2007 ARRL International EME Competition

From The Participants

G4CCH:
At times, the bottom 35 KHz of 23cm was crammed with stations, and some of them were VERY loud... like HB9SV, HB9BBD, K5SO, HB9Q, OZ4MM and OK1DFC.

SV3AAF:
Dear All,

I have been QRV for the most of my moon-time during ARRL EME contest ’07 on 70cm & 2m. Was happy to hear the bands alive although there were extended periods with the CQ callers receiving no replies, mostly during second leg.

I completed with the following stations working unassisted on CW mode:

144Mhz:
SV1BTR, IK3MAC, RN6BN, RA6DA, F1FLA, OK1MS, F0CXO, SP7DCS, LZ2US, F3VS, K9MRI, IK2DDR, OK1VVP, K9DX, YO2AMU, OZ1HNE, RU1AA, LA8YB, OK1KKD.

432Mhz:
DL9KR, HB9Q, K1FO, OH2PO, UA3PTW, I1NDP, K1RQG, OE5JFL, KL6M, SV1BTR, DF3RU, DL7APV, G4RGK, RW3PX, K0RZ, VK3UM, OZ4MM, JA6AHB, JA9BOH, SP6JLW, JJ1NNJ, G3LTF, DK3WG, FR5DN, YO2IS.

Conditions at this end:
Thankfully WX cooperated during the two weekends while some days before or after it could have spelt disaster with high winds and rain.

Equipment/antenna system worked seamlessly throughout the long hours of operation.
EME propagation was from good to excellent with some faraday and extra attenuation during second leg mostly effecting 2m while long libration periods made operation on 70cm more enjoyable both weekends.

Best Regards,

SV1BTR:

Here are my results for ARRL EME Competition 2007, Single Operator Multiband 50-1296MHz , ANALOG.
All QSOs in CW mode, all QSOs on Random (no passive / active internet use, no skeds, no external help).

Total: 152 stations, 157 QSOs
2m: 100 stations, 104 QSOs (4 dupe)
70cm: 52 stations, 53 QSOs (1 dupe)

I would like to take the opportunity and thank all the 2m & 70cm dedicated and occasional EME ops, regardless of mode. Those I worked and those not completed due to partial copy or merely qrz. Know that I tried hard and hope next time I will not miss you. Especially I would like to thank the 2m new to EME, newcomers to CW and QRP mixed operators. It has been a real pleasure to me to work again down to single yagi and 250w stations on random, as well as being the 1st or 2nd ever CW QSO to previously only digital, ops. The EME old timers always wisely said for CW: ''if you can't hear them you can't work them''. Therefore copying and working QRP stations in CQ EME has been once more a real pleasure to me, since  my 2m array has similar gain to 4*11m long yagis.

Activity on 70cm was good. I am glad because this band has long time lasting, dedicated, excellent CW ops.

Conditions:
WX was perfect. I was vy lucky in this respect. In 2nd leg, propagation conditions on 2m featured deep QSB in all 3 passes for both polarities. On 70cm there were periods with good signals without problems of Faraday, and extended periods with signals in both polarities being steady, but down by 2db.Echoes on both bands indicated the same findings as above, all over the weekend.

Murphy visits 2nd leg:
I faced problems with 70cm new azimuth, pointing errors (fortunately there was full moon so i tracked it by going out of the shack every now and then:-) ) On both bands I had lesser elevation errors this time due to some improvements, of up to 2.5 degrees which varied non-stop according to the readout wishes...not the best in narrow main lobe, arrays. On 70cm continuous PA flashovers forced me to decrease power by 1.5db to be able to remain QRV.

But as they say....no pain, no gain!

