When WRGB changed its digital broadcast from its transitional channel (39) to its final one (6), many people lost their ability to receive it. That's partly because low VHF channels are more susceptible to interference from common sources than high VHF and UHF channels are and partly because most readily-available antennas (often marketed as "digital" or "HDTV" antennas; both meaningless terms) are suitable only for UHF and maybe high VHF, and then only at close range. Channel 6 requires a physically large antenna.
Although WRGB has been installing UHF repeaters when and where they can, one partial solution was to duplicate their primary channel on 45.3 (real channel 43) which they also own. It's not HD but it's flagged as 16:9 so it fills a wide screen properly.
WRGB installed a translator on real channel 19 on Jiminy Peak in Hancock, MA for the Berkshires to get 45-1, 2 & 3, however they transmitter quit after a little over a week and it doesn't look like it's goona be fixed ever. Apparently Chief Fred is gone and it is now an extremely low priority. While we get real Channel 6 great here with a 14 foot antenna, 45 is impossible even with the best UHF antenna hence the reason for the translator. Seems like all the locals are broke for whatever reason.
