14.345, 10 AM ET SATURDAYS, AFTER VARO NET SUNDAYS:
All in all, many regulars seem not to be on the microwave
bands this weekend. The first contest weekend usually yields
more than 50 contacts. So there is hope to make more QSOs
than usually in the second round.
Shigeru located 40 km north of
Tokyo was active 23 cm in the contest. Using a 3 m dish with
100 W at the feed he copied HB9BBD, HB9Q, OE9ERC and OE9XXI
in JA-EU window.
Billwas QRV in Oct on 70 cm for the
ARRL contest and plans to be so again in Nov. He QSO'd DF3RU,
DJ3FI, DJ5NV, DJ6MB, DL9KR, EA3DXU, F2TU, F6KHM, G4RGK,
HA1YA, HB9JAW, HB9Q, JH4JLV, JH6AHB, JL1ZCG, JR9NWC, K1FO,
K2UYH, K4EME, K5GW, K5WXN, K9SLQ, LU7DZ, N9AB, OE5EYM, VK3UM,
VK4AFL and YU1EV. He found good conditions, but with lower
than normal activity in both EU and the US. Initials were:
HB9JAW #306 and LU7DZ #307 and country 46, and YU1EV #308
country 47. Bill thanks YU1EV for staying with him to
complete the QSO. His contest score is 34x20.
Bruce was QRV on 23 cm in Oct with only his driver, as
his PA is apart and awaiting parts. He still had a big signal
and worked many stations in the contest on 1296 including 2
JAs. After the contest, he QSO'd W9IIX for initial #125.
Steve has had very limited time in
2002 to operate and the 1st weekend of the ARRL contest was
no exception. He had 3 other activities during the weekend in
addition to the EME contest. One of which was the annual
Eastern VHF/UHF Conference which also hosted Microwave Update
this year in Enfield, CT, about an hour from Steve's QTH.
During the weekend he spend the days at the conference and
then came home to get a few hours of EME operating at
moonrise. He was also on for moonset on Saturday. On Sunday
moonrise activity was very low so after an hour, a decision
was made to get some sleep and get back on for European
moonset. Initially this plan worked well as a few more
stations were QSO'd. The plan went awry when ac power was
lost for several hours. Just as Murphy would have it, ac
power came back on 5 minutes before moonset. His 1st weekend
contest totals were 45x24 with only about 10 hours of
operating time. 3 initials were QSO'd with OK1DIG, HB9JAW and
DL7UDA. This brings his 70 cm total up to #606. Steve hopes
to be able to put in more hours in Nov, but is keeping his
fingers crossed that WX will be good as the northeast US had
a very cold Oct this year.
Cowlesis back in operation on 432
-- I had to rebuild most of the electronics in my station due
to a lightning hit last April. The station now consists of a
FT-847 exciter, TE Systems amp driving a Lunar Link LA-70B PA
~ 1.5 KW into 8 x 33 el FO yagis. The preamp is a Cavity Type
using a HEMT. Recently picked up an old Scientific-Atlanta
dish positioner (turn-table type). I think this should make a
fine azimuth control for my 20' dish. It will handle a
Maximum axial load of 10,000 Lbs! I have a computer on order,
XP-2000 type that should be fast enough to run the EME
version of JT-44 software. I should have it on a couple of
Jay was very busy in Oct. He hosted
VK3UM in a post Prague visit to the USA on his way home. Jay
was QRV on 23 cm just about every weekend and QSO'd SM2CEW
and G4CCH, W9IIX (529) for Doug's 1st 23 cm EME QSO. Jay had
excellent results in the contest, but will not release his
score except to report he had 26 multipliers on 1296.
Dan found conditions very good on 70 cm during the
contest weekend. He worked 22x? with several got a ways.
SP???LW called for about 30 minutes. [Probably SP6JLW]. Dan
says it seems as though the EU stations got on later.
Randy ended the 1st contest weekend with
a score 16x12. He was a bit under the WX health wise but
still had lots of fun and received many FB reports.
