Tonight at about 04:30 UTC March 10 the 24 GHz EME signals of W5LUA were
heard at VE4MA. Signals were weak at both ends. Al's signal here was T-M
copy.
I am using an 8 ft offset (14 /12 GHz) dish with a "large" diameter W2IMU
feed into a DB6NT preamp at 1.55 dB NF. I see 15 dB on Sun noise and 2.3 dB
of moon noise. I had no visual moon because of clouds, but this does not
appear to have affected the moon noise. The beamwidth of the antenna
appeared to be slightly less critical with clouds than with clear sky.
The WX here was about -1deg C (warm spell!)and about 80% humidity with snow
expected overnight.
And now to make a QSO

Joe thank You for putting me on the NET NOTES I enjoy reading the notes
I will be getting on 23cm EME as soon as I get my 2m ants up.
It might be 2 to3 months but I will be there!!
I wonder if I will be able to work many stations Rether than the BIG BOYS.
Is the 10 ft dish and 300 watts like having 4x18lxxx on 2m will that be the same??
I willbe there someday
tnx and 73

Sender: [email protected] (Paul Chominski)
To: [email protected], [email protected]
Al and Joe,
WA6PY was on 13 cm March 2-4 and QSO'd in skeds: OK1KIR WA8WZG F2TU
LX1DB and also OE9ERC and OE9XXI cross band Peter was on 2320 MHz. Heard
very loud OZ4MM. I have now 10 initials on 13 cm and 26 on 23 cm. On April
30 / May 1 I will be QRV on 10 GHz if my old equipment is still working.
I am not sure if I will be QRV for Arecibo SETI test. I have additional 13
cm skeds with JA8IAD on March 10 and 11. At present changing feed and
equipment takes several hours, and I am afraid that without sun noise
measurements I will not be able to optimise my 13 cm system for this sked.
I will send my time and sked request later during the week. I am looking
for WA7CJO W5LUA AA5C DJ7FJ G3WDG G4KGC OK1KIR OE9ERC PA3CSG IK5WJD
and all other active stations. I understand that activity on 10 GHz will
be low due to the EME contest on other bands.

My first lunar echoes on 24 GHz by W5LUA
I was finally able to hear and record my first earth-moon-earth echoes on
24192.1 MHz at 0816 GMT on March 7, 2001. My antenna is a 3 meter Andrews
prime focus dish. According to Andrews, the 3 meter dish is rated to 30 GHz
with proper back structuring to optimize the dish's surface. The dish really
began to perform when I added a back structure which looks like a
tic-tac-toe board mounted to the backside of the dish. The eight points of
the back structure allowed me to optimize the dish's surface by pushing or
pulling on the back of the dish to enhance the accuracy of the dish's
surface. The end result was improved sun and moon noise. I presently receive
12.5 dB of sun noise and 1.3 dB of moon noise. My feed is a scalar feed
optimized per the "W1GHZ On-Line Antenna Handbook". My dish has an F/D of
0.3.
My LNA is a 2 stage W5LUA homebrew design using a pair of Agilent
Technologies PHEMT devices which provided a 2.25 dB system noise figure. My
basic transverter is built around surplus 23 GHz modules which down-converts
to a 2304 MHz IF which is then down-converted to a 144 MHz IF with a Down
East Microwave transverter to an ICOM IC-271 transceiver. I was able to
achieve about 20 watts at 24192 MHz by re-tuning a Varian VTU-6191 14.5 GHz
TWT which I have been using on 10 GHz EME at about 80 watts output.
Re-tuning consisted of lowering the Helix voltage and doing some tuning in
the output waveguide section.
I was using Mike Owen's Realtrak Software to track the moon. I was concerned
about the accuracy of the doppler calculation of the various moon tracking
programs which I have used in the past. With an expected doppler of up to 50
kHz, there is not a lot of margin for error when tuning for echoes. I ran
some echo tests on 10368 MHz and came to the conclusion that Mike's software
was the most accurate at 10368 MHz. I therefore placed my confidence in his
software at 24192 MHz. Based on the doppler shift of the received echoes, I
believe Mike's software predicted the returns within a few hundred Hz.
On the evening of March 6 local time I had just installed my elevation
rotator which allowed me to remote operate the dish from the hamshack.
Previous attempts at echoes were with all equipment mounted in a shed near
the dish. I had tried for echoes prior to zenith but only thought I had
heard echoes. Some clouds were beginning to cover the moon so I decided to
set my alarm clock for about 2AM and give it a shot on the setting moon.
First discernable echoes were heard at 0816 GMT with the moon at an azimuth
of 268.8 degrees and an elevation of 38.8 degrees. The doppler shift at this
time was a negative 45.3 kHz. Echoes peaked very well at 0848 GMT where the
elevation was down to 31.5 degrees and the doppler shift was a negative 49.1
degrees. At this point, I ran out of azimuth control with my present set-up.
My lunar echoes peaked Q5 (M copy) in a 2 kHz bandwidth and were easily
identifiable on AF9Y's DSP software. This triumphant event came after
several years of optimizing the system and many failed attempts at achieving
lunar echoes. I was rather surprised to find that the echoes did not seem to
be much broader than my 10 GHz echoes, maybe due to the 0.3 degree
beam-width of my dish.
More information including the AF9Y .gif files will be posted on the North
Texas Microwave Society web page at www.ntms.org
Now to make a QSO!

