I patched stb988*.c to see if it immproved my reception, but so far it 
looks pretty much the same: transponder on 11093 is always perfect and 
all others are unreliable (meaning: going from no lock to perfect image 
between times, and if I get no lock tuning to the good transponder on 
11093 MHz and tuning back to where it did not work will give me a lock 
in general), so... I was lost.
I also tried to substract 4 Mhz to the tuning frequency even up to 10 
MHz but with the same symptoms.
BUT the good news is : ADDING 4MHz gives good results: perfect picture 
on every transponders!
