On May 3, I'll cease bench experiments blog posting and go outside in our garden. To keep in touch with other radio and QRP work bench enthusiasts over the spring summer, I'll employ Twitter. Here's a quick glimpse at the front end filter — amplifier in test mode. I swept for S21 and performed DC measures last weekend.

A reader saw a photo of my old W7ZOI crystal characterization oscillator (with the suggested switch from Dr. Gordon-Smith, G3UUR) in the site archive. I had removed its crystal holders to yet another such oscillator and just soldered in a crystal as a PROP for the photo. This photo "suggested" it was OK to solder in the various crystals under test. My bad — I apologize. Oscil...

Notes on a few experiments for my Jupiter receiver. I departed from my 5 normal month radio hiatus to blog because it’s super-hot outdoors and our basement feels oh so cool. Sometimes, too:. If I wait too long to post stuff, I lose passion or worse yet — forget details and/or lose data. I love the works of Anton Chekhov. This post arose because I wanted to design my own Jupite...