Hi there LUNAticks...I was QRV a lot during December and as well during the secondpart of contest for some hours as well and found condition very nice Saturday. Sunday it was very noisy here, and lots of QSB on the sign! Was happy for a lot of new Initials and as well 2 fine CW QSOs... (sorry Jimmy, did call you 2x30min and maximum was a QRZ from you...)Did work as follows in Nov (only C QSOs - the list of NC is much longer, hi):

K7XQ:
I had a great time operating all three weekends of the contest. Conditions were extremely unusual on 144 MHz where signals would very from 20 dB out of the noise, even moving the S meter at times, to NIL in a matter of seconds but with no faraday changes. This was why I didn’t do too well on 144 but 1296 was stable as a rock with unusually stronger signals. I did much better on 2304 after the contest after I found a blown/shorted regulator in the preamp causing a overvoltage condition to the front end device creating excessive gain and a very high noise figure.

I will be submitting as single operator, CW only, random unassisted, mixed band entry ( all call signs included below ).
Any assisted contacts will not be included in the ARRL submitted log but are located on my webpage logbook. 

First Contest Weekend:  
2304: OK1MS#, KL6M# 

Second Contest weekend: 
144: F3VS, IK3MAC, OK1MS# 
1296; SM4DHN#, K9SLQ, N9JIM, K4QI#, OK1DFC, G3LTF, LA9NEA, HB9Q, OZ6OL, RW1AW, K1JT, G4CCH, N9JIM, WA6PY
JA4BLC#, JA6CZD#, JR4AEP#, OK1CA, OE5JFL#, RW1AW#, IW2FZR#, OZ4MM, DL4MEA#, OH2DG#, AL7RT#, N0OY# 

Third Contest Weekend: 
432: G3LTF# 
1296: DF3RU#, K2DH#, K5SO, K5JL, VK3UM#, VE6TA#, VK4AFL#, W2DRZ#, JR4ZZS#, VA7MM# 

The 432 array is only partially built as 2 X 9 W.L. XPOL @ 20 dBd total gain but was pleased that the GS35b amp stayed stable with very little power drift on this band at a full 1500 watts. 

Next contest will alternate the bands more often and try not to stay on any one band too long. Could have picked up more on 144 although as K6PF described recently, it is not as populated on CW like it used to be. 

Congrats to K2TXB on his only contact during the contest :)))

SP7DCS:

Hello!

During the first weekend I was QRV only on 2m and 23cm, but during second weekend I added also 70cm band. I was QRV on CW random only, without assistance, internet etc... and I managed to work 98qsos (6 duplicates).In my opinion conditions were good on all bands, even for single polarized stations. On 2m I used big system and QRO so I had good echo almost all the time,up to 25dB over the noise.

On 70cm I was totally QRP, but I was very happy to put 7 big gun stations into my log. 23cm was nice surprise once again, even with so small station I was able to hear a lot - band was sometimes like on HF.

Unfortunately many stations were not able to hear my small signal, so maybe I just need to increase my power before next time. So, I was my first contest on 3 bands and I very liked it. Multiband work is totally different thing and is very interesting.

During first weekend I spent about half of QRV time on 2m and on 23cm. During second, I was only short time QRV on 2m and I decided to concentrate on 23cm and 70cm. Of course it decreased my total QSO count as I am QRP on those bands, but I had great time and a lot of fun!

The only exception from random work was sked with P43L on 23cm. Unfortunately I did not have luck. Pity, because I could hear them ok the day before. Anyway congrats for great expedition! Congratulations goes also to OZ1HNE and LA8YB for getting back to 2m eme!!!

OZ1HNE:
Hi EME'ers-

I was QRV in the second part of the ARRL EME contest on 144 MHz CW and worked 27 stations in about eight hours. I was calling CQ all the time just to test and play with the new antenna. Weather was very bad with rain and strong wind, so I had to close down. Thanks to all for the QSO's and sorry for the stations I not could dig out of the noise. I am very glad to be back on EME and I will be QRV on CW in the future.

Here are the stations I worked:

SM2CEW:
Pretty much everything has been either not possible to use, or has been running in "limp mode" during this years ARRL contest. During the first leg we had very strong winds that prevented operation except for a few hours when I could be QRV on 144 MHz. This resulted in 11 contacts.

