is in construction to show how we did
it. The station includes a dual-dipole with 500 W at the
feed from a TH-F6007 coaxial cavity PA with DXl1503 LNA in
DJ9BV design. We measure 4.5 dB CS/G noise. During the 1st
part of the Eur contest we worked VK3UM (559/559), JA6AHB
(569/569), SM2CEW (549/549), DJ5NV (559/559), UA3PTW (O/O),

and WA4NJP (449/559) for a total score of 47x31 = 145,700
points. Heard were 7M2PDT, DL/OM9AME/P but missed. I'm
working on the 23 cm equipment and hope to be QRV for the
2nd part of the contest. Hopefully there will be not too
much disruption from F6CGJ, who is separated by only 5 Km.
I'll be in Prague and hope to meet all of you.
Graham built a 432 feed (a pair of dipoles) for his
4 m dish and is hearing the bigger stations. He plans to try
calling on random bigger stations as DK9KR and DJ5NV. Graham
was on 23 cm during the SW and worked SM2CEW, G4CCH, W5LUA
Simon drops a line on his activity --
Progress has been slow on my new PA for 23 cm using a GS35b.
Others seem to report only 500 W out, but I will be happy at
that power. My new PA for 432 MHz using an RCA 4661 runs
nicely at full power. I now need to improve my 432 antenna.
At present sun noise is only 12 dB. I removed the open wire
from each bay of 4 yagis and replaced it with LDF4-50 to
check both bays and adjust SWR. I have 9% reflected at
present. I just need some warmer WX and time. The 4.2 m dish
is still ok after some big storms during winter. Operating
has been slow, but I did get on 13 cm for the DUBUS contest.
I worked 7 stations and heard 2 others. QSO'd were OE9XXI,
SM3AKW, F2TU, OH2AXH, OK1CA, G3LTF and OK1KIR. The RX was
bit deaf on Saturday, but the sun noise was close to 16 dB
on the Sunday. My power is only 80 W out in shack from a
YD1050. Some more would help. I'm looking for a GS34. My 9
cm EME project is still on hold, but I will try harder this
year. I will be on 23 cm for the DUBUS contest.
Peter writes -- At last we got some decent WX and I
could operate EME again! I went on 1296 on 21st March to try
out my system as I have been making a number of changes, new
relay, higher edge illumination, -12 dB, realignment of
polar axis and auto follower system. Echoes were good,
especially on SSB and I worked OZ6OL and G4CCH. I was on
for the contest and on 432 worked on 23 March SM2CEW, VK3UM,
VK4AFL, JA6AHB, DL1YMK, F6KHM and WA6PY for initial #355,
and on 24 March PA0AVS, #356, F2TU, UA3PTW, UT3LL, DK3WG,
YO2IS, SM3AKW, K0RZ, WA4NJP, K1FO, RA3LE, DJ3FI and G4YTL
#357. CWNR were K9SLQ, WB0GGM and SK0CC - got report but no
completion due to QRM. On 13 cm, I worked (x means crossband
QSO) on 23 March OZ4MM x, OH2AXH x, SM3AKW, F2TU x, OE9XXI,
OE9ERC x, and on 24 March G3LQR and OK1KIR. CWNR were OK1UWA
and JA4BLC x. Nothing was heard from NA. I measured sun
noise on all 3 bands with a 2.8 GHz sun flux at 175 with the
following results: 432 = 15 dB, 1296 = 21.3 dB and 2320 = 17
dB. This is with a 6 m dish. I have been doing some
interesting work on dish illumination measurement, which I
will report later. I missed about 4-5 hours of operating on
Saturday when a motor relay burnt out. My apologies to K9SLQ
and W4ZRZ for missing our skeds.
Dave in March spent some time on his array and all
damage has now been repaired -- I was able to get on 432 for
the DUBUS/REF Contest and worked HB9Q, K1FO, OH2DG, OE5EYM,
SM2CEW, G4YTL, K2UYH, K0RZ, DL9KR, SM3AKW, and F6KHM. All
were worked with only 350 W out of my EMFD PA. The following
were CWNR: DJ5NV (2 hours), SK0CC, PA0AVS, S52CW, DL8OBU,
ON5OF, AA3GW, DJ3FI, K5WXN and F2TU. Head were G4ALH,
UA3PTW, EA3DXU and WA4NJP. I hope to get the P/S for the new
PA finished soon, QRL permitting.
