Only QRV on 70/23 without elevation. Frank, NC1I with good signal on Saturday and Sunday :-) Tnx for the opportunity. 73 Detlef |
DL0SHF |
Thanks to all for being on the moon. And sorry for all, I could not work, because my time was limited. Worked CW and Q65 on 23cms. Things did not run always as expected, but I could make a good number of contacts. 73 de Christoph DF9CY for DL0SHF |

first part: PA was broken. only 50w at the feedpoint of an 8 x 11ele array. Missed many QSOs because QRP. I'll be back :-) November part: PA working again. most contacts done with 400w only. I even worked a single yagi station. tnx DF7VX for help with PA. the 8x11element array was given to me from DL7APV (sk) 4 years ago. It is the prototype of his big 128 x 11 ele array. |

Few time and a lot of local noise only allowed me a single QSO. Short test but it was fun. I hope to complete more contacts in the next contest. Greetings EA3BZ |

during this first part, activity was high from Europe with good conditions with low spreading. The second party activity in september was amazing. In memory of Jean Jacques F1EHN SK RIP my friend |

I am quite happy with the idea of using QRA locators (grids) as a multiplier but you should have made it clearer at the outset that it was not required to be part of a CW QSO. I suspect that the late clarification reduced the CW activity. |

Only QRV for the second weekend, Preamp died on the last Moon pass on Sunday. Station: 8 x 27 el DJ9BV Open wire feed lines PA = 2 x 3CX800A5 700w MGF1302 Preamp |

I took part in the contest only around three hours a day. Since my parabolic dish is on my balcony on the second floor, I have only a limited view of the moon ! |

It's my 4th Arrl eme contest on 23 cm. I made 137 qsos, 27 of them on cw. I found a very good conditions and a good activity. As written on my log i try to suggest to permit twice qsos with same station. One on digi and the other on analogue (ssb/cw). This for help to those stations that use only analogue modes to meet more stations. Anyway, i'm quite sure that this was my best result, since I started on 23 cm on may 2021. Many thanks to Arrl guys and to all worked stations from my 3.7 m dish. 73' Francesco IK2DDR |

As usual the EME event with the highest level of activity. In consideration that finally Q65-30B is widely more used by on 23 cm it should be considered to reduce the contest time to ONE week end only. |
K1WHS |
It has been awhile since I submitted an EME Contest score. My first entry was in the #1 EME Contest back in the mid 70's and I had 19 contacts on CW, all on 144 MHz. This time, I split my time on 222 and 23 CM. Times sure have changed! |

Thanks for accepting the ADIF files! That's a huge improvement. I missed the first 2 days so I needed to catch up for the second two. About 70% of my contacts were obtained calling Q65-30B. The remaining were found my observing the logger and monitoring QMAP. I see the latest QMAP (which decodes 60C and 30b) causes IC-9700 disconnects, especially when several decodes come in at once. I went back to the prior version which works fine but only decodes 60C. Many thanks to G3LTF and SM2CEW for my 2 CW contacts. During the two days I was able to achieve 85 unique QSOs. Thanks again! |

October was good for the eme contest but November was terrible for Michigan. Heavy overcast skies was not good for the contest. This was my first time doing the contest, made my 1st eme contact on 9/2022 with 2 antenna and 160 watts. It has now grown to 4x9 H frame and 1000 watts.

Strong 6m EME activity fueled great fun. Highlights: 1) Bob ZL1RS called with 1 x 3-element yagi on a short mast and we completed. 2) Matt W3UUM and I completed a QSO of special historical significance. Ours was the first complete 6m EME QSO by the Swan 6B pair of 3-500Zs power amplifier used to start the first 6m EME QSO 30 July, 1972. That first 6m EME QSO between teams: W5SXD/5 and K5WVX working WA5HNK and W5WAX/5 required two power amplifiers to complete because the Swan 6B running 700w CW failed during the 1972 QSO try and had to be replaced by a Heathkit SB-200 which completed the first 6m EME QSO. The November 2024 ARRL EME QSO between W3UUM and KJ9I was the first 6m EME QSO completion for this same Swan 6B amplifier Matt de-rated to 300w running Q65-60A 100% duty cycle mode. 3) First EME QSOs for G5SIX and JA3EGE, 1st 6m EME QSO for N2EME. 4) Traveling operator included Bo OX3LX by OZ1DJJ using a 1 x 4 element yagi on balcony railing. 5) One operator at two DXCCs featured Lance W7GJ who operated the November contest weekend from Montana, USA and the October weekend as ZD9GJ during his 6m EME DXpedition from Tristan da Cunha: his was quite the ‘roving adventure !’ |

