    you must change the Step in the Bands (Parametrs -> Frequencies ) table from 25 to 1. Then all channels will be available.

    Good day!
    In the finished pattern of Frequency Bands for technology UMTS Band No. 1, prepared by Forsk for Atoll, only the first three carriers are shown (the beginning of the UMTS Band range No. 1), since this is an example of a pattern.
    Name DL Start Frequency (MHz) First Carrier Last Carrier Bandwidth (MHz) Step Excluded Carriers
    UTRA Band I 2 110 10 562 10 612 5 25
    The operator hasits own frequency band and the Frequency Bands pattern. You, as a radioscheduler, should prepare for your network.
    There is a totalof 12 carriers in the UMTS Band, with a band carrying 5 MHz.


    Name Uarfcn DL Downlink MHz Uarfcn UL Uplink (MHz) Bandwidth MHz
    F1 10 562 2112,4 9 612 1922,4 5
    F2 10 587 2117,4 9 637 1927,4 5
    F3 10 612 2122,4 9 662 1932,4 5
    F4 10 637 2127,4 9 687 1937,4 5
    F5 10 662 2132,4 9 712 1942,4 5
    F6 10 687 2137,4 9 737 1947,4 5
    F7 10 712 2142,4 9 762 1952,4 5
    F8 10 737 2147,4 9 787 1957,4 5
    F9 10 762 2152,4 9 812 1962,4 5
    F10 10 787 2157,4 9 837 1967,4 5
    F11 10 812 2162,4 9 862 1972,4 5
    F12 10 837 2167,4 9 887 1977,4 5


    Your case, withcarriers 10614, 10638, requires the use of the following values: Step = 14;Bandwidth = 2.8 MHz.
    I have not seensuch use of carriers in UMTS Band No. 1.
    Best Regards
