A week ago, I went to check my OTA signal strength and noticed something odd. 2 of my OTA channels (previously 95-100%) now read between 55-65%. My other OTA channels read as they did when I enabled OTA on my HR20. Anyone else notice any OTA signal strength abnormalities? In case you're in the Sacramento, CA DMA the 2 channels in question are KCRA and KOVR.
