    Dear all,

    I haven't found many people on the air using Kurt's software, so I decided to bother you on this forum.

    I have been wondering whether my receive path is good enough. The signal levels I get with the AMSAT-DL software on the narrowband transponder with RX bandwidth = 2.7kHz are:

    • Lower beacon: 29dB (when there is no Morse).
    • Middle beacon: 22 to 23dB (0Hz centered on response null).
    • Upper beacon: 22 to 23dB (beacon centered on 2.7kHz receiver bandwidth).

    Are these numbers realistic or is my receiver deaf?

    Any replies or opinions would be most welcome. Thanks!

    Hallo,


    Ich möchte einen Othernet Bullseye LNB mit folgendem verwenden:

    • eine Standard-POTY-Antenne (22 mm Kupferrohr) und
    • eine externe 25-MHz-Referenz, weil ich meinen sehr stabilen 25MHz OCXO (5V Rechteck) verwenden will. Ich möchte den ursprünglichen TCXO des Bullseye entfernen und 25 MHz in den roten F-Anschluss einspeisen.

    Hat jemand eines (oder beides) der oben ausprobiert? Ich wäre Ihnen sehr dankbar, wenn Sie Ihre Ideen und Erfahrungen teilen würden.


    Dear all,


    I plan to use an Othernet Bullseye LNB with

    • a standard POTY antenna (22mm copper pipe end) and
    • an external 25MHz reference feed, because I have a super-stable 25MHz 5V squarewave OCXO I want to use. This would mean removing the Bullseye's original TCXO and somehow feeding 25MHz into the red F-type connector.

    Has any of you good people tried either of (or both) the above? I would be truly grateful if you would share your ideas and experiences.


    Vy 73!
