> Hi all:
> Here is a EME event you cant miss.
> Dust off your CW key, its time for Satellite, QRP EME.
>
> The 1,000 foot dish has 60 dBi on 432 mc and 400 watts.
> That comes out to be approximately 243,902,443 Million Watts ERP.

> Arecibo on 432 MHz Moon Bounce
>
> The Arecibo Observatory Amateur Radio Club will be putting the
> 1000-foot radio telescope<\/span> 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
> CW.
>
> 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!
