14.345, 10 AM ET SATURDAYS, AFTER VARO NET SUNDAYS:
The Italian contest generated some extra EME
activity during the May skeds weekend (SW), but activity was
down because of the Dayton Hamvention that attracts amateurs
and EMEers from around the world. The big news this month is
W2WD's dxpedition to Nebraska.
NEB 432 DXPEDITION: The W2WD/0 dxpedition is on. Warren will
be operating during the weekend of 15/16 June from Bill's
email@example.com QTH in Neb. If you have not done so already
contact Joe, K1RQG via the 20 m net or e-mail K1rqg@aol.com
for skeds. Warren will always transmit on 432.030 during the
1st 2.5 min sequence and listen for sked stations on
432.030. He will also call CQ on 432.030 and listen for
random calls from 432.030 to 432.040 unless otherwise
advised. He will be listening 10 kHz (.040) high during
skeds for random calls and will switch over to random, if a
skeds station is not heard. He will be using a portable 20'
dish with pol rotation and about 500 W from a 2 x 4CX300 PA.
Murphy has been around. Warren's 4CX300s started flashing
over, but he has received additional tubes from a number of
sources and this problem appears under control. He has also
been contacted by the 144 EMEers and will try to operate on
2 m as well. He says there seems to be more interest in Neb
by the 144 gang. They are even sending him an antenna. [What
about 1296? Unfortunately it was too late by the time Warren
decided to consider additional bands. I think there is
something here to be learned for the future!]
Guenther now has a terrific signal on 23
cm. He is QRV with a new 10 m dish See his web page at:
Guenther's WEB Page
He will make several
improvements in the next few weeks. The transmission line
will be replaced by a 7/8" Cellflex line. He is also
searching for a long version of an IMU circular feed.
Manfred (PA3GLB/DL5FAB) sends results of his group's
10 GHz EME Activity during the Eur contest -- The crew of DL0EF
Manfred's WEB Page
was active on 10 GHz moon
bounce during the DUBUS Contest on 20/21 April from the
Astropeiler Stockert, located near Bad Muenstereifel
(vicinity of Cologne) in JO30im. We were using our 10 m
dish, polar mount and a 20 W transverter system. Moon noise
was around 3 dB. We installed a magnetic polarizer unit,
which proved valuable for large spatial offsets. We also
replaced a modified satellite LNB with a DB6NT LNA, which
improved the receive path. Increase in the ratio moon noise
to colds-sky could not be observed anymore due to the big
dish size. The activity started as planned, however, we run
into problems with the antenna drive at around 2100 on the
20th, at the time of our sked with W6HD, which did not allow
us to use the required slow gear to track the moon.
Faultfinding revealed a problem with one of the motor drive
couplings. The repair would require a major mechanical
intervention, which was not possible during this weekend. We
tried to continue operation by advancing the antenna in
short but coarse steps and let the moon catch-up. The polar
mount proved very valuable, as we need only to steer in GHA.
QSO'd were on 20 April at 1622 I5PPE (O/449), 1642 G4NNS
(O/O), 1658 F6CSX (439/O), 1734 OH2AXH (529/529) and 2205
WA7CJO (559/O). Also heard but not worked due to the antenna
drive problems were W6YFC, CT1DMK, F2TU and K6RE. We want to
thank everybody for the QSOs and we will be back in the air
later in the year. Our plans are to increase our TX power by
around 10 dB and further improve the control of the dish.
Dave was active on 23
cm in the Eur EME Contest – I QSO on 20 April HB9Q and
G4CCH, and on 21 April F2TU for initial #35, HB9BBD, OZ6OL,
F6KHM #36, OK1CA #37, HB9SV, OE9XXI, SM3AKW, F6CGJ, G3LTF,
OZ4MM, OE9ERC, JA6AHB #38, ZS6AXT #39, K5JL, W4OP #40 and
KA0Y. Just before the contest I replaced my preamp with a
cavity design from K2AH. It proved difficult to get the NF
better than my BV preamp, but finally with help from HB9BBD
and DL4MEA a NF of 0.31 dB was achieved. Since the contest,
I have added in skeds IK3COJ and SM6CKU to bring me to #42.
Juergen in JO42xi has
completed a dish for 23 cm EME and will be QRV during the
June SW. He is measuring about 13-14 dB of sun noise and has
already worked DJ9YW (O/M) and G4CCH (559/529) on random. He
has 100 W at the feed, but is restrictions to AZ from 90-236
degs and EL from 10-50 degs.
Jan sends TNX to IS0/DJ5MN for initial #770 and DXCC
#84 on 432. Jan says Bernhard had a nice (549) signal with 1
yagi and 500 W. Jan also worked VK3FMD #771 (2 yagis and 200
W) in May.
Phil (LG78qs) is now interested in
23 cm EME -- I have a 1.8 m solid dish, f/d about 0.28, and
wonder if it is suitable for some EME work? I know that it's
a small size, but it's hard to use a larger dish, as I would
have to take all down and secured, as soon as there is a
cyclone closed to the island. I have had to do this a number
of times with my 2 m and 70 cm antennas. It's not fun, hi.
