I posted this question in the FTA section, PBS and Iceberg answered my initial questions about using the elliptical dish for 121, but I think it fits here. Currently, I am using an elliptical Hughes dish (21" x 36") with a circular LNB to get the dish network international from 148, I am getting about 95-113 on the different transponders using a 3900 receiver. For the 110/119 I am using a dish 500 with a dual DSS LNB and both feeds are switched with a SW21.
Now I wanted to use the 121 instead of the 148 so I tried to replace the circular LNB with an FSS LNBF (Zintech ZKF-F22, R.F. 11.7-12.2 Ghz, IF 950-1450 Mhz, L.O 10.75 Ghz) using the 21"X 36" dish and adjusting it to face 121. Now here are the issues: the 3900 setup when I chose 121 it mentions wrong satellite dish network 119 despite it shows a 95 signal but red. When I chose 148 it displays wrong satellite dish network 121, 85 signal but red. Checked the switch which never detected the 121. Also I reseted the 3900 receiver but couldn't get the 121 to turn green. what am I doing wrong? the 3900 is upgraded and displays the dish 500 and superdish.
Any help? Thanks.

also if you have a signal meter.. point with that and then run a line straight to the receiver. do a check switch to see if it recognizes 121. If it doesn't then your off some where. if it does fine tune it from there... remember fss signals are 2 degrees apart from other birds unlike the 9 degree spacing from dbs so it is quite possible that your on another bird. when you point your dish and if the check switch comes back on to 119.. with the dish hooked directly up to the receiver then you also have gone to far east. its smack dab in the just a tad bit to the right of 119
