Yes, I’m in Somerville just a few miles away and it’s very weak here. I used to try to listen sometimes when it was “Big 105.3” playing satellite or voice tracked oldies.
Westwood one was entirely satellite fed... but if were going to get nitpicky, many of those formats are voicetracked.. most times within the hour the track airs (Ive seen one of their network studios HQ)
Though, the morning guy on Classic hits Oldies is Bruce Palmer whos at the Pike in Worcester, so it probably is voicetracked. Could be delivered by Storq, the system which has another computer at the station where all the music resides, the jock VT's from wherever they are and it gets pushed to the station directly