Gareth in Hawaii is an EME
newbie -- EME has always interested me, but living in a
townhouse puts limits on what antennas I can erect. Anyway,
during the first weekend of the EME contest, I borrowed my
boss' 19 el 432 Cushcraft yagi in hopes of hearing just 1 big
gun during the contest. I didn't hear anything that night,
but learned a lot in the process. Right now, all I want to do
is LISTEN. Transmitting can come later. My present setup (for
satellite) is an 11' mast with a 9 el 435 quagi and a 4 el 2
m yagi. I took down the 2 m yagi and put the 19 el yagi up in
its place. My rig is a Yaesu FT-736. I now understand that I
should have a preamp at the antenna with at least a 0.5 dB
NF. I am using Ultralink feedline from antenna to rig, about
40'. I was told this should be changed to LDF4-50 at the
least. I was also told that the preamp should be very close
to the antenna - [At the antenna feed]. Any advice would
greatly be appreciated. FYI I chose 432 EME because it's
easier to manage a 70 cm long yagi at the townhouse as
opposed to a 144 boomer.
Steve is just about ready to go on 432
EME. He has completed his second EME array (4 x 21 el yagis)
for 432 MHz and have some new electronics purchased from
K2DH. Steve reports his sun noise measurements seem
acceptable [? dB], but that his moon noise test failed. [Moon
noise is very small (tenths) on 70 cm with even big arrays
and requires special equipment to detect.] During the Oct
contest weekend he heard his 1st moon signals including N9AB,
F6KHM, K5GW and DL9KR – very loud.
Thorton appears to have cured his difficulties on 1296
although he did report some noise problems from his PA tube
during receive. He ended the 1st part of the contest with
28x?. He says he did not much luck during his western window.
Thorton's tel is (352-625-8744).
Anders tried to be QRV on 23 cm from
LA for the 1st part of the ARRL EME Contest, but had problems
with his VK3UM tracking system – see the For Sale section. He
now is trying to be operational during the 2nd leg from EA8.
Marcwrites -- I was not active
during the first leg of the contest because I decided to
attend the Microwave Update Conference in CT. The conference
was great, very well organized by the NE News Group, with
good presentations and an excellent flea market. I didn't
meet too many moonbouncers as most of them were operating the
contest, though K1FO, VE4MA, W7CS and some others showed up.
I also met Matt, KB2VC, who has almost finished a 10' dish
for portable EME. The dish is ingeniously mounted on a
trailer. He has equipment for 3.4 GHz EME, but I suggested he
also put some effort towards 10 GHz EME as his dish surface
is for Ku band TVRO. Right now I am working on a 2 x GI7B
amplifier for 23 cm. The power supply is done, and right know
I am busy with the cavities and couplers. So for the time
being I am back to QRP operation using my driver (2 x 2C39),
which puts out about 90 W at the feed of my 10' dish. In any
case, I hope to work a bunch of stations during the contest
Jukka (OH6DD reports on his contest
results -– The contest weekend was very windy in Finland, but
we could operate without problems. Activity was low due to
the big storm in south/central Eur. We scored 62x31, which is
much below normal. Unfortunately EME contest coincides again
this year with CQWW. Instead of a 2nd leg of the EME-contest,
I will join our HF-contest team OH2U for an effort from EA8.
I hope Matti's station will be activated by someone else
during the 2nd leg. We QSO'd on Saturday 26 Oct UA3PTW

Franta sends his results for the first
leg of the ARRL EME Contest -- I had bad WX with strong winds
on Saturday and rain on Sunday. On 1296 I worked 16 stations
with initials from KU4F, N7AM, K5GW, K9BCT and W7BBM to bring
to #100. Signals from NA were very good and provided many new
stations. 2.3 GHz had very poor activity and I worked only
OZ4MM (559/549) and F2TU (549/549). I missed the window for
ES5PC. I have improved my rig on 3 cm EME. I have a waveguide
TR switch and a new 0.6 dB NF preamp that gives 2.1 dB of
moon noise, but I still have only 12 W on TX. I couldn't
operate 10 GHz on Saturday because of very strong winds. I
was QRV on Sunday from 0600 to 0800, but worked only OK1UWA
(559/O). I CWNR'd I4TTZ and I5PPE and heard F6KSX and F2TU. I
stopped operation after rain began and the signal levels went
Johan is planning to put 3B8 on 432
EME during a dxpedition in March. It will be 2 weeks stay
booked from the end of Feb thru the beginning of March. Johan
has ordered 4 x 25 el 25JXX70 yagis for 70 cm, has an LNA
coming and is getting a GS35 cavity. He will use TS2000X and
will have a laptop with JT44 as well. Any help will be
Stig had a conflict with family
activities, and thus very little time for the contest in Oct
-- I decided to use my limited time on 13 cm. I found only 3
stations around in the few hours I was on. I hope for better
activity on 13 cm in next run. I have increased my power at
13 cm to around 60 ~ 75 W at the feed of my 10 m dish.