Joel -- I just read in the ARRL newletter that the league is recommending that
it would rather see SAVI put part 15 stuff in the 902 to 928 band. What Kind
of CRAP is that!
Here is the quote --
"The ARRL characterized SAVI's petition as another in a long series in which
manufacturers of unlicensed RF devices seek to liberalize rules regarding permitted
field strengths for such devices in bands allocated to the Amateur Service.
The League said SAVI obviously did not have interference avoidance in mind when
it chose the 420-450 MHz band. "t is among the worst choices SAVI could have made
from that perspective," the ARRL said. The League suggested that SAVI would be
better off deploying the devices in the 902-928
MHz band.
I thought the ARRL worked for US ? Why are they giving away one of our best bands?
And who gave them the right to make this d umb recommedation anyway?
I am not happy that someone back there thinks that they can give sacrifice spectrum
on any of our bands, This is completely uncalled for anf I think this recommendation
should be pulled and the person who said it reminded that we use this band.
We don't need MORE INTERFERENCE !!!

Hi Bob and others,
I am sorry that this is going the way it is. I have certainly tried
to get the word out. Perhaps though, you can send me some more
details.
You know most EME'ers live for one thing, initials, many of them
are not interested in science or experiments. As a matter of
fact this is what amateur radio is all about for many anyway.
On the other hand the information from Aracibo also lets a lot
to be desired.
If I know the details, times, what want they to be done, a
description of the experiments etc I will push the issue more even
at the risk of making enemies.
Moonbounce is not taking a HT out of your pocket and saying"
"So and so Monitoring" It often needs planning reading the
antenna, moonvisibility and othet parameters
I need to know details so that I can contact people I know
and send them details.

This is the original message from Al that I have distributed over

channels: ( Rein )

The SETI League with be conducting a weak signal EME test with the
Arecibo radio observatory at the following times - see announcement
below:
Sunday 4 March 2001 22:56 UTC to Monday 5 March 2001 01:29 UTC
Monday 5 March 2001 23:54 UTC to Tuesday 6 March 2001 02:28 UTC
Friday 9 March 2001 02:46 UTC to Friday 9 March 2001 05:19 UTC
Saturday 10 March 2001 03:47 UTC to Saturday 10 March 2001 06:04 UTC
They will be operating on 1296.001. Please keep off this frequency to
avoid interference with their signal.
EME transmissions between 1296.005 and 1296.010 are encouraged!
Your help will be appreciated. Please pass the word on. Sorry for the
late notice, but I just received this information.
73, Al - K2UYH
On numerous occasions over the years, the Arecibo radio observatory in
Puerto Rico has been QRV on EME, giving some of our smaller stations a
BIG
SIGNAL off the Moon. Now, we have an interesting opportunity to turn
the
tables, and give the folks at Arecibo something interesting to listen
to.
The SETI Institute's Project Phoenix targeted search for
extraterrestrial
signals operates intermittently at Arecibo (in receive mode only). They
have long used a weak microwave beacon on the Pioneer 10 spacecraft to
calibrate their receiving systems. But Pioneer 10 is now beyond the
farthest fringes of the solar system, and its signal has not been heard
for
some time. Thus, for next month's Project Phoenix observing run, 1296
MHz
EME stations have a chance to provide test signals for Arecibo.
The SETI League is hoping to have its EME beacon transmitter
(see
<http://www.setileague.org/press/pres0005.htm>) operating at 1296.000
MHz
during Moon transits of Arecibo, signing the club callsign W2ETI. Other
amateur stations are encouraged to transmit test signals in the 1296.005
to
1296.010 MHz range, during those periods when the Moon is visible to
that
305-meter dish. Here are the dates and times Arecibo will have a good
EME
window:
Sunday 4 March 2001 22:56 UTC to Monday 5 March 2001 01:29 UTC
Monday 5 March 2001 23:54 UTC to Tuesday 6 March 2001 02:28 UTC
Friday 9 March 2001 02:46 UTC to Friday 9 March 2001 05:19 UTC
Saturday 10 March 2001 03:47 UTC to Saturday 10 March 2001 06:04
UTC
Note that these are AOS and LOS times for Arecibo, at the limits of its
tracking range. It is uncertain at what exact time Project Phoenix will
be
listening for our signals, so a good illumination of the Moon during
these
periods will be appreciated. Remember that Arecibo will be in SWL mode
only for these tests, and will NOT be transmitting. However, this
should
be a good opportunity for the EME community to make some random 1296
QSOs,
while providing helpful test signals to the scientific community.
