14.345, 10 AM ET SATURDAYS, AFTER VARO NET SUNDAYS:
CONDITIONS
This month's emphasis has to be on the Prague EME
Conference. The OK-group did a terrific job organizing the
conference, which came off without any real hitches despite
concerns over flooding. We arrived in Europe to news of the
disastrous floods. Fortunately the conference site was located
on high ground far from the flooding. By the conference start,
the water had receded to the point where it was possible to walk
along the river's banks. Nevertheless many of the tourist sights
near the river were closed as well as the main train station.
This latter closing caused travel complications for a few
attendees, but the resourceful Czech organizers had work around
solutions. As a result more than 100 EMEers (plus 80 spouses)
attended with all continents represented except S. America.
A major topic of the conference was the new digital modes
starting to be used on 70 cm and above EME. Both Joe, K1JT and
Lief, SM5BZE gave presentations. Lief has developing computer
processing techniques that allow the copy of normal CW at signal
levels lower than with the ear. His approach can be considered
the creation of a "super audio filters". He also advocates
simultaneous reception of vertical and horizontal polarization
separately and recombining them to produce the optimum
polarization. This approach is applicable to 144 and 432 where
linear polarization is used and Faraday rotation is a problem.
It is not clear if there would be any advantage on 1296 where
circular polarization is almost universally used. K1JT announced
a new version of his JT44 software to be available shortly with
an echo test mode. VE4MA's talk on how EME was achieved on 24
GHz and current efforts on 48 GHz received a standing ovation.
Among the recommendations of the conference was the use of
circular polarization on the EME microwave bands (including 3
cm). There was also considerable discussion on how to get
operation on the different 13 cm sub-bands required around the
world. Peter, G3LTF discussed the benefits of using a common LO
in order to maintain a fixed offset in each segment. It was
agreed to use CQX when listening for stations in a different
sub-band. Some of the most intense discussion centered on JT44.
Many stations felt that JT44 QSOs should not count for DXCC,
WAS, initial counts, etc. Ian, G3SEK pointed out that the rules
for awards as DXCC and WAS are set by the organization and do
not differentiate by mode. I noted that the key issue is what
constitutes a QSO. JT44 contacts do not appear to violate the
definition of a QSO, and can occur in less time than a typical
weak signal CW contact, so time delay is not factor. It was
agreed that the recommended JT44 CQ calling frequency be 432.044
and 1296.044, not on .024 as proposed in last month NL. It was
also decided that the 2004 EME Conference will return to New
Jersey after 14 years. N2UO will head the committee and planning
has started to make the 2004 conference one that no one will
want to miss.
BY7BJA
Feng in China has been again in contact
with WA4NJP. Ray sent him information on JT44 and received the
following reply -- I changed my jobs last year. I went to a
middle school to do some management work, and was away from my
station. I am returning to teaching next month and will be back
near my station. I will try to do something on EME, but I need to
work on my system first. Thank for your information, I will ask
for more details after I finish checking out my system.
DL8OBU
Juergen writes -- I just
modified the roof of my house (two tiles had to go!) to avoid its
touching the dish. Now I can operate with elevation from 20-60
deg over the full range of azimuth. I have now worked the
following stations on 1296: N2IQ, KA0Y, VE6TA, SM6CKU, LX1DB,
HB9Q, JA6CZD, HB9BBD, WA6PY, SM3AKW, OH2DG, K2UYH, IK2MMB, W5LUA,
VE1ALQ, W2UHI, G3LTF, F1ANH, GW3XYW, JA6AHB, K5JL, DF4PV, OZ6OL,
DJ9YW and G4CCH with my 3.1 m dish and 100 W to the feed. Skeds
are very welcome. I'm still QRV on 70 cm EME and interested in
sked there too! I have 4 x 33 el yagis and a YL1500 PA. I plan to
shut down on 432 EME next spring, so if anyone still needs me,
please get your skeds in now! I am waiting for QSLs from W2UHI,
VE1ALQ, W5LUA, IK2MMB, OH2DG and N2IQ.
ES5PC
Viljo in Estonia (KO38hj) is QRV on 2320 MHz EME and made
several QSOs in Aug. He is using linear polarization with a 2.6 m
prime focus dish, f/d = 0.35 on a polar mount. The feed is a
patch antenna. TX power is 350-400 W to only 3 meters of ½"
cable. RX NF is about 1 dB. His moon window azimuth range is
currently limited to between 160 and 260 degrees. At the time of
Viljo's correspondence, he had copied SM3AKW (339) and has since
QSO'd several stations.
