432 MHZ AND ABOVE NEWSLETTERS.
Sept offered a good warm up for the coming ARRL EME Contest.
The ARI Contest also helped to stir things up, but seemed to have generated
less interest than last year. Although there are some mixed reports,
conditions and activity were generally reported to be good on both 70
and 23 cm. There was also considerable activity on the higher bands.
The 1st 10 GHz QSO was made from Russia by RW3PB with WB5LUA. On 432 look
for LU4HO, who is reported to be coming on for the ARRL Contest.
Luis is getting ready for the contest -- I left the 70 cm feed
installed for a long period, and tried to get the best out of my dish.
This band is now much more attractive then when I was running yagis.
Since my last report I've worked on 432 DK3FB (O/M), JA9BOH (O/M), W7QX
(O/O), G3LTF (439/439), SM2CEW (449/449), K2UYH (449/549), G4ERG (O/O),
W6IMC (O/O), KB3PD (O/O), K1FO (559/549), VE1ALQ (559/549), KA0RYT (O/O),
SM3AKW (O/O), OZ4MM (559/549), G3SEK (449/339), UR5LX (O/O), I2COR (O/O)
and OE5JFL (579/449). Heard were DL6WU, OK1KIR and DL6NAA and CWNR were
UT5EC, ON4KNG (559) - who I called for 1 hour, DL9NDD, DL6NAA and HA1YA
(549). During the 1st contest weekend, I will start on 10 GHz during the
US window and will be on 70 cm the rest of the time. If things get
difficult on 70 cm, I may go to 23 cm as well. I have no window at
sunrise or set, so I will be on 2 m at these times.
Klaus is now QRV on 70 cm EME from JN59cp with 4 x 23 el FLEXA yagis,
a 500 w TH308 PA and 0.4 dB NF SSB Electronics LNA. He is interested in
skeds and can be reached via e-mail at:
Gerald reports via e-mail for the 1st time -- In Sept I found
conditions to be quite poor on 70 cm. Activity was low in spite of the
Italian EME Contest. I worked the following station: on 19 Sept OK1KIR
(O/O) for initial #27 and JA5OVU (549/449), on 20 Sept DL6NAA (O/O) #28,
JA5OVU (549/549) and DK3WG (O/O), on 21 Sept OE5JFL (549/449), OZ4MM (O/O)
and I2COR (O/O) #29, and on 27 Sept (just before my daughter's birthday
party) K1FO (549/439) and N2IQU (539/539) #30. Heard were PA2CHR, ON4KNG,
ON5OF and UR5LX. Nil on sked with 7M2PDT. I heard no NA stations.
Were they active? [You may not have stayed on late enough.] The rig is still
a TS-850 + homemade transverter (NF 0.5 dB) and 500 w PA. The Antennna is 4
x 23 el BV yagis. During the 1st part of the ARRL Contest, I will be on only
the 2nd day, as I will just be coming back from my vacation.
Guenter sends 70 cm news -- I haven't been very active lately, but
found condx good on 20 Sept and made a few QSOs. I worked at 0420 UT5EC (
439/449), 0428 SM3AKW (439/549), 0452 I5CTE (439/439) for initial #191,
0510 G3LTF (449/549), 0623 KA0RYT (449/O) #192 and 0633 OE5EYM (439/449).
I CWNR G4ALH. All QSOs were on random, as usual.
Peter found Sept conditions quite good, but not as good as in Aug --
I worked on 432 the following: on 19 Sept UT5EC, on 20 Sept JH4JLV, SM3AKW,
KA0RYT, K5WXN, IK2EAD, I5CTE, DL6WU, G4ERG, G3SEK, HP3XUG for initial #318, JA5OVU and JA3IAF, and on 21 Sept OZ4MM, I2COR, G3HUL and EA3DXU. Heard were N9AB, UA6LGH, DL4KG, PA2CHR and UR5LX. CWNR were DF6NA and ON4KNG. On 1296 I worked on 20 Sept IK6EIW,
EA6ADW, W2UHI, OH2AXH on SSB, F5PL, ON5RR, W4OP, N6BQ, DJ9YW, SM4DHN, KB2AH,
VEIALQ and DK7LJ on SSB. CWNR was JH5LUZ. After about 0730 1296 went dead!
