[Elecraft] K3 and Expert 1K-FA

[Philippe Trottet]

Hi Franco,
Fully agree Arie's comments, I'm not using an auto Amp. only a manual
one with a Russian tetrode, and only checked on the K3 that the time
delay corresponds to the amp specs and that's all. 
With my K3-100, most of the time I'm driving it with 12W and the output
with my amp is ±350W thats cover most of my applications.  At 13W it
engage the KPA100 for higher power needs.
Just set the K3 to the power level you want to use without going over
the specs of your equipment.

Franco,

Forget about the ALC.
Up till now I have never used the ALC between my TRX and PA. No need
to.
Just gently set the power of the trx yourself to drive the PA to the
right powerlevel and go.

Hello
I  use the Expert 1K-FA  with K3 full power and ALC , but i think i
have
two issue.
When i use K3 full power ( with Expert full power ) the rig output  is
not  stable but fluctuates around 15 watt and more or less of 5 watt ,
and of course the output of Expert varies consequently .
When i use Expert half power i have not issue , the input and output
power are stable.
Another issue is that when i put the Expert in STBY , the K3 output
power does not return instantly at 100 w , but slowly in 3 - 4
seconds.
When i not use the ALC i have not issue.
Thank you
Franco I6QFZ
