BVN TV signal in canada

<< < (2/3) > >>

sparkycivic:
I've been getting reports from my users around Manitoba here, that the periods of bad reception seem to come and go on half-hour slots. one show will be 100% good, then next show unwatchable, or maybe a few shows in a row good or bad, but usually changes between shows.  Perhaps the satellite is firing thrusters on a schedule for orbit maintenance, that ever so slightly disturbs it's orientation and causes those of us at the edge of the beam to gain or lose strengh?
I have recently aquired some even larger dishes.  I'll experiment with them once I fabricate mounting hardware which is missing, and when the weather isn't deadly cold...

DrSat:
After further examination, the issue could be with the Eutelsat 113 W A satellite itself on horizontal transponders rather than the uplinker.  As i'm sure you have all noticed already, the signal on the 11989 (MTA) and 11994 (Hope Channel) vertical transponders is much stronger than the 12089 (BVN) Horizontal transponder.  For those of you with a DVB-S2 receiver, you should have noticed that the Reuters Live transponder on 12046 H 14300 DVB-S2 transponder has also been impacted.

As I keep getting complaints from our Dutch customers and considering the fact that this is an official FTA service for home users published on their website, I have contacted ADTH, the uplinker for this transponder located in Atlanta, GA.  They told me that they recently received reports from BVN directly that some viewers are having issues.  In response, they have setup a 90cm dish at their uplink station connected to a spectrum analyzer in order to monitor their transponder and advised me that it appears that their signal levels are normal with this system.

I have advised them that since late October / early November, many people here in Canada have experienced their signal level drop.  Before they switched from their full power 12080 transponder at the begining of 2015, a 33 inch dish and low noise LNBF were sufficient for reliable service here in the Toronto area.  After they switched to a half power transponder on 12089, quality went down about 10% which raised the minimum dish size requirement for reliable service to 36 inch but with this most recent issue, a dish of this size now has occasional issues during inclement weather.

As they are not seeing any issues with their signal down in Atlanta, a possible cause to the issue would be if the antenna probe on the satellite for horizontal channels has somehow shifted or has been damaged a bit which would impact fringe coverage here in Canada.  At the end of the conversation, the uplinker advised me that they will contact Eutelsat in order to report the issue to see if anything can be done in order to improve the output level of their transponder.

DrSat:
Attached some specrtum analyzer plots.  It does appear that there also might be a cross-pol issue at hand as we can clearly see a peak on 12089 even on vertical, although much narrower.

Plot of vertical polarity with some sort of signal being shown at 12089 MHz on the last peak at the right hand side of the graph.  We can also see the Hope channel transponder at 11995 on the graph.

DrSat:
Good news! Just got a call again from the uplinker who confirmed that Eutelsat just increased the output level for their transponder by 1.5 dB!
Over here, this resulted in an increase of about 7 to 9% signal quality so now the BVN transponder is about the same level as the Hope Channel transponder on 11995.

And after....


Please check at your location how much you are getting now and post in this thread.


Thanks,

I'm so happy to hear that I'm not alone with the frustrating experience of trying to keep BVN online for myself and my friends who rely on me! I had reached out to Atlanta DTH several times, and got no response.  BVN themselves also stopped responding to me, without giving any hopeful information.

It's the impossibility of rural unlimited internet service in this area that prevents most of us here from just using the online streaming and forgetting about the satellite reception altogether.

I'll keep hoping for a better solution...

Thanks for what you have done!
