I am in 01867 (Reading - junction of 93 and 128 10mi north of Boston) and I can get everything except PBS.
I have a DTC 100 and a big huge antenna from the Shack mounted in the attic. Probably overkill. I do not have a rotor.
What channels does PBS broadcast on? My DTC 100 seems to remap the channels to the same # as their analog counterparts. For example, I used to be able to receive PBS on 2-1, 19-1 and 80-3. Are these all GBH ?
I've never seen 80-3 mentioned around here, and I was wondering if anyone knows what my DTC 100 is doing!
If I peak WBZ-DT, shouldn't that get me the best GBH-DT signal? I thought I read that they are on the same tower.
Please help me get some good HDTV demos for this weekend for visiting relatives.
I used to have a DTC 100 in Lexington. I kept the remapping turned off. It is a set up option, but you must rescan after setting it. I find the real transmitter channels much less confusing. You should get WGBH-DT in Reading, but you could get interference from analog 19. If the DTC-100 sees the analog 19 the digital 19 usually goes away and you have to do a rescan to get it back sometimes.
Regarding your antenna, it is not overkill if it is in your attic. A big antenna is generally good and better than using a preamp for most people. You may need something better though, depending on your multipath. I would suggest you use your antenna for VHF only and then add a good UHF antenna on a rotor like a Channel Master 4248, if you have room. You could set it up so only the UHF one rotates if you want.
Depending on where you are in relation to hills, in Reading you should have a choice of 2 pbs stations: WGBH-DT or WENH-DT.
WGBH-DT is channel 19 and maps to 2-x and is in Needham on the tower with channel 4 etc.
WENH-DT is channel 57 and can map to it's analog number channel 11 from Saddleback Mtn in NH.
Channel 80 is the number used by the PBS HDTV satellite feed and can show up on your tv if the signal is just being passed through without local station relabeling. With this number you really can't tell which pbs station you are watching which is another reason to turn off remapping if you can! I have seen it on both but I think WENH-DT lets this channel number through more.
WBZ-DT is indeed on the tower with 19, but you need to peak the channel you are watching especially for 19. Most people need to re-aim due to multipath, but even if you have little of that, 19 analog will interfere so to get 19 digital you still likely need to turn your antenna to try to null 19 analog as much as possible.
19 20 30 are all on the same tower in Needham, but I have to aim my antenna individually for each. I can usually find a compromise setting that gets any 2 of them, but not all 3 reliably. And the aim shifts I am talking about are like 20-30 degrees with my rotor!
