We seem to be in the dog days of summer before summer has really begun. The end of May SW did not produce particularly great conditions, but the main complaint was activity. The truth is that we have had an exciting winter and spring with lots of contests, now we need an exciting summer with summertime dxpeditions to attract the troops back to the bands. Some of these dxpeditions are happening, but there has been little in the way of fanfare to make their presence known. For example TK/DC3VW/p is on the Island of Corsica with 8 vertically stacked yagis and 200 w. Enough to easily work DL9NDD. Another possibility according to K5JL is activity from TI2NA in Costa Rico. Letís get the word out and those summertime dxpeditions rolling!

PARIS 1998

The 8th 432 MHz and Above EME Conference is little more than a month away. Information and up-dates can be found on the conference Web page:

EME Paris 1998

The following have registered:
There is still some room left at this time, but you need to book quickly because July and Aug are a high tourist season in PARIS. Please remember that your articles must be sent to F5HRY as soon as possible, and before 15 June (the time limit before the printing). The WEB pages have recently been updated with your photos. Please continue to send photos (you and your antennas to F1EHN).


The results 1st EME SSB Contest have not changed much since the Feb NL. OE9XXI is still in 1st place with 48x13 for 624 points. (48 is 2 x the number of SSB QSOs plus 1 x the CW/SSB QSOs). Unfortunately there are a number of stations which should have scorer high but never submitted their logs. OH2AXH and K2DH have to be among these. Because of this I (K2UYH) am in 2nd place with 35x9 for 315 points and W2UHI 24x10 for 240 in 3rd place followed by G3LTF with 25x7 for 175. Certificates will be awarded at the Paris Conference. The 2nd EME SSB Contest is planned for the Feb SW of '99. Is there any interest in extending the contest from 1296 to 70 cm or 13 cm?

Frank was active on 1296 for the 2nd May SW. He worked the following on random: TM8EME, G3LQR and OZ6OL. All QSOs were initials. For skeds contact Frank at e-mail:
Frank, DD1XF

Guenter is now QRV on 23 cm and was active during the 2nd May SW. His rig at present is a 5 m dish with 70 w at the feed. Guenter plans to extended his dish to 6 m later. Guenter's e-mail address is:
Guenter, DF4PV

Csaba's (HA5BGL) group was active on 1296 on the weekend after the SW and are available for skeds. They are located in JN97mn and equipment with a 3.6 m dish with linear horizontal pol, 100 w at the feed and a FHX35 preamp. They follow the Moon by a telescope, so they can only operate at night when it is dark. Csaba is interested in skeds with "bigger" stations and can be reached by e-mail at:
Csaba, HA5BGL

Andrea (JN53fu) writes -- I found excellent 432 conditions in the presked weekend (perigee), but very low activity. Anyway I was very happy because I worked 2 more 4 yagis stations with my 2 x 28 el 9 wl yagis and 800 w. It is interesting what QRP can do if one finds the right polarization shift HI! I worked on 23 May K5JL (539/559) UFB for initial #26, W7QX (O/O) #27 - my 2nd 4 yagis station, heard was K7XD (M/-) and nil KB3PD due to local QRM but he copied me, on 24 May W7CNK (O/O) #28 - my 3rd 4 yagi QSO, and 31 May OE5EYM (539/O) on random and nil F1AHN.

