Re: changes on SR1 to receive HVS1 and BASIC at the same time ... if possible, of course!

Ciao David....hard day...today!!!! 1st floor done.... tomorrow the second one!!
For today I've stopped the "concrete" job and now,start the "electronic" job... :))
I've read the signal from consol ,with more attention:
My es/no , with cloud, is 7.2 db
Demodulation link margin is -2.4 db
In my option, like from your suspect, I think that HVS1, with these low signal, is very very hard to decode.
Later, finances permitting, I will think of an upgrade of the satellite dish.
Unfortunately, finances are now spent on household expenses
Thanks anyway for the support!
Ps ...I've installed the "BS & HVS-1, connected" script...
Have a nice day!!
I bet the house will look very good when you are finished, but the work must be tiring!
Thanks for that - you've explained the reason for HVS-1 failing. Approximately, the link margin is about 6 dB less than the Es/No for the basic service, so in the cloudy conditions you have a margin of just 1.2 dB. So the signal only needs to be 1.2 dB lower, and you will lose the basic service. For the high-volume service the difference is about 9.3 dB, so the signal is already 2.1 dB below the threshold - as you have indicated.
Until you get a better signal, just install the BS-alone script, as you will lose BS data by trying to receive the HVS-1.
But what size if dish do you have? Perhaps it just needs aligning perfectly to give you a little more signal.
