Hi Terry, I thought you might like to see how I constructed and packaged the first keyer kit I bought from you about three weeks ago. I used 3 sub miniature push switches, a 3 x AA battery box and a standard ABS case part number KC93B, all of which are available from Maplins over here in the UK. I drilled the holes with a 1 mm dia drill using 0.1 inch pitch perf board as a template and guide then widened them out to 1.5 mm diameter later. I calculated that the 52 holes needed to depict my call sign created a total hole area of approx 100 square mm, more than sufficient required to carry the sound coming from the small 2 mm dia hole in the sounder, out of the case so I could hear it. Feel free to copy this text and any of my pictures to the group members site, if it will help to promote sales of the keyer. 73 de Russ G3OTH

Terry et al,
Attached are my "build notes". Click here for Rick's pictures and additonal notes. I built it before the manual was done, but that is OK; perhaps my alternate ideas will be useful. I thought my litle "daughter board" for the 5V regulator circuit worked out well. My only additional comment on the manual is that on the top of page 2, reference is made to "Section 4" and "Section 5" (done, wa0itp). You may want to number the section headings and the Table of Contents.
I tried all of the commands and functions except the mute function (nothing handy to hook it to). I found the method for entering memories a little awkward at first, but with practice it is not bad. The end result, tho is perfect code in the memories. (My K2 does a great job of mimicking my crappy character spacing when I record a memory). The command entry is otherwise very easy to use. I like the easy adjustment of code speed.
The mute funcion is a great idea and will make this a great keyer for home brew rigs and "minimalistic" separates.
Terry, Craig, thanks for all of the effort. I know it is time comsuming to put even a simple project like this together. And thanks for the opportunity to beta test.

For those who's hearing isnt what it has been, you may wish to substitute a larger speaker. The Radio Shack 273-073 works very well. It fits on top of the pc board, see AAØZZ's picture on the photo page
I used the keyer in the Iowa QSO Party and it performed very well. I operated from 9AM to 6PM almost continously and the keyer never faltered. You know the routine, call CQ make the contact, call CQ etc. With it's user frendly design it was smooth, efficient, and was very easy to operate. The best thing that can be said for a keyer is that it performs perfectly and seems invisible in use. That was certainly the case with the AAØZZ EZKeyer.
