to the final report award event 2025C

Editorial Status: 17.04.2025

RESULTS from March 5, 2025 March 12th, 2025 March 19th, 2025 March 26th, 2025 Receiving is possible with (almost) every TRX! Mirko’s DIY 630m project

In the month of March there is a chance to reach a new band point on Wednesdays. DL2025E will be heard and operated on 630 meters. On Wednesdays, March 5th, 12th, 19th and 26th, 2025, Helmut (DL6KWN) will be using the call sign DL2025E promptly at 20:00 UTC for at least 10 minutes (see also NOTE below) on 630 meters.

(to check, watch the ON-AIR spot on this website or on QRZ.com!)

Helmut – who is also the Chief OP of DL0MCM/Traditionsschiff from the traditional ship “Frieden” in Rostock (JO64bd)- will be using a ship radio distress transmitter (500 kHz is the calling and distress frequency) on  473,7 kHz .

TX: ship radio emergency transmitter SNS 577, built in 1970

RX: Restored emergency receiver Dabendorf, Audion / 1-V-2 with battery tubes of the D series “… with amazing sensitivity”. For comparison, an IC-7410.
ANT: original ship antenna of the MS “Dresden” = L-antenna in 2-wire design at about 32 m above water. Distance between the horizontal wires about 4-5 m. Horizontal length about 30 m, the vertical part runs slightly diagonally and is about 17 m long. At the lower end, the two wires are brought together before entering the antenna shaft at a height of about 19 m. (Info DL6KWN)

This 630 meters offer was already well received at the 100FK radio event. It is exciting to achieve range in this lower medium wave range with the simplest technical equipment. 630 m is also particularly attractive in the context of 2025C, because the award program is based on the operators’ enthusiasm for experimentation. Particular attention is paid to the antenna. (λ/2 = 300 m!)

On the subject of 630 m, a few DIY ideas for antenna, converter and TX: (1) (2) (3)

   

Most HF-TRXs can be used as receivers, as they usually start at 30 kHz on the receiver side. Plus a simple L-antenna + charging coil…!? We look forward to hearing about your experiences!

630 m antenna      and Mirko’s 630m DIY projekt !

It can be easier (receiving)! My optimistic SELF-TEST: RX of my Kenwood TS480 + 80 m loop at 8 m height = SM4WII/B with S4 QSB on 476 kHz /QRB 726 km … Please tune to a low and deep QSB and listen longer!  630 m currently in the cluster 

Every call is welcome (in 2024 at 100FK there were 6 call signs) and especially audio (SWL) reports are expressly desired! We are happy to receive any experience report – on 630 m tinkering as well as an audio recording of the DL2025E you have heard. Please send an email to or to Helmut DL6KWN directly (see QRZ.com). By submitting a report, permission for publication is assumed unless explicitly stated otherwise. Thank you.

NOTE: There are probably not many stations on this somewhat exotic band, so the call will be aborted after 10 minutes of unsuccessful CQ calls (after the last QSO).

DARC OV S54 with DL2025C at CTL Junior / Chemnitz Linux Days (CLT)

There were certainly not only a rich program for LINUX fans on the weekend of March 22 and 23, 2025 at the Chemnitz University of Technology. This year, too, there were an extensive program for children and young people. This included the now traditional electronics soldering workshop, which was supervised and accompanied by members of the Chemnitz OV S54.

---

NOTE: When operating radio (SSB/CW/FT8, + QO100 etc.) in Fieldday mode, there may be slight delays in log upload! We ask that you take this into account when calculating your award points. Thank you for your understanding.

DAY 1 

Big crowds like every year	Lively discussions at the DL2025C booth
Many discussions about digital media	Amazement and admiration for the radio connections via satellite QO100
The soldering and crafting workshop was once again prepared in an exemplary manner	… and the OPs of the OV S54 are always there as sought-after helpers

This year, too, a wide range of activities delighted children and young people, especially the now traditional crafting and soldering workshop as part of the “CLT Junior” campaign. Members of the Chemnitz OV S54 club, who were enthusiastically supported and supervised, participated.

At the same time, the special call sign DL2025C was also “on air.” Given the high level of noise generated by the numerous interested parties, including several radio amateurs, the focus was on digital modes. This allowed for a few questions to be answered “in passing.”

There was also great interest in the QO 100 station. Several QSOs were also conducted in CW. This often aroused surprise among visitors (usually with “digital DNA” 🙂) “What, analog? …that such a thing still exists!”

