    I just found it but it went off at around 15:30 UTC, before I could get a plot. Plain carrier.

    Quite strong on a band B, circular pol, LNB (21.4G is about 10dB down on in-band performance)


    <edit> Back on at 1545 but at ~20dB lower level

    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

    Confirm lower level right now.


    /edit: ...and strong carrier a few minutes later.

    I left the analyser running for 30 minutes, set to maximum hold. The stepped nature of the plot is due to aliasing between the TX sweep and analyser sweep rates. The actual sweep rate of the TX was quite fast.

    Still using a band B circular pol. LNB
