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
It’s late at night here, but I wanted to write a short post, because this is very notable. I have unfortunately found out that the esteemed Todd Gale, VE7BPO took down his amazing site, the QRP/SWL Homebuilder. Todd’s site has consistently been one of the best places on the web to get solid, entertaining, well-documented,… Read More Goodbye to QRP Homebuilder
I’m pretty happy with the way that the CRX1 turned out, but understandably I haven’t sold a ton of them because 1) they are a SMT kit and 2) the tuning range is a bit limited. However, it’s a stable and sensitive CW receiver and it’s pretty fun to build as well. There are still PCBs… Read More CRX1 Group Builds?
I’ve been working on getting the little bugs out of the Si5351 SSB rig and making improvements to the circuit. Since SSB QRP operating can be a bit more challenging than CW QRP ops, Dave AA7EE suggested that I think about a speech processor IC to use in place of the op-amp microphone amplifier. He… Read More For Noontime Net
Now that I think I’ve fairly well determined that the Si5351 is suitable for use in a ham radio transceiver, it seems like time to put thought into action and actually try to build one. Ever since discovering that the Si5351 can output multiple independent clocks from one IC, I thought it would be neat… Read More A Prototype for a Si5351-Based SSB Rig
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!
