First place in Colorado and the Zero Call Area, with a modest score. Apparently set a record but this is a relatively new contest.

I’m trying out JTTY this morning on 20m. This mode has potential but there is a LOT of confusion about operating procedures.

It’s not FT8, it’s not RTTY, it is…confusing 😀

🚨 WORLD’S TALLEST MEDIUM-WAVE MASTS JUST FELL. The twin 355-meter Liblice B towers in Czechia, taller than the Eiffel Tower and once the most powerful MW transmitters in Central Europe at 1.5 MW, were brought down simultaneously after nearly 50 years as the country’s tallest structures. Built in 1976, their service elevators ran on combustion engines rather than electricity, and technicians needed roughly 45 minutes to reach the top. As ground-based radio giants give way to satellites and fiber, these unique engineering landmarks are gone in about ten seconds.

Tomorrow Joyce/K0JJW and I will activate Lassen Volcanic National Park (US-0049) for Parks On The Air. This activation celebrates completing our goal of visiting all 63 US National Parks. Lassen is our last one. Look for us around 1900 to 2100 UTC on 20m SSB. We may do some FT8, FT4 as well so watch pota.app for spots.

I just became aware that this book, Software-Defined Radio for Engineers, is available from Analog Devices as a free download. A great resource if you want to dig deeper into SDR technology. analog.com/en/resources/tech…
