Hello Channel 83:
As of this morning I can pickup WSBK, WLVI and WHDH, with somewhat less signal strength than before the changeover.
WSBE stopped broadcasting over the air September 20th according to their website. Their website said as of Friday that they will begin transmitting from RF2 on October 31st, and also mention that WLNE and WJAR will changeover to their new RF channels on that date too. However, both WLNE and WJAR announced that they will changeover on Tuesday, October 22nd on their websites as well as their over the air onscreen announcements.
And like you, WGBH 2.1. WGBX 44.1, and WFXZ 24.1 are all too weak - it was announced on this board that WGBH was approved of a power increase but according to WGBH that may not occur until January 2020.
And yes, since sometime last month, WUTF and WNEU are too weak to produce any type of signal. I think that its due to the transmitter work at the CBS facility and the Cabot St towers in Needham for all the Boston stations on the transmitter sites. We'll have to see how good - or bad - the transition will be when WLNE, WJAR and WSBE changeover.