Hans' report for the first leg of the contest -- The
storm was not so strong here in Copenhagen, so I was able to
operate from Saturday morning to moonset, although at about 3
in the morning the dish's dancing in the moonlight had me
very worried! I QRT'd but was back on only a short time
later. I worked HB9BBD, JA6AHB, IK2MBB, F2TU, OE9ERC, G4CCH,
OK1CA, N2IQ, OE9XXI, K9BCT, K5JL, W2UHI, K0YW, KA0Y, KU4F,
W7BBM, HB9Q, VE6TA, N7AM, W1ZX, DL4MUP, IK3COJ, JA8ERE,
DK0ZAB, JA6CZD, WA6PY, OH2AXH, K2UYH, W5LUA, SM2CEW, I0UGB,
K5GW, W7SZ, G3LTF and F6ETI for 35 QSOs.
Carsten reports that his project to
get back on EME in "big way" is progressing very well. The
elevation system for the new 8 m dish is now complete
(hydraulic). The next task is the AZ drive, which is being
welded. It will consist of a large gearbox and a 1:4 chain
drive to the center of the rotating tower. He has 2 absolute
digital encoders for the position readout. The box for the
feed horn is ready as are the feed tubes. Carsten only needs
to build a suitable feedhorn and hopes to be ready some time
Paul was QRV in the
contest on 6 cm EME. He used on 5.7 GHz a 20 W PA and a 3 m
dish with a linear vertical pol feed. Paul is receiving about
0.5 dB of moon noise. He is interested in skeds and can be
reached by e-mail or GSM at +386 41 751 297.
Peter has a new 1296 [?] PA and a much improved
tracking system. These efforts apparently paid off in Oct. On
432 he added initials with OK1DIG (his initial EME QSO),
SP6OPN and DL5LF with a single yagi. He also worked DK3BU on
a small 4 yagi tropo array. Peter could not operate much of
the contest due to high winds, but after the contest he added
more initials on 70 cm with SM5IOT and DL7UDA. He was also
active on 23 cm through much of Oct and QSO'd W2UHI, K5JL and
Grant sent the following note on
his activity during the contest – I tried to get on 222 for
WA4NJP and WD5AGO, but the high power relay I use on that
band was stranded on the roof after an earlier 6 m EME
effort. Unfortunately 2" to 3" of ice and snow on a steeply
pitched roof made it a bit hazardous to retrieve. I ended up
spending the weekend on 23 cm where conditions seemed good
despite the lack of many EME regulars from Eur. Murphy struck
by causing my auto-track system to malfunction on rising
moon, and my 4 tube amp decided that it wasn't going to
perform. I switched relays on the tracking board to enable
the system to would work with a rising moon, and put off work
on the resulting decreasing elevation problem until later.
The amp was a little bit harder to track down. I discovered
that the tuning capacitor for the anode section of the cavity
had a poor solder connection and was creating a lot of heat,
and as a result the amp had poor efficiency. I re-soldered
the connection and reassembled the cavity to bring it back to
450 W output. This was just in time for the second pass. I
worked 27 x 21. Initials on 23 cm were N7AM, W1ZX, KU4F,
K9BCT, W7BBM, and I0UGB. Kudo's go to WA6PY for having an
outstanding signal with his small dish, as well as all the
outstanding regulars for giving us signals so loud that my
ears hurt - OE9XXI, HB9Q, K5JL, KA0Y, OE9ERC, K5GW, and of
course HB9BBD. I would hate to have these fellows power bill
after the contest. I am not sure what band I will be on next
month, as it will depend on getting the high power relay down
from the roof. If the weather gods cooperate I will try and
be on 432 next month for at least one pass.
Doug reports tough WX conditions in VK3. During the
1st weekend he QSO'd 27 stations on 432. He only heard 3 JAs
and reports that VK5MC was going to try to be on. Doug says
it is great to be home, but that he had a great time when on
holiday in Eur and the USA. Doug will be QRV on 23 cm soon –
Willie reports the W4TJ operated his station during the
EME contest on 1296. They worked 19 stations the 1st night,
but had computer problems the 2nd night. Signals were quite
good, but their moon window limited to elevations >40 and <69
Richard, WA2IKL reports on the SETI
EME beacon -- As promised, the W2ETI beacon is back on. One
reason for the shut down in August was that the power amp was
slowly losing output. It was my intention to do some
troubleshooting. I never got a chance, but I figured better
a little low rather than none. Surprisingly, when the beacon
came back up the power had returned to normal. Now I have to
figure out whether something just needed a "rest" or what.
