[Fourlanders] FW: [Mw] April 17 World Moon Bounce Day

[Jim Worsham]

Is anyone going to be trying this?  The moon is going to be fairly high in
the sky so an antenna on an az el mount will be required.  I know at least a
couple of the guys in the group do the sats and have antennas on az el
mounts.

It doesn't matter how beautiful your theory is, it doesn't matter how smart
you are.  If it doesn't agree with experiment, it's wrong.

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.

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!

Paul,N2GHR, reports working KP4AO (Aricebo Dish), on 432 Side band, using
500-W and a pair of RIW-19's on a small tripod in his backyard, - "armstrong
rotor method"! Listen to his audio clip at:
http://www.newsvhf.com/audio.html and scroll down to KP4AO or,
http://www.newsvhf.com/kp4ao-n2ghr.mp3

 Aricebo is 1,000 feet across and has a gain of 60 dBi, so a modest 432 SSB
set up can hear it.  Dale, AF1T is rebuilding his 432 Amplifier to try to
make a two way contact on Friday April 16th.  We will leave for the Eastern
VHF/UHF Conference in Enfield, CT, right after the attempt.  Dave Olean,
K1WHS, is bringing his big 432 set up to make a two way contact at the
Conference.  For those interested in participating, see:
http://www.newsvhf.com  to sign up for the conference.  It is just across
the border from Springfield, MA. ( -At the next exit down from
Enfield/Longmeadow, are several inexpensive hotels.   We usually stay Friday
and Sat. nights, returning after the Ham Flea Market on Sunday morning.)

Anyone interested in hearing Aricebo send echoes off of the Moon, can use
their hand held SSB radio The window to Peuto Rico will be open on Friday
from 12:45 to 3:30 PM, one hour later start and stop time, on Sat. and one
hour later on Sunday

  If you have never heard signals off of the moon, here is your chance,