The second leg was no different.. The 144 MHz array was totally iced up, and SWR very high -> "unusable" My dish elevation was frozen solid in the park position, and while trying to get it going on Friday I managed to damage the elevation mount. Early Sunday morning I could get the dish going, but only at very limited elevation angles. The problem was not the snow, but the thick layer of ice under the snow.

http://www.sm2cew.com/sm2cew_dish_nov_07.jpg

At 0630 GMT on Sunday I heard P43L working N2UO on 1296 MHz, and Al (K2UYH, guest at P43L) had a really good signal. Unfortunately P43L had to stop operation right then and there as torrential rain was making the /portable operation under a tarp impossible.

I worked 18 stations in an hour and a half on 23cm, new initial was AL7RT. On 432 managed to get on for an hour as the moon came above the trees on moonrise, and worked 8 stations. Conditions on 432 sounded really good, despite heavy aurora. Due to the earlier problems, my elevation drive jammed at 29 deg elevation, so I had to stop with many hours of good moon still available on Sunday evening.

Sorry for missing those treasured CW QSO's with a lot of you guys, but this is life at the Arctic circle. 37 QSO's only in this years contest, snow and ice last weekend, and strong winds that kept me off for most of the time during the first leg.

But best of all, all QSO's were done on CW, without the help of loggers...hi!

The new rules that allow chat board communications and self spotting by using Internet communications really bother me. This has absolutely no place in a radio contest. As the rules were written this time, the assisted category was supposed to be for small stations, and newcomers to EME. But the outcome was, that all station, big or small, were doing the same thing. They constantly self spotted, and used the internet chatboards to talk themselves through their so called contest QSO's.

Because of this, I choose not to submit a contest log this year, except for a checklog to help the organizers determine that QSO's listed with me were ok. A contest really is about skills and tactics on the air, not how many stations one can line up via internet chatboards. That looks more like using a telephone listing to make contact with your friends.

Having operated every year in this fine event since 1985, my suggestions to the organizers are the following:

- do not mix modes, run separate weekends for analog/digital.

- do not allow self spotting, or chatboard communications during the event.

- allow operators to enter different categories, depending on how they desire to do so, for instance enter Single band/Single Op on 432, 1296 and 2304 MHz respectively.

- please find a contest format that will survive >12 months, and not be changed every year because some people think it is too difficult to make random contacts on the radio!

As I know it, the ARRL were the first to organize an EME contest, handing out awards to everyone who made at least one EME-contact. This has been a TREMENDOUS source of inspiration through the years. It would be terribly sad to see good moonbouncers let the opportunity to compete and have

EME fun pass them by, just because the rules reflect more on internet-based communications rather than radio communications.

WA6PY:
This year it was again very good activity on 3, 13 and 23 cm. Great  signals. On 70 cm I was using dual dipole feed extended with 8 WL of directors. This antenna is like cross yagi, but noise temperature is quite high. I was surprised to hear echoes with this antenna. This was  probably thanks to the perigee. I managed to make 11 QSO on this band.

SM5LE:
I did focal adjustments just before ARRL contest and it paid off. I did better that the contest before.

73 Sven SM5LE

DL5MAE:
I am not surprised about too low number of input. ARRL EME Contest rules just became too complicated and too much internet orientated. This is not what radio contesters looking for.

And there are still categories completely forgotten (i.e. single OP, assisted, analog ).

blog.sm2cew.com may give you more reasons for the lack of contest logs and comments from big guns.

OZ1HNE:

I was active in the ARRL EME contest 2007 just like the last 18 years, but this time I decide not to send the log because of the very unfair rules comparing digital and CW. In my view Digital and CW is two very different modes and have to be split up like in the European EME contest. I really hope ARRL will listen and split up Digital and CW in two separate modes, and it will again be interesting to send in the log and we will again enjoy to work the ARRL EME contest.

Best 73, OZ1HNE Jorgen.

