Thank you for your comments. As I am 87 I am not allowed on
the roof any more (!), so my dish was installed by a professional
who used a receiver for the alignment. There was some doubt in my
mind about the satellite alignment and the technician spent over
an hour adjusting and checking that we had the right bird and
alignment. The only thing that was not done right was the skew
setting as the interfering transponder was not active at that
time. With the interferer on, I get a basic SNR of 11.5-11.7 dB,
with it off, it is 13.6 dB. If I get the installer back for the
skew, I might pick up a dB or so, but even then, its pretty poor
for the HVS services and I don't like spending on it.

there must be something wrong with the alignment of your dish. My
125 cm dish gives me a SNR of about 15 dB. And a link margin of
about 5 dB for HVS-1. Maybe adjusting your dish helps to improve
you link margin dramtically?
Basic Service was the starting point of Eumetcast. Technical
progress requires much higher data rates for today's satellites.
So Basic Service becomes more and more outdated.
Data rates required for the new GOES E and W satellites will not
fit into Basic Service at all.

We don't seem to have the same idea of what a 'Basic
Service' is for. I would have thought that it would carry all
the data of principal interest to UK and European persons for
general weather prediction and meteorological interest, and
usable for education services. GOES E and W are definitely in
that category. New satellites with high performance
radiometers and many channels, or those serving distant parts
of the world, would more appropriately be carried on the HVS
channels, as they would not be of the same interest to the
first category of possible users. HVS users might be expected
to carry the higher costs of reception as many will want the
HVS services for professional use or revenue generation. I am
definitely in the first category of user and having a usable
margin of only 1.5 dB for the HVS channels are unwilling to
put the extra cost and effort into getting them. My pitiful
1.5 dB comes from as 125cm dish, which cost me over 400€ a few
years ago to buy and have put in place.
