CONDITIONS:
On 23 cm signals were good and contest activity plentiful,
but not as great as I had hoped for ... and dropped precipitously
during the wee hours in Eur. I think K1FO is right about the effect of
"time" on activity. He feels we should schedule for preferred
operating time periods, not around Perigee and high dec. 432 activity
was higher than expected, especially considering the conflict with the
1296 contest. On 22/23 March the spot light will be on 70 cm and the
bands 13 cm and above.
- 7M2PDT:
- Shu writes -- Since my last report I worked on 7 Feb JA9BOH,
JA6XED (O/O) for initial #9, IK5WJD (M/M) #10, on 12 Feb JR9NWC (M/M)
#11, on 17 Feb, JA2KRW (O/O) #12, on 26 Feb JA5OVU (O/O) #13, and on 2
March JA2JRJ (O/O) #14 and UR5LX (O/O) #15. I will replace my current
4 yagi array with 8 x FO25s in the near future.
- DF0SHY:
- Christoph (DF9CY) reports -- I was on with DL0SHF on Saturday
night of the contest, and worked on 23 cm: SM3AKW, JH3LUZ for initial
#57, F2TU, HB9SV, JA4BLC, DD1XF, F1ANH, F5PL, HB9BHU, F6CGJ, OZ4MM,
OE9XXI, LA8LF, OE9ERC #58, ZS6AXT, OH2AXH, F5AQC and SM2CEW. I found
conditions changing rapidly with echoes loud and lot weaker minutes
later. We will be on 10 GHz on 23 March - skeds are most welcome! In
the future we will be concentrating on making major changes to the
whole system. We hope to minimize cable losses on 23 cm, and become
QRV on other microwave bands.
- DL4MEA:
- Guenter emails some news of his EME activities -- The last
time I operated EME was during the ARRL contest. I finished my
antenna, and used it with success for the 1st time, during this
contest. Since then my personal life has been very busy - particularly
on weekends, and I have not had as much time as I would have liked for
EME. [There are a few other things in life besides EME, but not many!]
Skeds are always welcome Monday - Thursday evening between 1800-2100,
weekends only on direct appointment (dl4mea@amsat.org or
http://www.scn.de/~koellner). Regarding my operations, I still have to
improve my reception. The rig is IC475, home-brew K2RIW (new pair of
4CX250s and stable 2.3 KV supply), MGF1302 preamp (DJ9BV style) and
home-brew 6x33 el DJ9BV's OPT-70 yagis.
- EA6/DF5JJ:
- Peter received bad news from Mallorca. His dish was totally
destroyed by a big storm. He has not yet returned to asses the full
damage, but will not be QRV in March. He is scheduled to return to
Mallorca on 15 March. Peter also reports that he gave a lecture on 23
cm EME to a microwave group in DL. The response was so positive that
he predicts pile-ups on 1296 from all the new comers!
- G4DZU:
- Doug writes -- Things weren't too good in the 1st part of the
DUBUS contest. The moon was just getting to the end of my window at
0000 on 2 March. But I couldn't hear anything off the moon, the local
beacon was down about 30 dB, so I took the right decision and went to
bed. Once it was light I found I'd forgot to screw down an SMA
connector, when I mounted the pre-amp on the feed, tut, tut. Due to
problems with the cathode bias, I was only running 100 w at the feed.