Peter's 432 report -- I worked on 30 Aug 7M2PDT (M/O) for initial
#76 and JH4JLV (M/M), and on 19/21 Sept JA5OVU (449/449), UT5EC (449/559)
#77, HB9SV (559/549), KB3PD (O/O) #78, G3LTF (549/449), ON4KNG (O/O), OZ4MM
(549/449), UR5LX (O/O), partial KA0RYT (O/O) - no R's and OE5JFL (559/449).
There were lots of getaways -- CWNR or QRZ'd K5WXN, PA2CHR, N9AB, JA3IAF,
JA2KRW, I2COR and G3HUL. I also heard DF9QX, G3SEK, DL4KG, OK1KIR,
DL6WU, SM3AKW, IK2EAD, I5CTE, OE5EYM, JA9BOH, DK2WG, JA4BLC and G4ALH.
Conditions were reasonable, but deep/rapid QSB made copy quite difficult
at times. I didn't find time to hook up the new HV supply before the SW.
I am hoping to get it sorted out before the contest. In the meantime
I've recommenced work on an amplifier that I started some time ago.
Louis was not able to respond to his e-mail this month - [not clear
why]. He was active on 70 cm Saturday and Sunday of the SW and worked G3LTF,
KA0RYT, VE1ALQ, JA2KRW and KB3PD. Louis reports LU4HO will be QRV for the
ARRL Contest, and operate on 432.022 or 432.029.
Yoshiro reports on the ARI Contest weekend -- I was only able to
operate during my Eur windows. On 20 Sept I worked Karl, SM3AKW on 3 bands
(144, 432 and 1296) within one hour! We 1st had a sked on 2 m, but could
have worked on random (O/O). Then we worked (549/549) on 1296 on random at
2216. At the end of this QSO, Karl asked me to QSY to 432. We finished with
a 70 cm QSO (439/539) at 2225. Others worked were on 432 UR5LX, DK3WG,
ON4KNG and ON5FF, and on 1296 DJ9YW, G3LTF, HB9SV, JH5LUZ, IK6EIW, HB9BBD
Shigeru is relatively new to 432 EME -- I first enjoyed "moonbounce"
in the last ARRL EME completion. At that time my RF output was only 60 w at
the feed point. This year my new power amp (about 400 w output solid state)
is ready. I will be looking QSOs in the contest with 4 x K1FO 22 yagis.
My address is (SHIGERU TAKEDA, HIGASHI 5-11-1 SATTE, SAITAMA, 340-01 JAPAN)

Steve found 70 cm signals excellent during the Sept SW. Activity from
Japan was very good in Sept. Although he has said it many times before,
Steve is still amazed how conditions and activity improve when Sept arrives.
Stations worked were on 14 Sept KA0RYT and EA8FF and on 15 Sept NA4N - all
with grid square exchanges for ARRL VHF contest QSOs, and on 19 Sept JO3RNL,
on 20 Sept CT1DMK, S52CW, NA4N, UA6LGH, JA2TY, JA9BOH, JA3IAF, JH4JLV,
JA5OVU and JA2KRW - heard were JH1EFA and JR9NWC. Steve started to give
JR9NWC a call on 21 Sept but noticed that his HV didn't seem quite right.
Checking the power supply he found one of the diode blocks in the bridge
rectifier was very hot and had a burnt smell. Since he had 2 of the other
10KV/1A diode blocks fail in a past EME contest, he decided to build up a
replacement rectifier bridge using old fashioned strings of 1N5408 (3A/1KV)
diodes like he uses in his PS-70 power supplies. The 1N5408 diodes are low
cost and with their 200 A surge rating he has never had problems with them.
