Wideband Transmission #5
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
Etherkit Rev B
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
Wideband Transmission #4
It’s been a while since I’ve posted one of these. I understand that things have been fairly quiet over here in the last few months, so I wanted to let you all know that I’m not dead yet. I’ve actually been working on Etherkit a fair amount in the background, and that has been eating… Read More Wideband Transmission #4
CRX1 Open Beta
If you don’t follow me on Twitter, you may not have heard that I have been working on a little “warm-up” kit in preparation for the CC1 release. Called the CRX1, this kit is a little VXO-tuned superhet receiver based on my 2010 FDIM Challenge entry, the Clackamas. The CC1 is also a descendant of… Read More CRX1 Open Beta
Wideband Transmission #2
CC1 Beta Kit For Sale I ended up having one leftover kit from the CC1 beta test and I thought that an experience builder might like to build it. There are a few minor mods to perform to the PCB, so it’s best suited for someone who feels comfortable with that. The (hopefully) final PCB… Read More Wideband Transmission #2
Wideband Transmission #1
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
Stuff ‘n Things
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
First CC1-to-CC1 QSO
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!
The Thrill of QRP DX
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
