    Not reported as a beacon, maybe just a pure carrier


    s-band: can you confirm it ?

    I have the Ka B LNB fitted, which covers up to 20.7G, and I have calibrated the positioner using 19.2E but can't see anything. What is the signal around 20.2 on your plot?

    1.2m Prodelin 3122 az-el with one of:
    S: Helical feed, 0.8dB NF LNA, X: 1.2dB NF LNA, conical feed,
    Ku 12-18GHz: corrugated conical feed, 1.5dB NF LNA, Ku (Standard): SMW Q-PLL type C, Prodelin feed. Ku (Extended): 11.3GHz LO SMW & Prodelin Feed Ka: Gilat ex-ODU PLLs Gilat feeds, Ka 18-26.5GHz: Patriot feed, home made 4dB NF LNA, Ka DSN: Corrugated conical feed, home made 3dB NF Down-Converter

    1.5m IRTE, Polar mount with Octagon OSLO mod. C120, IRTE feed
    40km East of London, UK

    Yes, KA Band C pure carrier is off now (just checked) also nothing in Xband right now.


    The signal is a fake, this is always what I obtain when I start a CS with this LNB, forget it

    Here in circular left (using LNB for band B) - two wide TP appeared... not sure about exact position....? :28:

    They are similar here, about 120MHz wide and don't look quite like normal DVB and are not SBIRS-Geo. I need to calibrate the positioner to get an absolute position but they are a bit to the East at this time. I noticed a very strong carrier and a couple of weak ones around 20704R (Amos-17) between this pair and SBIRS-Geo.

    I think it is GovSat 1 at 21.4E. The magenta trace was is the noise reference but SBIRS-Geo was a few degrees above Govsat at the time. It is weak as it is RHCP. I left it to show the relative frequencies.

    My circular left scan. Next time I will try in circular right.

    PS: Merged latest reports above in this toppic - thanks s-band!

    Just my circular left scan, but nothing lockable, even not in S2X.
