We seem to be in the dog days of summer before
summer has really begun. The end of May SW did not produce
particularly great conditions, but the main complaint was
activity. The truth is that we have had an exciting winter
and spring with lots of contests, now we need an exciting
summer with summertime dxpeditions to attract the troops back
to the bands. Some of these dxpeditions are happening, but
there has been little in the way of fanfare to make their
presence known. For example TK/DC3VW/p is on the Island of
Corsica with 8 vertically stacked yagis and 200 w. Enough to
easily work DL9NDD. Another possibility according to K5JL is
activity from TI2NA in Costa Rico. Letís get the word out and
those summertime dxpeditions rolling!
The 8th 432 MHz and Above EME Conference is little
more than a month away. Information and up-dates can be found

The results 1st EME SSB Contest have not changed
much since the Feb NL. OE9XXI is still in 1st place with
48x13 for 624 points. (48 is 2 x the number of SSB QSOs plus
1 x the CW/SSB QSOs). Unfortunately there are a number of
stations which should have scorer high but never submitted
their logs. OH2AXH and K2DH have to be among these. Because
of this I (K2UYH) am in 2nd place with 35x9 for 315 points
and W2UHI 24x10 for 240 in 3rd place followed by G3LTF with
25x7 for 175. Certificates will be awarded at the Paris
Conference. The 2nd EME SSB Contest is planned for the Feb SW
of '99. Is there any interest in extending the contest from
1296 to 70 cm or 13 cm?
Frank was active on 1296 for the 2nd May SW. He worked
the following on random:
TM8EME, G3LQR and OZ6OL. All QSOs
were initials. For skeds contact Frank at e-mail:
Guenter is now QRV on 23 cm and was active during the
2nd May SW. His rig at present is a 5 m dish with 70 w at the
feed. Guenter plans to extended his dish to 6 m later.
Guenter's e-mail address is:
Csaba's (HA5BGL) group was active on 1296 on the
weekend after the SW and are available for skeds. They are
located in JN97mn and equipment with a 3.6 m dish with linear
horizontal pol, 100 w at the feed and a FHX35 preamp. They
follow the Moon by a telescope, so they can only operate at
night when it is dark. Csaba is interested in skeds with
"bigger" stations and can be reached by e-mail at:
Andrea (JN53fu) writes -- I found excellent 432
conditions in the presked weekend (perigee), but very low
activity. Anyway I was very happy because I worked 2 more 4
yagis stations with my 2 x 28 el 9 wl yagis and 800 w. It is
interesting what QRP can do if one finds the right
polarization shift HI! I worked on 23 May
K5JL (539/559) UFB
for initial #26, W7QX (O/O) #27 - my 2nd 4 yagis
heard was K7XD (M/-) and nil KB3PD due to local QRM but he
copied me, on 24 May W7CNK (O/O)
#28 - my 3rd 4 yagi QSO, and
31 May OE5EYM (539/O)
on random and nil F1AHN. My homepage is:
Steve has been extremely busy with little time for EME
or ham radio in general. He spent quite a bit of time this
spring looking for land to build a new house. If he were to
put up his 28' Kennedy dish at his present location he would
have a limited window due to tree blockage. Unfortunately,
the only property that he was able to find that met all the
requirements, dish window, good tropo location, buildable lot
and plenty of privacy was quite a bit farther out in the
country than where he presently lives and not where either he
or his wife want to live. At his present location there are
only 5 houses within a half mile (.8 Km) radius. Most of the
surrounding land is part of a water reservoir and open space
land trust, very good for ham radio. He is now planning on
expanding and remodeling his present house. The job of
developing the plans and finding a contractor has more
recently occupied his time. The plans include building a new
larger shack on the 1st floor to replace his somewhat small
shack over the garage. If he proceeds ahead with the plans
his present shack will have to be dismantled before the
renovations start. In addition all the feedlines will have
to be dug up putting him off the air for several months. He
and his wife are attempting to make a decision as to whether
the results of the remodel will be worth the pain of doing
it. In addition to the house work he has been very busy at
work and with Lunar-Link Systems. Steve was up at the
Rochester, NY hamfest and chewed the fat with the 70 cm and
up EMEers who were there. Stations worked past months were on
8 Mar I5TDJ and WB0GGM, on 4 Apr
K5WXN, DF3RU and DL4KG, on
30 Apr W7CNK, KA0RYT and JA5OVU,
exchanged grid squares with
KA0RYT and JA5OVU for the 432 ARRL Spring Sprint Contest, on
1 May VK4KAZ (M/O) #533, DL9KR, and W7CNK, on 2 May JA9BOH,
K7XD, N2IQU, JA3SGR, JA3IAF, JH4JLV and JJ1NNJ, on 31 May
K5JL, W7CNK and JA5OVU, and on 7 June W7CNK.