HB9Q:
The main target at HB9Q is to work QRPP stations on 144, 432 and 1296MHz.We enjoy giving newcomers a chance to work EME. For many of them it is their very first experience and the first QSO off the moon. Many got started that way and are now QRV with bigger antennas and/or more power. Several of them start to become QRV on CW as well. In an effort to help newcomers we chose to use self-spotting on the loggers. The effort did pay-out well, we worked on 432 14 stations (for 7 it was their very 1st EME QSO) with 1 yagi and 100W or less. Some of the smaller ones are VE2DSB (1x22y 30W), IT9CJC (1x13y 40W), ZS6TW (50W into a 3ft long yagi) and WD6DBM (1x18y 33W).

K1JT:
The EME stations of K1JT and K2UYH, just six miles apart, were combined into a multi-operator effort under the competition's "neighborhood provision."  We used the callsign K1JT.  Our operating strategy aimed to take best advantage of prevailing activity patterns on the 144, 432, 1296, and 2304 MHz bands, using both CW and JT65.  We used no internet or other liaison assistance during the contest.

Our team grew progressively through the three contest weekends, starting with the home-station operators Joe and Al in September.  We operated on the 2.3 GHz band using the K2UYH 8.5 m dish, with circular polarization, an 80 Watt solid state amplifier, and separate IF radios covering the 2304 and 2320 MHz band segments simultaneously.  All operation during this weekend was on CW.

In October Al operated his station on 432 and 1296 MHz, this time aided by KC2TA.  Feeds on the 8.5 m dish provided rotatable linear polarization on 432 and circular on 1296 MHz; transmitter power was 1000W and 500 W, respectively. We used mostly CW, but did make one digital QSO on 1296 MHz.

Meanwhile Joe was operating the K1JT station on 144 MHz. His station hardware includes four dual-polarization 14-element yagis with separate receive preamplifiers for the two polarizations.  The two resulting signals are converted to baseband and then digitized under control of the Linrad software package.  For CW operation, Linrad was configured to display a 60 kHz range on a slow, high-sensitivity waterfall.  Tuning a CW signal is a point-and click operation on the waterfall.  A few additional clicks serve to match the received linear polarization angle to that of the incoming signal, and once the received polarization angle is known, the best transmit polarization (H or V) is determined.  For JT65 operation a full 90 kHz passband is sent in digital form from Linrad to a second software program, MAP65.  This program searches a specified frequency range for JT65 signals, optimizes the received polarization angles separately for each one, and decodes them.  We normally set the range to 144.100--144.160 MHz (or 144.070--144.130 when the Moon was up in Japan).  Selection of a particular EME signal is again a point-and-click operation, and the program advises the operator on the optimum Tx polarization angle.  On 144 MHz we operated almost exclusively in search-and-pounce mode, because with this hardware/software setup it is easy to find stations calling CQ or to tail-end on other QSOs in both CW and JT65 modes.  The transmitter at K1JT provides about 1100 W to the antenna.

In the November contest weekend Al operated as P43L, putting Aruba on the moon for a few days on both 432 and 1296 MHz while enjoying the Caribbean sunshine.  This time the K2UYH station was manned by K2LNS and K1DS, and again most of the effort on these bands was on CW.  However, when the going got slow a number of JT65 QSOs were made as well. Operations on 144 MHz were aided this time by N4HY and AB2BK.  Both JT65 and CW were used on 144, according to the perceived activity levels in each mode.

WD5AGO:
We were on 13cm with our 8 foot extended to 9ft dish and had our best score ever on 13cm EME.  Heard over 25 stations and worked most of them, students had interest when it is speaker copy!

The following month we designed a new scalar feed for 23cm and put it in with only 100watts.  Worked 10 stations but heard 30!  As this was just for fun and not to compete we did not turn a log in for this band, maybe next year.

N6CW:
My first EME contest since 1988. Conditions were good during both weekends for me. I entered mixed mode and worked 8 CW and 81 digital contacts with my modest 4x9 antenna system. While JT65B is an easy way to get on EME, I find it to be a very frustrating contest mode. It can be a mighty long minute to find out is someone has answered you or someone else.