For 1296, I think it's really marginal, so I'd like to know
which band would be the best? [You're right about 23 cm.
Some QSOs could be made with a high power PA. Unfortunately
a 0.28 f/d is also very difficult to properly illuminate on
any band. If you want to use this dish, 10 GHz is probably
your best bet. For 23 cm I would suggest construction of a
small stress dish with a mesh covering. A dish similar to
N2UO's shown in the last NL would be a good choice. A 2.5 m
dish would put you in business.] What about JT44 on EME, can
that be a solution for marginal or QRP stations in the
future? [There is growing interest in JT44 and should
definitely help marginal stations. I'd still use a different
antenna on 23 cm – even a long yagi.]
conditions but little activity in May -- On 432 on 18 May I
worked DF3RU, F2TU, UA3PTW, K9SLQ for initial #358 and
IN3AGI. I think he is also an initial but I'm not certain if
he may have been a guest operator. He had a good signal. On
1296 I QSO'd on 18 May I0UGB, ZS6AXT, IK2MMB, JA6AHB,
IK3COJ, G4CCH and W2UHI, and on 19 May on 13 cm JA4BLC
(crossband to 2424) and F2TU (2320/2304). I heard and called
ZS6AXT and SM3AKW, who is now very loud! I now have my new
low backlash gear train, and the moon following system is
working FB. I reckon to be within about 0.5 degree of the
moon, which makes a big difference, especially on 13 cm. My
next job is to re-cover the center 4 m's of the dish and
trim its profile in preparation for operation on the higher
bands. I'm hoping very much to work W2WD in Neb, which will
leave only KY and WY for WAS!
Doug has problems back in
April -- Despite spending a day checking out the station for
the DUBUS contest, I was plagued with Murphy. I had problems
for most of the session with my AZ readout and low output
power. Even after all of that I still had an enjoyable time
with some outstanding signals. HB9BBD was hitting S7 over
noise in 1 kHz bandwidth. I worked 8 stations with 6
multipliers. My station is a 10' Andrews dish on an AZ/EL
mount with a VK3UM controller, VE4MA feed/DJ9BV air hybrid,
WD5AGO preamp, TX YD1336 cavity with only 300 W out (but
when drive is ok 500 W).
Vico, (I4ZAU) reports that his group
was active on 10 GHz again during the May SW -- We worked on
18 May at 1503 IW4BTJ (519/52), 1531 I5PPE (O/O) and 2025
I4CHY (52/52) for 1st Italian two way SSB, and on 19 May at
1532 F2TU (O/O). Our station consisted of a 7 m Cassegrain
dish, 60 W TX, 1 dB NF LNA in JN54vj (Bagnara di Romagna,
Italy). The crew was I4BER, I4QIC, I4TMA, IW4BYP, IW4APQ,
IZ4BEH and I4ZAU (ex I6ZAU). We plan to be QRV again for the
June SW, and on 24 GHz next year.
Cowles suffered a lightning hit in
April that took out a lot of his equipment -- The azimuth
rotor is dead along with my FT-736R and tracking computer.
It appears that my 70 cm PA was unharmed. I had good grounds
and surge protection on the antenna system. The strike
appears to have come in on the phone lines. My bell box is
in sad shape. I am in the process of getting things fixed,
so I hope not to be down for long. I will let you know when
I will be ready again for EME skeds. The good news is that I
have acquired a 6.1 m solid aluminum dish.
Jeff CM97qi ran skeds on both 432 and
1296 with SM2CEW during the May SW. He heard nil in both,
nor any random activity. He uses on 432 2 x 9 wl yagis and
300 W, and on 1296 a 3.3 m dish and 100 W.
Marc has finished the surface of his 10' stress dish,
and almost has everything else is ready for EME operation.
The auto track is working and is getting 14 dB of sun noise.
He hopes to be on 23 cm after a couple more days of work
with low power (about 50 W at the feed) as he still needs to
get his high power PA finished..
Franta is preparing equipment for 9 cm
EME -- I have a 3 m dish with linear feed (vert or hor pol),
FT736R and TRX with 15 W at the feed and a ATF36077 W5LUA
LNA. My sun noise is 15.4 dB (SF162) and my moon noise is
0.5 dB. I have heard own echoes (M). I have a frequency
problem, as the OK ham allocation is 3400 to 3402 MHz, but I
can listen in the 3456-3458 MHz band. I tried a sked with
W5LUA on 24 May, but I had a problem with my T/R relay. My
rig is now ok and I am interested in skeds on 9 cm.
Jac in JO21hm is now QRV on
13 cm EME (TX 2320). He can also RX on 2304 and 2424.
