#hamchallenge week 6 - Whistle a DIGI- or CW-QSO!

While it says this is an easy challenge arguably whistling a digimode might be very hard. Hint: It doesn't say you need to use a radio anywhere. Maybe you toot a video of yourself whistling and receive a mention back? https://www.hamchallenge.org/challenges/7/toots #hamradio

@hamchallenge I have managed to make around 5 QSOs today at Vokspark Schönholz (POTA: DE-0173) on 80 m with only 5W. Surprisingly a connection to the north of germany yielded consistently good signal reports while I adjusted the power output of my transceiver lower and lower. I have completed my activation on 80 m by increasing power and made connections to Germany and Poland. I have used an ATU-100 tuner and an End-Fed around 6-7 m up in a tree. HC04S #hamradio

#hamchallenge week 4 - How low can you go in QRP?

This challenge is about hitting the lower bands with your QRP rig: How low can you go? Can you make it to 80 m or maybe 160 m? Hint: The mode is up to you 😉 https://www.hamchallenge.org/challenges/5/toots #hamradio

Today, I managed to make a QSO via a repeater in London (GB3LV) using #Echolink. The repeater is connected to a larger network, and I had a QSO with EA7KNK from Spain. Many repeaters seem to be connected via a wide variety of networks, so you can connect via Echolink and then end up via Allstar in Spain on another repeater or an operator's hotspot in Turkey...
In any case, the first Hamchallenge of the year has been completed HC01S #hamchallenge @hamchallenge

If anyone else is still working on the challenge, I am now QRV on DB0BLO, which can also be reached via Echolink (call for DK4MJ).

Today I tested my newly built St. Louis 20 m POTA antenna with my QRP Labs QMX and I was blown away by how well this antenna performed. I have slightly remixed the original 3D model: https://www.printables.com/model/1537183-st-louis-pota-20-antenna-w-14-20x7-heat-insert-10 - Find the link to the original model in the description.

The #hamchallenge is starting into its second year!

In 2025 we had 70 different participants who submitted 798 toots. The most successful participant was Ian, M0TRT (@ian) who completed 41 challenges!

Thanks to Phil, DL9PK (@phikes) for taking over the organization and operation of the 2026 edition. He rewrote the website, open sourced it (https://github.com/phikes/hamchallenge.org), and collected challenges for the coming year.

Here's to a successful second year, and thanks for all the fun we had in 2025!

@hamchallenge I came up with the idea for HC01 because suddenly I heard a call from KE2FYY on a repeater in the north of Germany stating a QTH somewhere in NY. I thought that was a pretty unconventional QSO!