It's certainly possible that the actual problem was in the
measurement, since I have three different ways of measuring
power and they disagree with each other by a couple of dB.
This is not the case with frequency. The beacon should be
spot on 1296 +/- 2 Hz at the most, and more likely -1/+0.
I've verified this with two Rb standards, two GPS standards,
and a completely separate quartz oven oscillator, which is
about 6 Hz off at 1296.
Frank worked on 23 cm 24x19 in the 1st leg of the
contest. Activity was slower on the 2nd night and he only
added DF4PV and HA5SHF – both for new multipliers. He missed
W5LUA on Saturday and never heard him on Sunday. After the
contest Frank did a bit of experimenting with his Scaler ring
and moved it forward about an inch. He feels that he has
increased his signal to noise, and was able to work K5JL at
the S-3 level with Jay running only 2 W!
Joel writes -- I have recently
relocated and am interested in moving from satellites to EME
- specifically, 432 EME and eventually 1296 EME. I currently
have the Yaesu FT-847 and G-5400B rotor and controller. At
this time, I have no PA or preamp and want to just experiment
with JT44. I'm also planning on building the K1FO 432
antennas described in the ARRL Antenna Handbook. I am
interested in locating web sites with basic information on
[Try EME Stations]
Larry was unable to be QRV the 1st night, but was
active on Sunday. With his 12' dish and 450 W on 1296 worked
Doug (EN61dr) is now QRV on 1296 EME
with a 10' dish, VE4MA feed (W5LBT tracking) and 100 W from
water-cooled 2 x 2C39 PA. He made his initial contact with
K5JL in Sept. In Oct Doug worked during the contest HB9BBD,
G4CHH, K5JL, KA0Y, W1ZX, 0E9ERC, OE9XXI, K5GW and N2IQ for a
total of 9. He CWNR HB9Q and OH2AXH many times. On the post
contest weekend he added K2UYH, K0YW and G3LTF to bring him
to initial #12. Doug has not yet heard his own echoes, but
will eventually solve this problem with a larger PA. His
address is (Douglas Johnson, 4421 W. 87th St, Hometown, IL
60456). Tel is 708-423-0605.
Paul reports on the first part
of the contest – I QSO'd in the first part of the contest on
1296 HB9BBD, HB9Q, N2IQ, W2UHI, G4CCH, W1ZX, K5JL, K5GW,
K0YW, W5LUA, KA0Y, N7AM, K2UYH, G3LTF, OE9XXI, KU4F, VE6TA,
OH2AXH, OZ6OL, SM2CEW, OE9ERC, IK2MMB, F2TU, W7SZ and IOUGB
for 25 stations. F6ETI and DL4MUP were got away. A few
station called on my CQs, but I need a longer time to
recognize call letters with my 8' dish. Please do not give up
as long as I respond with QRZ? This means that I can copy,
but I need more time. For many hours I heard a modulated
signal at about 1296.006-7. I wonder if anybody else heard
that? I heard two marginal signals with my dual dipole feed
on 432, but I did not concentrate on recognizing the
callsigns. I plan to be on 13 cm the first night in Nov and
on 23 cm on the second night. I will still monitor 432, and
if I will hear any stations I will try to QSO.
Tommy writes – I finally got
settled in the new location about 7 mi SE of the old house,
same grid EM26. I am not supposed to have up any antennas in
the air, which is not that big a problem. I'll just put down
the EME array when not operating – Hi, Hi. I was on 222 MHz
in Oct and worked WA4NJP. I want to have a system going on
5.7 GHz in Nov, and am not sure what other bands I will be on
- possibly 222 MHz again and/or 432 MHz. 1296 is not out of
the question either. [Congrats to Tommy for receiving the
Teacher of the year award from the ARRL – see Oct QST!]
Szigy was QRV on 70 cm during
the contest -- During the 1st leg of the ARRL EME Contest I
found conditions variable and not too many stations QRV. I
made 9 QSOs including K1FO and JL1ZCG, who had the loudest
signal I have ever heard on 70 cm EME and that for several
hours. I CWNR N9AB and K5GW after his QSO with KL7HFQ. No
other stateside stations were heard. This was my 13th
participation in row in the annual ARRL EME Contest using the
same old fashion but still in good shape rig and antenna. If
all goes okay I will be on 70 cm again in the second leg.