This is not enough for reliable contacts with my 10' dish. On 2 March
I did QSO OE9XXI and OZ4MM, and on 3 March LX1DB for initial #12. I
CWNR F1ANH and F6CGJ. I will be QRV again during the 2nd March SW. I
was also active in the Feb SW, with 400-500 w in the shack and about 2
dB of feeder loss. I guess that things are finally working OK as I can
hear my echoes, faintly, in 2 KHz BW. On 3 Feb I was up till 0300
local and QSO'd KB2AH (569/449), N2IQU (559/449), CWNR AA6WI - he was
hearing too much ground noise at the time, heard SSB QSO between KB2AH
and K5JL. On 4 Feb echoes were FB, until I called K5JL. There was an
almighty bang as a flash-over in the PA tripped the ckt breakers and
took out the bias transistors. As it was 0100 local, I decided to go
to bed, and missed a sked with WB5LUA - actually I did not learn of
this sked until the following day. A good way to arrange skeds with me
is via Internet. I access my mailbox at least every day. My email
address is Doug, G4DZU
- G3SEK:
- Ian goes back to Nov to catch up on his reporting -- In Nov,
including the 2nd part of the ARRL contest, initials were W8MQW (O/O),
CN2EME (559/559), JS3SIM (M/M), DL6NAA (O/O), F5FLN (449/449) and
F5HRY (O/O). Dec brought initials with HP3XUG (O/O), DK8LV (M/O) and
W9QXP (O/O). In Jan I had some RX problems due to water in the RX
feedline, that also carries 12V DC - never heard "electrolysis noise"
before! The only QSO was with LX1DB (559/559). K3HZO was (O/T) on sked
- a good signal in spite of the problems. Feb was also a quite month
for me due to lack of time - nil from JR9NWC on sked, and worked only
K1FO (549/549) and K5GW (549/549) for another initial (#). March was
also time- limited due to home improvement activities, but I did work
JA2KRW (439/449) # when testing on Friday mid-afternoon, W7CI
(449/449) and KD4LT (559/549) Friday night, and KA0RYT (O/O) # on
Saturday evening. The QSO with KA0RYT was a special treat for MN and
WAS #40 - my 1st new state in six years! This brings my 432 EME
standings to #238 initials, 50 countries and 40 states. Polarization
rotation continues to provide many QSOs that would have been
completely impossible on fixed horizontal pol, and quite a few that
would have been much more difficult with only switchable Horz/Vert pol
only. Unfortunately, family commitments have targeted the two most
important EME weekends of the spring and summer, so I won't have much
operating time for the 432 MHz part of the Eur/DUBUS contest, and I
won't be able to come to the EME conference. But I'm DETERMINED to go
to Weinheim in Sept and hope to see some folks there.
- JA4BLC:
- Yoshiro has important news on 5760 EME from JA -- Our radio
authority told me that I had been given wrong information concerning
possible frequencies for 6 cm EME operation. As a result of to their
mistake, I have obtained a special license for 5760-5762 MHz EME
operation! I have 25 w and am 1st ever in Japan. I will do my best to
finish the station quickly. On 2/3 March I was primarily active on
1296. Despite the failure of my TH308 PA, I managed to install my old
7289s amp in the rack, and get 300 w out. I worked DL0SHF, OH2AXH,
F6CGJ, F1ANH, F5PL, F2TU, OZ4MM, SM3AKW, OE9XXI, HB9BHU, VK5MC,
JH5LUZ, JH3EAO, OZ4MM dup, ZS6AXT, OK1KIR, I2COR and DF3RU during the
weekend. Heard but not worked were VE6TA, HB9SV and SM5DGX. On Sunday,
I replaced the 1296 MHz preamplifier at the feed. The old MGF1302 (NF
0.6 dB, gain 17 dB) was replaced with an FHX35LG amp followed by an
MGF1200 (NF 0.3 dB, G 35 dB). This increased Sun noise vs. cold sky
noise from 12 dB to 14 dB! I will be on 2304/2424 MHz during 23/24
March contest/SW. (My email address is
Joshiro, JA4BLC )
- JA9BOH:
- Kimio was not active on 23 cm this past month due to WX
problems. But reports that JH1WLK, Sigeru Motohashi, is now QRV on
1296 with a 3.8 m dish and 100 w HPA. His mail address is
Kimio JA4BOH. Kimio plans to back on 23 cm in the Spring
with a bigger ANT and AMP.
- JR9NWC:
- Hideyuki's EME QSO results for 2 March follow -- partial
JR9NWC K5WXN (M/?), nil JR9NWC W9QXP, nil JR9NWC WB2VVV, nil JR9NWC
W7FN, nil JR9NWC KB8ZW, nil JR9NWC K5JL, nil I5MPK JR9NWC, nil IK1MTZ
JR9NWC, nil F5HRY JR9NWC, nil DL8OBU JR9NWC, nil G0RRJ JR9NWC and nil
PA3CSG JR9NWC - QRM from snow noise on the last 3 of these skeds. His
system consists of 8x21 el hor pol yagis, FT726 and 3CX800A7-2 HPA and
MGF 4318D LNA to+SK406/CONV and TS950 plus DSP.