really excellent condx with "super moon" on the Novemeber weekend. May stations to work. 23cm is the best band for EME by far. Dan N5TM |
OK1TEH |
I originally planned to run the ARRL EME Contest 2024 with a new antenna system, unfortunately work duties didn't allow me to do that and so I decided to run the contest from my home QTH in noisy Prague on 70cm with my old single 23el DK7ZB from OK2BJL workshop, which has a boom length of 5.7m. The intention was to beat my personal record of 34 QSOs (Q65B) for both legs and learn some new Q65 tricks.. In the first round I worked with: UA3PTW, DL1VPL #, PA3DZL, W5LUA, OZ9AAR#, VK2CMP, HB9Q, DF3RU, GD0TEP, K4EME, PA2V, W5ZN #, EA5CJ, VK4EME, PA2CHR, SM4GGC, ON7EQ. In the second leg I added: NC1I, K5N (ex K5QE), KD2LGX, PA6Y (PA2V), DK3WG, W6TCP#, K1OR#, OM4EX#, OT7K (ON4AOI), G4RGK, VE6TA, DM9EE, N1AV, YL2GD, OE3JPC, UT5DL, PA3CMC#(1Y-1Y! ), GD0TEP (dupe), SM3LBN #, DL8DAU, SP2WRH #, DL5BBH #, 7K3LGC #. Total 39 QSOs. The extra bonus was FB 70cm CW tropo QSO with Peter, G3LTF just 2h before the start of the 2nd leg. I'm personally very happy with the result, the second half was much better in terms of Faraday's lock and I thought the activity on the band was better too. I was very pleasantly surprised by the easy random QSO with PA3CMC, who used only 1x41el M2 15WLA(!), which is only the second 1Y-1Y QSO ever on 70 for me. After a big struggle I also managed to make a rare QSO to JA with 7K3LGC. Unfortunately there were a few more stations on the band that saw me, but it was mostly when the Moon was in low elevation and the band was full of birdies.. For example, I missed S56P, DL5FN, SM7SJR, S51ZO.. I was also sorry that I didn't catch Jan, DL9KR on the band, it's a great pity that CW traffic was down, I think in contest rules there should add bonus points for these CW contacts. For those interested in QRP EME, I would like to give a few more hints about the possibility of improving RX. For reception I used old FT847 from 1998 which has a number of modifications including separate RX/TX, improved RX path, ALC mod and more. From the antenna dipole I use a 3m long Andrex CellFlex 1/2". In the box I use a CZX3500 relay with LNA with ATF-54143 built by OK1VPZ (selected from 6 pieces by it's robustness of local nearby TV BC tower) with measured noise figure of around 0.4dB. For signal processing, I primarily use an old 2008 ThinkPad R500 Core2Duo with 8GB RAM with Windows 7-64b, integrated sound card and WSJT-X v 2.5.4. This configuration is about the HW minimum that can be used in a reasonable time for decoding, however, it is necessary to limit the filter width to 500Hz, as this bandwidth is directly related to computational demand (FLOPS). To increase speeds during the contest I experimented with a Creative Sound-Blaster X-FI USB sound card connected to the FT847 DATA port and further connected to a Thinkpad X220 I7 16 GB RAM Win7 XP running with the latest version of WSJT-X v.2.7.1. This second computer allowed me to decode the full 2.4KHz bandwidth of the SSB filter in a reasonable time. Understandably, I was most interested in how reception would vary when decoding the weakest signals at around -30dB using a 100 or 20 Hz filter. I have to report that in the vast majority of cases the signals were decoded with the same strength and only about twice I found out that the external USB soundcard was able to decode the signal, while this did not happen on the older Thinkpad R500. This feature helped me especially with borderline weak signals QSOs with N1AV and 7K3LGC. Basically, the most difficult part is finding the exact location of the station (WSJT10 SpecJT is missed), then it's just about the apply of narrow filter. Unfortunately, on 70cm it's common for many stations not to use TRX with the LO locked to GPSDO, so even if the oscillators are stable and the stations are using CFOM, it's no guarantee that the signal will be exactly where on the waterfall you're looking for. I think the easier situation is on 23cm, where GPSDO lock is standard. It is a great pity that the latest version of WSJT-X isn't available as a simple to install APT-GET package for Debian/Ubuntu Linux, I think it has helped bring many older computers back to life.. Finally, I would like to thank everyone who called me even though the connection failed and if health and time permits I will look forward to the next contest.. |

