If you wouldn’t mind, I would like to draw your attention to my latest post on the Etherkit App Notes blog. In it, I detail how to create a 10 milliwatt WSPR beacon using nothing more than the Etherkit Si5351A Breakout Board, an Internet-connected PC, and a low-pass filter. A simple project, but one that… Read More 200,000 Miles Per Watt
I’m pleased to announce an upgrade to the Etherkit Si5351A Breakout Board with TCXO reference oscillator. In boards manufactured previous to today (and the ones kitted in the initial crowdfunded initiative), the TCXO used was a Fox FOX924B-25.000. It worked well and did the job it was supposed to, but has one flaw in certain situations. The… Read More Si5351A Breakout Board TCXO Upgrade
More Musings about Etherkit’s Future As I mentioned in my previous post, we are still undergoing a stage of tremendous upheaval in our household. I won’t really know how our new life will shake out quite yet, but I am certain that my time will be more restricted. I think I’ll have a good grasp… Read More Wideband Transmission #7
I know. I was just starting to get some momentum posting to the blog on a semi-regular basis, and then — the drop off. I am sorry about that. The Si5351A Breakout Board campaign consumed almost all of my work time. Given the limited amount of actual work time that I have, something had to give.… Read More Long Time, No See

Just a few days ago, I finally received some of the TCXO parts that I’ve been planning on using with the Si5351A Breakout Board. I had no problem using one on the remaining prototype circuit board that I have, and at first glance it appeared quite stable and also very close to the nominal frequency… Read More Si5351A with TCXO Update
Happy New Year 2015! 2014 was a bit of a mixed bag here. It’s been a transition year for Etherkit, as I reorganize and reorient the business for a renewed push to get the CC1 and other new products to market. I believe that good things are beginning to happen there. On a personal level,… Read More Wideband Transmission #6
In looking through the analytics here on the blog, I noticed a search term that has been regularly coming up near the top: Si5351 crosstalk. Realizing that I haven’t yet presented data on this, it seemed like a good time to knock this one out, since it isn’t that difficult of a measurement to make.… Read More Si5351A Investigations Part 8
Latest CC1 Progress As you can see from the above photo, I have finished a significant portion of the digital side of the newest CC1 prototype and now I’m on to the receiver section. This weekend I finished my first pass of the audio chain and characterized the gain and frequency response of the chain.… Read More Wideband Transmission #5
You may have already seen it, but please allow me to direct your attention to my latest post on the Etherkit blog. For the tl;dr version: sorry to have been quiet on the business front so long, also sorry to have failed to do a good job keeping up on business communications, the OpenBeacon and… Read More Etherkit Rev B