- K1FO:
- Steve again found good activity from Japan on the weekend before
the SW. He feels that JA - NA skeds should be made on weekends such as
this with local moon time at reasonable hours. He worked on 24 Feb
KA0RYT, JA5OVU, JA2KRW and JR9NWC, on 25 Feb N4PZ and JA9BOH, on 02
Mar K5AZU - good to hear Ray back on after a long absense and with a
real big signal, also worked on 02 Mar were WA7BBM, KA0RYT and ON4KNG,
on 03 Mar W7CI, DL3YEL, DL9NDD and WA6BJE, on 04 Mar N4PZ, NC1I, VE6TA
partial, he was sending 'K2UYH', VE6TA complete QSO and W8MQW. Steve
missed his 7M2PDT sked due to the late time that it was at. Conditions
over the 2 weekends were again excellent with little Faraday rotation.
Steve expected low activity with the 2 m and 23 cm contest on the SW,
but he was surprised to hear reasonable NA activity, but almost no
activity from Eur. Conditions over the two weekends were again
excellent with little Faraday rotation. Steve is looking forward to
the REF/DUBUS 70 cm Contest weekend and the arrival of Spring.
Although he has not had any damage to the array, winter has been
absolutely miserable with a new all time snowfall record for CT (100"
/ 2.5M) and still counting! This broke the old record which was set
only 2 years ago! Steve's 70 cm EME totals are #487 initial, 49 states
and 74 DXCC.
- KD5RO:
- Dave writes -- Since my last report, back in June, I worked on
23 cm EA6/DF5JJ for initial #55, KB3PD #56, DD1XF #57, EA3UM #58,
VE3BQN #59, OK1CA #60, DJ9YW #61, DF9QX #62, VE6TA #63, VE1ZJ #64,
K3EAV #65, OH2AXH #66, HB9BBD #67, VE1ALQ #68 and JH3EAO #69. In
addition, I've had several SSB QSO's, even with the 160 w level I've
been running. On 8 April, I worked OE9ERC (57/43) and KB2AH (56/43),
on 6 May OE9XXI (57/43) on SSB, on 5 Nov DL9EBL (58/55), and on 3 Dec
KB2AH (56/42). This past Fall, I began work to finish up my UPX-4 6
tube amp. I sent the cavity to KB2AH, who had offered to finish the
machine work, and as luck would have it, it got lost on the return
trip to me. Fortunately, Tom had insured it, so when the settlement
was made, Tom sent me one of his 6 tube beauties. I had it ready to go
as a surprise to Tom and others for the last SW (Feb), but once again,
Murphy struck! I was getting a very stable 600 w out and was echo test
ing the night before the SW when my plate transformer decided it had
had enough of 1.5 amp peaks and let go. I am still working on finding
another- can anyone help? I also made an attempt to get on 3456 this
past Fall to work WB5LUA, VE4MA and DL9EBL. I have 50 w at the feed of
my dish and a 0.6 dB NF. But, when I put the feed in the dish, I
couldn't find the Sun (or the Moon, of course). So, no joy. The
problem turned out to be a feed offset problem caused by the constant
high winds we have here. The feed support is a "button-hook" type and
when the dish is stowed, the feed is vertical, of course. The wind
beating on the support caused it to bend slightly, causing a 6 deg el
offset, which I hadn't noticed. Well, when I looked for the Sun, I
never went 6 deg from where it should have been, so I never found it
and assumed something else was wrong. Now that has been fixed, and as
soon as better WX comes, I'll try again to get back on 9 cm. I have
one comment to make: I am concerned (as are some others I've spoken
to), that EME QSL'ing is becoming less popular, at least on 23 cm. I
am surprised at the number of stations who have stated that they are
not interested in QSL's (several Stateside and at least one European
recently). It used to be the case that a QSL was the final courtesy
for a QSO. There are those of us who enjoy sending and receiving QSL's
as confirmation of the contacts which, though they may not be that
much of a challenge to some, certainly still are to others. I take
pride in my notebook of QSL's and pictures from the EME stations I've
worked, and I guess I thought that was the way it was with all the
others of my kind. I doubt that the excuse of the expense of QSL'ing
can be made - I don't know of anyone in this part of the hobby (EME)
who would be financially strapped by the expense of a few QSL's now
and then. No matter what ANY of the "Big Guns" say, there is still no
guarantee that you will work a station who comes on the air, and the
QSL is the trophy of that contact. By the way, I still need QSL's
from: OE9ERC, VK5MC, EA6/DF5JJ, VE3BQN, VE1ZJ, and HB9BBD.
- PA0PLY:
- Jan's group is worked to upgrade there 23 cm EME capabilities.
