On the facebook page for WJIB listeners Bob Bittner had mentioned WJIB was off temporarily--it had to do with work on the antenna, which WNTN 1550 will soon diplex from. Someone commented that this week, WNTN moved to new studios in Needham.
As you'll see here they had a CP to have the COL change to Cambridge and broadcast from the WJIB tower
Daytime power 750 watts, nighttime 3 watts (Previously 10kW, then 3 at night)
The link above will show you coverage maps of the new signal and clicking on the GPS co-ordinates shows where the tower is, off Concord Ave in Cambridge.
And this link shows you the info for the new WJIB simulcast on 101.3, coming soon. Originally from Freeport ME
