#CQWW assisted and unassisted logs.

#cqwwcw #cqwwssb #hamradio #radiosport

Evolution of the percentage of run QSOs in #CQWW, 2005 to 2025.

Says quite a lot about the state of things, doesn't it?

#cqwwcw #cqwwssb #hamradio #radiosport

These are probably better indicators of long-term activity than the raw number of logs submitted for #CQWW.

#hamchallenge week 3: Understand how your antenna works. 🧵

Let's check out the lowband vertical antenna I built before #CQWW in November. It is 16.5m long, built with an 18m Spiderbeam mast minus the top element. About 18m of wire are coiled up on it (for stability), and it is tuned at the feed point with a CG3000 automatic tuner. There are 12 ground radials with an average length of 10m below it. When I built it and laid out the radials, I noticed that the feed point impedance stayed at about 37 Ohm at the resonant frequency of ~ 4.1 MHz any more after 12 radials, so I left it like that.

In the middle of the #CQWW contest, my SO2R Mini+ started to generate illegible Morse code. I didn't have the nerve to debug this during the contest, so I continued with a changed setup. Today I finally found some time to analyze the problem. Turns out something went wrong with the K3NG keyer firmware; the dots were normal but the dashes were almost infinitely short (1st picture). Re-flashing the Arduino and even (or so I though) deleting the EEPROM didn't fix this. However, after I resetted the keyer by holding both dot and dash paddle held down, everything was back to normal. This confuses me; I wish I could have understood what setting was corrupted, but at least it works again and I know how to fix it next time. This also sort of fulfills the @hamchallenge challenge for week 45 🙂
#HC45S

Down nearly 800 QSOs from last year's #cqwwcw contest. All the runs here were thin, until the last hour or so of the contest on 10m. Like almost every contest this year, down around 30% from last year: the solar peak is definitely over.

I worked my first #cqww DX in #CW this weekend. It was very exciting to work so many new to me countries.
I worked 267 contacts with stations from 6 continents.
It is stunning to see how far one can reach with 100w and CW.

#amateurRadio #hamRadio #cqwwdx #cqwwcw #contest

Gave the #qrp_labs #QMXPlus a good workout in #CQWW CW. Our Multi OP at G5O was cancelled short notice so I put up a random length Inverted Vee on Saturday afternoon. Missed Sunday morning as well so mostly worked to the west.

My #cqww #hamradio weekend: 1127 CW contacts to 115 countries, claimed score 870,928 in SO-LP (A).

N6MJ on the Canary Islands set a new world record with 12708 contacts in SO-HP, followed by KL9A on Madeira with 11343 contacts. It was fun to watch the online scoreboard.

Its #cqww time, qrv with DF7A as multi/2 #hamr #contest

Antenna setup at SO5CW for #CQWW done! #hamradio

Arrived at the SO5CW QTH for #CQWW. I hoped I could concentrate on setting up antennas today, but it looks like I need to do some plumbing, too. Argh! 😠 #hamradio

We now have more than 2500 registered users on the #DXCluster (DXspider) node DA0BCC-7 of the Bavarian Contest Club, (telnet://dx.da0bcc.de:7300) which I am the SysOp for. Typical daily connected user count is in the range of 70 (early morning UTC) to 250 (evenings), but I am sure next weekend during #CQWW we will see mor than that. Let's hope the cluster network and especially RBN sustains the load of the biggest #morsecode contest of the year! #hamradio

Those two beauties just happened to lie together on my desk. The small one (T37-61) is for my 30m QRSS transmitter. The big one (100mm OD) is N30 material and will be be a CMC for my lowband vertical at SO5CW. #CQWW in two weeks, need to start preparing things! #hamradio

#CQWW SSB 2025 at EI7M.
