Test report: it looks like good transponders (FEC 3/4, vertical 
polarisation, SR 30M) that used to lock will lock a bit faster, so I'd 
say that good things are now even more reliable and fast.
BUT the bad transponder (same charact but different FEC, 5/6) still 
does not lock, at least not in 30s. So there still is something fishy. 
And the problem is in data search as I can see several CARRIEROK during 
the search but each time the data search (I'd guess FEC lock) fails and 
after some time the freq is too far away and status becomes NOCARRIER.
I'd be glad to test further.
