Over the air television - in and out fuzzies???

There are many issues. Some stations try to cram in one too many sub stations

As someone said Solar Flares,, Actually several solar issues Spaceweather.com for more on that or google Ham Nation and watch Dr. T's segments.

And someimes you are "on the edge" in teh RV replacing ye old wall switch with a Sensar Pro (Winegard antennas) may help.. if you have a BOMB as I do. the Senser pro goes between teh Matrix Switch (BOMB) and the antenna.. Works, and I mean WORKS!!! many added features.
