Let's go to the video..

Chuck, K7QO, has posted some videos on his QRP Tech NorCal40A project on YouTube and I have relocated those published as of this date here. They are similar to his 1-Watter series except a little quicker on the up-take. That is, there isn't a lot of hand-holding. You either get it or you don't. I have added them here (and will try to add new ones as they are published).

No embellishment; here they are:













In addition to those, there's a video Chuck recently released on crystal checking. He uses a Morse code enunciator but a Colpitts oscillator in conjunction with a frequency counter can be used.

Whatevs.


Knock yourself out!

Resurrection..or just waking up?

After what may seem like an interminable slumber and having just retired from a career of software development, I am now enjoying the fruits of my labors. (For the record, this is different than when Herb Caen famously observed that the owner of Finocchio's, where female impersonators were the staple act, lived "off the labors of his fruits".) In any event, I land upon these sandy shores with a healthy list of projects and opportunities to push out my wonderful experiences in electronics and QRP. What lays before me are hopefully idyllic days of building, soldering, testing and operating.

Note to visitors: I shall close the loop on the ARN/UM-25D cleanup (done many moons ago) and the wrap-up of the One-Watter series later. In the mean time, herewith is a post re the nascent project being started by Chuck Adams and the QRP-Tech folks (citations hereinafter) are doing to honor the 25th anniversary of Wayne Burdick's NorCal 40A QRP rig. These are preliminary shots for the benefit of my bud, WB6JDH, who will join me and others in scrounging and building these beasts. Our aim will be to do an "SnS" (Scrounger and Solder) of the 30 meter version of this as outlined by W0CH (main page here and 30-meter version here.)

Here are the pics of the QRP-Tech boards and my original TRW Swap Meet NorCal 40A find as a reference and for Dick to survey:
