Reviewing my logs actually it looks like it may sometimes start in middle of night. If I look at noise floor on the sector, it degrades starting early as midnight, gets worst early morning like 5-6am and then goes back to normal around 8 or 9. Thats what the past few nights show. The only time I actually get stations dropping offline is in the 6-9 timeframe. Yes does happen on weekends a well. Some kind of atmospheric condition allowing me to see a signal I usually cant? This tower's been up for 2 years and never seen anything like this before.
