EME QRP auf 70cm

  • Hallo zusammen,

    im Folgenden eine Ankündigung der AMSAT für das kommende Wochenende. Das sollte auch nur zum reinhören interessant sein.

    Viel Spaß

    Gruß Holger

    Arecibo on 432 MHz Moon Bounce

    AMSAT News Service Bulletin 101.06


    April 11, 2010


    BID: $ANS-101.06

    The Arecibo Observatory Amateur Radio Club will be putting the

    1000-foot radio telescope on the air for 432 MHz EME from April 16-18.

    It can be heard with a small hand-held yagi pointed at the moon

    The scheduled times of operation are:

    April 16: 1645 - 1930 UTC

    April 17: 1740 - 2020 UTC

    April 18: 1840 - 2125 UTC

    Callsign: KP4AO

    Tx Frequency: 432.045 MHz

    Rx Frequency: 432.050 to 432.060+

    Tx power: 400 W

    Antenna gain: 60 dBi

    System noise temp: 120 K (cold sky)

    System noise temp: 330 K (when pointed at moon)

    KP4AO can be heard with a small hand-held yagi pointed at the moon and a

    good receiver. A 15 dBi antenna and 100 W will be enough to work us on


    Operators at KP4AO will do their best to work as many stations as

    possible. Each session will start with a brief announcement and CQ in

    SSB. SSB QSOs may continue for 30 minutes to an hour, if the QSO rate

    remains high.

    The mode will be shifted to CW as soon as it is judged that higher QSO

    rates would result.

    We will listen for calls at frequencies 5-15 kHz higher than our own,

    and even higher if QRM warrants. Callers who s-p-r-e-a-d o-u-t are more

    likely to be copied.

    If you've already worked us in any mode, please do not call again --

    give others a chance.

    If we call "CQ QRP", we will listen for stations running 100 W or less

    to a single yagi. Please do not answer such a CQ if you are running more

    power or have a larger antenna.

    On April 18, if we reach a condition where most calling stations have

    been worked, and we judge that operating in the digital mode JT65B would

    produce a higher QSO rate, we will switch to JT65B.

    Note that any of these planned operating strategies may be changed as

    circumstances dictate.

    We are extremely fortunate to have been granted access to the world's

    largest radio telescope for this amateur radio good-will event. We look

    forward to working as many stations as possible in the alloted time!

    [ANS thanks John, KB1MGI, for the above information]


  • Hallo,

    Hab den Beitrag auf der FA Homepage gelesen. Ein Funkfreund und ich haben vor da mal mit einer 10 Ele. DK7ZB Yagi reinzuhöhren. Naja für SSB und CW wirds wohl nicht reichen höchstens als SWL'er. Sendemäsig werden wir es auf alle Fälle am Sonntag Probieren ich denk mit JT65 haben wir mehr Chancen mit 75W an der Besagten Yagi.
