The theme of this blog post is not lots of tedious work, but refinement leading to good results. First off, let’s talk about the funny I2C address on the parts which I received from Mouser. Since Digi-Key has no order minimums and very inexpensive shipping available (in the form of USPS First Class mail), I… Read More Si5351A Investigations Part 6
I’m happy to report that the CRX1 40 meter receiver kit is now in full production and is available for purchase in the Etherkit Store for $40 (which includes all controls and connectors, you just add some wires and an enclosure). Allow me to quote from the product page: The CRX1 is a simple VXO-tuned… Read More The CRX1 Is Here!
This is the first in a series of blog posts covering a wide variety of topics. In the past, I have used Twitter for my microblogging needs. For a variety of reasons, I’m on a Twitter hiatus right now, so I’ll be using this series to convey some of the disconnected (and possibly connected) random… Read More Wideband Transmission #1
As a mild winter turns into an unusually nice spring here in Beaverton (last week we had multiple days with clear skies and highs in the upper 70s °F), a young ham’s thoughts turn to portable activations, Field Day, SOTA, and the like. I’ve been looking forward to this summer for the opportunity to take… Read More Stuff ‘n Things
Last night, I had the very first 2x CC1 QSO with Dave AA7EE on 40 meters. Rather than try to blather about it, I’ll let the video do the talking. Needless to say, we were both quite stoked!
Last night after the rest of the family was in bed, I was hacking on the CC1 firmware to add the BFO calibration routine so that I could get an accurate readout of my receive frequency. After successfully completing that task at the late hour of 0130, I decided to cruise 40 meters to see… Read More The Thrill of QRP DX
A brief post to show you the CC1 prototype, now inside of its aluminum enclosure. This is the actual enclosure that will be used for production, but I will have the end caps custom cut and silkscreened, so you won’t have to do it yourself. Pardon my questionable metalworking skills, and please note the the… Read More CC1 #1
Two days ago, I received my pack of 10 CC1 prototype PCBs from Seeed Studio. The excitement was too much, so I immediately started building the first CC1 prototype as soon as my wife got home from work. Not surprisingly, I didn’t go to bed until I completed the build, sometime around 3 AM. I… Read More First RF
Yes, a belated Happy New Year greetings! It’s hard to believe that 2013 is already well under way. I figured it was about time to give you a quick update on what’s going on in the shack right now. First up is the discrete component grabber receiver for 14.141 MHz that I prototyped to be… Read More HNY
Hello there. Yes, there is still life at this blog, although whether it is intelligent is still indeterminate. I feel awfully guilty about the lack of content for the blog in the last year, but I’ve been in a horrible time crunch since getting Etherkit off the ground. When it comes to making the choice between… Read More Inflection Point
