Rockin' Rick, the correct way to CHANGE C-Band frequency value so as to let these work with Ku-band settings is as under: 5150- MINUS- C-Band frequency - PLUS- 9750 EXAMPLE: 5150 - 3700 = 1450 + 9750 = 11200 Now if you use this 11200 with your Ku-band settings...you will receive the channels of C-ba...
