Manual channel search, modulation variable handling

    Hi


    == No cleared variable ===
    Manual search:
    - select DVB-S2
    - select 8PSK
    - select DVB-S
    - do scan, the status line shows "8PSK" not QPSK


    == Un initialized variable ===
    - exit and do the manual search again, with defaults. The 8PSK is still show
