Hi all, I'm new to the forum.
Moved up here a year ago and have been tinkering with OTA DTV. It's been fun, but frustrating. I put up an all channel (Radio Shack (I know)) antenna on a rotor with a preamp. Have good to very good reception of most Sacramento analog VHFs (even get a watchable KTVU Ch 2) and fair on Sacramento analog UhFs. KHSL analog 12 was also very good to excellent but Redding (all of them) is/was very poor (hills I suppose).
I was surprised to get a good digital 10,13,31,and 58 from Sacramento, but it does get iffy due to weather/tunneling effects.
What I couldn't understand is why the digital 12 (43) is so poor. Months ago I talked to the KHSL engineer and he told me they were soon installing/upgrading the UHF DTV transmitter. That helped, but it is still very poor, even pointing the antenna directly in the direction of Cohasset. Sure there is a hill or two between me and the xmitter, but remember the analog was fine.
I just stumbled upon this which, I think, explains some (if not all) of my problems:
(Sorry the forum won't let me post the URL. Anyway the the short form of the site is: fcc.gov/dtv/markets/maps_report1/Chico-Redding_CA.pdf
This shocked me. It looks like KHSLs choice of a UHF (43) over VHF 12 coupled with reduced effective radiated power has significantly reduced its coverage and created pockets of no signal WITHIN its former coverage area.
I, for the life of me, don't understand why they would do this, unless they are just cheap (can't think of a better word). If you look at the coverage maps at the same site for the other stations, and for Sacramento, the Bay Area, etc, it shows most stations gain coverage with transition to DTV.
I don't know if anyone from KHSL engineering reads this, but it would interesting to know the rationale about its coverage, as well as any tips to get better reception.
We can watch CBS on 13 DTV but miss KHSL local news, such as it is.
BTW, I have a very long coax run from the antenna, I am going to try a receiver at the antenna to see if I get better results. If so (and I hope so) then I can maybe solve (or work around) the problem.
Thanks for listening,
