432 eme

I guess I could put this under "Guns and Hams" but this is more appropriate. Just received this email:

In less than two weeks the Arecibo Observatory Amateur Radio Club will again put
the 1000-foot radio telescope on the air for 432 MHz EME. 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.

I think "Large cannons and hams" would be more appropriate.

Pretty neat. I'd like to at least hear them. I'm not currently equipped to work them, however.

Last time I listened to anything off the moon was HAARP on 7 mhz.

Wow!! 400 watts and 60dB would generate an ERP of 243,902,443.89466 watts. Talk about heating up the clouds!

We have them right here in New Jersey. Battleship New Jersey Amateur Radio Station

Same here, & got my QSL card too.

I will listening with my Arrow yagi.
