Assuming CBC is digital: I would try a complete rescan on your tuner.

CBC in Halifax is CBHT-DT Ch 39 (Virtual 3.1).

I'm doing another re-scan now. Easily picking up 5.1 and 8.1. Thanks for the fast responses!

Now on CBC 3.1 it says failed to receive broadcast E202.

Try turning off the amplifier, if you can (unplug power if necessary). You are so close to the transmitters that maybe that amplifier is adding distortion due to the overly strong signals being received. CBC is the strongest of the three stations.

Agreed with above: Too much signal is just as detrimental as not enough.

That's rather funny because i have done just that and am now receiving all channels again. Amp is now off. Who'd thunk it. Thanks!!

It's now my turn to complain about not receiving CBHT-DT Ch 3.1 in Halifax. I have never had a problem to receive it but today when I turned on the OTA, the TV could not lock the CBC signal. So I re-scanned and surprise CIHF1 (Global) appeared on Ch 8.1. Global must have boosted their signal since I've never been able to receive it before. But still no CBC. CTV is fine on Ch 5.1 as usual. I'm 14 miles from transmitters using amplified rabbit ears. The amplifier is needed to receive Global.

I'm not sure if this helps:
CTV is using the C100 FM tower, whereas Global and CBC are using the CBC tower.
CTV is using more power so its Valley retransmitter has a usable signal.

Yes, I was aware that CBC and Global shared the same tower. Global transmitter power is (was?) significantly lower than CBC so I wasn't surprised before that I never received it with an indoor antenna "way out" east of Cole Harbour. I can receive CTV even without the amplifier turned on but not CBC. The only thing odd is we are receiving an ice hail storm right now.

Added: So the final story here after trying various things is that I can now only receive CTV and Global. No CBC anymore. Perhaps swapping CBC for Global is a good idea anyway! Curious to know if anybody knows any technical changes that may have occurred at the CBC tower or with respect to transmitter power changes.

cyberham, Your post has been moved to the reception results thread for Atlantic Canada.

I haven't seen any applications or approvals with regards to Global stations in Nova Scotia recently.

Likely your results are the effects of changing conditions with the warmer temps. Or possible maintenance at the transmission site.

Umm...the purpose of this forum is for users to discuss reception. I won't report a transmitter problem until, and unless, I know there is one. That's why I'm asking for feedback from other members.

There is no requirement to be snarky, as an ex-resident of Dartmouth, I was only trying to provide assistance.
I used to work at the C100/ Bounce 101.3 Engineering department and transmitter site and I was only trying to offer you a solution. I know for a fact, if you called the switchboard at CTV and asked to be transferred to the Engineering dept, they would be more than willing to help you. I don't have the CBC direct number at the transmitter, but I found that info on their website.

It is quite plausible that the work on the Global transmitter has forced the CBC to lower the power on theirs as a short term measure. a quick phone call could answer these questions.

CBC's issues have been confirmed. Posts regarding outage have been moved to Station status thread for Atlantic Provinces (http://www.digitalhome.ca/forum/showthread.php?p=1396673#post1396673).

All three OTA HD signals (CBC, CTV, Global) from Halifax are now receivable east of Dartmouth for first time ever on my amplified rabbit ears at 14 miles away from transmitter towers. Global must have either increased power or changed antenna pattern: this is not a seasonal temperature change effect. Now is the time to try to receive these. In Halifax city, almost anybody should be able to get all three signals with a simple antenna.

Hi,

I am from Fredericton North and I recently got rid of my cable provider.
Now, I want to find the best option to receive the main broadcasters, like CBC/CTV/Global with a roof antenna.
In terms of hardware, I only have a dish on my roof which was installed by the previous home owner and I wonder if this could be a possible alternative... but you will tell me about this.

So far, I took the following signal analysis test on tvfool.com, but I am not sure they are 100% accurate.
I read someone in this forum from the west part of Fredericton can receive the Maine broadcasts which according to tvfool.com I won't be able to... but reality may be different therefore I am asking if anybody from the north side succeeded to get any Maine broadcasts.

Your TVF reports did not survive the posting process...

As for Mars Hill, they are really only a possibility from Keswick Ridge and a few areas directly east of there. Otherwise, you either need extreme luck or a fair amount of antenna effort to get them.

As you may have read from my posts, I am using a DIY Gray/Hoverman built from CPVC and solid core 10-ga copper wire hand stripped from electrical wire. It cost about $65 to make and I bought a satellite dish j-tube mount to attach it to the peak of the roof. It has been up over the fall and winter and is in fine shape. Nothing has fallen off and the reception has not degraded at all.

So a partial answer is that the most useful bit of your dish is the arm on it. Otherwise, the only other thing you could do is to set a precisely made VHF element tuned to the channel frequencies for the transmitters on Mars hill and and mount it in place of the LNB assembly. That way the dish is now reflecting whatever it can get and concentrating it to the element. This would have to be aimed precisely with a compass as the dish would make the antenna very directional. It would also be totally useless for the local channels as they are east(CBC/Global) and south east(CTV/Global SJ) of Fredericton.

If DIY is not your speed, then a CM-4228 should get the job done quite well. I have no reflectors on my GH antenna and I get CTV quite fine so the 4228 should rock it as it does have reflector rods on it.

If you need to, you can use two antennas and link them using a combiner(Not the same as a splitter in reverse). CTV is VHF so you could get an antenna specifically for it and aim right at it and then another for the UHF CBC and Global. The CM-7777 amp will also do the combining duty if you need or feel the need for some high strength signal boosting but there are overdrive issues that may occur where the local UHF are so close and strong already.

Good luck!

Hi,

thanks for the good advice, I will have to look into this, I am pretty good in DIY but the time could be an issue.
Maine was just a wish and it is not determinant, I am in Canada, therefore CBC/CTV/Global will be fine, but I am a perfectionist and if I do it I must be convinced I am getting the very best in terms of ratio quality/price :rolleyes:

Yesterday I did access and posted the signal results in the TVFools forum and they suggested me a Winegard HD7080P antenna mounted above the roof at about 25 feet above ground to be aimed at 168 degree magnetic compass. They also suggested to join this forum as more updated on the Canadian broadcast side.

I have no experience in the antenna brands, so do you mind explaining what CM stands for?

Here are the results again, it should work now: ;)

Sorry... CM is Channel Master.
