 I decided to take a breather from the SWR bridge and the swr sweeper to build this: it's my build of a "Duinovox" Basically an automated T/R switch for use with digital modes. The original design is by Kevin Loughin, KB9RLW. His blog is here: KB9RLW Blog.

Kevin's Youtube page is here: Duinovox KB9RLW.

Which is where I first saw it, not too long ago actually. The big difference between Kevin's unit, and the one I have built is that I designed a quick and dirty PCB in Kicad, then had it manufactured at OSH Park. (I hate point-to-point wiring) The board is not the prettiest I've ever designed, but it will do....

Here's my unit:

I also added an on-board regulated power supply, as I was going to keep my USB sound card external to the case I eventually put this into.

I will give a report a little later, plus, I will have a Rumble video up as well.
