14.345, 10 AM ET SATURDAYS, AFTER VARO NET SUNDAYS:

CONDITIONS

The Italian contest generated some extra EME activity during the May skeds weekend (SW), but activity was down because of the Dayton Hamvention that attracts amateurs and EMEers from around the world. The big news this month is W2WD's dxpedition to Nebraska.

NEB 432 DXPEDITION: The W2WD/0 dxpedition is on. Warren will be operating during the weekend of 15/16 June from Bill's k9rz@radiks.net QTH in Neb. If you have not done so already contact Joe, K1RQG via the 20 m net or e-mail K1rqg@aol.com for skeds. Warren will always transmit on 432.030 during the 1st 2.5 min sequence and listen for sked stations on 432.030. He will also call CQ on 432.030 and listen for random calls from 432.030 to 432.040 unless otherwise advised. He will be listening 10 kHz (.040) high during skeds for random calls and will switch over to random, if a skeds station is not heard. He will be using a portable 20' dish with pol rotation and about 500 W from a 2 x 4CX300 PA. Murphy has been around. Warren's 4CX300s started flashing over, but he has received additional tubes from a number of sources and this problem appears under control. He has also been contacted by the 144 EMEers and will try to operate on 2 m as well. He says there seems to be more interest in Neb by the 144 gang. They are even sending him an antenna. [What about 1296? Unfortunately it was too late by the time Warren decided to consider additional bands. I think there is something here to be learned for the future!]


DF4PV
Guenther now has a terrific signal on 23 cm. He is QRV with a new 10 m dish See his web page at:

Guenther's WEB Page

He will make several improvements in the next few weeks. The transmission line will be replaced by a 7/8" Cellflex line. He is also searching for a long version of an IMU circular feed.

DL0EF
Manfred (PA3GLB/DL5FAB) sends results of his group's 10 GHz EME Activity during the Eur contest -- The crew of DL0EF

Manfred's WEB Page

was active on 10 GHz moon bounce during the DUBUS Contest on 20/21 April from the Astropeiler Stockert, located near Bad Muenstereifel (vicinity of Cologne) in JO30im. We were using our 10 m dish, polar mount and a 20 W transverter system. Moon noise was around 3 dB. We installed a magnetic polarizer unit, which proved valuable for large spatial offsets. We also replaced a modified satellite LNB with a DB6NT LNA, which improved the receive path. Increase in the ratio moon noise to colds-sky could not be observed anymore due to the big dish size. The activity started as planned, however, we run into problems with the antenna drive at around 2100 on the 20th, at the time of our sked with W6HD, which did not allow us to use the required slow gear to track the moon. Faultfinding revealed a problem with one of the motor drive couplings. The repair would require a major mechanical intervention, which was not possible during this weekend. We tried to continue operation by advancing the antenna in short but coarse steps and let the moon catch-up. The polar mount proved very valuable, as we need only to steer in GHA. QSO'd were on 20 April at 1622 I5PPE (O/449), 1642 G4NNS (O/O), 1658 F6CSX (439/O), 1734 OH2AXH (529/529) and 2205 WA7CJO (559/O). Also heard but not worked due to the antenna drive problems were W6YFC, CT1DMK, F2TU and K6RE. We want to thank everybody for the QSOs and we will be back in the air later in the year. Our plans are to increase our TX power by around 10 dB and further improve the control of the dish.

DL4MUP
Dave was active on 23 cm in the Eur EME Contest I QSO on 20 April HB9Q and G4CCH, and on 21 April F2TU for initial #35, HB9BBD, OZ6OL, F6KHM #36, OK1CA #37, HB9SV, OE9XXI, SM3AKW, F6CGJ, G3LTF, OZ4MM, OE9ERC, JA6AHB #38, ZS6AXT #39, K5JL, W4OP #40 and KA0Y. Just before the contest I replaced my preamp with a cavity design from K2AH. It proved difficult to get the NF better than my BV preamp, but finally with help from HB9BBD and DL4MEA a NF of 0.31 dB was achieved. Since the contest, I have added in skeds IK3COJ and SM6CKU to bring me to #42.

DL8OBU
Juergen in JO42xi has completed a dish for 23 cm EME and will be QRV during the June SW. He is measuring about 13-14 dB of sun noise and has already worked DJ9YW (O/M) and G4CCH (559/529) on random. He has 100 W at the feed, but is restrictions to AZ from 90-236 degs and EL from 10-50 degs.

DL9KR
Jan sends TNX to IS0/DJ5MN for initial #770 and DXCC #84 on 432. Jan says Bernhard had a nice (549) signal with 1 yagi and 500 W. Jan also worked VK3FMD #771 (2 yagis and 200 W) in May.

