. You can arrange skeds by
contacting him directly by e-mail. Daniel’s address is (D.
Oliver, 121 Lomas de zamora, 1832 Buenos Aires, Argentina.)
His grid is GF05tf. The station is now a 6 m dish and 70 W
PA. Under construction is a 600 W KB2AH cavity PA and a 300 W
PA of LU6DW design. The Sun noise is 20dB at a 200 solar flux
(KB2AH preamplifier). Tracking is with an azimuth camera, and
an 2nd camera for elevation is near ready.
Hoppy writes -- Conditions on 1296 were quite good
during the July SW. All signals were good copy with lots of
activity, and all my equipment worked great! I QSO'd on 10
July G4DZU (partial), ON5RR, W2UHI, OZ6OL, K5JL, OZ4MM,
N2IQU, GW3XYW, VE1ALQ, W6HD (big signal) and VE6TA, and on 11
July PA3CSG, KB2AH, KD4LT, OZ4MM, K5JL, ZS6AXT, W2UHI,
OE9ERC, VE6TA, GW3XYW, G3LTF, EA6ADW and W1ZX for initial
#136. Others heard were W6HD, VE1ALQ, and LU8EDR on SSB
Rick was active on 13 cm during the July SW. He worked
IK2RTI and W5LUA and heard OK1KIR to whom he sent a report,
but received nil in reply. Rick missed WA8WZG.
Pertti is now QRV on 5.76 GHz with a 6.4 m .3 f/d
dish and V/H feed. He has a 35 W SSPA at the feed and a HB
NE32584 LNA for RX.
Stig has finished his holiday and is now on active
duty again -- On 10 July I spend a little time on 432. I
worked on random DL1YMK (549/559), G3HUL (449/449), KA0RYT
(549/569), RW1AW (549/569) for initial #183 and IK5QLO
(429/449) - Andrea is doing a FB job with 2 yagis. As I found
activity low on 432, I switched to 1296. I worked on 10 July
N6BQ (559/559), W2UHI (559/569), ON5RR (449/549) and W6HD
(579/569), and on 11 July G4DZU (549/559), HA5SHF (429/559),
KD4LT (579/569), PA3CSG (579/579), KB2AH (579/579), N6BQ
(559/569), ZS6AXT (559/579), W6HD (579/569), OE9ERC
(579/589), G3LTF (559/569), K5JL (589/579) and finally W1ZX
(569/559) for initial #150. I found condx very good and
activity much better than on 432!
Hans was active on both 432 and 1296 in June, and can
now switch between bands in a few seconds. On 70 cm he worked
on 18 June DL9NDD (559/559) and OE3JPC (O/O), on 19 June
OK1KIR (O/O), DF3RU (559/549), OE2UKL/p (559/539). [Any info
on this station?], EA3DXU (O/O), and W7HAH (O/O) sweeping
the tops of trees, and on 20 June KD4LT (559/449) and DF3RU
(559/549). His 70 cm Sun noise was about 13.5 ~ 14 dB. On 23
cm Hans contacted on 12 June W2UHI (549/539), on 18 June
HB9BBD (579/559), VE1ALQ (559/439), KB2AH (579/549) and K5JL
(569/549), and 20 June HB9SV (579/559), OE5EYM (559/529),
HB9BBD (55/55) on SSB, F1ANH (569/549) and ZS6AXT (549/549).
Hans now has 130 W at his feed with 1.8 dB of cable loss. On
RX he is getting 18.3 dB of Sun noise with a .4 dB NF preamp
and measures side lobes at 21 dB. [Hans also asks about the
dish position readout system I reported in the June-2 NL.
Originally I used a tape measure wrapped around a large ring
(hub) on the dish mount. A television camera and monitor
displayed the inches from the tape and I converted these to
degs using a conversion a table. Tom, KB2AH made up a large
disk with degrees precisely scribed on it. I can now read out
azimuth to about a tenth of a deg. A similar arrangement
could be used for elevation.]
Alex's mailing address is (Alexander Boreyscha, Pr.
