I have three ATSC tuners, two of which are on HD recording cards, and all three of which use the same antenna feed. I have good reception most of the time, but last night my MyHD (MPD-100) card failed to record KTVT-DT. I checked to see why, and I found it could not receive KTVT-DT at all! I checked the other two tuners, and they were picking it up fine. Only one of them provides a signal strength estimate (based on bit error rate), and that indicated 83%/23.0 dB. The dB value is a bit low, but KDFI-DT comes in at 58%/15.8 dB on that tuner, while the MyHD card could receive it fine.
Has anyone else noticed a change in KTVT-DT's broadcast, or an increase in noise that affects your reception?