Mark's recent activity has
been a little intermittent -- I was QRV for the SSB Contest,
but true to form the PA was giving me trouble. A water leak
prevented me from joining in on the Saturday. Many good
signals were heard. On Sunday I managed to work K5JL and
OE9ERC with reduced power output. ZS6AXT got away. I
arranged a sked with Ivo for the following weekend (2
March), but heard nothing. During the week whilst I was
away, a storm had bent the support for the actuator arm, and
I was about 8 degs off - just enough to stop me from finding
Ivo. The weekend of 23/24 March was again disappointing. On
Saturday there was little activity heard, but I did work
G4CCH on random. On Sunday the PA sprang another leak and
gave up again. I heard HB9BBD (549) at times and (52) on
SSB, IK2MMB (529), K5JL and a few weaker stations that I did
not have time to identify. I was to busy trying to dry out
the PA valves. I am getting a screw on heat exchanger put
together. De-ionized water seems to eat through the solder.
I may even just use good old Scottish tap water. The leakage
current is not too bad - Hi. I have made some improvements
to the dish positioners, and the materials will take a lot
more to bend them! Work is progressing slowly on a TH328
amplifier. I am also working on a VE4MA feed with polarizing
screws. I measured a large increase in sun noise - from 8.6
dB to over 11 dB when I bypassed the hybrid. It has to go!
The preamp is improved and now has a 0.35 dB NF thanks to
G3WDG. I can be QRV from now through the Easter period, any
skeds are welcomed.
Kouiche's March contest report
-- I worked on 70 cm on 23 March at 0430 WB0GGM (O/M) in V
on sked for initial #75, 0622 JA6AHB (O/M) V, 0641 VK3UM
(559/339) V, 0705 KL6M (449/549) V and 1301 RA3LE (O/O) -
20/+40 deg pol, and on 24 March at 1238 UA3PTW (559/549) V,
1347 F2TU (559/449) V #76, 1421 DL9KR (579/559) V and 1429
SM2CEW (559/539) V for a total of 9x8. Also heard were K1FO,
W5WXN, K9SLQ, VE6TA, DL1YMK, DJ5NV, F6KHM, OK1KIR, UT3LL,
SM3AKW, VK4AFL, 7M2PDT, JS3SIM, JH4JLV and JH0WJF. Condx
were good during the night. Many Eur stations were active. I
was very happy to complete QSOs with RA3LE on random and
WB0GGM on sked. My equipment is 16 x 13 el (2.7 wl) yagis LR
with a 250 W solid state PA (3x MRF176GU) and FHX35LG LNA.
Yoahiro, JA4BLC reports that JH0YSI cannot be QRV on
432 because their yagis were badly damaged. They have no
plans to repair. JH0YSI has a single 2C39 PA with an output
of 100 W on 23 cm. They hope to get a better tube and more
power soon. As their dish is manually controlled, they are
not interested in sked requests before they get their
Bruce had multiple equipment
problems in March -- Murphy visited my shack. After fighting
another dead elevation board, I had low drive to the rig a
bad attenuator, power was down to 200-250 W before back up,
and the PTT line to the foot switch quit too. Despite these
problems, I had good results on 23 cm. I worked W4OP
(569/549) and (55/55) on SSB, W2UHI (559/569), WA1JOF
(519/539), K5JL (559/589) and W7BBM (559/559) and (55/55) on
SSB. The dish now tracks fine. I'll have the rig back to
full goo soon. I was hearing my own echoes (579)
consistently even with low power. I ran some real low power
checks. With only 2 watts out, my echoes were Q5 on CW. Jay
can do the same with 1 W, but has ½ My TX feedline loss.
Tony will have trailer mounted 4
m dish on 23 cm in a short time – I am waiting for VE1ALQ
amp and feed. My TX power should be around 200 W from a two
2C39 PA. This is the dish I was using to work W4HHK on 2304.
