but the second one shut down a while ago (perhaps years).
The only active site in Berkshire Cty (Holyoke is in Hampshire Cty) is Mt Greylock. The schedule for the Western MA buildout was submitted to the FCC and I posted it on ScanCapeCod (FYI, very soon to be ScanNewEngland)
There are no sites as of now that are 3 digit designators (site 101, 102, etc).
