here is the situation: I hold xmit to tune the ameritron al 1200 to
1400 watts.Then when I key the mike all i am getting is 300 watts
out. i hold tune again and it is showing hi power.
help pse!

Since the original manual was written, there's been a subtle change to
the operation of the TUNE button on the K3:
Originally the TUNE button gave a power level as set by the PWR control,
in the more recent firmware the way it operates is different.
There is a menu setting of "TUN PWR"
K3/100, firmware 1.78 MCU/1.58 DSP, mine gives plenty of RF envelope
with a peak of 100W on my 100 MHz scope.
No issue with peaks, overshoot or anything at all, the audio reports
from several stations are also very complimentary. There's nothing wrong
with either the "loudness" of the signal or
Well my problem is persisting. I TUNE to full power key the mike and
only peak 60 % of the 1.5 kw. Then I will TUNE again and quickly key
the mike and it will peak at the full 1.5 kw only to revert to a
lower level on subsequent keying of the mike.
this has not happened on any other of the
Todd,
I had the exact same problem when I tried to use my K3 with my
amplifier.
I did not have a ground on the K3. This was a test in a high RF
environment.
When I grounded the K3 the problem disappeared.
When I grounded the power supply the problem disappeared.
I now have both grounded.
How are you measuring power? As stated before, unless you are using an
active peak power reading wattmeter, you will not be correctly reading your
peak SSB output. My Diamond SX-1000 reads about 25% of the peak power on
SSB. My Array Solutions Powermaster reads the same peak power on SSB and

Are you using a true peak reading wattmeter? An average meter will only
read about what your seeing. Jim K4JAF

There have been numerous posts on this topic.
I wish somebody using current firmware would get out an oscilloscope and see
if the K3 putting out peak power or not on SSB. A study with various gain
and compression levels would help.
You can bet when my K3 arrives, I'll test this.

I'll sell you my K2/100. It will run your AL-1200 to
full limit. I cannot use it with a high gain amp, such
as a HF-2500 Magnum (20w for 1.5kw), because of the
unstable K2/100 output.

Todd...
More information please. From readying your posts I am not sure what rig you
have and what mode you are in and what exactly you are doing. Could you be a
little more specific as to the parameters you are using.
I have no issue with power with my K3 and my amp. Perfect control on