rotor (an HDR- 300) again has output shaft keyway problems
and now has at least 45 degs of backlash in it. He is just
about giving up on the HDR- 300 as he feels the only way to
fix the problems would be to go to a spline output shaft and
gear, but he has been able to find suitable parts. Steve is
considering using a prop pitch motor for polarity rotation,
but it would require quite a bit of modification to his
mount, plus they are slow and noisy. He looked at the M^2
worm drive rotor, but it is too high to fit into his mount.
He is considering trying a Yaesu G-2800SDX rotor. On paper
the braking torque looks very impressive, but the motor
turning torque looks a bit marginal. He wonders if anyone has
any experience with the G-2800SDX rotor? Steve's 70 cm EME
totals are: #532 initials, 49 states and 75 DXCC. Svetlana is
just now shipping their long awaited version of the 3CX800A7
triode. He has been testing a pair of Svetlana tubes in an
LA-70B, 70 cm amplifier. Initial tests look encouraging, the
Svetlana tubes are very stable in terms of power output,
operating just like a HF amplifier. They bias slightly
different than the Eimac tubes, however and require more
drive power. Lunar-Link Systems is now stocking both Eimac
3CPX800A7 pulse rated tubes and Svetlana 3CX800A7/3CPX800A7
Harry is using a 3.2 m dish and 200 w on 1296 and
writes -- I now have a max of 65 degs of elevation available
so I can now take stateside skeds on 1296. I am good until I
reach an azimuth of 205 deg where I am blocked by trees. One
short window remains for me from 255 to 265 deg for above 35
degs of elevation. During the SW I worked K4QI
(O), nil EA3UM, PA3CSG (439), nil I6QGA, nil F2TU, nil
GW3XYW, nil N2IQU, N6BQ (O) and K2UYH (549).
worked every station heard, had 5 no shows on skeds and QSO'd
3 on random. My initial count is now 25.
Russ writes -- I was on 1296 over the activity weekend
for a couple of short periods. Conditions seemed fairly good.
I worked on 30 May W2UHI, N6BQ, DD1XF, OZ6OL for an initial
(#), DF4PV #, K3HZO #, DF3RU, OK1KIR, OZ4MM and PY5ZBU #, and
on 31 May W2UHI, HB9BBD (very loud) and K2UYH.
Around 2020 on
30 May, I heard someone calling several times. They were very
weak and sending very slow. With the slow CW, the libration
chops a weak signal up to the point you really cannot copy
anything. I missed the TM8EME tests last month because of
very high winds the whole weekend. [Russ can be reached on e-
mail at Russ, K4QI ]
Roger is presently not QRV due to the passing of his
aunt. He is not sure when he can get back on. He is involved
with settling her affairs. She was a teacher from 1944 to
1974 in Anchorage and amassed a lot of things, many of which
are turning out to be historical in nature. Roger notes --
I'm sorry that this is happening but will let you folks know
when I can get back on. Please let the gang know that I do
not want any schedules as of yet. I don't want hurt feelings
when I donít show up or don't answer my e-mail right away. I
have had almost 50 messages alone. [You have the sympathy of
the EME gang. We understand the situation and will be around
when you are ready for the Moon again.]