Steve worked on 27 Sept G4ERG, N2IQU, DL4KG and JA5OVU, and on 28 Sept W8MQW
and N2IQU. Steve reports that the Sun is coming back to life. Sun noise has
been varying around a bit and Sun activity is definitely on the up swing as
his Sun noise measurements are inching up. He measured 18.4 dB on 20 Sept
and 19.0 dB on 27 Sept; up over a dB from the end of Aug. Steve has
resurrected an old 386/40 computer to dedicate to Realtrack and other EME
software. The separate computer, with its monitor above the operating desk,
is a big convenience improvement. When going through his computer junk box
he found a 286/12.5 motherboard. It's available for free to anyone who would
use it for EME tracking. The board looks like it has built in EGA, 2 serial,
1 parallel and a PS/2 mouse port plus 4 Mb of RAM plugged in it. 70 cm EME
totals for K1FO are initial #513, WAS 49 and DXCC 75.
Randy has completed a 4 tube (air cooled) PA for 23 cm -- I am
getting well over 300 w out. Unfortunately it's very thermally unstable.
I tried some larger blowers; better but still not usable. I have some
larger ones to try with a little better venting, but I am starting to be
very pessimistic, and am beginning to think it's not possible to air cool
7289's at this power level. I guess I'll probably end up going the water
route or returning to solid state. In any event, I will continue to play,
and am still hopeful of having something up and running for the contest on
Rick reports success on his 432 skeds during the Sept SW with HP3XUG,
G4ERG, partial IW5AVM - heard for 30 sec on his 3rd sequence then nil, nil
HA1YA and 7M2PDT cancelled because of high SWR.
John in (EM17) had skeds on 70 cm with 7M2PDT in Aug and Sept, but
heard nothing both times. He did copy K1FO on 20 Sept at 1400, but didn't
have time for a QSO. John plans to be active on 432 during the contest.
Anders ran with the JAs on 13 cm in Sept. He had a partial with
JA7BMB due to 2424 receive problems, but could still copy both stations (O)
with only 7 dB of sun noise on 2324. Anders is getting 16.1 dB of Sun noise
on 2320 and 17.2 dB on 2304. All 3 of his receive converters have a .55 NF,
but do not perform the same on line. JA4BLC had problems with high winds.
During the SW Anders CWNR ZS6AXT (539) on 2304, copied nil from OK1KIR on
sked, was called on .050 from 0450 to 0543Z by an unidentified station with
a very rough CW signal, and worked WB5LUA (569/M) for initial #6. Nothing
was heard from W4HHK or WA8WZG on sked. Anders plans to stay on 13 cm
through the winter because of his noise problem on 23 cm, and therefore
needs more power for 2300 operation. He is looking for a 13 cm amplifier
with 70-100 w preferably for a 2C39BA or 7289.
Hoppie's Sept 23 cm report -- Due to business travel I haven't been
QRV since the June SW during which my operating time was cut short by a
water leak in the PA. The water got into the HVPS! I had planned to operate
on Saturday morning (20 Sept), but attended a social function with the XYL
at a local winery. After a four-course meal and several bottles of wine, I
had forgotten the Morse code by moonrise, so it was off to bed instead of
EME. However, Sunday morning (21 Sept) I was finally ready and able to play
EME. Conditions were great and so was the activity. I was able to make 16
QSOs in the 1st 3 hours. I had a near miss with NL7F, then off to bed. I
got up for the JA window and snagged K4QI for QSO 17, but no JAs were heard
during 1.5 hours of calling CQ. Stations worked were as follows: W4OP, G3LTF,
F5PL, OH2AXH, SM4DHN, ON5RR, DJ9YW, SM3AKW, W2UHI, EA6ADW, VE1ALQ, OE9XXI,
DL0SHF, F6CGJ, OE5JFL, OK1KIR and K4QI. I almost worked NL7F and heard but
didn't work KB2AH and K5JL (who apparently went to bed early). I was hearing
OE9XXI at (579) on my "lil" 3.7 m dish and was reminded of the big signal
from VE3ONT (unbelievably strong). All stations had very good signals and
it looks as though this years' ARRL contest will have some great competition.
I was using a TH328 driving a DL9EBL-built TH-327 cavity amp at 900 w
output in the shack. The TH-327 is a very "thirsty" tube and I was pulling
about 1.3 A. This power level is about the maximum for the ham shack's
20 A/230 VAC circuit breaker. I believe it's now time to upgrade the ham
shack mains breaker - HI. I was only using 2.3 kV dc under load, so this was
one reason for the high anode current at only 900 w. For Oct I'll raise the
anode voltage to approx 3.3 kV under load, which should help a bit. The new
PA worked beautifully and required no retuning all through the EME session.
