It's quite convoluted, and I've been away for a week, so I am not sure what the status is, as of tonight.
However, one of the two main transmission lines at Cabot had an internal failure that caused a two line sections to overheat and fail.
Approx 300 feet up. Residual damage (smoke) was found as high as 600 feet. Because the two lines drive 1/2 wave elements on the antenna, the antenna is only giving
half of the gain, and no circularity in power.
To reduce the amount of RF in the system overall, WFXT moved to their Cedar Backup. WCVB did too, but may have switched back. I know the signal from Cedar St was giving us major problems.
