Thanks for the info Mike. For me, I'm pointing to the Dublin grade for Sutro; pretty much 315 deg (dead-on NW). For Loma Preida, I'm pointing about 230 deg (nearly 90 deg south from my UHF CM3023). I was on the phone with Chris around 5pm and we both noticed break-upson KNTV-DT. I kept checking back later (I fell asleep before Leno) during Frazier, etc. and saw no break-ups. We suspecting they're adjusting their broadcasting power as a function of content/time.
I had the KGO truck out on Wens. and they looked at the Sac stations from my house. No NBC, but ABC from Sac looks good. I was mainly interested in NBC from there to hedge my bets against issues with KNTV-DT. They looked at KNTV analog and it was around -50dB compared to -10dB of KGO from Sutro.
Does anyone know how to get in touch with the engineers there? I tried the web, but quickly got bogged down in msnbc.com junk. With what's on the horizon this fall, I'm very excited and a bit worried about p.q from that station.
On a side note, isn't "signal strength" that a particular STB gives, just an arbitrarily scaled number (presumable between 0-100) that is a function of error-correction scheme, etc. Too bad it can't give an absolute dB number of the incoming signal. I say this because when I used R8dr's pre-production Zenith STB, all the Sutro stations were at 2 green bars (red and yellow fully lite). I replace the Zenith with a new Samsung (sirt150) and it showed these at 3 bars (using the lower broadcast graphic) out of 10 using the same antenna setup (Radio Shack DBT mounted on the roof). Changing to the CM 3023 and CM7777, improved the reading to 8 and sometimes 9 bars. On the upper tickmark scale, 8-9 bars shows as 1 tick above middle. KNTV-Dt shows 1 tick below middle.
