There is a link that include transponder lists.

This script will convert fastsatfinder's transponder lists to kaffeine format.

I used 0130.ini file for Hotbird.

cat 0130.ini | awk -F "=" '{print $2}' > out

for aa in `cat out`
do
echo $aa |sed 's/,34/,3\/4/; s/,56/,5\/6/; s/,23/,2\/3/' | awk -F "," '{print "S"" "$1"000 "$2" "$3"000 "$4""}' >> Hotbird-13.0E
done
