Good evening /bonsoir Paul, Olli, Wayne and All,
Thank you for your comments. Here, output power is the same using
internal batteries or external 13.8V in FM or SSB; here, I can perform
precise power measurements up to 24 GHz. Thanks in anticipation, Wayne,
for power improvement to come.... May be that a future software release
will manage to also improve rejection of birdies too. For the moment, I
have just tried with an external antenna 3 elements Yagi antenna located
a few meters from KX3 and it was the same situation regarding internal
birdies. Interesting to know what is the behaviour of 4m module compared
to the 2m one?
73's.

Bonjour Jacques,
Merci pour votre reponse!
TX output 2W:
Do you apply enought supply voltage? Min 2.5W are specified with
13.8VDC supply.
Birdies:
Yes, it has quite a few. But for my use this is much less tragic than
the CW trouble. Hope you will find a solution for your usage.
Merci es 73, paul

Sorry Paul, no answer to your problem with CW (not yet tried).
On my side, I am a bit disappointed with my KX3-2m because of low TX
output (2W instead of 3 announced) and lot of birdies on dummy load in
RX mode. When using an external antenna, noise level increases and some
birdies disappear but not all especially on 144.400 MHz. Do not try to
connect an antenna (flexible quarter wave in my case) directly on SMA
socket, you will receive a lot of birdies so, no way to use my KX3-2m
like I used to do at the end of 70's with my IC-202 transceiver and
telescopic antenna.
Any way to cure my problems?

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?
73, paul
