Something strange happened here tonight - I was watching the Lloyd Robertson thing on CTV Halifax when it crapped out completely at 10:40pm. CBC HD also started acting up - both had single digit signal quality bars and abnormally low SNR dBs, with the TV unable to get signal lock. Global was weak, but consistently so over the last few days. I thought something affecting that many stations would be an antenna problem, seeing as there was no traffic outside that would add reflections or distortion. So I tuned into CBC French and it came in at its usual power. Thus the worst affected stations are CTV & CBC HD, both on different transmission towers, and my setup seems about normal. Any ideas what's going on?
Could be atmospheric conditions bringing in distant (and interfering) signals. On a mailing list I am on, someone in Cape Cod, Massachusetts reported receiving CJCH about 25 minutes ago.

I should note that if anyone has not noticed, that CBC in Freddy jumped to ch 31.1 the same day that I temporarily caught them on 19.1.

With CBC, is your sound alright or does it sound weird? Since yesterday, we are having the Atlantic CBC on ROGERS and their sound is all goofed up. It mainly comes from the rear speakers. I haven't scanned with my TV to confirm if it's just on the cable or the OTA version is the culprit.

So far, I have only watched on the stereo setup in the bedroom.
I will check it tonight on the 5.1 downstairs.
The picture quality last night was AWESOME though!!!

I heard the same audio problems last night on 13.1 from Charlottetown.
Does the ATSC scheme provide metadata for program information? So far all I see on my Sony TV is "DTV Program". The same is noted for my Magnavox STB.

I'm in Moncton too. I'm going to try to get CBC tonight and I'll let you know how it goes. I have a winegard MS2002 and have had global running on my htpc since it came on line but haven't tried a rescan as of yet. I've been waiting for CTV to come online but where it's the weekend I think I'll try it out.

Here in St. John's, the 5.1 stream is the main audio and even though the feed is mono (I assume, as it was mono before the switch), the centre is silent for at least local programming and all the sound comes from the L/R speakers. I have not noticed if any programming is actually 5.1. If I pick audio 2, it is the same programming in supposedly DD2.0, which my Yamaha automatically decodes as mono in the centre channel! Growing pains I guess, but at any rate it works and sound better than pre transition.
I have noticed some crackling on the sound at times....again, growing pains?

For the first time in a while, I find myself a complete noob and overwhelmed with some aspect of technology. I've done my reading and I think I have a handle on what I need but I want to make sure.
First, here is the tvfool report.
I'm looking into an RCA ANT-751 antenna and a Winegard AP-8700 Preamplifier. The antenna will be mounted on my roof, however I'm in a small valley and there is about 50' worth of coax between the antenna and the splitter, plus an additional 50' from the splitter to 3 tvs. So even though I'm fairly close to the transmitters I've always suffered low signal due to trees and topography.
Does that sound reasonable? Any advice or tips? Thanks

Wow, thats an unusual post transition TVFool. All of your practical channels are vhf. :eek:
Your channel 9 is in a significantly different direction than the rest of the available channels. I think the RCA ant-751 may be too directional to pick it up without a rotor.
I would build a simple vhf 23 inch diameter QIC loop with no reflector and use it with the preamp you state.
Or for more gain, the double 24 inch QIC hoops.
Holl_ands has specs here : http://imageevent.com/holl_ands/loops/vhfloop
This antenna is bi directional unlike the RCA ant-751. (and the double hoop would be as much gain as the ant-751) And since soft copper is sold coiled, this antenna is practically built for you if you carefully unwrap the coil, heh.
If using a 4-way splitter for 3 TV sets, remember to terminate the unused outlet.
I've always suffered low signal due to trees and topography.
Try experimenting with different heights and tilting towards the top of the hill.

Somehow I think that TVFool hasn't quite caught up with the transition to DTV in Halifax. CBHC (3) is now on channel 39 (virtual 39-3) and CJCH (5) is now on channel 48 (virtual 5.1). CIHF remained on channel 8 after the switch. If you click the "Pending applications included" radio button you'll see them.
Channel 9 is a the same station as CHIF. SO I'm really only hoping to get the 3 main channels and they all come from the exact same direction.
I was originally looking into a GH antenna, but to be honest that's a bit over my head at this point. I'm still at the point where I'd need step by step instructions and a parts list (instead of a nec file). Now I'm exploring a M4 antenna. The real problem is my 3 month old has stripped any spare time for projects I have! So I thought I'd just buy one.

