You will have to delete and rescan the TPs with 22Khz OFF and a new LNB profile of a single LO (hopefully 9750) to log the transponders are on a tuneable IF (950-2150Mhz). Do not set the 22KHz ON or it may or may not set the LNBF to the upperband (LO 10600).
The purpose of this test is to eliminate the 22Khz tone and possible LNBF band switching errors from the equation. Transponders below 11900Mhz are able to be tuned by all DVBS receivers (typical IF tuning range 950-2150Mhz). If the receiver is left in the LNB type Universal, the band switch point between low band (10700-11700 @ LO 9750) and high band (11700-12750 @ LO 10600) happens automatically at 11700Mhz. In Standard type LNB setting with one LO, no switch point occurs as there is only one band.
In theory, the receiver will be able to retune without issuing a 22KHz tone. Here is the math: 11900 Mhz (transponder downlink frequency) - 9750Mhz (LO frequency) = 2150MHz IF (Intermediate Frequency).
