Thanks to the efforts of Etienne Scott, K7ATN, we who live in the Pacific Northwest have a couple of nice SOTA summit-to-summit activity days each year. One that happens in early spring and if I remember correctly the other which occurs later in the summer. I participated in the spring S2S Party two years ago, but… Read More SOTA After Action Report – Sheridan Peak
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

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
I don’t have a ton of new updates for you from the NT7S bench, but I wanted to give you a heads up on an error on the Si5351A Breakout Board Rev B and let you know about some exciting stuff brewing on the Si5351 scene. When I created Rev B of the Si5351A Breakout… Read More Si5351A Update
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
