Keying on the other transverter bands is fine, it's just the KX3-2m module.
Thanks to all,

Very interesting -- I hooked the KX3 up to a scope, set it at 30wpm on 2m with
VOX OFF, and sent a continual stream of dits. This is what I saw:

The dits are in fact quite uneven (some nearly twice as long as others), and if
you listen to a continuous stream of dits it is indeed obvious to the ear. Also
as you say, this problem does not occur on the other bands.
It seems there may be some sort of timing issue in the firmware; I guess this will get
added somewhere on the "to-do" list.

Hi Matt,
Thanks for your response! Good idea, but it is not a RF feedback. It happens
also with VOX=off (RF output power=0). With a audio record (e.g. Audacitiy or
scope) of the sidetone you can see, that dot length is very unregular (set
speed to 40 wpm). If you do the same on a HF band, each dot has the same lenght
- perfect.
On 2m CW is useful with low speeds only. On higher CW speeds the sidetone is
very irritating for keying.
tnx es 73, paul hb9axl
Just tried 2m CW using a begali paddle plugged in to the KX3 internal keyer,
the CW sounds fine to me (up to 30wpm at least, unfortunately that's about as
fast as I can go). I'm wondering if you might be having some sort of RF
feedback issue? What sort of antenna setup do you have?

Hi all,
CW on 2m is a problem. Especially with speeds higher than 25 wpm the timing of
the sidetone becomes very unregular (eg. continues keying of dots only). With
an external keyer the problem seems to be even worse. QRQ CW sounds very dirty.
CW on HF bands is perfect.
Any others who can confirm this problem?
