This is a simple conversion of the KX1 iambic paddle (KXPD1) to a single lever paddle.
i never was able to convert over to iambic keying since i learned to send CW with a regular Vibroplex bug. i have always been able to send faster and with fewer errors on a single lever paddle. When i have to use any iambic paddle i must keep my fingers spaced really far apart. The conversion uses an exoskeleton plastic case over the KXPD1 iambic levers. The exoskeleton case prevents the operation of both levers at the same time. i found an old 9 Volt NiCad battery (Eveready type CH22, really 7.2V, that has the 2 snap clips on the top), i took all the NiCad cells out and the case fits right over the iambic paddles. This case is made of a one piece plastic shell. You must remove the KXPD1 rubber boots and shorten the plastic battery case a little. Fine spacing adjustments can be made by taping thin pieces of postage stamp size cardboard (3x5 card stock) inside the plastic case. Now the last task is to hold the case in place and to get the case to pivot around the levers. i placed a long uninsulated terminal lug under the top left paddle PCB screw and formed it up to the top of the key. This made a little peg for the case to pivot on. Then i epoxied an Exacto knife to the top of the case. The hole in the Exacto blade fits over the peg. The case can now easily be attached for single lever operation or taken off for iambic operation. (You could drill and tap a small hole in the aluminum block and put in a small screw to make the pivot but it isn't as adjustable as the lug). The plastic case doesn't fall off when you are walking around Pedestrian Mobile either... i have a photo of the final paddle conversion in the W0RW photo section of HFPack2.

Now after using it and it adds 15 wpm to my sending speed. Necessity is the Mother of Invention ! Paul [EMAIL PROTECTED] Paul Signorelli [EMAIL PROTECTED] P.O.