ES8X
Andy, ES2NA reports on a VHF/UHF dxpedition
to Kihnu Island (KO18xc) organized by the Viimsi Radio Club
(ES2WX). This portable operation involved operators ES2NA, ES2QH,
ES2RJ, ES1DW, ES2EZ, ES1LAA and ES1TGO. They were QRV from 30
July until 6 Aug. Their activity included EME on 70 cm using 4 x
12 el yagis with elevation rotator, 300 W PA and FT 847 with a
preamp. I know they worked SM2CEW and at least one other station
using JT44 - [see my report]. They also tried 1296 EME with a
single 44 el yagi (no elevation) to a low loss cable to an 160 W
PA and TS790 with a preamp, but I do not believe they made any
EME QSOs on this band.
F1EHN
Jean-Jacque
expresses disappointment
that the 3 cm band scores were somehow missing from QST in the
ARRL 2001 EME Contest Results. The F6KSX EME Group with which he
is associated took first place on 10 GHz. The correction was
published as a Feedback item in the June 2002 issue of QST on
page 90. I am sure QST's staff will not make this mistake again!
The F6KXS entry was a Single Band 10 GHz multi-operator with a
Score of 18x11 for 19,800 points. The operators included F1EHN,
F1SXC, F4UPG, F6DLA and F6ECX.
F5VHX
Graham has a new call (formally F/G8MBI and F/GOVBA). He
was on 23 cm on 10 Aug and worked SM2CEW and others. VK3UM was
visiting with Graham prior to going to Prague.
GW3XYW
Stu July and Aug EME activity report
I was QRV on 13/14 July on 10 GHz only. Saturday was spent on
Moon noise tests (1.4 dB). On Sunday I worked OK1UWA (M/M). This
was my second 10 GHz EME contact. The first was with PA3CSG back
in Aug 99. In Aug I was activity on Sunday the 4th on 23 cm. The
following stations were worked OH2DG (559/559), G4CCH (559/559),
OZ6OL (569/559), K5JL (549/539) and SM2CEW (559/559). For
possible 10 GHz QSOs with GW please note that I am now QRV again
with 12 W and a HB 2.7 m (9') dish. I plan to be available on 3
cm for the next few months. Please sked via the newsletter
(K1RQG) or direct e-mail (see above).
K0YW
Bruce was active during the post SW in Aug on 1296. He
worked ZS6AXT, W2UHI, G4CCH, W7BBM (3-way on SSB), OZ6OL, G3LTF
and IK3COJ. He also QSO'd N7AM on SSB and gave a demo of EME for
visitors doing some work for Jack. The system seems to be working
well. Bruce also says that he is trying to catch upon QSL cards.
K1FO
Steve has been very busy the last few
months and has not had a lot of time for EME. He was QRV on 10
and 11 Aug calling CQ for the better part of 3 hours between the
2 days with nothing heard but his own echoes. Back in the
DUBUS/REF Contest Steve had 57 QSOs on 432 with 1 initial (JA8IAD
#603) [The top contest score!] Within the next month or two
Steve expects to reach another milestone as he is close to making
his 6,000th 70 cm EME QSO!
K1RQG
Joe is making progress on his dish repairs –
The dish is almost complete. I just need to put new screening on
and then concentrate on the new mount. I hope I can get it back
up this year. I have way too much work and it has been extremely
hot. Willie (W1ZX) is here and we are working as much as we can.
Please bring up schedule requests at the Prague Conference. [It
was done.]
Specific sked requests need to include the requested
callsigns (not simply "new ones"), the requesting station's
window in date and UTC time, and band. Also I need these requests
the weekend following the last skeds weekend (SW). This gives me
time to properly plan the skeds and check out the request. If
stations do use "Moon-Net" for sked requests, and also want me to
sked them, please copy me on the request.
I do not do anything
with moon net postings unless specifically asked to do so. [At
the conference the skeds situation was discussed. Everyone seemed
to favor the SW concept, but agreed that the majority of skeds
are now made directly via e-mail/Internet. It was recommended
that
1) direct skeds be made for the SW, if at all convenient,
2) K1RQG be copied on all such skeds so that they can be added to
the skeds list,
3) an updated skeds list be publicized.
Presently the skeds list is update to DL4EBY's WEB page and sent
out with Joe's Netnotes. My idea was to include this "updated"
skeds list on Rein's (W6/PA0ZN) EME WEB page with the latest NL.
