WWJT is on the air with content on 7.1, 7.2, 7.3 and 7.4. Apparently the signal is very weak. I have one tuner / antenna combination that can lock on it with frequent dropouts but most of my equipment can't even see it's there.
WWSI is on the air with two Spanish channels 62.1 and 62.2 on RF 49. This comes in strongly here. They've long had an application to move their broadcasting antenna to Waterford Works and it looks like they've finally done it. Other stations broadcasting from the same location are WNJS, WMCN and WACP.