Brent is working on 1296 EME --
I am only RX at the moment and having some problems with only
weak signals being heard so far. The system is a 6 m dish
with an IMU feed on a modified Seacat missle launcher for
rotation with an DB6NT 0.4 dB NF preamp. I am seeing 15 dB of
sun noise and 0.75 dB from Sag A, but has only heard 2
unidentified weak signals off the moon so far. [Are you sure
you are using the correct circular polarization?] I need to
do some more work by Nov. I will be listening again.
I operated on both nights of the contest, 1st on 432
for several hours and then switched to 1296. Activity on 70
cm seemed much lower than in past contests. Activity on 1296
was better than on 432, but not up to par. Signals were much
stronger there too, but this may be the result of my
increasing noise problems on 70 cm. There was some sort of
wideband pulsed noise that came on periodically, and of
course usually at just the right (wrong!) time to mess up
copy of someone's call. I don't think I had difficulty
copying calls of any 1296 signal until my VK/JA window.
There I had about 3/4 tree blockage of the dish and had to
QRZ everyone. I worked two JAs on 1296, then switched to 432
and worked VK3UM - TNX Doug. I also heard several JAs there,
but could not get their attention. I kept calling CQ down to
about 10 degrees where my echoes disappeared, but not one
reply. WA2ILK President of the SETI League visited on
Saturday night to help with operation and to get a better
feel for EME operation. I think Richard was impressed by the
EME signals. We QSO'd on 26 Oct on 432 at 0348 DF3RU

weekend were 18x15 on 432 and 28x17 on 1296. I now have the
newest version of JT44 installed. The Doppler frequencies of
the new JT44 (V3.0) are quite close. I tried the echo mode
again. Using the TS2000X barefoot, I clearly observed echoes
with .5 W into the feedline! I also tried the echo mode on
70 cm with my tropo antenna (modest preamp in the shack). I
was able to see my echoes, but needed at least 500 W. This
is probably an indicator of my noise problems. The weekend
after the contest, K1JT visited to see JT44 in operation. I
had a JT44 sked arranged for 2 Nov with DL7UDA on 70 cm.
Unfortunately Dietmar had equipment problems and was unable
to TX on JT44, although he copied my signals. I was able to
demonstrate the echo mode on 432 and 1296. The day before on
1 Nov, I worked on 23 cm at 1300 W9IIX (5549/549) #208 and
had a 3-way SSB QSO at 1329 K0YW (57/57) and G3LTF (56/55).

N2IQ is getting 21 dB of sun noise on 1296 with his new 28'
dish. Mark was active on only 23 cm in Oct and worked 24. He
expects to be QRV for only the 1st contest weekend.
WA9FWD was not on for the Oct contest weekend as at Microwave
G3IRQ hopes be QRV on 23 cm EME in the near future. Peter has
solid state 150 W PA and TVRO. He needs to build a feed.
9H1BN has a 3 m dish for use on 1296 assembled and on a
mount. He still needs a feed and will try to be QRV for Nov,
but makes no promise. He reports that 9H1ES and has problems
K5GW now QRV on 1296 with a new 22'dish and 1.5 kW.
VE3AX is making progress on mounting his 28' dish.
AA5C was active on 3 cm in the contest, but had nil results
with DJ5MN. He is working on new preamp. His e-mail address
F6KHM is now getting their best echoes ever on 70 cm with
their 34' dish and new TH-293 cool 2.5 kW PA. They are using
a dual dipole feed wired for circular pol on TX but V or H
for RX. WX limited contest operating time to only 2 hours on
Saturday and 15 QSOs.
W7MEM was active on 70 cm during the contest, but had to cut
operation short when his 432 module died.
WB0GGM was QRV on 70 cm in Oct and hopes to add 23 cm by next
G4RGK had very high winds during the contest weekend. Dave
was forced to go QRT only 20 minutes into contest. He got
back on for a couple hours on Saturday morning and worked a
few stations on 70 cm. Dave was able to QRV for a couple more
hours on Sunday and ended with 8 contacts. He also notes a
problem with green Algae on his antenna elements. Dave's moon
window is limited to >30 deg elevations.
F5VHX did not get on due to the high winds.
