Curt, I think you and Jerry are correct that in general most do not care if hams home brew the radios of other designs and show them off.? They even encourage it.? Ashhar Farhans uBitx transceiver

Here is my last batch of 10.7 crystals to test. In order to make it easier for me to keep track of the little darlings I used the color code on the tops with an unused color to mark the "head". Number

JLCPCB lets you put multiple circuits on one 100x100 panel for the super cheap price. They won't cut them apart and you can't show scribe lines(IIRC). I cut them apart with tin snips, wish I had a

I think I have bad news for you William.? In the order process, when you submit the Gerbers, an engineer on the team will inspect the board.? If it does have multiple boards, separated by regions

Daniel Interesting. I imagine the copyright is to disallow someone from commercially selling that manual or large portions of it, likely with a kit. QRP rigs are published to encourage experimenters

Great ideas. How about making a 100mm X 100mm PCB layout of these circuits, generating the Gerber files and turning on the serration flag so you can submit them to a board house offering a special 5x

Daniel, The TI chip was test of a video amplifier.? It was not a drop in replacement. The point, I think, is that we have to find someone who has experimented with them to point out pros and cons.?

Chuck, About the headers - yeah, I like the idea of using an IC socket and headers than doing dead bug style.? Good idea here. And I want to build a SST-20.? Is the Video Op Amp TI TL592P a drop-in
