DATV using DM800SE

    I have a DM800SE with BCM4505 tuner which is specified down to 1Ms/s.


    I have an SR Systems TX on L Band and 437MHz which in theory will go below 2MS/sbut I cannot get the dM800 to lock below 2MS/s.


    Qu 1 Has anyone any exprience locking below 2 MS/s on DVB-S? we see French stations at times and they run 1.667 or 1.024 Ms/s


    on 437MHz.


    Qu 2 The BCM 4505 tuner spec sheet says is covers 250 to 2150MHz , I would like to use the IRD directly on 437Mhz. Is there a setup method to set the LNB frequency to zero to use the input directly at 437 or L Band. Is there some edit software to load my frequencies etc?


    thanks in advance peterB g3pyb

    There shouldn't be a problem locking signals with symbolrates below 2000Ms/s, I've locked many feeds with symbolrates below 2000Ms/s and also some below 1000Ms/s (~500Ms/s).