Joe is QRV on 70 cm with 4 yagis and now has an LA-70
online running 1500 w. He worked DL9KR (569)
on 2 May at
2200, but heard nil from DL9NDD on 3 May. You can reach Joe
Hoppy's 23 cm activity report for May follows -- I
QSO'd on 11 May W2UHI, on 23 May DJ9YW and OZ6OL for initial
#122, on 24 May W2UHI, DL6YDH, DH0OAH #123 and DJ9YW, on 30
May W2UHI, KD4LT and K4QI, and on 31 May JA6CZD, W2UHI,
W7GBI, HB9BBD, G3LTF, K2UYH, OE9ERC and K3HZO #124
. I had a
near miss with K9BCT
on schedule. No contact since I never
copied Randy's Rs. Also I didn't hear anything from 9H1ES on
schedule. I increased anode voltage on the TH-327 PA to 3.0
kV dc under load and ran 1.5 kW output for several hours
straight with no big bangs! I ran approx 1.3 kW during the
entire weekend with very stable operation. The new method of
disabling HV and Esg during RX seems to be working. A new
feed, VE4MA with built-in polarizer section and 7/16 con-
nector on TX port is almost ready to be installed.
Shawn is now QRV on 432 from DM09 (Reno, NV). He is be-
lieved to be running close to the legal limit into 4 x 25 el
FO yagis. Ron, KA0RYT reports working Shawn (M/O) and says he
will be temporarily down to move his array to a rarer grid
for the ARRL June contest - portable style.
Zdenek sends the following report on his 1296
activity during the 30/31 May SW -- I worked OZ4MM (O/M),
OK1KIR (O/O) and HB9BBD (559/539) - very strong signal with
peaks to 579. Heard were ON5RR, OZ6OL, K4QI, DF3RU, N6BQ,
LU6DW, OE9XXI and OH2DG. I used 150 w. I have a new
preamplifier made by OK1CA with 0.5 dB NF. Receiving side is
thereby very much better. In next 2 windows, I am sorry to
say, I will not be active. I will work on completing a higher
power amplifier with a TH338 for the next time I am able to
Marc, just back from the Italian EME convention,
writes -- We intended to work all our skeds, but had
problems. When we came on we heard HB9BBD with an outstanding
signal. His 10 m dish is doing a great job! It was easier to
work Dominique than ever before. Then I got on the sked freq,
but during echo testing the EHT of the driver blew. I tried a
backup one, but the only thing it wanted to do was oscillate.
It even killed the OZ9CR amplifier... Finally I used my 1st
amplifier (2x2C39). With reduced drive and EHT I could only
make about 60 w. I could hear my own echoes, but nil on all
skeds. I heard very weakly PY5ZBU and worked some big guns.
We are busy making repairs and hope to be active in June.
Stig was QRV on 1296 for the SW -- I worked some
stations, but didn't find activity too good. Conditions like
activity seemed down. QSO'd on Saturday were HB9BBD (57/56)
on SSB, DF4PV (529/449) for initial #140, JA6CZD (559/569),
DF3RU (549/569), OK1DFC (M/O) - much weaker than normal,
OZ6OL (549/559), IK2RTI (439/549) #141, LU4DHD (O/549) #142
DXCC 36 and JR9NWC (M/O) #143.
Back in beginning of May I
worked TM8EME (59/58) on SSB. Concerning my e-mail address,
there was an error in last NL! The address should be:
Hans writes -- I was QRV for the TM8EME tests and re-
ceived good signals from them but did not succeed in making a
contact. Several lessons were learned. Misalignment of the
dish was the 1st and biggest mistake. Measuring the Sun noise
helped me discover the alignment problem. 2nd was the NF of
my preamp. Measuring only 8 dB of Sun noise indicated that
much improvement could be realized in building a new preamp.
