Since January 14th of this year, I've been hearing the same tape loop day and night as posted earlier this year. It has been relentless with no break in transmission. There has been much speculation on what it was...even my email inquiry to the FCC resulted in a nice reply that this was Hudson. Today at 2130 UTC I happened to do my daily check and they are broadcasting a long repeated loop identifying as the "Springfield Armory National Historic Site". I knew it was too strong here to be Hudson!!! The Springfield Armory is located on the grounds of Springfield Technical Community College (STCC) on State St in Springfield (naturally!). STCC is actually located on the site of the original Springfield Armory grounds dating back to the Revolutionary War. Mystery solved!!!
{The loop which is quite lengthy, mentions 1710}
