As an EA viewer, I must say sorry, but I could care less about locals on the WA. I hope the new satellite at 61.5 would allow more spotbeam room for more HD locals and perhaps sub channels as well.
As for locals in SD only in Boston it's every affiliate that's not one of the big four networks. That's WGBH (PBS), WMUR (ABC out of NH), WENH (PBS out of NH), WUNI (Univision), WSBK (MNTV), WGBX (PBS), WBIN (Independent out of NH) WLVI (The CW), WNEU (Telemundo), WMFP (Plum), WTUF (Telefutra), and WBPX (Ion). That doesn't include sub channels. There are many sub channels here in the city. Thanks to OTA I do get virtually all offerings.
