Suddenly poor reception of cbs 58

[wysiwyg]

I've been getting a lot of signal dropouts  from 58 and its subchannels the past few days. I've tried rotating the antenna but it doesn't help.  Channels 12 and 49, which are supposedly located on the same tower, still comes in great. Have they changed signal strength?

I thought ch. 49 is on ch. 58's tower since they are both o&o by Weigel.
