Net Notes-5 OCT
We had quite a few checkins on 20 and a good session. Propagation to
EU was minimal.
W2UHI- Frank worked SM2CEW on 23 CM. Working with TS-2000 as 144 IF
due to lightning strike...Rx is noisier.
K5JL- Jay worked SM2CEW and G4CCH on 23 CM. Sigs are good.VK3UM ison way home
to Aussie wearing his new Black Hat! Doug will be qrv on 23CMsoon.
K2DH/M- Dave is on way home from vacation. He has sold house and ismoving to
new QTH. Details soon. Wants to know if anyone else is goingto Microwave update
W5UN- Dave was mobile in Ia on way home.
N4PU- Jim has completed new feed mount. It works f/b. He has also fixedthe Az
gear ratio. Now runs at slow speed. awaiting the arrival of repairedtracking
system. Looking for 1296 directional coupler.
W9IIX-Doug is making good progress on 23cm system. Now has split tx/rxlines on
ft-736. Preamp is repaired and on way from WD5AGO (thanks Tommy!)Protect relay
is also on way.
WD5AGO- Congrats to Tommy for receiving the Teacher of the year awardfrom the ARRL.
Tommy admitted that the Pix of him that was in qst was 4years old!! He will be
qrv for the contest on 23cm.
W5LUA- Al picked up 2 2.6 meter dishes in Minn last week. Will usethem for 24
and 47 ghz projects. Also congrats to Al and Barry on greatEME artical in QST.
The EME history part was especially appropriate.
W7CNK-Lucky checked in, no traffic
W8HAP- (ne K1RQG) having fun at Hamfest
VE4MA-Barry has snow on ground in Manitoba. Will slow down sun noisetests on new
offset dish on 24 and47 ghz. Working on 24 ghz converter,cleaning out the weather
Sm2CEW-Peter qso'd W2UHI, K5JL and others on 23CM. Good sigs. Has skedson 70 CM.
Station improvements with new amp and much improved trackingsystem have kept him
very busy this summer.
K7XQ- Jeff was qrv on 23 CM. nothing heard. He was on too late forthe activity.
Has issues with dish window. Not sure of new VE4MA feed.Is using Icom 1271 and
single stage preamp. Sounds like his gain is low.He also needs to find focus on
dish. J and I will contact and try to helpout.
K0YW- QRV on 23 Cm with driver power only took final apart. Found 2problems...
fixable but awaiting new parts. May not make the contest withamp.

DJ5MN on 10GHz-EME in ARRL EME contest 2002
After several years being active on 2m-, 70cm- and 23cm-EME I now try to
make the next step: EME on 3cm.
When I started this project 2 years ago I was an absolute greenhorn
to 10 GHz knowing nothing. Now it looks like I have all equipment running
OK on 3cm and I like to try 3cm-EME in the ARRL EME contest from my new
Details of my small 3cm-station :
more than 100 watt at feed (vertical polarization) Is this OK??
1.5 m parabolic dish (f/D 0.407, gain 42.4 dBi), manually turned in azimuth
and elevation (visible moon)
(dish has limited window)
preamp less than 0.6 dB NF
RX: I believe in my ears so no computer analysing
Due to bad weather I still have not echo-tested.
Now I am looking for those 10GHz-EME-freaks who are interested in trying with me
in the contest and like to arrange a sked.
What about you?
For skeds please drop me an email.
I am also interested in the kind of equipment you are using for
10GHz-EME and any kind of hints for 3cm-EME!
Please always send emails to both of my addresses:
firstname.lastname@example.org and email@example.com
GOOD LUCK IN THE CONTEST TO YOU

