Channel 58 WDJT signal strength down

[beeper]

On May 18th I noticed that channel 58 signal strength has dropped considerably. No other channels are affected.
It's almost as low a signal strength as low power channel 63 (WYTU) and I'm about 8 miles from the tower farm.
Every other channel shows maximum signal strength.

Not a problem for me, just curious. Anyone know why, or noticed the same thing?

EDIT: Whatever they were doing is now fixed. Signal strength back to normal level. 05/30/2011