A link directly to it could be included with the NL and also
K1RQG's Netnotes, which would also include the latest sked list.]
K5JL
Jay added an initial on 23 cm on Saturday of the Aug SW
with ON4QMT (?) and is looking for information on this station.
[ON4QQ is a new station on 1296 that G4CCH has reported QSOing.]
Jay also reports that OH2DG was on with great signal, but overall
Aug activity seemed very low.
KA0Y
Ken was on 1296 during the Aug SW and reports contacting
OZ6OL, SM2CEW, K4QI, W2UHI, OE9ERC and N2IQ. He plans to be
active on 23 cm the next few weekends.
KU4F
Thorton is temporarily QRT. He suffered some wind damage to
his azimuth drive and a lightening hit. He will be off air until
he has a chance to make repairs. He hopes to be back on by mid
Sept.
LU6DW
Marc found the last two activity weekends
very interesting on 23 cm -- I worked on 3 Aug OH2DG, G4CCH and
W2UHI, on 4 Aug SM2CEW, OZ6OL, OH2DG and W5LUA, and on 10 Aug
ZS6AXT, G3LTF, VE6TA, W2UHI and G4CCH, on 11 Aug OH2DG and OZ6OL.
This last weekend, I worked on 31 Aug K5JL, PA3CSG, G4CCH, OZ6OL,
DF4PV and HB9SV, and on 1 Sept SM2CEW, K5JL, OZ4MM and OH2DG.
Only 2 QSOs were scheduled. I have been lucky working random or
calling CQ in spite of my small system (260 W at the feed and 3 m
dish). Also I finished my new IF rig and I am very pleased with
its performance. It is a 14 MHz CW/SSB monoband transceiver, all
solid state. It is as small as any modern commercial radio. On 20
m it delivers 100 W. It is based on a Qualcomm DDS, so no
traditional PLL synthesizer was used. The radio is controlled by
an 8052, and has an alphanumeric display that shows the actual
operating frequency (14 MHz or 144, 432, 1296, depending on the
transverter in use). It has a very sharp crystal filter at the
IF, and due to the low phase noise and diode mixer, its dynamic
range is very good. I can now hear weak stations even if my
neighbor K2UYH is 1 kHz from my frequency working CW. The radio
also has a dual product detector with a quadrature BFO, so
binaural reception is possible. I also added a feature to have
not only the classic RIT, but also TX incremental tuning, so I
can program the required Doppler shift quite easily. Right now I
do not use any kind of commercially manufactured radios to
operate.
N4PU
N4PU was QRV on RX on 23 cm EME and getting
16.5 dB of sun noise, but was hit by lightening and had a lot of
stuff zapped. His equipment is now on the mend. The dish is down
and he working on a different mount for his feedhorn. Jim wants
to get rid of the shepard's crook mounting. It is an 8 rib mesh
C-band TVRO type dish. Any ideas are welcome.
N7AM
JAck is now QRV on 23 cm EME with 670 W
off the moon -- This is real living now that we can hear and xmit
on 1296. We finally located the focal point on the dish, so now
everything seems to be in place to make a good effort. It was
indeed a pleasure to work W2UHI this AM [11 Aug]. His sigs were
the loudest heard! We also QSO'd K0YW, ZS6AXT, G3LTF and G4CCH,
and heard VE6TA.
OH3MCK
Petri has moved to Denmark --
I'm QRT for most of the time in the near future because of my
move. However, I can be QRV on 70 cm occasionally, when I visit
Finland. I don't know yet when I'm going to be in Finland next
time. A somewhat longer term plan is to become QRV from Denmark
on 1296 and maybe also on 2304. I have good visibility to south
and west from my new location, but I need quite a high elevation.
Also some work must be done to find a suitable dish and build up
the installation. I have a theory as to why my 70 cm JT44 skeds
did not succeed. My AF noise level on 70 cm is clearly lower than
on 1296, so I used the MIC input of the soundcard instead of the
LINE input. But there is some kind of "booster" device in the MIC
channel. Maybe it does some compression too that may have ruined
my audio by distorting it excessively. [In setting up F5SE on
JT44, we also used the MIC input and observed some strange
effects. If we turned the audio level up enough to drive the JT44
program in to the proper range, the MIC channel was in over
compression. If we reduced the input to MIC channel's linear
region, there was insufficient level for the WSJT program to
function properly.]
