HD channels moving off Nimiq-4 82W

New thread to try and gather more info on HD channels being moved off 82W, possibly before the death of Nimiq-4. I first noticed this a few weeks ago (Feb 2025). I gleaned some info from other threads nearby (Death of SD; Lifespan of Nimiq-4 and Nimiq-6) although they haven't been updated for a while as of this post. I had to google search and got some unsubstantiated info from the AI distillation of results.

As stated in those other threads, it seems Nimiq-4 passed its expected end-of-life in 2023; Bell renewed their contract to continue using it for 12 months twice, which brings us to later in 2025. With the discontinuation of transmitting SD channels, freeing up a lot of space on Nimiq-6 91W, it seems many/most? HD channels are now migrating to 91W.

From my own observations, it seems the channels in the 200's and 400's are now indistinguishable from their HD counterparts; and each one I checked is coming on the same transponder as their HD counterpart - which doesn't preclude that they're seperate feeds, but its highly unlikely. Scrolling thru the guide, I noticed ~ 6-8 channels in the 200-600 range were labelled "HD" which never used to be the case, while the others were not labelled as such. The SD picture format on the "SD" channels also only shows "Full Zoom" while it can be toggled between Full Zoom and Normal on the HD counterpart. Can't remember if that was the same behavior previously.

Just tonight, I checked my most commonly used channels - the 5 TSN-HD, 5 Sportsnet-HD, 10 US-networks-HD and CBC and CTV Tornoto-HD. All were coming from 91W except CBS-East HD and Sportsnet-One-HD. So at this point, some HD channels are still coming from 82W. Presumably there's others if someone has time to check!

I checked the signal strength on all transponders on a sunny clear day last weekend. As I live on the shoulder of the satellite footprints, I'm used to signal strengths well below 95-100. What struck me as unusual was that ~ half the transponders on 82W had dropped by ~ 9-12 points from my previous measurement 3 years ago under similar conditions. These were 3, 7, 11, 15, 19, 23, 27, 31; 2, 6, 10, 14, 18, 22, 26, 30. By contrast, others (notably 8, 12, 16, 20) were 3-5 points higher than previously, and higher than I had ever measured in the current location or my previous house a few miles away which had a totally unobstructed view. Is this drop-off in signal strength on certain transponders a sign the satellite is dying, or could it be controllable if those tp's are sending few/if-any channels?

Sadly for me, I have a less optimal view of 91W with a little tree obstruction. But measured under same conditions at same time of year, my signal on all tp's on 91W was ~ 6-8 points lower than 3 years ago. Seeing some of the 82W up's actually stronger was a particularly frustrating finding. Are others also seeing 91W signal strength dropping?

Any thoughts - is this what we have to live with until Nimiq-6 also passes its EOL in another 2-3 years? And if nothing is being sent from 82W in coming months, can I gain anything by repointing my 20" dish with DPP quad LNB slightly to optimize 91W signal? (It was possibly optimized for 82W in its current location as I didn't need SD channels from 91W - but that was 5 years ago and I can't remember everything!)

Thanks - and thoughts/corrections welcomed.

Transponders can lose power output with time. Other issues are reduced power from solar panels due to damage and reduced battery capacity which affects the amount of power available when the satellite is in Earth's shadow. There have been cases where up to half the transponders were deactivated due to component failure or to extend the usable life of a satellite.

In that case, it may be be better to use a 24" dish with a legacy LNB. Depending on the receiver, DPP equipment may not be necessary for just one satellite.

I have the standard 20" dish with DPP quad, and it feeds a single receiver - a 9241. A single line of coax runs from the dish thru the house to the receiver location, then a DPP separator feeds both inputs on the 9241. I'm unlikely to upgrade the receiver, but have a spare 9242 in storage in case the 9241 dies. I thought those units required DPP input, but its been many years since I messed with the equipment, so could be mistaken. I also have some legacy LNB's and SW21 switches that could take the two outputs of a single LNB onto a single coax to the receiver - will the separator still work in that case?

New info for this thread on the April bill from Bell:
Starting June 1, 2025, On Demand content and Pay-per-view movies will no longer be available through your Satellite TV receiver(s). Don't worry, On Demand content is still available through the Fibe TV app and you can still enjoy Pay-per-view live events. Also note that the way recordings can be managed is changing. You'll just need to manage them through your PVR and the Fibe TV app separately. For more info on the Fibe TV app, please visit bell.ca/apptv
I guess this further reduces the required number of transponders to send the current service, and eliminates many HD-PPV-movie channels that now don't need to be moved to Nimiq-6.

