Hi,

I can szap many free channels from Hotbird 13E, but none on some frequencies. For example, if the "test" file just contains the line:

S 11766000 V 27500000 2/3

that I took from http://www.lyngsat.com/hotbird.html as many other which instead work percectly, the command:

scan test > channels.conf

alway gives the following output:

tune to: 11766:v:0:27500 (tuning failed)

WARNING: >>> tuning failed!!!

Done.

On the other hand, if I put manually some lines in channels.conf for such a frequency, I can zap to those channels, but in most cases I watch a different channel, not the one I expected to see.

This doesn't happen on other frequencies.

May be of some help the fact that I'm writing from Italy, and I cannot get channels from the scan for the most important italian channels: in particular, none of RAI network, nor Mediaset network, the biggest network in Italy.

Also, the signal became rather good after I bought an amplifier. Actually, I can see and record perfectly fine many channels. I don't think I have signal strength problems.

Any hint will be very much appreciated.

Best regards.