Steve has been extremely busy with little time for EME or ham radio in general. He spent quite a bit of time this spring looking for land to build a new house. If he were to put up his 28' Kennedy dish at his present location he would have a limited window due to tree blockage. Unfortunately, the only property that he was able to find that met all the requirements, dish window, good tropo location, buildable lot and plenty of privacy was quite a bit farther out in the country than where he presently lives and not where either he or his wife want to live. At his present location there are only 5 houses within a half mile (.8 Km) radius. Most of the surrounding land is part of a water reservoir and open space land trust, very good for ham radio. He is now planning on expanding and remodeling his present house. The job of developing the plans and finding a contractor has more recently occupied his time. The plans include building a new larger shack on the 1st floor to replace his somewhat small shack over the garage. If he proceeds ahead with the plans his present shack will have to be dismantled before the renovations start. In addition all the feedlines will have to be dug up putting him off the air for several months. He and his wife are attempting to make a decision as to whether the results of the remodel will be worth the pain of doing it. In addition to the house work he has been very busy at work and with Lunar-Link Systems. Steve was up at the Rochester, NY hamfest and chewed the fat with the 70 cm and up EMEers who were there. Stations worked past months were on 8 Mar I5TDJ and WB0GGM, on 4 Apr K5WXN, DF3RU and DL4KG, on 30 Apr W7CNK, KA0RYT and JA5OVU, exchanged grid squares with KA0RYT and JA5OVU for the 432 ARRL Spring Sprint Contest, on 1 May VK4KAZ (M/O) #533, DL9KR, and W7CNK, on 2 May JA9BOH, K7XD, N2IQU, JA3SGR, JA3IAF, JH4JLV and JJ1NNJ, on 31 May K5JL, W7CNK and JA5OVU, and on 7 June W7CNK. Steve's polarity rotor (an HDR- 300) again has output shaft keyway problems and now has at least 45 degs of backlash in it. He is just about giving up on the HDR- 300 as he feels the only way to fix the problems would be to go to a spline output shaft and gear, but he has been able to find suitable parts. Steve is considering using a prop pitch motor for polarity rotation, but it would require quite a bit of modification to his mount, plus they are slow and noisy. He looked at the M^2 worm drive rotor, but it is too high to fit into his mount. He is considering trying a Yaesu G-2800SDX rotor. On paper the braking torque looks very impressive, but the motor turning torque looks a bit marginal. He wonders if anyone has any experience with the G-2800SDX rotor? Steve's 70 cm EME totals are: #532 initials, 49 states and 75 DXCC. Svetlana is just now shipping their long awaited version of the 3CX800A7 triode. He has been testing a pair of Svetlana tubes in an LA-70B, 70 cm amplifier. Initial tests look encouraging, the Svetlana tubes are very stable in terms of power output, operating just like a HF amplifier. They bias slightly different than the Eimac tubes, however and require more drive power. Lunar-Link Systems is now stocking both Eimac 3CPX800A7 pulse rated tubes and Svetlana 3CX800A7/3CPX800A7 tubes.

Harry is using a 3.2 m dish and 200 w on 1296 and writes -- I now have a max of 65 degs of elevation available so I can now take stateside skeds on 1296. I am good until I reach an azimuth of 205 deg where I am blocked by trees. One short window remains for me from 255 to 265 deg for above 35 degs of elevation. During the SW I worked K4QI 429), EA6ADW (O), nil EA3UM, PA3CSG (439), nil I6QGA, nil F2TU, nil GW3XYW, nil N2IQU, N6BQ (O) and K2UYH (549). Overall I worked every station heard, had 5 no shows on skeds and QSO'd 3 on random. My initial count is now 25.

Russ writes -- I was on 1296 over the activity weekend for a couple of short periods. Conditions seemed fairly good. I worked on 30 May W2UHI, N6BQ, DD1XF, OZ6OL for an initial (#), DF4PV #, K3HZO #, DF3RU, OK1KIR, OZ4MM and PY5ZBU #, and on 31 May W2UHI, HB9BBD (very loud) and K2UYH. Around 2020 on 30 May, I heard someone calling several times. They were very weak and sending very slow. With the slow CW, the libration chops a weak signal up to the point you really cannot copy anything. I missed the TM8EME tests last month because of very high winds the whole weekend. [Russ can be reached on e- mail at Russ, K4QI ]

Roger is presently not QRV due to the passing of his aunt. He is not sure when he can get back on. He is involved with settling her affairs. She was a teacher from 1944 to 1974 in Anchorage and amassed a lot of things, many of which are turning out to be historical in nature. Roger notes -- I'm sorry that this is happening but will let you folks know when I can get back on. Please let the gang know that I do not want any schedules as of yet. I don't want hurt feelings when I donít show up or don't answer my e-mail right away. I have had almost 50 messages alone. [You have the sympathy of the EME gang. We understand the situation and will be around when you are ready for the Moon again.]

