[Elecraft] KX3-2m CW problem

[paul hippenmeyer]

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?

73's.
