Many receivers wont lock onto very low symbol rates. Try this trick - it used to sometimes work for me on low sr channels.
Detune the receiver 2 khz at a time either side of the nominal frequency +/- 10 khz.
So if the frequency is 12000 khz you try 11998 11996 11994 11992
11990 then up 12002 12004 12006 12008 12010.
If the lnb oscillator has drifted off frequency it can help lock it.
