It's all about the Software

Does anyone know of a plugin that works for automatic freq control. on a dish setup with c band LNB ADSC data. I get alot of drift with the sun peaking in and out of the clouds. it would be nice to have a AFC to follow the drift of the freq..

how about a freq drift tracking software for inmarsat c band and L band data. i have looked at the geostationary beacon software. seems if it was modified for all freqs it could work?..possible a automatic frequency correction.