Later in year I will be back on 2304 with about 300 to 350 W
on 13 cm. I also plan to be back on 5760 with 70 W, if
activity is there. I have a 16' Scientific Atlanta dish that
I would like to put on, but that will not be a while. By the
way, I have moved from Grove, OK (EM26 to EM37), near
Springfield, Mo. My plans are to pull the dish to AR, KY,
etc to help with states.
Dan found lots of activity on 70 cm during the Eur
contest, but had to shut down part of the time due to high
winds. He worked quite a few stations including initials
with F2TU and VE6NA. DL1YMK was called, but on his reply at
least 3 strong stations also replied causing much QRM! Dan
asks about where to send DUBUS/REF contest logs. [Send them
to Patrick Magnin, F6HYE Marcorens, F-74140 BALLAISON
France, or e-mail logs in ASCII format to f6hye@ref-
Wayne in March worked SK0CC with good signals, but
heard nil from 7M2PDT. K5AZU, K4QI and VK3UM were also
worked for new ones. He has taken his antennas down to be
upgraded, but expect to have them back up for the April SW.
Mike is back from a vacation in Hawaii -- Thanks to
WL7BQM, Mike, in Sterling, Alaska, I plan to be QRV on 1296
in time for the DUBUS Contest. He is loaning me a VE4MA
feed, tuned by Darrel and a 160 W brick, which we plan to
mount at the feed. My preamp is a 0.4 dB NF DEMI. I have to
get the whole thing operational during a 3 day weekend next
week. I still don't have my improvements finished to my
position indicator. I will be trying to get it operational
also, but I plan to operate even if I don't finish it. I
will just have to spend a lot more time tweaking the dish
without it. WL7BQM is working on a 23 cm system of his own
with a 16' dish.
Franta's report from March -- I was
QRV on 13 cm on 23 March and QSO'd F2TU (559/559), OE9XXI
(559/559), OE9ERC (569/559), F1ANH (449/439) for initial
#16, OH2AXH (559/539), SM3AKW (449/439) - all on 2304 MHz
and G3LQR (O/O) #17 on 2320 MHz. It was very cold with snow,
and activity only from EU was possible. There were 3
stations on 13 cm from OK (OK1KIR, OK1UWA and OK1CA),
together with the activity from OE (OE9XXI and OE9ERC) it
was possible to fulfill the conditions for the Johannes
Kepler EME Award in one evening on 13 cm!
Yonda, OK1DAI reports on
the 1st part of Eur Contest by his club – We worked the
following stations on 432 MHz, on 23 March at 1244 KL6M

EL99), 0033 K9SLQ (439/439), 0044 partial K5WXN (439/lost)
and 0102 OE5EYM (559/559). We heard JA6AHB, K4QI, OH2DG and
RA3LE. On 2304 MHz we worked on 23 March at 1500 LX1DB
(559/449), 1511 OZ4MM (449/449), 1520 OE9XXI (569/559), 1535
OE9ERC (569/559) and 1934 F2TU (449/449), and on 24 March at
1646 G3LTF (O/449) and 1906 G3LQR (O/M). We heard on 13 cm
SM3AKW and Moon noise of 0.6 dB. Due to poor weather, we
were not active on 6 cm. In April we plan to be QRV on 23
and 3 cm. We have prepared a new 4.5 m microwave dish with
f/D of 0.42 from meteorological radar for used on 10 GHz. We
plan to enlarge this dish to 6.4 m with an f/D 0.3. To
reduce tree problems it will be centered 10 m above the
ground on a steel tower.
Narc contributes the following --
On Saturday 23 March Michel and I were active on 13 cm for
some hours in the contest. We worked F2TU, OE9XXI, OE9ERC
and OH2AXH for an initial. We also CWNR OK1CA, F1ANH, SM3AKW
and OK1UWA. We were only running 70 W in the shack and a 3.7
m dish. By 1800 most stations had shutdown, otherwise we
were sure that we could have added some more stations during
the evening. Due to a little accident with my left hand, I
could not finish of a bigger PA. It should be on for next
time. We will be active in the 23 cm part of the contest,
but still running the small dish and OZ9CR amp.

