Hi KDKraze,
You could'a called the station to find out what was going on...
WUVN - DT 1, 2, & 3 are Univision, Univision, and Telefutura signals. They are on many cable companies around the states of CT & MA. As pointed out: LATV is the fourth program stream. WUVN currently has only two dishes to work with that are located on top of 1 Constitution Plaza, a 20 story building.
Univision Networks embarked upon a project to upgrade their signal and processing through the birds. What was thought to take a day or so wound up taking almost 4 weeks. During those weeks of installation, calibrating, and trouble shooting Univision made its signals also available on its back-up (sun-outage) bird. Thus, the to-air signal for the Univision networks was most reliable that way. To get those signals the dish that was looking at LATV had to be temporarily moved while Univision was going through it's new set-up. Because LATV is both relatively new on the WUVN digital signal and LATV doesn't have cable carriage yet the impact was thought to be minimal.
Currently LATV is now on the fourth program stream with no anticipated interuptions in the future.
As far as the "free TV" comment goes: You may want to take a look at what's out there and compare it to a basic cable package. For the one time cost of an antenna (maybe $100), Rotator ($80), and some poles, etc. (maybe another $100), there is a whole world out there. I can get almost two dozen program streams at home. Toss in a couple of low power analog (yup, most are still around) it is an excellent value with excellent reliability.
