QCX-mini CW radio kit from QRP Labs

Hans G0UPL made yet another addition to the family of QCX transmitter kits. QCX+ is good as I wrote previously but QCX-mini is even better!

I was not lucky enough to get my hands on the kit from the very first batch but patience is gold. On a bright side revision 2 PCB I received does not require a hack with an additional capacitor in parallel with C38.

I’ve received the kit, built it and I love this tiny rig!

Same way as with my previous post I will try to avoid repeating the excellent build and operating manuals but I do have a few nits to pick.

Bonus: WSPR beacon mode test.

ARRL Winter field day 2021 - Mt. Umunhum

ARRL Winter field day 2021 - Mt. Umunhum

ARRL winter field day! Time to get out to the Nature and work portable! Which is how I do it all the time duh.

My initial plan for the field day was to drive to the Tahoe area and try activating Mt. Tallac. Weather made corrections - Northern California had been pummeled by rain and snow that week and I decided to wait for snow to set before making an attempt.

Safe and easy plan B I fell back to is activating Mount Umunhum aka W6/CC-052.

Due to the fact that the mountain had been closed to visitors until recently it is not featured in popular culture as frequently as other prominent Bay Area peaks.

And yet another SOTA report from the Bay Area - this time it is about Montara mountain with its highest point - Scarper peak also known as W6/NC-288.

It may be of a surprise to you but european explorers were oblivious of San Francisco bay existence for quite a while. For example Sir Francis Drake most likely stopped to careen his ships in what is now called Drakes bay during his 1579 circumnavigation voyage and search for a North-west passage. English later were trying to use his landing to dispute Spanish and American claims on California.

Only in 1769 Juan Gaspar de Portola and his companions discovered the Bay. The monument commemorating this event is located on the Sweeney ridge trail hugging Montara mountain from the north.

Hey-hey, buckle up for yet another SOTA activation report! This time our guest is Mount Diablo aka W6/CC-045.

Need to confess - as a kid I spent an unhealthy amount of time playing Diablo and Diablo II games. Dark atmosphere, fast paced real time isometric combat and RPG elements made for an ideal mix. While I could spend more time studying instead of wasting time playing games there is hardly any other piece of media that made me wish to become a software engineer more. Well, maybe Might & Magic VI. And also probably Doom. But Diablo is definitely one of the trinity.

Why do I mention that? Because Diablo game had been named after Mount Diablo. Don’t trust me, check David Brevik talking about the game.
