Author Topic: Key that works like the dash paddle of a Vibroplex Original  (Read 19620 times)

« on: September 03, 2013, 08:35:53 PM »

In my novice days, I purchased a 1950's Vibroplex original from a former Railroad operator.  I soon thereafter dropped the thing and broke the main spring.  Being a poor teenager I began to send with the dash contact of the bug and got quite good at it.  I have never used a keyer and don't want to.

Many years later I got the key restored by Vibroplex, and intend to keep it as a bug.  I would like to purchase a straight key that lets me use my wrist-rotating motion to send like the dash contact of my bug. 

Any recommendations?

Buy a J-38, and a set of right-angle steel brackets at the hardware store.

Mount the brackets on a base, and mount the J-38 on the brackets.  That will give you a straight key, with sideways activation.

There is precedent for this.  One of the early designs for an iambic paddle used two J-38's, back-to-back.

Or, use any iambic (or single-lever) paddle, and ignore one paddle.   [A sideswiper has a different action -- there's no positive center stop.]

Use your bug,  just use the dah side for staight key keying and then as a regular  bug when you want to go full semi auto keying, if you own the Vibrobroplex already then no need to buy an additional key unless you  just want to.  I also like the feel of using my bug as a straight key, I find the comfort level  much higher then using a standard straight key and you can really send pretty fast with it that way. Side keying with the dah side I can send 25 wpm easy and never really get tired, I use  my two fingers and tap away, it works like a champ.  Just make sure if your a hard pounder that the bug does not slide on you if your desk is smooth,   Good luck and have fun ,keep CW alive no matter how you like to send,  73 Jim N0XE

Hi N0XE!

The only problem I have with staying with the bug, is that I find I have to set the stops so that the dit side cannot operate otherwise I sometimes overshoot and cause a errant dit.  I was hoping to avoid having to fiddle with the key between modes.  It might be worth it. 



Thanks for the input

I used to use my Bug's "dah" side when working with a new ham who couldn't quite copy the Bug at around 15WPM - the slowest I could set it with the pendulum loaded down with clothespins  Grin .

This was back in the very early '60s - I referred to it as "working Single Sidekey".

Try a Vibroplex Vibrokeyer.  It is a single lever paddle that is mostly made from Vibroplex
Original parts (no mainspring) on a smaller base.  You can wire it up like a straight key using only the dash side and lockout the dit side with the adjustment screws if you like.  This should give you the right feel.

Good Suggestion, one I had not considered.

Slide a business card or painter's tape between the dot contacts to prevent the overshoot contact.
