When I first lost the transponders, as many as 14(always the same transponders) I thought it was because Bell was doing something on their system. I gradually lose transponders up to 14 of them then gradually get them back. This happens sometimes during the year. It happened now and last Autumn.
Then I thought it was the RG8 cable but that was changed recently. So I began thinking it could be the SW-21 or the receiver had a faulty tuner.
A couple of days ago I noticed all my transponder were back except for 3 of them. 9-11-17.
Then I read the following post by Pinza.
They are compressing more and more and using a method of compression on the fly.
They just switched off 3 Transponders on 91 (SD Channels) and it did not affect customers so that tells me that they could add whack of SD or HD Channels right now if they chose to.
This got me thinking that my receiver may have been affected by what Bell is doing.
And the following post where you answered me
@ rogue17, "We are performing maintenance and as a result, transponders 9, 11, and 17 at 91 will not carry signal until April 12".
Pinza are their receiver models that are more prone to be affected by maintenance or is it just that odd receiver regardless of model type that can be affected.
I think my receiver is sensitive to what Bell does wheter it is adding/removing/moving channels or maintenance. At some point at I thought it could be a Sw-21 problem but like I said a few posts up it says OK on both birds on sys info.