ON4BCB
Walter is new to EME on 23 cm
and looking for some advice -- I have a DL9EBL "type B"
(description in Dubus) cavity for a YL-1050/52, which is giving
me some problems with a Thomson YL-1050. The Thomson tube is 0.2
mm out of maximum specs. The minimum cold resonance frequency is
1335 MHz, I think due to the tube's characteristics. I'm looking
now for a Siemens YL-1050 or 1052 to see if this tube makes any
difference. If you have any ideas, contact me via e-mail. You can
see my status on my Web page at www.qsl.net/on4bcb. [Walter was
at the Prague Conference and may have received some help there.]
OZ4MM
Stig only had a little time for EME this
month -- I was QRV on 13 cm during the post SW and worked ES5PC
in KO38HJ for an initial and new DXCC. He has a very good copy
(549) even though he is running only a 2.6 m dish with linear
pol.
SK0CC
Sven is experimenting with JT44 on
70 cm. I worked on 1 Aug K2UYH for my very first EME JT44 QSO,
on 3 Aug SM2CEW, partial DL4KG, N9AB (solid even heard), nil
OH3MCK (30 W 19 dB ant) and partial KJ7F, on 8 Aug partial KJ7F -
almost finished but Terry had to go to work, and on 10 Aug KJ7F -
sampling of several transmissions did it this time. DL4KG, G4YTL
and EA3DXU are now QRV on JT44 on 70 cm. I have not seeing any
JT44-interest from Japan yet. I would like to try with VK3FMD or
K2TXB and anyone else willing to try JT44 on 70 cm. Based on my
JT44 experience: Do NOT touch the RX knob during the RX 30 sec.
Period. Do your RX adjustment in the TX period.
VE6TA
Grant was on 23 cm during the post SW and added OH2DG,
DL8OBU and N2UO. He is working on a new dish, but doesn't know if
he will get it up before the fall. His new autotrack system is
working very well now.
WA1JOF
WA1JOF
Don's XYL passed away a few weeks ago. [Our condolences
to Don on his loss.] Things are obvious on hold for a while. He
is planning to move QTH and is reported to have bought a new
place in Farmington.
W2UHI
Frank was QRV on 1296 in Aug and
worked during the SW on Saturday 0Z6OL, SM2CEW and N2UO.
Conditions seemed good, but activity was light. On Sunday he was
on late because of a large thunderstorm. After it passed Frank
QSO'd KA0Y, K4QI, OE9ERC and N2IQ with excellent signals. During
the post SW he QSO'd N7AM for initial #160 with a nice signal,
ZS6AXT, SM2CEW, F1ANH, W7BBM, G3LTF, F6ETI, VE6TA and N2UO - all
on random, and heard DL8OBU. Frank and W4OP continue to gather
data on sun noise vs. solar flux. An updated graph of their
results can be found on Frank's web page at:
W2UHI's WEB Page
W5LUA
Al was active on 1296 during the Aug SW and worked N2UO,
G4CCH and K2UYH. On the post SW he was on 13 cm and added ES5PC
(O/O) for initial #50 and later F2TU on SSB.
ZS6AXT
Ivo's Aug report -- I was not QRV on
SW, because of bad weather. I tried the next weekend on 23 cm.
What a surprise, quite reasonable activity and 4 initials!
However, when I started to operate a fault in my TX coax appeared
again! I checked the Superflex and connectors next to the dish,
and all was OK. Then I moved the connector on the 7/8" coax next
to the PA and that was it! This was after ten trips to the top of
my 6 m tower and balancing there with my Bird wattmeter, hi. I
worked on Saturday 10 Aug SM2CEW, F6ETI, F1ANH, G3LTF, N2UO for
initial #181, W2UHI, DL8OBU #182, W7BBM and N7AM #183, and on
Sunday 11 Aug OZ6OL, G4CCH, F6KHM, OH2DG, IK3COJ, F5VHX #184 with
heavy QSB and K0YW. WA6PY was copied quite well, but this was at
the end of my window. Signals were quite good with heavy QSB on
occasions. The real surprise was activity in the non-SW, but it
was perigee!
