setup with C-band and Ku-band

[jowski]

I have a system where C-band has an LOF of 5150000kHz, Ku-band has an LOF of 10750000kHz and a 22kHz switch controls which band is selected. Which LNB type do I select? Where in the file system in the file that has the LNB's so that if I need to change something, I can?

Thanks,
Jim

I have a patch that will add a C-band 5150mHz LOF, ku-band 10750mHz LOF, with a switching frequency of 8000mHz to dvb_satconf.c so those of us in North America with our "almost standard" setup can use an MOI. What I'd like is for TBS to incorporate the patch and release a tvheadend tarball so that we can apply it and not have to set up a cross compiling enviornment. It would be really great if it could be part of future MOI versions of tvheadend too.

Thanks,
Jim

The patch in the previous post was for the older (3.4?) version of tvheadend. For 3.5, here is the patch which I call linuxdvb_lnb.c.patch:
