    I've put this in the data section as I can't identify most of the signals, they are only just above noise. Some that appear to be GS on RHCP are shown here. It looks like the UK is outside the service area.


    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.

    Things have changed since yesterday. I can no longer see the group covering 19.2-19.35GHz or the carriers around 20.7GHz (LHCP). However, the lower level carriers on 19700.5MHz and 20199.5MHz are still there. THere's a new signal on 19329LHCP which looks like BPSK on CS constellation but the spectrum is unusual.


    On RHCP, I can only see two carriers, one on 20199.5 and the other on 19700.5MHz. I guess that these carriers may be linear polarised. Can anyone check, please?

    Thank you s-band for your reports! :76:

    I tried these days too on both polarisation, but I cannot find any peaks. Here my current circular left scan. :33:

    Circular left scan - nothing lockable (even not in S2X).

    Band C also active at this time.

    Lediglich ein kleines Rechenspielchen. :26.

    Es gibt -mathematisch gesehen- ein paar "Häufigkeiten" bezüglich der SR (=die unterstrichenen Werte).


    Just a little arithmetic. :26.

    There are -mathematically speaking- a few "frequencies" regarding SR (=the underlined values).


    Zum Beispiel/for example: :101:


    29152 = 1214 2/3*24 = 1822*16 = 2429 1/3*12 = 3644*8 = 5466*5 1/3 usw./and so on


    1712 = 428*4 = 856*2 usw./and so on


    Drei der häufigsten "Trefferfrequenzen"/Three of the most common "hit frequencies":

    19231 L / ~19274 L / 19312 L

    I start a try in circular right (I think)...

    Just another circular left spectrum, using "band B" LNB at this time.


    Just in circular left spectrum in summer 2023, using "band B" LNB.


    Zitat von qwer

    Just in circular left spectrum in summer 2023, using "band B" LNB.

    ...no changes in september.
