I'm trying to get my K3 running on PSK31. Everything seems fine so
far. I'm using line in/line out into mic and headphone on my laptop.
Copy is very good. Transmit drive is touchy and I'm wondering if anyone
has any tips on setting the correct amount of audio drive. My power is
set to 20 watt

Doug,
Do not use the power output as an indication for mic drive on data modes
(PSK31 for example).
The proper indicator is the "ALC" bargraph - adjust the audio input for
4 bars with an occasional flicker of the 5th bar.
At that level, it is not an indication of ALC action nor compression.

Wes,
The capability operates within limits - it cannot be infinite.
However, the K3 (K2 as well) uses a control loop for power output
control. It senses the output power and adjusts the RF drive to
compensate for differences in the power requested and the actual.
In SSB (and data modes) it oper

Lyle thinks it is still true with the latest code - I just checked!

Don,
Can this approach be used with the K2 in digital modes and if so what are
the suggested settings for the 'bars' when the ALC is turned on?

Snip
The K2 has operated this way all its life, but the K3 has a more
sophisticated detection mechanism, so control can be more precis
Nigel,
Yes, a similar procedure can be used with the K2.
The K2 ALC indication does indicate actual ALC, so the best setting for
the K2 is to increase the audio until you see a flicker on the ALC meter
and then back off slightly until it disappears.
Because there is no MCU compensation for band
