I have a problem with my Kenpro KP-100 Squeeze keyer ...
I will not Reverse Key on one side ...
Shane -

What do you MEAN, Reverse Key ????? No compremdee!
Do you desire the change the assignment of the paddles for DOT and DASH usage??
Do desire to change from Iambic A to Iambic B ??

What’s all this iambic keyer mode A and B stuff, anyhow ?

There are NO user friendly external controls to perform these changes -- without revising the the keyer's circuit.

... been looking for a schematic for this and no luck ...has a instruction manual which does not help me understand ... any help on this one would be great .. Thanks, Shane.
You may have to reverse engineer the schematic,
unless you call the Japanese telephone (or FAX) number and ask for a copy of the schematic!

It is said by this Spanish collector, that the KenPro KP-100 is the Japanese version based on the famous Curtis integrated keyer (EK-38), allowing multiple adjustments but instead has no external paddle.

Hi mate ... Sorry if you didn't understand.

What this keyer is doing:

IF you ground the DOT paddle and then ground the DASH paddle, so now both paddles are grounded --
it should change to dashes.

Now that works fine lol .... BUT

IF I ground the DASH key and then the DOT key both now grounded, it keeps sending dashes ...
so this makes squeeze keying abit hard! hihi.

The instruction manual that Kenpro sent out is no help!

Ok mate hope you can understand it better now.

tks 73s for nw ...

What is the Slide switch on the REAR Panel of the KP-100 set to???
SEMI or AUTO?
Semi-Automtic makes the keyer operate like a Vibroplex bug -- not an Iambic keyer!


I think Kenpro has been taken over by Yaesu, and I have asked them if they have any info, but their answer was No.
Yaesu purchased the antenna rotators that Kenpro was making several years ago (> 15 years).