I am building a DJ9BV design with a HEMT to replace the old
MGF1302 preamp. The biggest surprise was that during the
TM8EME activity I heard several other stations on the same
frequency as TM8EME. This gave me my last lesson that my CW
knowledge must be improved. Activity from my side will be to
build a dish and perhaps do some tests with my 2.5 m dish.
The spark is glowing and something will result.
Jerry heard nil on 23 May from W7CNK, HP3XUG and
K5JL. He notes that he will be away in SV9 from 29 May to 2
June for a 2m EME and MS dxpeditions. He will be again QRV on
70 cm on the weekend of 20-21 June. On the weekend of 27/28
June he will be away from Athens on a business trip.
Jeremy in ID (DN14wv) is just about set for EME
operation on 70 cm with 8 x 432cp42ug modified cross yagis
and 800 w from a pair of 4CX250Rs. Jeremy has stereo RX via
FT1000mps, dual stage preamps and separate feeders. He notes
that 222 and 13 cm EME are in the works, but that 23 cm is on
the back burner. He expects to be QRV in June pending some
tree removal. His address is (Jeremy Alexander, PO Box 1818
McCall, ID 83638), tel 208-634- 4466 and e-mail:
[PA problems have delay Jeremy,
but he expects to be QRV very soon.]
I was only able to be on one day during the SW and
chose to try 1296 as I was on 432 last month. Conditions did
not seem very good, but I did QSO on 31 May at 1921
(57/54) on SSB with an immense signal, 1944 OZ6OZ (549/559)
for initial #153, 0200 K4QI (559/559), 2021 K3HZO (549/O)
#154, 2032 N6NB (559/549), 2043 G3LTF (559/549) and 2100
OE9ERC (56/56) on SSB. I was again on 1296 the post SW and
worked on sked on 6 June at 2330 HA5SHF (O/O)
for #155 and
DXCC 37. Signals were up and down due to tree blockage at the
low declination. I used circular pol even though HA5SHF was
linear as I did not read his e-mail carefully. Afterwards, at
0010 W2UHI was QSO'd (55/44) on SSB, but signals were erratic
due to the tree problems. I also ran several skeds with
VK4KAZ on 432, but only copied pieces of calls. My window to
the west has just about disappeared! I may have to wait until
the leaves come off the trees before I can work him.
EA3UM has been away on business travel. Magi was unable to
make his skeds with SV1BTR and WB0GGM and sends his apology.
WD5AGO is looking for an Australian station on 23 cm.
K2DH plans to try with AF1T on 903 and then he will put the
23 cm feed in for the June SW and will migrate to 13 cm.
N7EIJ has 8 yagis from N7ART and hopes to be QRV on 70 cm by
end of the summer. He still needs a PA.
W4HHK had a visit from W5LUA and W5ZN on their way to Dayton.
9H1PA has a 2 m solid dish with a .4 f/d. He plans EME on
DL9KR, worked VK4KAZ for initial #691 and KU3T #692. Jan is
looking for a sked with WA6YDI. He reports TK/DC3VW/P has
worked DL9NDD quite easily with 8 vertically stacked yagis
and 200 w. Jan is also looking for info on W6ZL.
K6IBY needs a couple RCA 4634 tetrodes and then will be QRV
on 432 EME. Joe reports that Fresno State college is putting
together multi band EME station with a 6 m beam with a 70
foot boom, 4 x crossed yagis (K6MYC) for 2 m, 4 x M2 24' long
on 220 and multi yagis on 70 cm. Hams involved in this
project include WA6YDI and K6MYC.
ON4KNG completed with SV1BTR.
DH0MBH has 6 yagis on 70 cm.
W2UHI worked OZ6OL for a new one on 1296 in May.
VE1ALQ's new dish will be in the air in about 2 weeks. The
dish is a 12' TVRO for 5.7 GHz and above.
KA0RYT worked GW3XYW for a new one and also W7CNK, but did
not complete with OE3JPC.