Subj: report from WA6PY
Date: 9/30/02 2:40:01 PM Eastern Daylight Time
From: firstname.lastname@example.org (Paul Chominski)
To: email@example.com, firstname.lastname@example.org
Hi Al and Joe,
WA6PY: I switched feed to 13 cm and on Sept 28 QSO'd in skeds OK1CA and HB9SV, NIL
from G3LTF, next day QSOd G3LTF. I have some problems with my 13 cm PA with YD1381,
power suddenly jumps down by 3 dB and I have to retune cavity. I could not perform
any deeper test during skeds. On 2320 I have increased noise floor versus 2304.
Then I switched on 2424 receiver and found that the band is covered by very strong
wide spread modulated signals. It looks lie Bluetooth or 802.11b, but at the moment
I can not borrow spectrum analyzer in order to check what it is. I am using my 15
years old LNA with very high gain close to 60 dB in order to overcome cable loss
and high NF of the converters and loss in splitters and band pass filters.
Consequently Input IP3 of my RX system is very low. 15 years ago it was no need for
high IM performance, but it looks like now it is a must on 13 cm.
I am preparing for multiband operation in the contest. In October I will operate
on 144, 432 and 23 cm and in November I am planning to be on 144, 432, 23cm and 13cm.
On 144 I will use two yagis pointed on horizons toward Europe and on Moon set JA and
VK. The window will be short. On 432 I will use dual dipole / dual polarization feed
and the Moon window will be longer, but I will be able to work only few big guns.
I will move the position of the feed, so basically I can cove entire Moon window.

==Subj: [Moon-Net] 432 EME
Date: 9/30/02 8:00:40 PM Eastern Daylight Time
From: email@example.com (Joel Black)
I have recently relocated and am interested in moving from satellites to
EME - specifically, 432 EME; eventually graduating to 1296 EME. I currently
have the Yaesu FT-847 and G-5400B rotor and controller. At this time, I
have no amp or preamp and want to just experiment with JT44. Also, I'm
planning on building the K1FO 432 antennas described in the ARRL Antenna
Handbook. These are my plans...
Sometime in the past, I found a website from a ham located in England. It
had a very descriptive webpage regarding his setup. He had a 4-yagi (I
think) array setup in his garden. He also mentioned something about being
apprehensive about starting EME due to his lack of CW experience. I can no
longer find this website.
If anyone can offer suggestions for my setup and/or a url for the previously
mentioned website, I'd certainly appreciate it.
Tnx es 73,
Joel Black, W4JBB

Good morning Joe....Have been working on two things on the Dish. The first is the
failure of a Pillow Block on the pulley and belt system. The other is some
reinforceing welding on the dish mount, which should be completed in a few days.
The tracking system is working fb and am getting good echo's.
Thank you again for the good information you are sending. Especially the Contest
info coming up soon. You have covered that very well. 73 Jack N7AM

I've changed my internet service provider, so would you change your mailing
I've completed my second EME array (4 x 21) for 432 mHz and have some new
electronics purchased from Dave (K2DH). My sun noise measurements seem
acceptable, but my moon noise test failed. I don't know if the moon can be
detected on 432, though. I'll be carefully monitoring during the upcoming

Subj: [Moon-Net] FS: 23cm cavity PA
Date: 10/12/02 1:03:09 AM Eastern Daylight Time
From: Thomas.Hoeppe@asamnet.de (Thomas Hoeppe)
To: email@example.com (moon-net)
I´m selling a 23cm cavity for 2x 2C39 tubes. The unit is a complete
HF-module made by EME Karl Müller (The same the HF400 relais comes from...)
With 6W input you get 150W out, I have the input/output diagramm of the
manufacturer if you are interested. 10W input is possible. The unit has a
very effective cooling of the whole tube, running a silent EBM radial blower
into a air leading system. As it is a cavity, the anode coolers are "cold"
(no RF) and you can change to watercooling if you need more power. It comes
complete with a new matched pair of 2C39BA from siemens inside, 2x original
bias-cirquit board (1 spare). All silver-plated and in excellent condition.
Further I have the original power supply from EME Müller, including the
transformer with 3 taps on the HV-secondary, heating, small-voltages,
ceramic-switch to change the anode voltage, DC-cirquit-board with current
Ask for 300 Euros for the HF unit, 150 Euros for the power-supply. Selling
all together is prefered, so contact for special conditions.
I´m also looking for an Icom IC 475E/H for the DL0AO 70cm EME station.....