(54/53) FM06. We had bad WX during the contest. Four hours
into the contest, the dishes elevation control was broken by
high wind. In March on 432, I contacted on the 16th W2UHI
(559/549) with the moon only a few degs above the horizon,
on the 17th F6ETI (O/O), on the 21st G3LTF (569/559) - very
strong signal, on the 23rd (during the Eur EME contest) W7BBM
(559/559), W4OP (559/449) and W7SZ (549/549), on the 26th
HB9DDO (56/56) - visitor at HB9BBD on SSB, and the 29th W4OP
(559/559) and N2IQ (569/559).
Stig wrote – During the 1st part of the DUBUS contest
I had very limited time. So I spent the available time 13 cm
and worked 10 stations as follows: OH2AXH (559/449), G3LTF
(O/O), SM3AKW (549/549), OE9ERC (569/559), F2TU (559/559),
OE9XXI (579/559), OK1UWA (O/O), JA4BLC (529/549), LX1DB
(579/559) and OK1KIR (449/449). Several of the regular 13 cm
stations were not found and no 13 cm stations was heard
here! On Saturday signals was weaker than normal as I didn't
have time to remove my 144 dipole feed, which was causing
blockade of the 13 cm feed. On Sunday after the 144 feed was
put in the rest position, signals was much better, and in
addition I got the amplifier working more stabile than on
Saturday. I hope to put in some time on 1296 in the last leg
of the contest.
Valeri has finished his new Antenna. He had bad WX -
snow and wind during the contest weekend, but did make
initials on 432 with JJ1NNJ, K4EME and PA0AVS. G3HUL was
heard. Valeri ended the contest with 23 QSOs.
Peter reports working about 30 stations on 432 in
the 1st part of the DUBUS/REF Contest. Among those QSO'd was
OE1SOW (2x19 el yagis and 300 W) for an initial. He also
reports that FR5DN is working on 1296 EME – see the
Carl reports on the 1st weekend
of the Debus contest on 432 -- I made on 13 cm a score of
11x7 and on 70 cm 35x26. On 70 cm most stations heard during
the contest weekend came in on vertical pol. On Saturday, I
spent quite some time on 13 cm. F1ANH was the only new one!
Where were the US and VE contingent? None were heard.
Wilt from (DN62uu) WO reports My
antennas were destroyed in the wind last Nov. I have new
ones started, and hope to be back on the moon in about a
month, maybe less. I also have started to gather 1296
equipment. I have a transverter and 6 x 2C39 amp, so I hope
to be QRV there by the fall. There are no 20' or better
dishes available around here, so I may build one. I will
advise when I am ready on 70 cm.
Frank is back in operation after his squirrel attack.
All systems are go again. He replaced all the chewed through
cabling and tweaked up his drive system. During the SW,
Frank found 23 cm activity reasonably good for a 70 cm
contest weekend. He worked G4CCH, W4OP, F6ETI, IK3COJ, W6HD,
K5JL, OH2DG, W5LUA, W7SZ, W7BBM, K0YW and WA1JOF. Several
more were heard, but no connection. Frank is looking for
info on GR-1236 IF Amplifier. He needs to calibrate it.
Where are the adjustment points to calibrate linearity?
Al had a FB visit in March from K5GW, K5JL and K0YW.
During the SW he had windy conditions, but did get on 1296
and worked W4OP, W2UHI, F/G8MBI, G4CCH, K9KFR [?] and
Larry was QRV on 23 cm in March and worked K9KFR [?]
with a big signal. He was also on 10 GHz and worked G4NNS.
G4NNS was running only 9 W!
Don QSO'd on 1296 during Saturday of the SW K5JL,
W2UHI, K0YW, OH2DG, G4CCH and W4OP. He now has GR-1236 for
John worked 4 new ones during the March contest
weekend. He QSO'd G4HUL, W4ZRZ, JS3SIM, JJ1NNJ, PA0AVS and
F6KHM for an initial #107. Altogether 10 were worked, 23
other stations were called.