My next project is to install a KB2AH feed with built-in polarizer and 7/16
connector on the TX input, so the new PA won't destroy any N-connectors or
the Quad Hybrid which is currently being used. I'm keeping my fingers
crossed. that I'll be home instead of in Australia during the Oct contest
Greg writes -- I installed a cavity filter and cleaned up a few
connectors to get my Sun noise back up where it use to be, and started
hearing stations again. I worked on both 15 and 20 Aug K1FO, and on 21 Sept
UR5LX and N9AB for an initial - who had a good signal. I am looking forward
to getting on during the contest. I have the week off. My house is still up
for sale. I am going to try to stay up and running until it's sold. I still
need QSLs from the following: OH2PO, NC1I, SM4IVE, K5GW, N4GJV and K5JL.
My correct address is 6608 Kelly Rd, Warrenton, Va. 20187.
Frank's array is on the ground for repair. He hopes to have it back up
in time for the ARRL EME contest, but it is going to be difficult to make
the repairs and put the array back on the mount in the next few weeks.
Bill's report for the Sept SW follows -- After spending the summer
repairing/modifying old antennas and building new ones, and repairing the
preamp, I am back on 1296 EME. Random contacts were made on 21 Sept with
OE5JFL (M/O) for initial #27, F6CGJ (M/O) and VE1ALQ (M/M). The repaired
preamp still needs work. Sun and CS/G noise are down about 3 dB. As soon as
I get a supply of transistors I will begin playing. [Bill can be reached via
e- mail for skeds at: Bill, NL7F ]
Pertti passes on the following Sept SW info -- I was QRV on 1296 and
QSO'd on 21 Sept SM3AKW (579/569), ON5RR (559/569), W4OP (559/559), K5JL
(569/569), KB2AH (569/569), F5PL (559/559), EA6ADW (559/559), N6BQ (559/559), S59DCD (449/449), DK7LJ (56/55) on SSB,
G3LTF (54/55) and ON5RR (35/55) on SSB. I now have fixed my 2.3 GHz
converter/preamp, and am hearing my own echoes with a few watts. Sked
partners for 3400.100 MHz are also wanted! Unfortunately we have only
3400-3408 MHz in Finland and thus I cannot work on 3456 MHz. My echoes
on 3.4 GHz were heard in Aug with 7 w. Now the power has been increased to
12 w. I will be QRV in the ARRL contest as usual.
eter was QRV for the ARI Contest -- After a few months of
inactivity, I was on for the ARI Contest. I contacted on 20/21 Sept:
SM3AKW, IK2EAD, KA0RYT, G4ERG, G3HUL, DL9NDD, OZ4MM, UR5LX, EA8FF, ON5OF,
I2COR, OE5JFL, DL3EAG, JA5OVU, JA9BOH, JA4BLC, JA2KRW and 7M2PDT. Heard were
K1FO, OK1KIR, DL6WU, HA1YA, DL4KG and CT1DMK. Conditions were the better
toward the end of the contest - (Sunday from my moonrise at 2100 to the end).
One week before I went to WEINHEIM and met some of EMEers. Pictures of them
are on my home page:
Marc was again active on 23 cm in Sept -- We made our 1st SSB
contacts using only 120 w in the shack! We started at around midnight with
very little activity and bad, unstable propagation. Conditions improved a
lot after 0400, with the opening of the NA window. The highlight of this
Sunday's activity was working OH2AXH and DK7LJ on SSB - not so bad for an
air cooled 120 w PA and a 6 m dish. The following random QSOs were made
HB9SV, GW3XYW, OH2AXH (CW and SSB), G3LTF, SM4DHN, F6CGJ, K5JL, ZS6AXT,
VE1ALQ, SM3AKW, KB2AH, OE9XXI, N2IQU, N6BQ, OE5JFL, DJ9YW, W2UHI, DK7LJ,
DL0SHF and W4OP. Initials were W4OP, DK7LJ and DL0SHF to bring us to #44.