Amazement and respect for an interesting hobby with great diversity. / Steffen, DM6WAN for OV S54

It is always wonderful to learn how amateur radio is an important part of the quality of life for people with disabilities, impairments or limited mobility and/or can counteract loneliness.

Lothar, DL9JBN, is a very successful whitesticker on the DL2025C operating team.

Now, some people might be wondering: how do the QSOs from a blind operator get into the log?

A simple but effective technological process has been developed for this. There’s close collaboration with me as the team leader. First, I initiate the online registration on the server. Then Lothar is left to his own devices. As agreed, and preferably in FM on 70cm/2m.

So, during his last mission on March 17, 2025, 66 contacts were logged via the relevant repeaters in just a few hours. The term “log” isn’t quite right here. After each QSO, Lothar records the data on tape… and then it’s off to the next QSO.

Then comes part 2 – the “log conversion.” Another call to me signals the end of the activity, after which I first log off the server. But the main focus of our usually lengthy 🙂 phone call is the audio conversion. Lothar plays the tape piece by piece, and I take over the entry of each QSO into the log program, including the exact time and QRG. Then two more upload clicks, and Lothar’s QSOs are on the award server – and that’s it.

P.S.: Lothar is now well into his 80 years.

Ham radio helps combat loneliness and exclusion. The all-important social contact with like-minded people is almost always guaranteed – and this is done on a global scale, in a spirit of friendship and mutual respect. If needed, you can also access topic-oriented ham radio communities where you can pursue specific topics and find help and support.

The air raids on Chemnitz during the Second World War caused severe damage to the Saxon industrial city of Chemnitz. From February 6 to April 11, 1945, units of the Royal Air Force (RAF) and United States Army Air Forces (USAAF) flew a total of ten air raids on the city. One of the worst bombings took place on the night of March 5 to 6, 1945 – exactly 80 years ago.

An Anglo-American “double strike”. In the morning, the USAAF flew its usual daytime raid from 9:45 a.m. to 12:10 p.m. with 233 B-17s, which dropped 563 tons of bombs, and long-range escort fighters. The main target, Hilbersdorf station, was again not hit, but much further destruction was caused in the city.

In the evening, the sirens wailed from 8:30 p.m. The British RAF and the Canadian RCAF attacked, a first wave from 8:37 p.m. to 9:08 p.m., the second wave from 10:30 p.m. until after midnight. The city was very well lit by “Christmas trees”. 683 heavy four-engine bombers of the Halifax and Lancaster types initially dropped 413 mine bombs (around 800 tons), then 859 tons of incendiary bombs and finally 1,112 tons of high-explosive bombs. 22 aircraft were lost. 2,105 people died in Chemnitz that night alone. The city was lit up glowing red, “the firestorm was bad, but not as bad as in Dresden”. Even two days later, not all of the fires had been extinguished. Of 117,000 homes, 42,000 were destroyed. 75% of the city area and 140 km of front-line buildings lay “in ruins”. The surviving population fled to the surrounding area. 167 factories, 84 public buildings and numerous cultural buildings in the city area were completely destroyed; the city center alone was 80% destroyed, which is a quarter of the total housing stock.

Allied aerial reconnaissance recorded Chemnitz as “another dead city.”

As in the previous year, the Chemnitz DARC local association S54 organized such a workshop for and with children and young people. In the year of the European Capital of Culture 2025, this workshop was again very well received.

Under the leadership of Carsten (DGØJCG as well as SES-OP of DL2025C), 5 other OMs from the OV (Jens, DB5JH; Jürgen, DL1JHQ; Hartmut, DH9KFC; Wolfgang, DL5WSC and Steffen, DM6WAN) were happy to take over the supervision.

Special praise goes to Carsten, who, in addition to his commitment as OP at DL2025C, organized this workshop perfectly.

For a summary report:

We have received some sad news. Rainer, DL3JRA, op in the DL2025C team, unfortunately passed away on January 21st while on holiday in Egypt.

He had been looking forward to the 2025C event so much and wanted to get back into his favorite CW mode after his vacation. In the past ham radio events, Rainer was one of the most active CW operators. He particularly enjoyed being out and about on 80 and 40 m in the morning hours.

For all of us who knew and appreciated Rainer personally, this news was a shock. Our thoughts are with his family and all friends and acquaintances in these difficult times.

R.I.P. dear Rainer
