That would explain why 32-1 is acting like it is.

I'm hoping they fix the problem soon.

Signal strength for 19.1 hit a few bumps in the road, 100% to 40%, for a few minutes at 11:17AM, on the main TV.

EPG is just a joke in Canada, so I,m not optimistic in seeing that fixed anytime soon.

The lack of EPG data is a royal PIA.

I find it is as good as it was a day ago, in analog lol

also guide HD and time may all have to do with that lightning

Excellent audio and video reception for 19-1 in northwest Caledon (Charleston Sideroad and Mississauga Road). Also picked up 51-1, 51-2 and 51-3 while reprogramming. Haven't been getting 2-1, 2-2 or 2-3 since the spring but suspect they will be back when the weather cools off and trees shed their leaves.

Reception in Etobicoke is a bit spotty for me. Signal hovers around 80-90% but then dives to 0-40 at times. CBC is stable though at 90-100

I recorded a few things overnight and the audio is out of sync by at least 100ms on all programs.

JmanGTA,

Sounds like a bit of overload on your tuner. Wait until September 1 for the analogs to shut off and then see where things stand. You'll probably be fine.

They assured me this was in their plan when I asked earlier in the summer. Call or email them about it. I already did. The more the better.

But I bet they are working on a few other things like the HD outage to the southwest.

I'm glad to hear that, thank you. I'll wait a few days, as they have bigger fish to fry today.

getting channel 19.1 tvo here, thought it might come in better as it's the strongest channel in the toronoto market now but doesn't come in any stronger than the cbc which is funny because it has at least twice as much power?

Not sure what the maximum SNR your tv can indicate? or if it's even truly indicating SNR, assuming it is, you won't lose a lock until it degraded to ~ 15 dB anyhow. That would take a huge fade, and/or a huge amount of interference. So practically speaking I don't think there is much point indicating higher SNRs than the 27 to 30 dB range for 8VSB / ATSC modulation. Also keep in mind SNR is a measure of signal "Quality", not signal "Strength".

well i'm receiving 19.1 toronto very well, but i found it kind of funny that it's not coming in stronger. It's coming in at 26-27 db on my tv. But CBC from toronto is coming in at the exact same 26-27 db, i thought TVO having an erp of 106.5kw with an average of 79kw would be better than the CBC which has only an erp of 38kw. Or is TVO not at full power yet since i've read on here that channel 19-20 share the same antenna on the CN tower? Just thought that the "100kw transmitters" would come in a little stronger, any thoughts
I'm no expert in this department but is it possible they are waiting for CBC to go full power?

They are planning on the flutuation of the signals and you think the more the better??:confused::confused::confused:

I noticed that TVO signal wasn't as strong as I assumed it be considering the powerhouse the analog was (comparable to CBC) so perhaps it isn't full power yet.

My understanding is that tuners that report an SNR rating as an indicator of signal strenghth generally only report SNRs in the range of 15 to 30 dB.

I suspect that this is because the value is not a measure of absolute power received, but rather linked to the amount of gain the Automatic Gain Control Circuit is calling for. The tuner probably doesn't need more than 10-15 dB of headroom above the minimum required for ATSC decoding (about 15 to 16 dB above the noise floor), and so perhaps you will see most high power stations max out around 27 to 30 dB.

Let us know if the SNR value for CBC changes when it ups its ERP to 106kW from 38 kW. If it doesn't change, then you'll know that 27 dB is the maximum that your particular tuner will report.

I don't see why. I don't think there is anything in the rules that would preclude adjacent co-located ATSC channels operating at 38kW and 100 kW.

Went to another location to rescan and had an issue that a 32" Panasonic refuses to scan in the 32-1 .This is weird as its the better TV in the house for locking on the digital signal's to date. .

Had a 40" Samsung in the same location and it picked up the new channel no problem. :rolleyes:

TVO Ottawa now includes PSIP with station name (TVO) and time (set 4:55 ahead of actual time), but no program being broadcast. Signal strength is 5-6 "bars" on a Samsung.

Channel 28.1 Paris/Kitchener is now 1080i with full EPG data and working on my CM7000Pal tuner (it was only coming in as audio previously).

Channel 19.1 Toronto is coming in 1080i with full EPG data and working on all tuners. Signal strength is about 29dB--just the same as CBLT Toronto for me.

Good job, TVO!