Equipment is 2.50 m dish with VE4MA feed with built-in
circulator, 30 W at the feed and 0.6dB NF. Jac is interested
Rajko and Sil say -- "Punk is not
dead" and S59DCD also is not, hi, just a little sleepy for a
while. After our 1st successful 13 cm QSO with OE9XXI last
Oct, we rested until now. In the May and June activity
weekends S59DCD will be QRV on 13 cm with our 6 m dish and
about 70 W for anyone who needs S5 on 13 cm. Skeds are
welcome – see my new e-mail address above. Otherwise we'll
see you in Prague.
Charlie in QF22mc is trying to
arrange for some 70 cm EME skeds -- I am a small station
with 21.6 dBi antenna gain and 200 W, but no elevation
control (yet!) I have had success on 2 m EME with the bigger
stations and the EME bug has bitten and I would now like to
try 70 cm. [There is a big advantage to getting off the
horizon, even with a fixed tilt on 432. This is because of
the much lower skynoise.]
Frank as usual was QRV on 23 cm in May. He worked
ZS6AXT, IK3COJ, G3LTF, G4CCH, W7BBM, DF4PV, IK2MMB, OZ4MM,
F2TU and HB9BCD for initial #157 - all with good signals. He
says his system is working well, but won't be active during
the June SW due to family commitments.
Wilt in DN62uu is working on 70 and
23 cm EME and updates his status -- My station on 70 cm is
basically operational. It consists of 6 x 22 el "FO" yagis,
.5 dB NF MGF1302 LNA, 80' of 7/8" line and an FT847 driving
a single 3CX800u7 to 450 W. A GS35B PA a'la' PA3CSG is on
the way to completion. On 1296 I will advise when things are
further along. I have a 6 x 7289 PA, but lack a driver,
preamp and dish feed. My transverter is a real nice 10 mw
job I "liberated" from WA4OFS. I will probably use a 10'
TVRO dish, but the antenna is not yet decided. We are in a
rental house and the winds are hellish here.
Dale moved in May of 2000 from EL96 to
EM85 -- I am a initial for those stations working me on 23
cm. I worked 29 stations in the DUBUS Contest and am now at
initial #53. My future plans are to expand the dish from 12'
to 14' and get my YD1336 cavity playing. Currently, I see
17.2 dB sun noise at SF=190.
Szigy writes that he has no
interest in JT44 .It is sure a nice technical achievement,
but certainly will not help us to get better EME traffic
skills and knowledge. It also is a pity that now a days the
number of EMEers NOT interested in swapping QSLs and photos
(even via e-mail) is growing and the commercial interests
are always pushing back the EME traffic. Being myself a
"traditionalist" I have unsubscribe from the Moon-Net some
months ago. I have now decided to not take anymore EME skeds
and to abandon the QSL traffic as we still do not have the
"outgoing QSL bureau" of our association! I always will be
pleased to make EME contacts on random with my old EME
friends and show their QSLs and pictures to my visitors.
Ivo has a bit of a late report
because of an emergency -- Very poor participation in the
Italian Contest plus some cable failures and a 6 m opening
cut my score this year. My shorter moon window did not help
either. On Saturday 18 May I started on 23 cm by working
JA6AHB, SM3AKW, F2TU, G4CCH, IK2MMB, G3LTF, DF4PV, OZ6OL,
SM6CKU, W2UHI, K9KFR, OZ4MM and W7BBM on the horizon. CWNR
was IK3COJ. On Sunday I started on 13 cm by working JA4BLC
and F2TU, then as I was fitting the CCTV camera to the dish,
I did something to the 13 cm TX cable and I could not find
the fault! So I went back to 23 cm and worked HB9SV and
I0UGB for initial #180. Then I QSY'd to 6 cm and worked
F2TU, but nil was heard from I6PNN, and back to 23 cm for
IK3COJ - came back to my CQ, GM4ISM #181, W7SZ, SM2CEW and
CWNR HB9BCD. This was quite a poor score with the exception
of the 2 initials. I had good weather with the exception of
some wind on Sunday afternoon. On Monday while lowering the
dish elevation to remove the camera, the AZ drive chain
slipped (it was quite stretched already) and dish went wild,
probably damaging some cables. Quick single-handed temporary
repair of the drive in the afternoon allowed the dish to be
safely parked. Since then, we had a cold front passing, so
no idea yet what else is damaged, but hope for not much
damage and expect to be QRV in June.
I did not get in much EME operation during the May
SW, because I was at Dayton on Saturday. I did meet some of
the EME gang there, but I did not see as many as in the
past. Tom, K2AH said that he and Marc, N2IQ left on Saturday
morning. I was active on 1296 on Sunday, 19 May. There were
a number of stations on looking for Italian EME Contest
points. I QSO'd at 2135 G4CCH (559/439) and (55/55) on SSB,
2151 F2TU (55/55) on SSB, 2159 DF4PV (45/55) on SSB – big
signal, 2210 W7SZ (559/559) and 2240 W7GBI (559/559). It was
good the hear Charlie active again. G4CCH told me that ON4QQ
is now QRV on 23 cm, but I did not hear him on. I now have
JT44 installed and am interested in skeds on 432 and 1296.
