Говорят, что KP4AO можно услышать на маленькую ручную яги направленную на Луну, а сработать телеграфом на одну стрелку и 100 ватт.

** Arecibo on 432 MHz Moon Bounce **
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.
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 linearly polarized antenna and 100 W will be enough to work
us on CW. KP4AO will be circularly polarized, so polarization lockout will not
be a problem.
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.
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.
