Eurovox MMDS or cable??

    I ordered a Eurovox Max V 2008 cable box since I'm on NTL cable (or so I thought) in Dunboyne Co. Meath.

    But when I tried to set up I had problems (I've set up one before in another area, so I know how it works)

    I followed these staps...
    Step 1. Set up Powerscan to scan all freqencies (100 to 770Mhz) with three mbaud rates 6887, 6852 and 6875
    Step 2. It seemed to find 9 sources somewhere around 270 and 370 Mhz
    with QAM64 (I think)
    Spep 3. It the tried to decode these, but it reports that it is "unable to find channel"

    Now a neighbour of mine has a Dbox and it works just fine, he said that NTL use an MMDS link to service this ares, then drop it onto cable to feed the houses.

    Based on this info, the provider of the box recommmeded I try a Eurovox TX mmds decoded.

    But...Another neighbour had a Starview and it works fine also. So I'm confused I thought Starview is Cable box, not MMDS!

    Any advice please
    Thanks in advance...

    Eurov0x TX is for Chorus MMDS only

    If you have N*L then the EV Max V 2008 should work

    OK you need to go to menu, config, clear data and then clear channel data. Then do a normal powerscan from 290.000 to 403.000 using symbol rate 6887 N*L

    Make sure your cable is plugged into the RF Socket and not the antenna port

    Yep, did all that, powerscan, mbauds, RF socket etc...
    It found 9 transponders, but it could not decode them.

    It is remotely possible that Dunboyne is served with mmds through N*L cable?

    If my neighbours have Starview and Nokia Dbox;s that work, are these Cable or mmds?

    What do you mean with "cannot decode".
    Do you got around 95 TV channels from the scan or not?

    When I set it up in a different area (Rathgar)it works just fine
    It finds 9 digital transmission groups and then resolves the individual channels within... about 8 or 9 per group.

    But when I run a scan on my cable (Dunboyne) it does find the 9 "bands" but fails to detect any channels within each band.

    Can anyone tell if Starview and Dbox are mmds or cable ?

    You should differ between ntl mmds and chorus mmds.
    Ntl mmds is simple cable technique over the air.
    It looks like the signal strength is too weak at your feed in Dunboyne.

    Yes I'm definitely on N*L cable I've got the basic service (about 13 channels).
    The singal quality on the basic channels is near perfect.

    So I'm not sure poor singal qiality is the problem, and my neighbours have digital receivers that work just fine, as mentioned before.

    So can I assume that changing my Eurovox MaxV to a TX will not solve the prolem ??????????????????

    The tx box is for chorus mmds.
    If you get the basic analogue channels its not ntl mmds.
    Check if your neighbours can get the analogue channels via the tv tuner without ntl box.
    If not you and your neighbours are connected to different networks.

    Yes, neighbours gan get standard N*L basic package.

    The neighbour with the Nokia Dbox had to select "N*L MMDS Bruteforce" before he could get it to work.

    When my scan completes, the config menu shows this list...

    001 258.000 Mhz 6887Mbaud QAM64
    002 274.000 Mhz 6887Mbaud QAM64
    003 290.000 Mhz " "
    004 306.000 Mhz " "
    005 322.000 Mhz " "
    006 338.000 Mhz " "
    007 354.000 Mhz " "
    008 370.000 Mhz " "
    009 386.000 Mhz " "

    Does this much look right so far?

    These don't seem to match this list for N*L frequencies...

    Perhaps I should do the poswescan with a step of 1 and not 8???

    Thats a transponder list which match ntl mmds and not true cable.
    Do you get any analogue channels without any box only via the tv tuner?

    Yes, I get about 13 stations on the TV tuner without any decoder or external box.

    Could I have mixed service from N*L....i.e. bacic analog TV on cable mixed in with MMDS on the same cable ????

    If thats the case, do I need a Eurovox TX instead?

    Once again. A tx box is for chorus mmds.
    The chorus mmds subscribers got a sagem box for digital.
    Maybe analogue is mixed with ntl mmds at the cable headend in your area.
    If you get a perfect picture for the analogue channels maybe the signal is too strong for digital.
    Try something to decrease the signal strength. You could use your video for instance and route the signal via rf in and to the box via rf out.

    OK, won't mention TX box again.

    I have a S0ny HDD recorder that I can pass the singal through to attenuate it a bit, i'll give it a try... thanks.

    I think I found my problem.... poor signal quality

    When I look at the "level" and "Quality" I see about 80% to 85% on each. The signal also seems to jump around a lot, dropping to 0% for some moments.

    So I removed some splitters and made te signal as pure as possible(direct feed from N*L cable socket) the re-scanned.

    This time it managed to identify channel names like Sky 3, and some radio stations etc...
    It also managed to reslve 'some' programme name's that were being shown.
    But when it tries to un-scramble the channels it comes back with "no signal"


    I turned on the RF booster in the config menu but it made little difference..

    Any advice, would an external booster help... or am I waisting my time and the problem is low quality feed form N*L?

    A amplifier could solve the problem.
    Which one depends on the installation.
