Many folks that have purchased W1SFR keys eventually get a hankering to use them as a Cootie key. There are a couple of simple ways to do that. The easiest way it to get a 3.5mm stereo to mono adapter. Of course you’ll have to consult your radio manual and do what is necessary for it to accept a key in straight key mode.
The other way is to simply short the two contact posts under the base of the key. That can be as simple as a couple of alligator clips to a hard bridge soldered between the two posts. Either way you will most likely want to increase the contact spacing a bit to give you a bit more room to get your swing going cuz it’s a different feel than using it in paddle mode.
Here’s my most recent key, the “Torsion Bar Cootie/Paddle”. It comes wired as a regular single lever paddle, but is easily converted. Because the action is low to the deck, and the key has some decent rubber feet (not those stick on jobs, but real rubber feet with screws tapped into the base) it’s pretty amazing how well it sticks when in use. The contact mechanism is also a big contributor to it’s smooth action.
Sending with a cootie key is so much more personal than a standard paddle. Because you control the spacing, duration, and timing of every dit, dah and in between, your messaging takes on a whole different “feel”. Now…I’m not talking about sending out a bunch of slop, but like listening to a good bug op, a good cootie op is a joy to listen to.
Want to hear what some great sideswiper ops sound like? Give a listen to the guys on the sideswiper net. There are several nets around the world at different times, so it’s best to go to the http://www.sideswipernet.org website and check out the schedules. I try to make the Thursday night net on 7044 at 8PM DST. Also on the site is an amazing compendium of information about swipers and tons of pictures of keys made by scores of cootie lovers.
See you on the net!