Engelsa d. 143/1 KW. 12, St. Petersburg 194358.) His grid is
KP50eb. His tel is 812-5999537. Alex is running 12 x 15 el BV
yagis and a 1500 W PA.
Barry found conditions on 5.7 GHz strange. He QSO'd
OE9ERC (569) and CT1DMK, but signals were raspy. Later he
added OH2AXH (559/449) for initial #13. Barry is working on
24 GHz EME.
Grant was QRV during the July SW on 1296 and found
conditions very good. -- I was only on for a short period due
to working the nightshift. I managed to work the following:
GW3XYW (449/339) for a new one and a new DXCC location, W2UHI
(549/539), N6BQ (449/329), ON5RR (O/O) another initial from
DO33 and W6HD (559/549) - big signal. I am running 275 W to a
5 m dish.
Willie finally made it on 23 cm during the June SW
after a number of years construction. He QSO'd at 19 June at
2108 KB2AH (579/559) for initial #1, 2116 K5JL (579/439) #2,
2153 W2UHI (339/O) #3 and 2218 W6HD (459/459) #4. In July he
still had some Moon tracking problems, but hopes to have a
solution soon. Willie worked on 10 July at 1505 W5LUA
(O/539), and on 11 July at 1400 DJ9YW (559/559), 1445 EA6ADW
(559/559), 1505 OZ4MM (559/559), 1535 N6BQ (559/559), 1600

W7CNK on 5.7 GHz, W1ZX on 1296 EME for an initial, and
WA8WZG, NU7Z and W4HHK on 2300. Al is working on a TH-327 amp
for 23 cm.
Joel, ARRL Vice President writes -- The dates for the
1999 ARRL International EME Competition will be 30/31 Oct and
27/28 Nov. As always, the ARRL sought as much input as
possible concerning this year’s dates. Discussions were
conducted on the 20 m EME nets as well as the Moon-Net
reflector. Several concerns were expressed regarding weather
during the Nov weekend and contest conflicts during the Oct
weekends. All of these concerns were taken seriously into
consideration, however no real consensus was achieved as to
the most preferred dates. Lionel, VE7BQH, assisted by
conducting a survey of EME operators on all bands inquiring
which dates you wanted. The results of that survey have
previously been reported, and as one can clearly see, no date
was a clear preference. This left us with the difficulty of
selecting a set of weekends that would not be attractive to a
large group, regardless of which weekends were selected. If
these dates were not your choice, please understand the
situation and I want everyone to know that we will again look
at the dates in the same manner for the year 2000 in an
effort to select the best possible weekend combination to
permit maximum participation in the competition. I want to
thank all of you for your support of EME activity, and
especially thank Lionel and Joe, K1RQG, for their help in
disseminating information leading up to this decision. I also
want to thank Lionel for conducting the survey and presenting
the results to everyone.
Chuck is excited about being back on 5.7 GHz EME. He
had an excellent QSO with VE1ALQ (559/539) and later worked
VE4MA, W5LUA, OE9ERC and OK1KIR. Another station called just
prior to OK1KIR, but he couldn't identify him. He was also
called by CT1DMK. He is measuring 19.8 dB of Sun noise and
2.2 dB of Moon noise on 6 GHz. On 70 cm Chuck worked VK4AFL.
Tom is ready to go on 10 GHz EME. During July he was
active on 13 cm. He worked W5LUA
Ivo reports -- On Saturday 10 July there was no
activity here, I was busy. On Sunday 11 July I worked on 23
cm GW3XYW, EA6ADW, OE9ERC, KD4LT, G4DZU, W2UHI, PA3CSG,
OZ4MM, N6BQ, W6HD and VE6TA
I was on 70 cm the 1st day of the SW. I made it on
late, around 1400 because of problems with the voltage to my
preamp. It was fine when I checking things out on Monday, but
was not working when I wanted to operate! I think I finally
found the cause of this problem, which has been a recurring
scenario, and hopefully have fixed it permanently. The break
in the wires was not where I thought it was. Activity was
light, especially from NA, but I still made 2 initials. I
worked at 1359 SM3AKW (559/549), 1413 DL3NDD (559/569), 1433
G3HUL (549/449), 1440 DL1YMK (559/559), 1525 AL7OB (O/O) a FB
signal for initial #617, 1600 AL7OB (559/559) again, 1925
JA5OVU (559/559), 1950 JA6AHB (O/O) - dish well into the
trees and 2015 K1FO (449/569). I was unable to be on 1296 the
next day because of a conflict with a wedding and then leaving for a week's vacation.