Joe is QRV on 70 cm with 4 yagis and now has an LA-70 online running 1500 w. He worked DL9KR (569) on 2 May at 2200, but heard nil from DL9NDD on 3 May. You can reach Joe at:
Joe, KU3T

Hoppy's 23 cm activity report for May follows -- I QSO'd on 11 May W2UHI, on 23 May DJ9YW and OZ6OL for initial #122, on 24 May W2UHI, DL6YDH, DH0OAH #123 and DJ9YW, on 30 May W2UHI, KD4LT and K4QI, and on 31 May JA6CZD, W2UHI, W7GBI, HB9BBD, G3LTF, K2UYH, OE9ERC and K3HZO #124 . I had a near miss with K9BCT on schedule. No contact since I never copied Randy's Rs. Also I didn't hear anything from 9H1ES on schedule. I increased anode voltage on the TH-327 PA to 3.0 kV dc under load and ran 1.5 kW output for several hours straight with no big bangs! I ran approx 1.3 kW during the entire weekend with very stable operation. The new method of disabling HV and Esg during RX seems to be working. A new feed, VE4MA with built-in polarizer section and 7/16 con- nector on TX port is almost ready to be installed.

Shawn is now QRV on 432 from DM09 (Reno, NV). He is be- lieved to be running close to the legal limit into 4 x 25 el FO yagis. Ron, KA0RYT reports working Shawn (M/O) and says he will be temporarily down to move his array to a rarer grid for the ARRL June contest - portable style.

Zdenek sends the following report on his 1296 activity during the 30/31 May SW -- I worked OZ4MM (O/M), OK1KIR (O/O) and HB9BBD (559/539) - very strong signal with peaks to 579. Heard were ON5RR, OZ6OL, K4QI, DF3RU, N6BQ, LU6DW, OE9XXI and OH2DG. I used 150 w. I have a new preamplifier made by OK1CA with 0.5 dB NF. Receiving side is thereby very much better. In next 2 windows, I am sorry to say, I will not be active. I will work on completing a higher power amplifier with a TH338 for the next time I am able to be QRV.

Marc, just back from the Italian EME convention, writes -- We intended to work all our skeds, but had problems. When we came on we heard HB9BBD with an outstanding signal. His 10 m dish is doing a great job! It was easier to work Dominique than ever before. Then I got on the sked freq, but during echo testing the EHT of the driver blew. I tried a backup one, but the only thing it wanted to do was oscillate. It even killed the OZ9CR amplifier... Finally I used my 1st amplifier (2x2C39). With reduced drive and EHT I could only make about 60 w. I could hear my own echoes, but nil on all skeds. I heard very weakly PY5ZBU and worked some big guns. We are busy making repairs and hope to be active in June.

Stig was QRV on 1296 for the SW -- I worked some stations, but didn't find activity too good. Conditions like activity seemed down. QSO'd on Saturday were HB9BBD (57/56) on SSB, DF4PV (529/449) for initial #140, JA6CZD (559/569), DF3RU (549/569), OK1DFC (M/O) - much weaker than normal, OZ6OL (549/559), IK2RTI (439/549) #141, LU4DHD (O/549) #142 DXCC 36 and JR9NWC (M/O) #143. Back in beginning of May I worked TM8EME (59/58) on SSB. Concerning my e-mail address, there was an error in last NL! The address should be:
Stig, OZ4MM

Hans writes -- I was QRV for the TM8EME tests and re- ceived good signals from them but did not succeed in making a contact. Several lessons were learned. Misalignment of the dish was the 1st and biggest mistake. Measuring the Sun noise helped me discover the alignment problem. 2nd was the NF of my preamp. Measuring only 8 dB of Sun noise indicated that much improvement could be realized in building a new preamp. I am building a DJ9BV design with a HEMT to replace the old MGF1302 preamp. The biggest surprise was that during the TM8EME activity I heard several other stations on the same frequency as TM8EME. This gave me my last lesson that my CW knowledge must be improved. Activity from my side will be to build a dish and perhaps do some tests with my 2.5 m dish. The spark is glowing and something will result.