FR5DN
Phil (LG78qs) is now interested in 23 cm EME -- I have a 1.8 m solid dish, f/d about 0.28, and wonder if it is suitable for some EME work? I know that it's a small size, but it's hard to use a larger dish, as I would have to take all down and secured, as soon as there is a cyclone closed to the island. I have had to do this a number of times with my 2 m and 70 cm antennas. It's not fun, hi. For 1296, I think it's really marginal, so I'd like to know which band would be the best? [You're right about 23 cm. Some QSOs could be made with a high power PA. Unfortunately a 0.28 f/d is also very difficult to properly illuminate on any band. If you want to use this dish, 10 GHz is probably your best bet. For 23 cm I would suggest construction of a small stress dish with a mesh covering. A dish similar to N2UO's shown in the last NL would be a good choice. A 2.5 m dish would put you in business.] What about JT44 on EME, can that be a solution for marginal or QRP stations in the future? [There is growing interest in JT44 and should definitely help marginal stations. I'd still use a different antenna on 23 cm even a long yagi.]

G3LTF
Peter reasonable conditions but little activity in May -- On 432 on 18 May I worked DF3RU, F2TU, UA3PTW, K9SLQ for initial #358 and IN3AGI. I think he is also an initial but I'm not certain if he may have been a guest operator. He had a good signal. On 1296 I QSO'd on 18 May I0UGB, ZS6AXT, IK2MMB, JA6AHB, IK3COJ, G4CCH and W2UHI, and on 19 May on 13 cm JA4BLC (crossband to 2424) and F2TU (2320/2304). I heard and called ZS6AXT and SM3AKW, who is now very loud! I now have my new low backlash gear train, and the moon following system is working FB. I reckon to be within about 0.5 degree of the moon, which makes a big difference, especially on 13 cm. My next job is to re-cover the center 4 m's of the dish and trim its profile in preparation for operation on the higher bands. I'm hoping very much to work W2WD in Neb, which will leave only KY and WY for WAS!

G4DZU
Doug has problems back in April -- Despite spending a day checking out the station for the DUBUS contest, I was plagued with Murphy. I had problems for most of the session with my AZ readout and low output power. Even after all of that I still had an enjoyable time with some outstanding signals. HB9BBD was hitting S7 over noise in 1 kHz bandwidth. I worked 8 stations with 6 multipliers. My station is a 10' Andrews dish on an AZ/EL mount with a VK3UM controller, VE4MA feed/DJ9BV air hybrid, WD5AGO preamp, TX YD1336 cavity with only 300 W out (but when drive is ok 500 W).

I4TTZ
Vico, (I4ZAU) reports that his group was active on 10 GHz again during the May SW -- We worked on 18 May at 1503 IW4BTJ (519/52), 1531 I5PPE (O/O) and 2025 I4CHY (52/52) for 1st Italian two way SSB, and on 19 May at 1532 F2TU (O/O). Our station consisted of a 7 m Cassegrain dish, 60 W TX, 1 dB NF LNA in JN54vj (Bagnara di Romagna, Italy). The crew was I4BER, I4QIC, I4TMA, IW4BYP, IW4APQ, IZ4BEH and I4ZAU (ex I6ZAU). We plan to be QRV again for the June SW, and on 24 GHz next year.

K4EME
Cowles suffered a lightning hit in April that took out a lot of his equipment -- The azimuth rotor is dead along with my FT-736R and tracking computer. It appears that my 70 cm PA was unharmed. I had good grounds and surge protection on the antenna system. The strike appears to have come in on the phone lines. My bell box is in sad shape. I am in the process of getting things fixed, so I hope not to be down for long. I will let you know when I will be ready again for EME skeds. The good news is that I have acquired a 6.1 m solid aluminum dish.

K7XQ
Jeff CM97qi ran skeds on both 432 and 1296 with SM2CEW during the May SW. He heard nil in both, nor any random activity. He uses on 432 2 x 9 wl yagis and 300 W, and on 1296 a 3.3 m dish and 100 W.

N2UO
Marc has finished the surface of his 10' stress dish, and almost has everything else is ready for EME operation. The auto track is working and is getting 14 dB of sun noise. He hopes to be on 23 cm after a couple more days of work with low power (about 50 W at the feed) as he still needs to get his high power PA finished..

OK1CA
Franta is preparing equipment for 9 cm EME -- I have a 3 m dish with linear feed (vert or hor pol), FT736R and TRX with 15 W at the feed and a ATF36077 W5LUA LNA. My sun noise is 15.4 dB (SF162) and my moon noise is 0.5 dB. I have heard own echoes (M). I have a frequency problem, as the OK ham allocation is 3400 to 3402 MHz, but I can listen in the 3456-3458 MHz band. I tried a sked with W5LUA on 24 May, but I had a problem with my T/R relay. My rig is now ok and I am interested in skeds on 9 cm.

PA3DZL
Jac in JO21hm is now QRV on 13 cm EME (TX 2320). He can also RX on 2304 and 2424. Equipment is 2.50 m dish with VE4MA feed with built-in circulator, 30 W at the feed and 0.6dB NF. Jac is interested in skeds.

