    Question interfernce caused by an unknown transmitter!!!!!!!!!!!!!

    hi everyone, i have a 3.7metre dish here zinwell 15 k lnbf cband feed currently only. ,my receiver is a octagon 518 with a diseq 1`.2 motor positioner.the problems im having have just started again that is my receiver is being flooded with some type of unidentified transmitter with an unknown origin here my system has been working excellent for months until tuesday of this week .the interference returned again its taking out nearly all the horizontal transponders on every satellite except ku even some vertical transponders are being affected, but 90% of the horizontals are being wiped out with this unknown transmitter. i did replace the f connector when it was doing it it seems to have helped abit but it seems that asiasat5 cband is the worst affected ,can anyone give me some advice on this on how to combat this if i can ,thanks hamguy2 nsw .

    Foxtel have a special counter strike targeting you.

    Have you seen the black helicopter overhead lately with a ray gun firing at your dish?

    Sounds like interference to me.

Im not to sure were it is comming from and my system has been working perfectly for months. The interference seems to be effecting nearly all the horizontal transmitters on every sat except ku(??), some vertical transponders are also effected.

    I did attempt to fix the issue by replacing the F connector, which seemed to have helped a bit. Asiasat5 c-band is by far the worst.

    Can anyone provide any advice or assitance on this issue?

    Thanks

    Just messing with you ,

    Maybe the dish is out of alignment? How do you know its a "transmitter"?

    If it's all horizontal transponders on all satellites, on different frequencies, I'd suspect an LNB fault.

    That's exactly what I was about to suggest.

    Also, try turning off appliances etc, to see if one has some spurious emission.

    I've seen everything from a faulty power supply in a VCR, and motors in aircon units and even faults in garage door openers cause otherwise 'unexplained' interference/loss of reception.

    The broadband cable signal itself shouldn't be causing any interference issues, but wireless possibly could.... or any other electronic device that's gone spurious.

    It sounds like interference either from Wimax or radar , thanks to the powers that be selling off C Band spectrum . One of these should fix it


    Chops out the interference in the 3.6ghz range .

    Yeh it sounds similar to the problem I'm having were the signal is so strong that it saturates the AGC & causes the front end of the receiver to shutdown until the interference is gone only to repeat its self over & over.

    I am preparing to move the dish to a more shielded position hoping that fixes it.

    In My case I have a similar LNB to the 1 in the sattronics link & it didn't help.

    good luck & please let us know if you resolve the problem.

    That's what it sounds like to me.
