The figures you quote are just measurements of speed, so check what you are trying to achieve?
Any universal lnb can tune to symbol rate of 3,200 as they arent limited to 27.500 or other number.
It may be the receiver that cant 'tune' to that rate (meaning it cant work at that speed), but changing the lnb wont cure ~if the receiver cant do it then it wont. Many modern receivers can cope with symbol rates of between 1,000 to 45,000 fine, and so can universal lnb's too.
