    Default ON0EME 1296 MHz Moonbounce Beacon

    ON0EME 1296 MHz Moonbounce Beacon

    This is possibly the first amateur radio beacon to beam signals off the Moon. It's aim is to encourage people to try and receive EME signals.

    According to a report in 432 and Above EME News the idea started in Orebro, Sweden during the EME meeting in May 2011. After about 11 months of intensive work by ON7UN, HB9BBD and ON4BCB the beacon ON0EME started transmitting on 1296.000 MHz in the direction of the Moon.

    ON0EME’s total EIRP is about half a megawatt. The antenna is a solid 3.7 m dish and it is active when the Moon is >10° at its location.

    The system is completely automatic. The beacon starts when the moon is on the east side +10 degrees, by turning the antenna from the point where it stopped the last Moon pass (Moonset at +10°).

    The frequency is GPS locked at 1296.000 MHz with an accuracy of 3 x 10-11. The timing is also GPS controlled. The beacon will start transmitting at the minute. The amplitude of the signal is constant within ± 0.2 dB. Antenna pointing is updated every 0.4°. There is complete remote monitoring and control of the beacon with indication of voltages, power and temperatures.

    Reports have been received from some small stations receiving the beacon. Please post reports on "moon" or the "moon-net" reflectors.

    The beacon is located in the north of Belgium and has good Moon visibility at both high and low declination for the complete Moon pass.

    Users can check the operational status and beacon parameters at the ON0EME Status Page http://www.on0eme.org/

    HOLY !@#$ That is a lot of ERP!
    FAAAAAAAAAAAAAAAAAA!!!!!!!!!!!!!!!!!!!!!!!!!

    500 KW out the antenna!

    MORE POWER!!!!!!!!!!!!
    Good luck to the Swedish amateurs up there. They got a beacon for sure.
    I guess the hard part was all the automation of that big dish.

    More power to them. Literally!

    SETI Had an EME beacon at one point http://www.setileague.org/eme/status.htm

    Sure hope that doesn't push the moon out of orbit. The cow might not be able to find it.

    pump-it-up!
    Chips all run on smoke. Inside every chip is a little tiny supply of smoke that keeps it running smoothly. When you screw something up and let that little puff of smoke out of that chip it WILL quit working. That's an etched in stone fact of life..

    A fine is a Tax for Doing Wrong, A Tax is a Fine for doing well.

    Screwing up is one of the best learning tools, so long as the only thing you're not learning is how to screw up

    Hold on, I'll send a report shortly. I will be using my Kenwood TH-F6a and the rubber duck. With that kind of ERP, I should hear it no sweat.

    nice to see , but not the first.
    SETI guys had one on 1296.000 with automated tracking , Downeast Microwave provided the amp and antennas were 4 helixes cophased 250w output into phased array.
    later to be replaced with a Kuhne amplifier . I beleive it's inoperational now.

    500 thousand watts? Nah, that has to be a typo. If it's not, its idiotic. and dangerous.

    What is idiotic and dangerous about it ?
    Legal power with the gain of a dish antenna = lots of ERP pointing up at the sky, operated by technically competent and responsible persons.

    Lee, it's EIRP not actual transmitter power. http://www.antenna-theory.com/definitions/eirp.php

    Pretty impressive work by the guys in Sweden. I'm going to have to look in to what it would take to receive them here in the states...