If youre just after those 3 stations, then a very simple and cheap to build GH0n would do great.
amoniave is in the process of building one now here:
If you dont already have 3/4" mast material, 3/4" X 10ft EMT is only about $3.
GH0n specs here:
More gain than the ant-751. :)

Thanks for that info, FishDisease. Our main CRT in the living room is down, but I've been trying to get channels on our little LCD in the bedroom for the past few weeks! I admit I didn't go looking for the information that aggressively, but the information given by the stations has been horrible! Unfortunately, there's noone to really complain to on this. The CRTC has met it's mandate, and the stations themselves probably don't care if they didn't take the time to properly advertise the switch in the first place...
All the ads for the changeover were good. Of course, they were almost all included with a little 'push' to try to get you onto their satellite or cable affiliates. They also advertised Aug.31... and Global went dark MUCH earlier than that without notification. They also had a total lack of information on which channels they were going to! Global was easy enough, but without FishDisease's info on the other channel numbers, it would have taken a lot longer to set them up. My TV actually 'found' digital channels 3 and 5, so I thought my little rabbit ears just weren't catching enough signal...

I am at my parents in West Branch River John. 30KM Driving Distance from New Glasgow and i am get CBC and CTV in HD from PEI in my dad bedroom but not in the other bedroom. i am using a homemade indoor antenna that i build and i used to get Global Analog from PEI to my parents house but not anymore. what going on.
2011-09-04, 06:42 AM
UHF 27 Global from the South works great. 11 SRC from the north is a bit more touchy, probably because it is VHF and has to cross the city to get to my downtown basement home.
Outdoor smokers, cats and garbage trucks have all interfered briefly with the signal. Fog, oddly, hasn't.
The advantage of not being on the border is that there really isn't any incentive to get a good antenna. My $5 rabbit ears work fine in the window, and catch all two digital stations while CTV gets it's act together.
2011-09-04, 09:25 AM
At my house in Charlottetown I used to get snowy 8 and 13 from rabbit ears right next to my TV. Since the DTV transition I had to drill a hole in my floor and run a wire up to an upstairs bedroom closet where I tacked a pair of rabbit ears to the wall in at 90 degrees to the CTV transmitter. This arrangement pulls in both stations well. I only have one TV so no splits. If I use a UHF LPDA (Silver Sensor clone) I get Global on some days but not others.
I think in your case you may have to stick your homemade antenna outside or higher up to keep getting Global, or maybe get a preamplifier. How did Global look before? I find if you could get a decently clear picture before it comes in now in digital.
I set a friend up with a CM4228HD and CM 0068 pre-amp in a second-floor crawl space. He has it split 3-ways and has 1edge reception. It's working well for him - no drop outs so far that he has noticed.

I have heard from a couple other OTA viewers. My next door neighbor is about 100 m from me and is a little higher with fewer trees, but more leafy types and he gets good signals for both NTV and CBC using rabbit ears (2nd story) with a Zinwell box showing high signal levels.
The parents of a friend live across Conception bay (Upper Island Cove) and also seem to have no problem with reception using rabbit ears and I believe an AccessHD box.
The viewers are astounded at the picture quality on their CRT displays compared to the old analogue signals. My neighbor says the picture is vastly superior to the cable channels he is also subscribed to. Imagine if they saw the results on a new 1080p set! It seems as if those with the newer sets all have cable and do not understand the OTA concept....though we do only get two channels

Finally got to checking CBC Freddy for audio and yes indeed, it is all messed up.
On the 5.1 setup is sounds almost like when you reverse the polarity on one speaker and you are out of phase. On the 2 ch in the bedroom it just sounds odd compared to CTV or Global.
It is interesting, though, that CBC is broadcasting in 720p and the others are in 1080i. Can't see it being related but considering the outcome so far... Just an odd coincidence regardless.
