Rx Band Start, Stop & Step Size:
--------------------------------
10950,11450,1,
11200,11700,1,
11700,12200,1,
12200,12750,1,

Equivalent Start Frq,Step:
--------------------------
10900,1,
11150,1,
11650,1,
12200,1,

Calculation Formula:
--------------------
Gen_RxFreqChNum = Hex((Freq - Rx_Comm_No(FreqBandOption)) / Rx_Comm_Dem(FreqBandOption))
Where:
Freq=Desired Freq
Rx_Comm_No(FreqBandOption)=Start Frq of the Band
Rx_Comm_Dem(FreqBandOption)=Step Size(MHz)


Summary:
Freq  Band Range, Channel Num of first freq:
---------------------------------------
10950~11450:	50
11200~11700:	0
11700~12200:	50
12200~12750:	0

Therefore, if using LNB 10950~11450, set receive freq to 10950 (first freq, channel 50),
there will be 70MHz IFOut if there is 10950 signal pump to the LNB.
With the SAME setting, if replace the LNB with 11700~12200, there will also be 70MHz
IFOut appear if there is 11700 signal entered to the LNB.
