KP4AO


E.M.E. from Arecibo - KP4AO





    Three days in april, 16,17 and 18 the "Big Gun" antenna from famous Arecibo radio astronomy observatory  was take over by radio amateurs for a special event; an E.M.E. radio transmission involving a lot of radio amateurs all over the world.

............................................................................

    Thanks to my low power TX i chose to take part at this event like SWL. My equipment consist in a 15 elements Yagi antenna on an astronomy tripod pointed from window to the moon, BFG65 preamplifier conected to Yupiteru scanner with 3m cable.
  • 16.04.'10 - a lot of ham's from my area try to catch the echo but nothing to hear. Next morning we found out that they have problems at Arecibo with PA and they push in the dish only 25W.
  • 17.04.'10 - finally in the evening the signal come, not so strong but very clear. KP4AO with 54-55, very good copy with low noise. I hear also few other stations the most powerfull was a RA at the same level - about 55. During clouds passes was a strong qsb with signal level going down to 32.
    This type of experiment is a great opportunity for testing small equipments and even trying qrp contacts.
    Congratulations to everyone who made qso with KP4AO.