CWNR were DF3RU, S59DCD (for 1 hour) and F5PL. Heard were JH5LUZ and EA6ADW.
Nil was achieved on skeds with S59DCD and HA1YA. I will be QRV in the ARRL
Contest and looking for more 1296 QSOs.
Stig stayed on 432 for the Sept SW -- I was on 432 and only QRV for a
few hours in the morning. I found condx were down on Sunday compared with
Saturday. I QSO'd on 20 sept OE5EYM for initial #135, WI7Z, IN3KLQ, G4ERG,
CT1DMK, ON4KNG and SM3AKW, and on 21 Sept UR5LX, EA8FF, KA0RYT, I2COR,
G3SEK, DL6NAA, S52CW, DL4KG, ON5OF, G3HUL, EA3DXU, G3LTF and DF9QX.
Sergej (KO85ws) has completed the 1st EME QSO from Russia on 10 GHz!
He worked on 20 Sept WB5LUA (M/M) for initial #1 followed by WA7CJO (O/O) #2.
He has a 1.8 m dish and 30 w TWTA. Serej is receiving 11 dB of Sun noise and
0.9 dB of Moon noise. QSLs should be sent to PO Box 462, Moskwa, Russia
111555. He is interested in skeds.
Sergej was active on 20-21 Sept on 432 in the ARI Contest and
completed 32 QSOs. On 25 Aug he worked W5ZN (O/O) for intial #320 and WAS
39. Sergej is now using a new 1" Heliax feedline which has gained him 2 dB
of power TNX to DF6NA and DH9NDD. He also reports that UA9XEA will be soon
QRV again on 432 with 4 x F9FT yagis and 500 w from a new QTH in LP63un.
Darrell found band conditions excellent on both 70 cm and 23 cm
during the Sept SW -- I was not active for very long periods. I started on
70 cm at 0215 on 20 Sept and remained there until 0430.(As I was not feeling
the greatest and I went to bed). I added 2 initials on 70 cm: CT1DMK
(539/559) #125 - fantastic signal from Luis, and WA7BBM (559/449) #126.
I did not rotate polarity with WA7BBM, perhaps I should have, because Luis
peaked at 45 deg form horiz, which seemed to be consistent with all signals
form across the Atlantic. My own echoes on 70 cm remained very steady at
around S6, and I thought conditions were much better than they have been
for some time. I also worked on 70 cm HP3XUG and JA9BOH. A number of others
were heard but not worked. Conditions on 23 cm were also found to be
exceptionally good. There was a slight indication of QSB, but libration
disturbances seemed non-existent. I was on 23 cm form 0700 to 1100, when
all activity seemed to stop except for N6BQ (S6). All signals on 23 cm were
very, very strong, W2UHI was S5 to S6. OE9XXI was notably strong at 20 dB
over S9 (with peak "hold" S meter turned on). Other stations worked were
OE5JFL (589/569) for initial #83, DL0SHF (579), SM4DHN (569), SM3AKW (569),
F6CGJ (589), DJ9YW (559), N6BQ (569), ON5RR (539), G3LTF (539) and NL7F (529)
- I had one heck of a time getting him to hear. With so many strong signals,
there was no noticable SSB, at least below .025. This was very pleasant,
especially when working the lighter stations. I remember my activities on
2 m EME, when SSB was suggested, we automatically went to 144.110. Perhaps
this can be, or should be done on all the EME bands? [SSB is illegal below
.100 in the USA on 144. Similar regulations do not exist on 432 or 1296.
Perhaps we need an SSB calling frequency on 1296.] My plans for the ARRL
EME Contest are to operate 70 cm the 1st Moon of each half of the contest,
then go to 23 cm for the 2nd in each half.
Willie has not been QRV the last 3 or 4 months, because he has been
working on a new dish (32' with a f/d of .55 and 24 ribs - the ribs were
built 2 or 3 years ago). Willie took down his old 24' dish on 13 Sept.
He hopes to have the new dish up and working by late Oct or early Nov, on
432 1st and later in the winter on 1296. His older dish is now available -
see the FOR SALE section of this NL.