Bumping this one up...

I posted a longer message on the Installation Forum - but relevant to here: I'm now seeing no signal on all transponders from 82W except for tp21, which still gives a signal strength of ~ 65. Are others seeing similar? (Can someone with good line-of-sight check? :) ) Partly curious as to whether all the other transponders have died or shut down in the last couple of months - but also as I used signal strengths on 82W for pointing the dish!

Thanks!

Nimiq-4 at 82W shutdown by October, 2025

I posted about Nimiq-4 at 82W a couple of years ago. In summary, Bell's initial 15-year contract with Telesat expired in October 2023. Bell renewed for 2 years with an option for a third.

I checked Telesat's Second Quarter 2025 Financial Results Call and they confirmed "that satellite has about another year plus of life on it, but it's not our expectation that Bell will renew when that contract comes up in October. They'll consolidate their activities on Nimiq 6."

What signal do you get on those 4 tps? This weekend I could see 15 and 21 (signal level 48 and 68 respectively), but nothing on 16,20. Mind you, I'm the shoulder of the satellite footprint as well as having minor tree issues in summer for my line of sight with 82W. (As opposed to major tree issues with 91W - seems we have that in common! :confused: )

I'd be surprised if there's any channels left on those tps. I thought everything had migrated to 91W earlier this year. Certainly from my limited selection of channels (digital starter, US networks, TSNs and Sportsnet's) everything I've checked has been coming from 91W for some months.

This what I noticed since the loss of 82 and everything moved over to 91, so maybe hang onto those SD channels

  • Pixelation and Jitter on HD Channels: particularly during live sports or action-heavy scenes, stuttering, and a "jittery" or choppy picture. possible sign of aggressive video compression.
  • Worse Picture Quality on HD than SD: despite their lower resolution,SD appear "cleaner" and more stable than their HD counterparts.

Thanks, for now we are just watching the SD channels and see how that goes, they appear to be OK and a bit better than the HD for now. I have 100% signal strength on some of the CTV channels in HD so strength is good. Thanks for the link. I have a 9400 receiver which is 9 years old, so maybe it is showing signs of issues as well.

Yes, it was the original station resolution which was typically 1080i and it was the MPEG2 signal without much, if any, compression. The picture was much better. The irony was that the 6000 receivers used at the time had a poor quality graphics overlay chip that caused a lot of picture degradation. I had an adapter called a 169time that bypassed the graphics chip to delivered the original picture and it was very good. Then the picture quality started to deteriorate as compression was used to add extra HD channels. Just before Bell switched to MPEG4 they lost half a satellite and adopted a new scheme called adaptive compression which resulted in a lot of issues similar to those in post #25. 720p was adopted a bit later.

It's starting to look like Bell Satellite is slowly being switched to a combined IPTV and satellite service. I've even considered subscribing again and using the Bell Fibe app to watch TV. It wouldn't be much different than what I have now, probably more reliable on the IPTV side but it would cost more.

Outside of OD, Bell has been 720P since I created the following FAQ 17+ years ago.

It's hard to get TV Listings with Zap2it being gone.
You can still get the same TV Listings using a direct Gracenote link instead of Zap2it. You can even use the same user id and password.

Gracenote/Zap2it didn't always delete old channels. Plus I think I read that some SD channels were upgraded to HD in place, without assigning a new channel number. Other SD channels may be remapped to the HD channel.

As I posted about 3 weeks ago, Nimiq-4 at 82W has at least a year of useful life left. Telesat said that Bell decided not to renew their contract for another year and to consolidate their activities on Nimiq-6.

Nimiq-6 was launched in 2012 and could provide service until 2030 if it also lasts 18 years.

I don't see Bell (or Rogers) paying to launch another geosynchronous satellite in 2030 to provide satellite TV until 2045. Linear TV will be long dead by 2045.

Bell has already introduced their satellite TV customers to cloud PVR recording (similar to the new Fibe TV) and will probably transition them completely once Nimiq-6 reaches end-of-life.

From other posts, it sounds like HD channel quality has gone down a lot and the SD channels that were supposed to be shut down to make enough space are still there. I went through the same thing about 15 years ago when Bell had satellite issues. It's not pretty. At that time, Bell leased an unused, retired satellite parked in orbit to compensate for the partially failed satellite.

@MCIBUS, there is a good chance that Bell Satellite will be shut down in 4 years. The same goes for Shaw Direct. The answer is to use fibre or cable. For those that cannot do that, LOS satellites will likely be usable for TV and streaming by then.