HB9BBD's new dish is working very well. Dom has worked 60 QSO
with it thus far.
W0RAP's dish is up but not operational yet. Bob will be
working on the dish actuators now that the WX is better.
W4OP heard WA9FWD and K3HZO on 23 cm. He has 700 w out and
will be look for them on random.
HP3XUG did not hear SV1BTR. Louie did heard W7CNK twice, but
did not complete.
K7XD did not complete with KB3PD and IK5QLO.
PA3CSG has 15 dB of Sun noise with his 3 m dish on 10 GHz and
is working on the TX side.
9H1ES has not sent out QSL cards yet. He will try to send the
QSLs in next 2 weeks. He had a very fine QSO with HB9BBD on
10 May. He plans to build a bigger dish.
W5ZN is QRV on 70 cm and 6 cm and is looking for skeds. He
will be moving to 23 cm soon. He still needs VE4MA on 902.
NU7Z worked AF1T and WA8WZG on 903.
AF1T has worked on 903 WA8WZG, NU7Z and K2DH and tried with
VE4MA, but heard nil.
N2HLT has 4 x RIW yagis and 600 w, but is planning to take
them down and put up 8 x K1FO yagis.
WA8WZG has worked AF1T and NU7Z on 902 and is moving to 5760.
W2UHI missed his DH0OAH sked, but did work N6BQ and DF4PV for
a new one on 1296. Frank had some minor problems with dish
control, but now has resolved them.
K5JL has finally worked SV1BTR. Jay had a tornado pass a
couple of miles to the north. Jay reports that TI2NA, Eric,
has 4 yagis and needs encouragement to get back on 70 cm.
W7FN is recovering from an operation and not QRV at the
K9BCT had a sked with N6BQ. He had easy copy on his end, but
had to leave to catch a plane. His diagonal horn is now
working very well.
WB0TEM plans to be active again on EME. It will take Mark a
few hours to get his dish back in service, but work has
begun. He expects to be QRV by autumn.
VE4MA is thinking of firing up on 24 GHz pretty soon.
LX1DB worked OE9ERC on 5.7 GHz.
W6/SM0PYP Paul has a new address (P. Chominski, 17433 Gi-
braltar Court, San Diego, CA 92128), tel/fax: 619-676-0381 and
KU3T has for sale a 3CX800A7 Power Amplifier based on the

This month we have a modification for the
and similar 6 tube ring amps from G3LTF. Peter writes -- for
sometime I have struggled with various input circuit
arrangements for my home brew 6 tube 3CX100A5 amp. I used
loops and direct ground taps from the sidewall, but I
believed these all upset the symmetry of the cavity
operation. I recently changed to a direct tap on the central
tuning slug. This seems to do the job with much better
balance of currents in the tubes - see the diagram at the end
of this NL. The dimensions are approximate. You may have to
Also in this NL is the list of stations on microwave EME
prepared by NU7Z.
JF1EFA with 4 x 26el K1FO Array
JF1EPA's Solid State 432 HPA
8 x 2C33102 for 600 W Output at 432 MHz.
This month there was only a 3 week turn around between
SWs. Unfortunately we have to leave for a business trip on
the weekend we would normally prepare the NL. Thus the NL is
a week later than normal. I am sorry for this delay, but
there was nothing I could do. The rest of the summer does not
look much better. We will be away on another trip at the end
of June and the will be gone again for several weeks for the
Recordings of the TM8EME QSOs have been uploaded to the WEB
by F5MZN. Samples of all QSOs are available. The records are
saved as WAV format, 8 KHz, 8 bits, mono. If you want to
hear your signal or one of the others, connect to:
TM8EME Sound clips
and then after
entering one directory, click on the file you want to listen.
It can take some time before being able to listen a
particular record. It depends of the file length and of the
date rate available to you.
Thanks for the technical material and reports. Please keep
the information coming. . I should be QRV in June SW and will
be looking for you off the Moon.
