[Elecraft] Settings for PSK31 and the K2

[Ron D'Eau Claire]

You've got it Stephen! 

As with the others, limiting the power by limiting the audio drive is
preferable. It holds the IMD to a minimum. In any case, you want to avoid an
ALC action with PSK31. 

As for isolation: the K3 has fully-isolated audio inputs and outputs ;-)

What isolation gets you is freedom from hum due to ground loops than include
the mains supply lines. I run a notebook PC and when I'm operating PSK with
my K2 I just run the notebook on battery! No problems that way even with
direct connections between the K2 and computer.

FSince I need to limit the output power anyway due to the size of the KPA100
heatsink, am I still better off keeping the output power control on the
front panel of the K2 at maximum and reducing audio drive so that I get
about 30W output, or should I reduce the output power on the front panel to
30W?  With my previous rigs I have always been driven by the necessity to
see no ALC action on the meter.  Is this the same with the K2?
