Once upon a time Guido Fiala shaped the electrons to say...

Are those all "v"-Polarization only (like Pro7 and Sat1 both(!) are ?

>i do now get the decoder frozen after 30 seconds, 

If the effect is only on the "v"-polarized:

If you have at least 2 cards and no Multiswitch than you have
to set (currently) "EPGscan=0", because the EPG scan function switches
the other card to "h" which has priority over the "v" voltage.

Turn Diseq off too.

Those are the easiest tests.

"plus" would be really surprising for the north hemispere now :-)


>my LNB is currently exposed to ... or icicles at the satellite *g*

Hm, i don't think that those will break anyway just by channel switching ;-)
(Or do you have a motor dish?)



Often receivers (like VDR) are able to add an extra frequency offset
to all channels.
Maybe your LNB is a little bit "out of tune" now because
of the temperature and this offset ma help?

Try to estimate the frequency whre you lose receiption of
a channel and see if the middle frequency between is that
what is expected.
Else go into setup and add the offset.


Remember: The receiption is "digital":
There is only "good image" or "no image".
The range with "bad image" is very small.


Pls. tell how you solved the problem.
