At least you got 106.3 FM in Southington. Anywhere in downtown Springfield, MA? Forget it. I barely got any signal of it in the area of Amtrak/CT Rail/Greyhound. Even with my Walkman's LOCAL/DX switch on LOCAL (displays as "CITY"), it, along with 1/3 of the dial was stepped on by WMAS-FM 94.7 of Enfield/Springfield. It doesn't help that their short tower with plenty of power is close by, near the I-91/I-291 interchange.
I'm guessing that their Kool Oldies translator, 100.1 FM, must be on that same tower. The signal was stable and not being stepped on by WMAS-FM. The only other station not getting stepped on was WAQY-FM 102.1 (Rock 102) of Springfield.
