[Elecraft] KX3-2m CW problem

[Jack F6AJW]

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.