Dale has finished his KB2AH 4 x 7289 HPA and is getting a stable 500W
out -- I am very glad I included a flow meter on the front panel. I
originally considered it window dressing, but find it a real comfort to know
the water system is moving. The rest of my setup is a 12' dish on H/H mount,
KB2AH feed and preamp, and 40' of 7/8" hardline to dish. I worked on 23 cm
on 20 Sept K2UYH, EA6ADW, SM3AKW and F6CGJ, and on 21 Sept K5JL, OH2AXH for
initial #28, F5PL, KB2AH, W2UHI, ZS6AXT, G3LTF, N6BQ, ON5RR #29 and DJ9YW.
Dick (x-N4EL) who was formally QRV on 70 cm EME from NJ is now
located in Ala. He brings us up-to-date on his EME plans -- I sold my 70 cm
amp when I left NJ in '88. So I am looking for a GOOD and BIG 70 cm amp to
get back on EME. I have for sale or trade a very nice N6CA 23 cm amp
(single tube) built in a cabinet with power supply. I've never tested it,
but I believe it is in wonderful condition. It belonged at one time to a
23 cm EME operator from Colo. I think it was used to drive a larger 23 cm
Paul (DM12ju) is now QRV on 3 cm EME -_ I made my 1st 10 GHz EME
QSO on 28 Sept with WA7CJO, and on 30 Sept added WB5LUA (449/O). I borrowed
a TWTA from Bill (W4TJ), repaired the power supply and increased the power
from 19 to 26 w. I also extended the supply wires for the TWT so that I have
TWT mounted very close to the feed horn. (I repaired the power supply for my
own TWT. It had many problems. Finally I was forced to rewind one of the
ferrite transformers between push-pull stages. Also one CMOS IC, a
transistor and an electrolytic capacitor were
bad. Someone else before me tried to repair this power supply. I also
confirmed that my own TWT - Thomson TH3631W is definitely bad. Now I have to
find a TWT for myself.) My dish is 10' with f/d of 0.29 and a linear
polarized Chaparral feed. I measured the illumination of my dish. At the
edges in the horiz plane it is -12 dB and in vert plane -13 dB using the
Chaparral feed with three chokes. My RX system consists of an isolation
relay, G3WDG LNA followed by a 3 stage LNA having an NF of 2.2 dB and gain
of 28 dB, and 2.4 m of RG223 down to the transverter. The transverter has 3
ports for 144 MHz, one for the transceiver, the 2nd for the main receiver
and the 3rd for a power meter for dish aiming. I am using a standard IC202
as RX-TX transceiver and my old modified IC202 as a main RX. For dish aiming
I am using a prototype of milliwatt meter 20-2000 MHz, which I developed
many years ago for professional use. The TX output from the transverter is
23 dBm which goes through 3 m of RG223 and a 3 dB pad to the TWT input. The
TWT is hanging at the focus of the dish and is connected through a 30 cm
PTFE coax line (similar to RG223) and 2 relays to the feed horn. The
transverter and TWT power supply are mounted at the back of the reflector.
I found a degradation in the RX system when everything is warmed by the Sun
at an ambient temperature of about 90 deg F. NF of the 1st LNA will of
course rise, but possibly the bias is also changing. I will add a servo to
maintain the bias to my G3WDG LNA and check again. Total NF measured at the
bench is 1.6 dB. When mounted on the dish I get only 1 dB of Moon noise.
Previously I had 1.7 dB of Moon noise with a preamp NF of 2.1 dB directly
attached to the feed horn. The feed horn alone has a return loss of < -20 dB.
I will be QRV in the contest on 144 and 10 GHz. My window for Eur is very
short. So I prefer to wait with NA stations until after my Eur window is
over. My e-mail is: Paul, SM0PYP ,
phone/fax at home (619)-623-9693.
Charlie has not been active for the last 3 months due to problems
with his elevation drive -- I am currently working on gear box which had
stripped motor gears. It was very hard to get replacement parts. I just
completed a 7000 volt power supply for my klystrons on 23 and 13 cm. I hope
to have them on in time for the contest. I am having trouble getting
connectors that will stand the power. WA8WZG is working on it. I am
finally on e-mail at: Charlie, W7GBI
Al had excellent results during the Sept SW. He worked on 2304
LA8LF, on 3456 NU7Z, and on 10,368 I4CHY, DF0OVH and RW3PB all for initials.
