I just ran a scan, and KPBI showed up, but is very pixellated and sometimes drops completely off, which is exactly the way KNWA has been behaving since June. Also, the scan that picked up KPBI for the first time managed to lose KNWA. Such is the signal quality the last few months. I'll try another scan this evening, which I'm sure will pick up both of them, albeit at marginal levels. Hopefully losing foliage this fall will bring them back to watchable status, although KNWA was very strong last summer.
Wow! Time for an update. (4:20 PM) After doing the initial scan on the Polaroid, and getting KPBI in the channel list, I turned off the Polaroid. Upon turning it back on, it had lost ALL the channels in it's memory, both DTV and analog. It defaulted to channel 2. I did another scan, and got everything again, including KPBI, but still no KNWA. That's when I noticed the tuner was rapidly cycling between "retrieving data' and 'no signal' while tuned to KPBI. It would then lock up and have to be turned off, only to have lost it's memory again. I tried a new scan on my Dish 211 receiver, and it promptly found KPBI, and even showed around 70% signal strength, but no KNWA. When I tried to watch KPBI, the 211 locked up with a black screen and had to be reset by holding in the front panel power button. I then did a scan with my Dish 622 DVR (In the same rack with the 211) and it found KPBI, with a very stable signal and is pixellation free. I then fired up the Digital Stream converter box, which has always been the go-to tuner to get signals the others can't. It gets a great stable picture, then the screen will go black. It will still show good signal strength, but then power cycles itself. Meanwhile, the Pioneer 5080HD takes about 10 seconds before it will lock on, but then gets KPBI rock solid.
So in summation, the Polaroid, the Dish 211, and the Digital Stream converter all have major problems with KPBI's signal. The Pioneer and the Dish 622 do not, and get a strong stable signal, with no pixellation. There has to be something very strange with their data stream. I'm going to climb behind the rack and reinstall my attenuator and see if that helps, but I'm not hopeful. For three different tuners to lock up and have to be power cycled tells me something else is going on.
Update as of 5:20 PM. The Digital Stream converter now seems fine with KPBI, and has a very stable picture, although, like the Pioneer, it takes about 10 seconds or so to lock on. The Polaroid and the Dish 211 are still having problems. Is it possible they are still tweaking parameters and such?