Back in the ARRL contest using a 2 m dish with a 2 x 7289 PA running
about 150 w, they worked OE9ERC and OE9XXI on sked and IY4ARY on
random. Jan's asks about QSL info for IY4ARY? [Try contacting I4BER.]
They are now working to improve their 1296 system. They are
constructing a 6 m dish and new HPAs using YD 1060 and YD 1333
tubes... but do not expect to have the new system ready in time for
the DUBUS/REF Contest.
- VE1ALQ:
- Darrell says that none of his Mar skeds were completed -- I
did hear S59DCD (?) on one sequence only at the 20 min mark. I had to
leave the moon on 2 Mar with 56 deg of el remaining due to ice in my
AZ encoder drive chain that caused the sprocket to drop off the chain.
I did get it reinstalled for the 2nd night, but again was forced off
the moon at 48 deg (el increasing) due to 55 cm of snow fall and very,
very high winds (the worst storm of the year at this QTH). VE4MA was
my last entry at 0136. I did work a total of 20 stations in the 23 cm
portion of the contest and managed to pickup an initial with DD1XF for
#60, so all was not lost. I found condx much better on the 3rd in
spite of the storm. Far less libration than on 2 Mar. I also worked
WA4NJP on a sked at 0240 on 5 Mar for initial #61.
- VE6TA:
- Grant sends a list of stations worked during the 23 cm segment
of the Eur Contest -- I QSO'd on 2 Mar OE9XXI (559/449), OZ4MM
(449/429), KB2AH (559/439), VE1ALQ (449/329), F6CGJ (O/O) for initial
#41, F1ANH (O/O), F5PL (O/O) #42 and N2IQU (549/539), and on 3 March
DJ9YW (O/O) #43, K2UYH (O/M) and OE9ERC (55/33) on SSB. I also had a
couple skeds with JA4BLC, but not much luck as my azimuth calibration
is not very accurate in my western window, especially with a major
storm blowing. Sunday evening despite high winds, I was able to get
the 70 cm array on the moon and was pleasantly surprised by the
activity. I worked NC1I (549/439), ??? called and K1FO (O/O). I hope
to be on 70 cm for the next contest segment, work schedule allowing.
W4HHK: Paul had no luck with his 13 cm skeds on 2 Mar. Nil was heard
from HB9SV. On the 3 March he did better, and worked WB5LUA (459/449)
and OH2AXH (O/O-459) for initial #30. He asks stations to look for him
on 13 cm during the coming contest weekend.
- ZS6PT:
- Pete's dish was damaged in a bad storm last Dec. He had to pull
the whole antenna down for repair. But its now back in place. He is
working on a solid state HPA, and is having a difficult time locating
devices. Can anyone help him locate some Motorola MRF392s. Peter's FAX
is +27-11663-6676.
- K2UYH:
- Mother nature was a little kinder to us this SW. We did have
snow again, several inches, but there was no wind. I was, thus, able
to leave the dish tilted over to minimize accumulation. It was also a
little warmer. This reduced problems with ice on the dish track. Our
only problem was lack of Eur activity during the prime hours of our
limited moon window. Hank, KC2TA assisted with operation on Saturday,
but was unavailable on Sunday. QSO'd on 2 March were at 0003 SM3AKW
(559/559), 0019 F5PL (559/549), 0056 OZ4MM (569/559), 0107 F2TU
(559/549), 0114 F6CGJ (559/559), 0126 OE9XXI (579/569), 0134 HB9BHU
(559/559), 0140 N2IQU (579/569), 0143 KB2AH (589/569), 0157 K3EAV
(559/559), 0204 F1ANH (559/559), 0207 K5JL (569/559) and 0211 AA4TJ
(559/559), and on 3 March at 0009 F5AQC (559/559), 0014 OH2AXH
(559/559), 0018 ZS6AXT (559/569), 0025 W2UHI (559/559), 0031 LA8LF
(559/569), 1117 WD5AGO (559/559), 0126 VE6TA (339/O), 0137 OE9ERC
(55/56) on SSB, 0144 OK1KIR (559/559), 0206 VE4MA (559/559), 0210
partial DF3RU (559/-lost) and 0848 JH5LUZ (O/O). Got aways include
VE1ALQ and a JA??? who called us after JH5LUZ - too much ground noise
and attenuation from the trees. We were also listening during the JA
window on 2 March, but heard only K3EAV. During the 2nd contest
weekend we plan to be on 432.