The following are the results of the informal survey
taken by Lionel, VE7BQH on preferred dates for the 1999 ARRL
EME Contest. 48 people answered Lionel’s Survey. 23 favored
2/3 and 30/31 Oct, 24 favored 30/31 Oct and 27/28 Nov, and 1
for Either date. Opinion was pretty evenly split and did not
appear to depend on geographic area. Lionel did not provide
information on the bands operated by the respondents, but I
doubt that this was a factor. The official dates have now
been set and are 30/31 Oct and 27/28 Nov – see W5ZN’s Report.
There was a question on the 20 m net as to why the July SW
was schedules a week after perigee. This was because the Moon
was just about in sync with the Sun on the perigee weekend.
Please keep the reports and technical info coming. I hope to
CU some of you at the EME Symposium in Rochester on 21-22
Aug, and off the Moon. During the SW.

Notes on TH-327 Cavity by K5JL (part 2) or Hello You Lucky
Owner's of the TH-327 Cavity:
This is just an up-date on the operation of the TH-327.
After all of the modifications that I have earlier described
are made the cavity should purr like a kitten. I did have to
remove the muffin pan fan and add a blower to direct air on
the lower part of the cavity. This cooled down the input
section of the cavity so that after a long cq or transmission
- it is still cool to touch. I now notice no thermal drift
on the input.
Operation: I was not getting the power out of the
cavity that I though, as I had no good high power slug for
1296. I was showing 1500 watts out on my 2.5kw slug (436-12
200 to 500 MHz). Darrell sent me his 1296 slug and as was
expected my 2.5kw 432 slug was reading 2 times the actual
power. My 1500 watts out were only 750 watts. No problem
Jose - goose the drive up a bit and bam - was pinning my 2.5
kW slug (at least 1250 watts out) Goose it a bit more and I
was pounding the pin (showing excess of 1500 watts.) The
more drive I gave it - the harder I hit the pin. With only
type N connectors I decided that I would run it so I just
bumped the pin. (Probably 1300 to 1400 watts out) I am sure
with about 200 watts of drive it would easily make 2 kW out.
I took the 25 mm disc on the output probe off and
installed one that was 15 mm. The max power I could get with
the smaller disc was only 600 watts and that was when it was
very closely coupled. It acted like I was getting true
capacity coupling from the cavity, but power was low. I re-
installed the 25mm slug and came way out (as far as I could
go) and at that point the power just seemed to jump out. I
believe that the output probe at this position is inductive.
(Thus getting inductive coupling-thus getting inductive
coupling with the 25mm probe instead of capacitive coupling)
This would appear to be true if it were not placed at the
exact 1/4 wave point to insure capacitive output for the
probe. At any rate who cares, as it works. Plate tuning is
about half way in and very sharp.
As more drive was added I noticed that the plate,
screen, and grid current did not increase as I had expected
it to. In fact the whole amp cooled down.
It is running much cooler at 1.5kw than it was at 750 watts.
Plate voltage is 3 kV
Screen voltage is 480 volts
Grid voltage is 78 volts
Heaters 5.8 volts at 34 amps
With 120 watts drive and no indicated VSWR on input:
Plate current is 1.1 amps
Screen current 30 ma
Grid current 10 ma
Power out 1.3 kW
Good Luck and let me know how you make. By the way be
sure to change the anode by-pass. I would not consider using
anything but Ultem (forget the Teflon.)