He says he was amazed by RW3PB's signal level. He also had a nice 3 cm SSB
QSO with WA7CJO. Al asks (on 23 cm) if DC6UW, DK7LJ and DJ7FJ are all
initials or do they share the same station. [DC6UW is definitely a separate
station. I believe DK7LJ and DJ7FJ are also different, but DK7LJ may be
related to DK0SHF.]
Ian is setting up for 3 cm EME. He has 3 m dish, WDG LNA, feedhorn
and tracking system - all home brew. His LO and mixer are on loan from G3WDG. He says "Once basic receive capability has been demonstrated I will be able get going on TX as well". Ian is located (PO Box 825, Randpark Ridge 2156, South Africa), tel: 27 11 7
Ivo writes -- During the Italian Contest I tried my luck on 13 cm,
but nobody was there. (Later I learned that LA8LF called me with his QRP,
but by then I was probably so tired, that I missed him.) So I went to 23 cm
and worked on 20 Sept SM3AKW, N2IQU, KB2AH, W2UHI and K5JL, and on 21 Sept
OH2AXH, G3LTF, K5JL, W4OP, F5PL, ON5RR, EA3ADW, W2UHI, DJ9YW, JA4BLC and
HB9BBD. CWNR were DF3RU and JH5LUZ. (No Italian stations?) Signals were
generally very good and weather here was also very good. Of course my Moon
window is shorter especially to the west. On 28 Sept I worked on 1296 F1ANH,
DD1XF and DJ9YW. So there is 1296 activity outside the SW. Slow progress
here on 6 cm, but I hope to be QRV soon. There is relatively little info
available on 6 cm equipment. I hope that the activity during the ARRL
Contest will be better, especially on 13 cm.
Family commitments again limited my operating time. I was only able
to be QRV on Saturday and decided to stay on 1296 for the single day.
Conditions seemed good and there was lots of SSB activity. At 0447 I called
CQ and immediately became involved in a 3 way SSB QSO with KB2AH (57/57),
W2UHI (55/56) and K5JL (56/56). Jay was having some problems with his audio
but was still Q5 off the Moon. This was followed by contacts at 0516 DK7LJ
(57/55) on SSB in JO54cg, 0545 W4OP (559/569), 0603 SM3AKW (55/54) on SSB,
0612 EA6ADW (55/44) on SSB, 0640 I2COR (?) - I thought they called, but I
never copied them again and 0700 F6CGJ (57/56) on SSB.

This month we have a very interesting article by Chuck, W8MQW
on "Hearing CW in Noise" which raises a number of intriguing questions.
Next month there will be an up-date on VE1ALQ's linear encoder board.
Congratulations to Charlie, W7GBI on his 80th Birthday!
* There seems to be more and more SSB activity on 1296. Although this is
good, it does pose a problem as pointed out by VE1ALQ: the SSB can
interfere with weaker CW stations. One solution is to have an SSB calling
frequency around which SSB activity could congregate. I do not think we
want to put this frequency too high up in the band. .100 is not good as
this is the tropo calling frequency in NA. We also do not want SSB activity
to interfere with a small station calling frequency - although I have not
heard much about this idea in recent months. Would a 1296 SSB calling
frequency at .025 or .030 make sense?
* There has been quite a bit of discussion on the 20 m net on the new RF
radiation safety standards the USA is now instituting for amateur as well
as commercial stations. These standards may be more of a problem to stations
using smaller antennas since are power is distributed across the large
aperture of our arrays/dishes. K2DH notes regarding the comments in Sept
QST related to field strength that low band stations with ground mounted
antennas will really feel the effect of these new rules. EME type
"stations" will have the consideration of ant pattern, freq, time duration
etc. Time of exposure to radiation is of prime consideration.
* I want to again express my thanks for the many messages of condolence
I received on the passing of my father. It makes me appreciate the
closeness of our "EME family".
* I know I do not need to remind you to submit operating new with the EME
Contest coming up, but please keep the technical material coming too.
I hope to give all of you some points during the contest.
