SFC is freeware and should be distributed as such.  It was written in June, 2000 by Bill Collignon, a satellite television earth station operator, to assist in converting frequencies in the L, C and Ku-Band spectrums.

This software is simple.  It contains only one command button, which is used to exit the program.  It is designed as a simple, easy-to-use tool which can convert L-Band up to C and Ku-Bands simultaneously.  It also converts C and Ku-Bands down to L-Band, as well as converting C and Ku-Band uplink to downlink frequencies, and vice versa.  

Any questions/comments regarding this software should be directed to the author at eroica@crosswinds.net.  

Happy converting!