S59DCD
Rajko and Sil say -- "Punk is not dead" and S59DCD also is not, hi, just a little sleepy for a while. After our 1st successful 13 cm QSO with OE9XXI last Oct, we rested until now. In the May and June activity weekends S59DCD will be QRV on 13 cm with our 6 m dish and about 70 W for anyone who needs S5 on 13 cm. Skeds are welcome see my new e-mail address above. Otherwise we'll see you in Prague.

VK3FMD
Charlie in QF22mc is trying to arrange for some 70 cm EME skeds -- I am a small station with 21.6 dBi antenna gain and 200 W, but no elevation control (yet!) I have had success on 2 m EME with the bigger stations and the EME bug has bitten and I would now like to try 70 cm. [There is a big advantage to getting off the horizon, even with a fixed tilt on 432. This is because of the much lower skynoise.]

W2UHI
Frank as usual was QRV on 23 cm in May. He worked ZS6AXT, IK3COJ, G3LTF, G4CCH, W7BBM, DF4PV, IK2MMB, OZ4MM, F2TU and HB9BCD for initial #157 - all with good signals. He says his system is working well, but won't be active during the June SW due to family commitments.

W1ILP
Wilt in DN62uu is working on 70 and 23 cm EME and updates his status -- My station on 70 cm is basically operational. It consists of 6 x 22 el "FO" yagis, .5 dB NF MGF1302 LNA, 80' of 7/8" line and an FT847 driving a single 3CX800u7 to 450 W. A GS35B PA a'la' PA3CSG is on the way to completion. On 1296 I will advise when things are further along. I have a 6 x 7289 PA, but lack a driver, preamp and dish feed. My transverter is a real nice 10 mw job I "liberated" from WA4OFS. I will probably use a 10' TVRO dish, but the antenna is not yet decided. We are in a rental house and the winds are hellish here.

W4OP
Dale moved in May of 2000 from EL96 to EM85 -- I am a initial for those stations working me on 23 cm. I worked 29 stations in the DUBUS Contest and am now at initial #53. My future plans are to expand the dish from 12' to 14' and get my YD1336 cavity playing. Currently, I see 17.2 dB sun noise at SF=190.

YO2IS
Szigy writes that he has no interest in JT44 .It is sure a nice technical achievement, but certainly will not help us to get better EME traffic skills and knowledge. It also is a pity that now a days the number of EMEers NOT interested in swapping QSLs and photos (even via e-mail) is growing and the commercial interests are always pushing back the EME traffic. Being myself a "traditionalist" I have unsubscribe from the Moon-Net some months ago. I have now decided to not take anymore EME skeds and to abandon the QSL traffic as we still do not have the "outgoing QSL bureau" of our association! I always will be pleased to make EME contacts on random with my old EME friends and show their QSLs and pictures to my visitors.

ZS6AXT
Ivo has a bit of a late report because of an emergency -- Very poor participation in the Italian Contest plus some cable failures and a 6 m opening cut my score this year. My shorter moon window did not help either. On Saturday 18 May I started on 23 cm by working JA6AHB, SM3AKW, F2TU, G4CCH, IK2MMB, G3LTF, DF4PV, OZ6OL, SM6CKU, W2UHI, K9KFR, OZ4MM and W7BBM on the horizon. CWNR was IK3COJ. On Sunday I started on 13 cm by working JA4BLC and F2TU, then as I was fitting the CCTV camera to the dish, I did something to the 13 cm TX cable and I could not find the fault! So I went back to 23 cm and worked HB9SV and I0UGB for initial #180. Then I QSY'd to 6 cm and worked F2TU, but nil was heard from I6PNN, and back to 23 cm for IK3COJ - came back to my CQ, GM4ISM #181, W7SZ, SM2CEW and CWNR HB9BCD. This was quite a poor score with the exception of the 2 initials. I had good weather with the exception of some wind on Sunday afternoon. On Monday while lowering the dish elevation to remove the camera, the AZ drive chain slipped (it was quite stretched already) and dish went wild, probably damaging some cables. Quick single-handed temporary repair of the drive in the afternoon allowed the dish to be safely parked. Since then, we had a cold front passing, so no idea yet what else is damaged, but hope for not much damage and expect to be QRV in June.

K2UYH
I did not get in much EME operation during the May SW, because I was at Dayton on Saturday. I did meet some of the EME gang there, but I did not see as many as in the past. Tom, K2AH said that he and Marc, N2IQ left on Saturday morning. I was active on 1296 on Sunday, 19 May. There were a number of stations on looking for Italian EME Contest points. I QSO'd at 2135 G4CCH (559/439) and (55/55) on SSB, 2151 F2TU (55/55) on SSB, 2159 DF4PV (45/55) on SSB big signal, 2210 W7SZ (559/559) and 2240 W7GBI (559/559). It was good the hear Charlie active again. G4CCH told me that ON4QQ is now QRV on 23 cm, but I did not hear him on. I now have JT44 installed and am interested in skeds on 432 and 1296.
