Summits on the Air -- Bear Mountain, WA

I recently became interested in Summits on the Air (SOTA) and went up on November 7th for the first ever SOTA activation (ham radio jargon for making radio contacts from a specific place) of Bear Mountain near Lake Chelan. I made amateur radio contacts around the country on 10 watts of power. This was only my third SOTA activation, though I've been active in ham radio for a few years now. I got into Parks on the Air (POTA) in early 2020, just before the pandemic hit the US. So far it's been fun adding SOTA to the mix and I am looking forward to more adventures with ham radio.

I wrote a more detailed blog post of my experience on pnwsota.org.

Arduino and Morse Code

I got an Arduino to tinker with over winter break, and one of the ideas I had was to write a decoder for Morse Code (video below).




I ended up with a hacked-together bit of code that can decode Morse in real-time, and display in on an LCD.

Parts list:


I followed these instructions for wiring up the LCD (though I did change which pins I used).

My code is available via Bitbucket.

I even (temporarily) got my hands on a vintage telegraph key, and got it wired up!

My cousin trying it out!
