    Hi, I have 2011 Foxsat set. Over this new year I’ve lost a number of common channels although they are still listed in the channel list. I’ve contacted Freesat who told me to do a factory reset which I have done. I have shut down and unplugged the unit for a period.I have disconnected and reconnected the aerial wires. Humax help staff told me to take the unit to another household with a Sat dish to confirm if its the unit or my dish.

    Its all rather odd regarding the missing channels. Most of BBC’s HD and ITV HD have gone. My local BBC south SD channel has gone. BUT I can get BBC HD Wales and BBC South East SD for example! MORE 4 has gone but MORE 4 + 1 is available!

    I’m not a techie but the above seems weird. Should I get a dish engineer in or is it my unit? Should I put in a fictitious post code and pretend to be in another area? Many thanks for advice on this.

    Hi welcome to our forum.

    Your symptoms could have a number of causes. The most likely is

    1 Water is getting into the coax cables

    2 Water has corroded the lnb connections

    3 The lnb is failing.

    All of these require access to the dish. If it’s low down and easily accessible then it’s a fairly simple diy job.

    If not then get a dish fitter to look at it.

    If you download and print the Freesat transponder list in .htm format from here,

    https://myhumax.org/forum/topic/what-can-i-record-and-watch-using-1-or-2-cables

    And tick the ones you have lost may be able to spot some sort of pattern.

    Had another thought. Is your box truly a Foxsat-HD (single tuner non recording) ?

    Hello Graham, sorry if I had been unclear, It is a Foxsat-HDR Model number FOXSATPVR-2-40715.

    Regards.

    Should have been posted in Foxsat-HDR.

    Graham posted a link to his transponder list above.

    Question: Can you receive any of the channels with a V in the Polarisation column (vertically Polarised).

    If not it suggests a LNB fault. There is a very small chance (very rare) that the Foxsat is not switching correctly but that would be very rare.

    Other than Repassac’s suggestion all the other’s either require access to the dish or connecting your box to a friend/neighbours known working dish.

    Had it been a Foxsat-HD it could have been a known issue with the power supply capacitors (The Foxsat-HDR isn’t affected).

    How do I see if there is a V in the polarisation column please, where do I look? Also what is a LNB fault please?

    Have you got the .hmt file on your PC from

    https://www.adrive.com/public/t3jBkt/FoxsatStaticMK2_011.htm

    Once you have open your web browser and using the File menu open the downloaded file.

    If you have excel (or a compatible spreadsheet) you can download the

    Excel version

    You should see a table that looks like this.

    [attachment=63489,932]

    Look at the first 4 columns they are seperated by coloured blocks. Each block is a satellite transponder. Each transponder carries multiple digital channels all mixed (Multiplexed) together. When you select a freesat channel, the tuner you are using in your box extracts that channel and shows it on your screen.

    Column 3 shows the microwave frequency used by the satellite for those channels and Column 4 the polarisation (Horizontal or Vertical). The total frequency band is split to form Low Band and High Band channels. Column 5 indicates the polarisation and Band.

    Example 104 Channel 4 uses 10714Mhz and is Horizontally polarised and is Low Band (LBH – Low Band Vertical).

    Your task is to choose one channel from each coloured block and note which ones you can still use.

    The lnb is the box on the end of the dish arm from which the coax connections come from.

    Very briefly it collects the microwave frequencies reflected from the dish face and converts it to lower frequency that can be sent down the coax cables to the satellite box tuners. LNB is short for low noise block down converter.

    Read this primer it explains how the satellite tuner switches the lnb between horizontal and vertical polarisation and between low band and high band.

    Regards.

    A LNB is the device at the end of your dish’s arm. They are inexpensive and easy to replace.

    Shouldn’t that be LBH?

    OOPS – of course it should, as in the table. Thanks Martin post edited.
