I live about 20 miles west of Worcester in the famous Worcester Hills area. I enjoy fantastic DTV reception with a standard rooftop antenna and preamp. My reception is as follows:
From Boston: WGBH, WBZ, WCVB, WHDH, WSBK, WGBX, WLVI, WMFP
From Providence: WLNE, WJAR, WPRI, WSBE, WNAC, WPXQ
From Worcester/Marlborough: WUNI, WUTF
From Springfield: WWLP, WGGB, WGBY, Fox 6 (via WGGB's DTV signal), WSHM (via WFSB's DTV signal)
From Hartford/New Haven: WFSB,WTNH, WUVN, WEDH, WVIT, WTIC
From New London, CT: WHPX
From Adams, Mass: WCDC
My digital reception is almost as good as my analog reception was. After the transition, I am hoping to receive WFXT from Boston and WTXX from Waterbury, Connecticut, both of which I was able to receive via analog. Also, I am currently unable to receive any of the New Hampshire digitals, although I can receive WMUR fairly well on analog, and WENH used to come in well before WWLP started transmitting digitally on channel 11 several years back. Hopefully these may come in post transition as well.
All in all, if you add in possible subchannels, I can receive over 50 digital channels, which is up from the 38 I used to receive regularly. Most digital channels come in all the time as long as I aim my antenna in the proper direction. Some channels may fade in and out at times, especially the weaker Boston UHFs. However, Providence, Hartford and Springfield all come in perfect. My elevation of 920 feet, plus the fact that I am basically on a plateau with clear coverage to the south and west aids in my reception. I am slightly blocked to the north and I have a small slope to the east that occasionally causes the weaker Boston stations to fade out. But I am very happy with digital reception overall.