Iva writes -- I was really
looking forward to the DUBUS Contest and during the prior
week checked my 13 cm equipment. My Sun noise was just 12
dB, but after few operations of the TR relay, it jumped to
18 dB. There was heavy thunderstorm before the contest. The
1st station heard was OE9XXI. I called him and he came back.
We made it (I hope) and then my power meter went haywire.
Measuring VSWR showed that there was a fault in the TX
cable. Sunday morning I could not find the fault. So started
to check the 6 cm equipment. Sun noise was just 7 dB! Again,
after a few operations of the TR relay, it increased to 14
dB. This was less than before, but good enough. Output power
was 20 W. The 1st station heard was F2TU, just before his
sked with JA7BMB. He was good copy. In their sked, I heard
both. JA7BMB was a bit weaker than F2TU. I could not find my
own echoes at that time. Later I found that the EME program
shows 1.2 kHz lower value of Doppler. At that time I was
tracking only by Moon noise. It was just 0.5 dB. (Lower than
before). After the F2TU sked, I called him and he came back
with a (449) report. He was (559). JA7BMB did not respond to
my calls. No wonder, I was off frequency. Then I installed
the CCTV camera and found my own echoes (up to 529). I again
worked F2TU (569/559) and F1ANH (O/O). After that I called
LX1DB for close to 2 hours with just QRZ in reply. No other
stations were heard. I spent all my time calling Willie for
a new initial. So there went my contest, Hi! On Saturday 30
March, we made it with JA7BMB (O/M) on 6 cm EME. This was
the 1st ever QSO on this band between Africa - Asia and JA
to ZS, and my initial #12. I am quite happy about it. There
was good conditions, but unfortunately no reply for skeds
with LX1DB. Thus I took my CCTV camera out and will take the
6 cm feed assembly down too. BTW - the screening cover of
the 6 cm horn fell off unnoticed, thus I was operating on 23
and 13 cm in past months and no apparent damage was done to
the 6 cm equipment. So the permanent installation of the 6,
13 and 23 cm horns with 6 and 13 cm horns offset seems to be
working well. I can change between bands in a few minutes.
I spent most of the weekend on 70 cm participating in
the contest, although my operating time was limited on
Saturday night by a family activity. QSO'd on 23 March at

2243 DL1YMK (559/559) and 2304 G3HUL? – had to leave as the
XYL was waiting. The next I switched to 1296 for my GM0ONN
sked. I head listened during the earlier sked and heard
consistently a signal I believed was GM0ONN but nil from
VE1ALQ. At the start of my GM0ONN sked at 2230 I felt pretty
confident, but nil was heard – frustrating. At 2250 I gave
up and worked OZ6OL (559/569) followed by at 2300 N2IQU
(56/55) on SSB and 2310 W7BBM (55/55).

W1IPL is looking for a 20' or larger dish. Contact Wilt at
SV1BTR has for sale a 70 cm Siemens 4 pole BPF centered on
432 with a 500 KHz BW and > 100 dB rejection. The return
loss is 20 dB and the insertion loss is 2.3 dB. It is quite
heavy, around 10 kg. Jimmy prefers to ship within EU and is
asking 140 Euro with shipping included.

in HP-435, 6, 7, 8 power meters.
VE6NA is looking for 7289 tubes with screw on caps.
W2DRZ is looking for absolute position encoders.
N2UO has completed assembly of
a 10' stressed dish that may give others ideas on how to
fabricate lightweight and inexpensive antennas for 1296.
Marc's dish is picture above -- It is made of ¾" aluminum
tubing, using the same ideas K2RIW and K2UYH used in their
dishes several years ago. The tubes follow the parabolic
curve within ± ¼", although the surface is a little worse
than that because the aluminum screening is hard to
"persuade" to take a parabolic shape. The screening was on
sale and there was nothing cheaper than it. Chicken wire was
not used because it was not suitable for 23 cm, and hardware
cloth was too heavy and expensive. The antenna is controlled
by an OE5JFL type auto tracker, and is mounted on casters,
so it can be hidden between the house and the pine trees
when not in use, to please the neighbors. I do not plan to
be QRV soon due to time conflicts with required travel, work
and graduate study.
