If the 922 hasn't lost it's memory, (more on that later) it is definately something you will want to keep. Even is if has lost the sub memory it can still be used to operate the big dish for the Fortec. Don't lets someone talk you into getting rid of it because it is "old" or usless. IT IS VERY USEFUL! If you already have the 922 + C band dish/lnb/actuator system set up you have exactly what you need to use the Fortec on C band FTA. An inexpensive splitter (special for satellite systems,
NOT the ones used for in home cable tv splitting.) will let you use the C band antenna for both receivers, but you will still need to control the position and lnb polarity via the 922.
If you friend has "everything" it is possible that he is doing something illegal. Currently the totally free hack has been stopped but has been replaced with a system that shares an "everything" subscription decryption data with others over the internet. If he has to have an internet conection and a satellite receiver to get his everything then that is likely what he is doing. You dont want to go there, I would advise declining any offer of such.
You mentioned -
I also have a fortec receiver. I almost have it ready but lack the courage to move it and mess up what I presently have.
With a better description and more details it will be easier to assist you in getting everything situated.
Overall, you seem to have viutually all the equipment you need to get a good start into DVB FTA and even some FTA (DCII) channels on the 922 that the Fortec cant get. Look in the 4DTV section for help and pointers on using a 922.
For a complete system, I can see you adding a
satellite signal splitter to share the C band from the big dish between the two receivers, a DiSEqC or similar switch to let the Fortec select between the two feeds and possibly a motor (positioner) for your Ku band dish.