NA4N will not be for the contest this year. Family issues
kept Greg from EME projects. Both parents passed away. [Our
sympathies to Greg and family.]
DK3WG because of the high winds and bad WX was only active on
70 cm for short time during the contest and made no contacts.
DL9KR was able to operate a total of 4.5 hours during the
contest. He was on only 55 minutes before 70 mph gusts forced
him to tie down his antenna. Fortunately there was no damage.
He made only 9 contacts the 1st night and end with a score of
40x28. This is 40% of Jan's usual total.
PA3CSG reports only moderate winds at his QTH on Saturday,
but still too windy for 3 cm operation. Geert was on 70 cm
for a bit of time. WX was much worse the 2nd night and he was
glad to just have his dish survive. After the contest he
worked PA4FP on 70 cm for a new one.
W2DRZ did not make it on 23 cm in Oct, but hopes to on in
F6CGJ was not on due to the bad WX.
F5PAU was not either.
GM0ONN has been traveling a lot this year, but hopes to be
back on 1296 in Nov.
DJ5NV was on during storm, but could not be QRV the last 5
hours and ended with a score of 41x26. He called K1FO with 10
W and Steve sent QRZ. He will be QRV again in Nov.

is selling a 23 cm
cavity for 2x 2C39 tubes. The unit is a complete RF module
made by EME Karl Müller (The producer of the HF400 relay).
With 6 W input you get 150 W out. The unit has very effective
cooling of the whole tube, and runs a silent EBM radial
blower. It can be easily modified for water-cooling, if you
need more power. It comes complete with a new matched pair of
2C39BA from Siemens, original bias-circuit board (1 spare),
all silver-plated and in excellent condition. I also have the
original power supply from EME Müller, including the
transformer with 3 taps on the HV-secondary, heating, small-
voltages, ceramic-switch to change the anode voltage, and dc
circuit board with current and voltage metering. He is asking
300 Euros for the RF unit, and 150 Euros for the power
supply. Selling all together is preferred, so contact Tom for
a combined price. He is looking for an ICOM IC 475E/H for the
DL0AO 70 cm EME station.

K1JT has released a new version of JT44 with an
echo mode that should be of interest to EMEers whether you
intend to use JT44 for EME contacts or not. The echo mode
allows you to evaluate the EME capabilities of your system,
even when you have too small a station to hear your own
echoes. For larger stations, it allows you to investigate the
limits of your system. I was able to easily detect echoes
with less than 0.5 W on 1296 and observe echoes with my tropo
system. Joe, K1JT has sent in the following in formation on
this mode -- The preferred procedure at high frequencies in
EME Echo mode is to set your receiver's RIT to something
close to the computed Doppler shift and enter that offset
into the on-screen RIT box. A new (as yet unreleased) version
of WSJT makes this process somewhat smoother and introduces
other significant improvements as well. This version is not
yet ready for open release, but will be available soon. In
the EME mode the Doppler value listed on the JT44 screen is
now the two-way Doppler from your own grid to the location
displayed in the Grid box next to the "To Radio" entry. The
Doppler value listed on the Echo mode screen is the number
for your own echo. The WSJT Doppler values differ from those
of GM4JJJ's MoonSked (for example) by around 10 Hz at 144
MHz. I have not yet had the time to track down which software
is more nearly correct, and I don't have a reliable figure
for the accuracy of the WSJT calculation. [I have found the
new version is in close agreement with echoes observed on
1296 (< 50 Hz difference).] When observing my own echoes on 2
m, I get values of DF ranging from about -16 Hz at moonrise
to +4 Hz at moonset. These numbers are stable and
reproducible (at least over several weeks). Surprisingly,
though, I've discovered that running the program on a
different computer can change the observed DF for echoes by
nearly 10 Hz, even though the number is stable on both
machines. I don't know what this could be other than some
inaccuracies in the A/D and/or D/A sampling rates of the

G3SEK has sent in the 2003 Lunar Calendar. Ian notes that the
choices for the early months are easy. The dates for the
DUBUS/REF Contest are already fixed (15/16 March for 432 &
2.3-5.7 GHz and 12/13 April for 144, 1296 and 10 GHz).
Through the summer we are forced to use low declination. In
the fall it gets better again, so the decisions for the ARRL
contest should be easy. Proposed dates are 18/19 Oct and
15/16 Nov. We will print the full 2003 Lunar Calendar in the
