For the last 3 days I have been trying unsuccessfully to find my inability to scan in C band feeds on both AZ boxes. I have changed out splitters also. Currently I have two of the switches with an OUT and a SAT1 and SAT2. Can I replace them with a 4*1 providing I connect them to SAT1 and SAT2 and the other SAT remain Vacant? Skip

I have 2 splitters conected between the C and KU feeds on my 922. The pass through side feeds the power from the 922 to the lnb's , the other side goes to the disq sw {port 1 C amd port 2 KU]. Hope that helps.

Skip DSR922s don't send diseqc signals. The 922 should be on the DC pass side of the splitter thence to the LNB(s). The switch on the other side of the splitters then can select which LNB the AZbox wants. If you have an orthomode feed horn for C-band or a Corotor II with the 922 selecting polarity you have all you need. For 4 LNBs like a Bullseye II you need two power inserters.

I have a 920. Thanks but I don't speak your lingo. I'm Challenged.

Strange Happens. I scanned G14 on my AZ box with a Ku setting and I receive all these scrambled channels like HBO, ESPN and Disney channels. These are listed as C band on LyngSat but are displayed on my AZ with KU frequencies 11979 H 29997. I was very careful not to mess up the cables. Skip

There shouldn't be any problem replacing a 2x1 switch with a 4x1. The specs on those switches seem to suggest more signal loss using a 4x1, but I haven't seen much difference. If the switch is outside though, I'd cover the unused ports.
However I'm a bit confused re what you're trying to do. The confusion is that you only mention C band, but say you have 2 Azbox receivers. Almost sounds like you're trying to use the switch to feed 2 receivers instead of the switch to feed 2 LNBs to one receiver. It might help to describe your setup more.

Wejones, 12 days ago I lost all C band including analog. I replaced the LNB and now have analog but not on both AZ boxes. I have never had any problems pulling in any Ku feeds. Rick suggested replacing the switches and DiSEqC which I have but I still can't scan in any C band. I tried using about 6 different sats but they all come up zero on c band. I have an AZ Elite an Ultra. This is driving me nuts.

The receiver is actually looking for IF (intermediate frequency) signals which are either 5150 - transponder frequence or transponder frequency - 10750 (C and Ku respectively.) When you get C-band while searching Ku it means your receiver is connected to the other LNB. I never owned a 920 but I don't think they had any capability the 922 lacks save the EPG worked better so I am told. I noticed you scanned the odd transponders. If ESPN is still using TP 9 then the IF would be 5150-3880=1270 which added to 10750 yields 12020 which I expect was your result. If your switch is 22 KHz which is likely for a 2 input the tone should be on typically for AMC-21 and off for Galaxy-14. The usual test is go to C4 and switch between TP 9 and 10. If you still have no C-band connect the C-band LNB to the 920 without splitters or switches. Please post the results.
Edit: Your last post was unseen, skip.

Johbru, I have a picture on C4 9 and 10. I took the cable entering the house and connected it to tha AZ box. It scanned in the espn hbo etc. Same as before. I then took the cable off the splitter and to the AZ box and there was no blue line signal on the AZ. What does that mean? I do get analog channels. Skip

If you have a regular LNB the AZ must be set to Horizontal in order to have enough voltage. If by "Same as before" you mean the C-band is showing as Ku then I would say your splitter or the cable to it has failed. If your 920 is controlling the polarity set it to an even TP say 12. My 922 sees it at a signal of 100. You should get Turner's mux on C 3820 30000 and PBS 12180 30000 on Ku.

{see note 2] If you took the cable off the splitter and conected it directly to the Az box, then you would have no power to the lnb [lnb power comes from the 920] and the blue light would not come on. Sounds like you have cables conected wrong! If you have the splitters , conected between the C and KU feeds to the 920 the other pair go to the Disq sw. {1 for C and 1 for KU. the "receiver" conects to the AZ box. Make sure they are set correctly in the ant set up in the AZbox. Remember the AZ box is not going to change polarity; that is done with the920.

Virginiap20007. I had this problem before I changed hardware so I don't believe I have the cables crossed. If they were crossed would I not be able to receive Ku? Also, I'm aware of changing the AZ antenna from C to Ku. Skip

Have you tried comming direct from the splitter and bypassing the disq sw? Try it on the Cband splitter with the AZbox set to off for the disq. You may have to do a factory re-set on the AZ. Iv'e had to do mine [prem hd, no blind scan] 3 times because of coruption. I now avoid pushing the buttons that caused the problem. I still have org. f/w 9.4585. I would like to change to newer f/w when I figure out how.

I hope this is the correct way? The IN cable in the photo is connected directly into the AZ. UPDATE. Nothing found with is method but I have G16-16 Shephards chapel 60 signal on my 920.