This was the first time I had ever participated in an ARRL EME contest, so it was an uncertain undertaking for me and I didn't know what to expect. I had agreed with Zdenek OK1DFC beforehand that he would work the 23cm band in the first part and I would work the 70cm band in the second, in November, we'll switch. The purpose of the agreement was to eliminate mutual QRM, our antennas are less than 5km apart. Before the start of the October leg I made a QSO with the 7P8Z expedition, but then I was tired, didn't want to wait for the contest to start at 00:00 UTC and I went to sleep. I started the contest at about 6:00 am and it turned out to be going pretty well, with several stations calling me occasionally at the same time, EU and US. I had a family event scheduled during the day so I couldn't make up the sleep supply for the second night, which I also slept through, just bad time management. I made a total of 81 contacts in the first part, one CW, one JT65 and the rest Q65 in 18hrs of operation out of about 29 possible, when the moon was above the horizon, the rest I slept. After the contest, I was wondering if the my result was good, or if it was not worth much, I just lacked experience. Total for the first part 32 inits: KD2LGX, K5N, K7ATN, W7TZ, W4NH, N5UC, UB4UAA, YL2GD, JR0WFY, OH4LA, DL5BBH, S56P, PA6Y, SM6CEN, JQ3JWF, JE2UFF, RJ3DC, DM9EE, S51LF, JG2XWH, KB0Z, WA3RGQ, GM8JBJ, N9LHS, PA3CMC, SM7SJR, IZ3ATX, IZ4FUA, F1RJ, IZ6MVK, S51WX, G6HKS. Later I realized that the result was not bad and that it would be worth trying the second part. I agreed with Zdeněk OK1DFC that I will resign from 23cm and we will keep the same period in the 70cm band. In the meantime, since I had forgotten who I already had and who I didn't, for the second part I prepared a list of stations I already had from the first round, used paper version, sorted by the last letter of the call, like in the old days, and I wrote the new stations in a different colour. The opposing stations probably didn't do that, because my CQ in the second part matched a lot of stations I already had from the first round, but it didn't matter. In the second part I managed to make contact with 31 new stations, 15 of them were initials PE1ITR, DL5DAW, K3SK, VE4MA, K1OR, OK6TW, OZ1SKY, GM0ICF, SQ9MYQ, G0JDL, DL1SUZ, DL6KAI, VE6TA, N7GP, F2CT Thank you all for the QSOs and I look forward to hearing from you next time. |

This was my first participation in the EME contest, and what a thrill ! I made two QSO's with only 35 W, straight out of my ICOM 7100 into a 20 element Yagi. Never thought that would be possible. An unforgettable event and what an experience. And a big thank you to Joe, K1JT and his dev team for bringing the Q65-60B mode. 73's Erik ON4PB |

Ran a sked with Paul NO0T op at K0PRT. Paul and I go way back to High School days so I always try to work him. Luckily they had repaired the dish drive chain, and were QRV. We ran Q65 and I started seeing them when the moon was about 3 degrees, but we didn't complete until it was at 1.3 degrees. I was pointed west into the Radar from YYZ as well but we managed the 2 way! The automatic doppler control worked FB this year. Station here K4/ Q5 driving a 120 watt SSPA and 70 ft of 7/8 heliax to a 43 ele loop yagi at 65 feet no elevation/no preamp. 73 Dana VE3DS |

Was great fun. Worked one new station and many old friends. Hoping that i provided VK in the logs for a few stations. My 10G system needs to be moved from MR to MS as my house is in the way. 73 to all |

Another Fun EME Contest! Murphy only struck a few times requiring several computer reboots and the loss of the Vertical side of my 2m cross pole system. The signals on 1296 were amazingly strong and surprising not to much QRN on 2M this year. On 1296 using a 2.3M HRO dish with patch feed ( 200W) with limited sky due to trees and houses. On 2M running a KW in a 4xp9 with adaptive pol and an IQ+. I was also part of the W2ZQ DVRA team operating from the club station, so my home activities was limited to when I was not at W2ZQ or sleeping. See you all next year. |

The equipment used is all standard amateur equipment (IC-9700, BEKO linear, RFHamDesign dish, etc.) but it is technically owned by the university (NC State University). |

This year I deceided on a single band - 432 entry. Moslty S&P with a target of 50 QSO. Due to trees I have to wait to 20 deg of elevation so I loose a bit of prime EU moon time. Thanks for the Q's ! |
WB1BQE |
My first EME Contest - With just 2 Yagi's and severely handicapped by the 50 watt limitation, every QSO is a major triumph! I'm greatly appreciative of the super stations whose investments and friendly patience allow folks like me to participate! --Al WB1BQE |

My primary activity that weekend was to work as many stations on 6m as possible via EME and terrestrial. Since that weekend was the best terrestrial propagation of the DXpedition, and I had already worked 173 stations on 6m EME, I was concentrating on new contacts rather than duplicate EME contacts for contest credit. |
