[Elecraft] K3 PSK issue - How to?

Did you put the K3 in Data A mode?

You should be running mic gain so that ALC barely registers, or below.
Zero is Good.  Set the power however you want.

I included a previous summary of settings I've uesd that might help
out with this.

K3 s/n 24

== stapled-on ==

Data MD:  Data A

TX line in setting:  20% of full scale.  The output is a laptop's
speaker jack and the setting reflects the playback volume set on the
laptop.

RX line out setting:  55% of full scale.  The input is the mic jack of
the laptop.

RX Filter:  shift it to 1 KHz Fc, and 200 to 400 Hz bandwidth.  Stir
as needed....

K3 Line In Gain:  set at 1 to 2.  This range seems fine, but it won't
help to go any higher than 4 or so.  IMD gets worse.

K3 Line Out Gain:  leave this at the default 30 setting.  It works
fine.

K3 Mic Source:  Select Line In.  Don't forget to put it back when you
return to voice modes.

PTT-Key:  I ran it DTR-Off, but you could also use RTS for keying.

Set up at the home QTH is as follows-
K3/10
MFJ-941 tuner
Long wire antenna - 130' long at 35' above ground.
Two stereo cables - 3.5mm to 3.5mm, both male
USB:  Elecraft KUSB.
Digipan 2.0 running on XP Pro, SP2.

I had a power setting of between 3 and 5 Watts.  With PSK31, that's
enough.
