Homebrew Nail File Cootie Key.
Since being licenced in 1983 I had exclusively used a straight key and had no desire to use electronic keyers (machines of the Devil ;-)).
Nearing my 80s I now have developed the infamous "glass wrist", so I took up the mechanical bug key J36. This allowed me to continue CW although I noticed it also narrowed down the number of operators that would respond to my calls, I guess the "lilt" of the bug was not to suite all ears.
During a contact with Nigel G0IIK I took a look at his QRZ page and saw his home made Cootie key and I think this was the magic moment.
Thus this is my first effort, the "Nail File" Cootie. I practiced for about a month before I dared have my first QSO on air. [G4ZXN].
Homebrew Veroboard Cootie Key.
Homebrew Meccano MK3 Cootie Key.
When I had my first QSO with Durk PA3BYW he kindly invited me to join the SSN the following Sunday evening, and also told me of the great web site. I was now truly hooked and researched many members home made keys.
One commercial key that stood out was the Russian KDM and this is my attempt to reproduce that key. Based on near proportions from a photograph, some Meccano bits, two strips of double sided PCB for the armature. "soft" contacts were made from two short pieces of an old alarm clock mainspring. I call this key "Meccano MK3". [G4ZXN].
Homebrew Neon Cootie Key.
Homebrew Maniflex Repro Cootie Key.
My version of the well known Maniflex Cootie key. Slightly wider at 2 Inches rather than the 40 mm of the original, all other dimensions are fairly close. In use I have found moving the adjustable pivot post closer to the contacts enables smaller gaps with less chatter giving a faster action.
I call this key Maniflex Repro. [G4ZXN].