Jerry heard nil on 23 May from W7CNK, HP3XUG and K5JL. He notes that he will be away in SV9 from 29 May to 2 June for a 2m EME and MS dxpeditions. He will be again QRV on 70 cm on the weekend of 20-21 June. On the weekend of 27/28 June he will be away from Athens on a business trip.

Jeremy in ID (DN14wv) is just about set for EME operation on 70 cm with 8 x 432cp42ug modified cross yagis and 800 w from a pair of 4CX250Rs. Jeremy has stereo RX via FT1000mps, dual stage preamps and separate feeders. He notes that 222 and 13 cm EME are in the works, but that 23 cm is on the back burner. He expects to be QRV in June pending some tree removal. His address is (Jeremy Alexander, PO Box 1818 McCall, ID 83638), tel 208-634- 4466 and e-mail:
Jeremy, W7EME
[PA problems have delay Jeremy, but he expects to be QRV very soon.]

I was only able to be on one day during the SW and chose to try 1296 as I was on 432 last month. Conditions did not seem very good, but I did QSO on 31 May at 1921 HB9BBD (57/54) on SSB with an immense signal, 1944 OZ6OZ (549/559) for initial #153, 0200 K4QI (559/559), 2021 K3HZO (549/O) #154, 2032 N6NB (559/549), 2043 G3LTF (559/549) and 2100 OE9ERC (56/56) on SSB. I was again on 1296 the post SW and worked on sked on 6 June at 2330 HA5SHF (O/O) for #155 and DXCC 37. Signals were up and down due to tree blockage at the low declination. I used circular pol even though HA5SHF was linear as I did not read his e-mail carefully. Afterwards, at 0010 W2UHI was QSO'd (55/44) on SSB, but signals were erratic due to the tree problems. I also ran several skeds with VK4KAZ on 432, but only copied pieces of calls. My window to the west has just about disappeared! I may have to wait until the leaves come off the trees before I can work him.

This month we have a modification for the UPX-4 and similar 6 tube ring amps from G3LTF. Peter writes -- for sometime I have struggled with various input circuit arrangements for my home brew 6 tube 3CX100A5 amp. I used loops and direct ground taps from the sidewall, but I believed these all upset the symmetry of the cavity operation. I recently changed to a direct tap on the central tuning slug. This seems to do the job with much better balance of currents in the tubes - see the diagram at the end of this NL. The dimensions are approximate. You may have to experiment.

Also in this NL is the list of stations on microwave EME prepared by NU7Z.

JF1EFA with 4 x 26el K1FO Array

JF1EPA's Solid State 432 HPA
8 x 2C33102 for 600 W Output at 432 MHz.


This month there was only a 3 week turn around between SWs. Unfortunately we have to leave for a business trip on the weekend we would normally prepare the NL. Thus the NL is a week later than normal. I am sorry for this delay, but there was nothing I could do. The rest of the summer does not look much better. We will be away on another trip at the end of June and the will be gone again for several weeks for the PARIS Conference.

Recordings of the TM8EME QSOs have been uploaded to the WEB by F5MZN. Samples of all QSOs are available. The records are saved as WAV format, 8 KHz, 8 bits, mono. If you want to hear your signal or one of the others, connect to:

TM8EME Sound clips

and then after entering one directory, click on the file you want to listen. It can take some time before being able to listen a particular record. It depends of the file length and of the date rate available to you.

Thanks for the technical material and reports. Please keep the information coming. . I should be QRV in June SW and will be looking for you off the Moon.
