    Hi . @Captain Jack ...
    no i,m afraid not .. even though its a superb day here today .... this dish has been chained down for weeks now with all the recent windy weather ... out mountain/ fell walking this afternoon and tomorrow .. then working sunday ... maybe i will get chance to continue something with this dish on monday i hope ... .. the last thing i did was fitted a combined ku/ka lnb and had a bit of a play around just before the bad weather closed in.
    cheers :)

    Morning ...
    Good result with 1.8 ... into F15 and V7 .. smooth picture (no breakup) :)
    2.4 has no l.n.b. on currently ... going to play with an old co rotor on that dish later, after work.

    Hey Nelson, any chance of a quick try on 36e Russian beam on the 1.8? I still haven't tried the plate you sent but hopefully over the next few weeks.

    Thanks guys, I think this is from the Mena beam ? not NWA its far to strong compared to other NWA transponders.

    Hi -- C.J. ... not looked there for ages ... will look with the 2.4 first (easier to setup for test ) and check the signal strength etc. if all looks good enough i will try with 1.8 :)

    Hi C.J. ... i had spare time Saturday afternoon so had a check on the Russian beam with the 1.8
    when the skies are cloud free as they were on sat afternoon i,m able to lock (just) ---
    the same 3 transponders as before ... not a hint of signal from any others on the Russian beam though ..
    the signal gets a little stronger late afternoon/ early evening. when i took these levels with the F15

    12 130 R 27500 .. 8.1 db
    12 092 R 27500 .. 8.8 db
    12 149 L 27500 .. 8.3 db
    Needs 7.9 db for lock (Lyngsat)

    with the 2.4 all readings are a full 1.0 - 1.2 db higher

    pic below of the - l.n.b - feed - plate - orientation that i used .

    This is the only TP I get any sort of signal from on the Russian beam - without the plate in yet. I suspect the plate isn't going to go far enough to get a lock on this.

    Hmm -- Got to be worth a try with the plate i guess ...
    but i must admit it doesn,t look very promising ... maybe i,m just in an unusual hot spot here.

    Took advantage of the sunny weather to try this with a plate. This time, all the Russian beam frequencies you receive come in at about 2.5dB - obviously waaay below what's required for lock. I have a better chance of 56e down here but not until I relocate the dish slightly... and that probably won't be enough.

    What a pity -- perfect weather for a best try ... but yes judging on the result without a plate --- your result with a plate is about what i thought it probably would be:( .. the plate i sent you is as good virtually, as an original one too - only 0.1 db less on my setup.
    can only assume that i,m in some kind of odd hot - spot here then ?

    anyone else in the uk able to get a lock on these 3 circular k/u transponders ?

    Yeah it doesn't help the fact that there are sub-Sahara beam transponders on nearby frequencies creeping in. I put the LNB at a 45 degree angle to try and eliminate them but with the plate in, it seems to come in on both polarities. Is that the best position for the LNB?

    Hi -- I have it setup on the 2.4 currently .. as in pic 3 and 4
    here are some pics of positions and 1 of the feed with position of probes in relation to plate marked in red pen
    if i skew the whole issue as in the second pic i gain about 0.1 -- o.2 db
    i get signal on both polarities from
    12 130 and 12 149 but only 1 polarity on 12 092?