K2UYH
I made my 1st 70 cm JT44 QSO on 1 Aug at 0900 with ES8X
for initial #654 and DXCC 78. This QSO was the result of a call
from K2TXB who was skedding them on 144 MHz and told me they
were interested in trying JT44 sked on 432. 432 was the only
band on which they had elevation rotation. It is ashamed that
news of this dxpedition was not better publicized in the 70 cm
and up EME community. I am sure they could have made many more
QSOs. I also tried with them on 1296 where they could only
operate on the horizon, but nil was copied either way. I was
active during the SW on 1296 and worked on 4 Aug 1020 G4CCH
(56/55) on SSB, 1112 W5LUA (55/54) on SSB, 1135 VE6TA (559/559),
1153 SM2CEW (559/569), 1216 OH2DG (569/569), 1232 OZ6OL
(559/569) and 1240 OE9ERC (56/57) on SSB. Heard were N2UO and
PA3CSG. I also QSO'd on JT44 on 70 cm on 1 Aug at 1005 SK0CC
(O/O), and tried with OH3MCK and VK3FMD with nil copied at my
end, although both copied me. As the moon was near apogee, we
decided to give the post SW when the moon was near perigee a
try. The results were frustrating. I had a near miss with OH3MCK
who is running 30 W and a single yagi on 432 – see picture in
last month's NL. I copied him full calls and was sending O's,
but he was never able to get full calls from me. Then almost the
same result but reversed with VK3FMD. He was sending Os to me
(which I copied), but I never was able to fully decode his call.
I have very heavy tree blockage in his direction, but could
still hear my echoes. In between my JT44 activity on 70 cm I did
catch on 10 Aug at 1611 SP6JLW (559/549) #655 on random and 1709
RA1LE (559/539). I also heard some random JT44 on 432.024, but
had a clock problem at the time and never decoded the station.
[The JT44 random CQ calling frequency has been moved to
432.044].

different moon tracking programs has not been much of a concern.
At 144 Doppler shift almost need not be considered, but at 10 GHz
and now 24 and 48 GHz a small error can be several kHz, and with
JT44 the RX window is only +/- 600 Hz. F5SE has been working on a
program for improved Doppler calculation. While visiting with
F5SE and F2TU, (as we listened to Philippe's 3 cm moon echoes),
we compared the Doppler shifts predicted by the F5EHN, VK3UM,
WSJT and F5SE's programs. Differences of more than 3 kHz were
found. In some cases the error could be even greater as we did
not search for the worst case. At 1296 the error was about 300
Hz, which is much less but could be a factor on JT44 when added
to errors from other factors. (Remember on JT44 you want to use
the mutual Doppler, not the Doppler of your own echoes). I am now
using a TS2000 directly on 1296 and am finding an error between
the Doppler echo frequency predicted by my moon program (WSJT)
and the echo frequencies observed. I usually keep WSJT
(moon/Doppler data) on the screen of my computer along with
Spectrian (which shows my echo frequency to the Hz). The
difference is usually about 800 to 1000 Hz. I have also observed
a similar effect on 432, but to a much smaller extent (~ 200 Hz).
Have others seen a this phenomena or have an explanation?
FINAL
Because of our travel this past month to the Prague
Conference, this NL is out of phase with the moon. I am afraid
the situation will not improve much this coming month as I am
heading back to Europe on the 23rd for another conference and
will not be back until 4 Oct. I will be in the vicinity of Milan,
Italy the weekend of 28/29 Sept and am always interested in
meeting other EMEers.
There are no skeds with this NL because of its timing. I am also
trying to work out an arrangement to keep the skeds current on
the version of the NL that appears on W6PA0ZN's Web page. Joe,
K1RQG, is concerned about posting direct e-mail skeds in his
Skeds List. He feels that conflicts with regard to time and
frequency could make this task impossible. This is one of the
problems with open skeds. Right now we have little NL skeds
activity. One solution is to run NL skeds on a first come, first
gets the frequency basis. If a conflict is received a
notification could be mailed back that the frequency is already
in us. I suggest that 035, 040, 050, 055, 060, 065 070 and 075
be recommended for skeds with 035 and 040 reserved for NL skeds?
Last month I started shading in yellow parts of the NL that might
be of special importance. I wonder if you find this helpful?
N2UO and I had planned to attend the Microwave Update Conference
in CT, but I just discovered that the date 25/27 Oct is in
conflict with the 1st weekend of the ARRL EME Contest. This is
very disappointing.
Despite comments by some to the contrary, I believe activity has
not decreased, it has just spread out over time and frequency.
If all the activity on 70and 23 cm were combined this would be
clear. Concentrating activity on one SW again would also help,
but may not always be practical. Please keep the reports and
technical info coming. We will be looking for you on the moon
during the coming month.
