Right now I have all of my keys going into a box that combines the lines so that I only have one thing to plug into the radio. I'll be re-doing this box so that I can put the new Bug Descratcher in there as well as an old Picokeyer kit that I used before I had cw memories built into my radio. The PicoKeyer will be used with the solid state relay in the descratcher to key my HW-16 with a paddle.
Below is a rough schematic showing how the internals will be hooked up. In order to have space for the Picokeyer controls (memory button and speed dial) I'll have to reduce my inputs from 5 to 4. I'm also adding a switch so that I can use the output of the descratcher to key my HW-16 or my K2.
I sat down around 6 PM and started to it. The Bug Descratcher is almost a non-kit, there's about 10 parts and putting that together only took about 20 minutes. Adding the Picokeyer was more difficult than I had anticipated. I built it back before I had a lot of soldering experience and used some bad solder (read: acid core) so when I tried to modify it a bit, I did end up ripping up a trace. I figured out where it went though and just wired up a jumper.
The next difficulty was getting everything back in the box. I tried to put the Picokeyer in the box so that the push button that controls the memory would work but the way that the box is designed, the Picokeyer won't sit flat so the button binds up on the hole. Either I have to enlarge the hole or add an outboard button, which I may do anyway.

See you again soon, 73!
