Eric,
First, you cannot use PSK D for PSK31 with a computer unless you are
using the K3 Utility. All PSK31 software that I know of, other than the
K3 Utility, works by creating the PSK signal in a sound card and sending
that to the radio. In PSK D the radio does not accept audio input. It
can accept ASCII text input through the computer interface, but apart
from the K3 Utility, as far as I know there is no other software that
uses this method. To send PSK31 from a computer using standard PSK
software, put the radio into DATA A mode, which accepts audio input from
a sound card.
Second, to use CW input for either FSK D or PSK D, you have to use a
paddle connected to the K3's internal CW keyer. The radio does not
accept CW from the key jack for this purpose, and therefore you cannot
an external keyer or CW software.
In FSK D, the way software such as MMTTY keys the radio is by commanding
a serial port to key the TxD line with the Baudot code at the chosen
speed. This line must be connected to pin 1 of the ACC connector through
a keying circuit.
In AFSK A and DATA A, an audio signal is fed from the computer's sound
card to the K3's LINE IN jack.
Third, while N1MM Logger does not support PSK D, it does support the
other three data modes. It calls FSK D "RTTY", AFSK A "AFSK", and DATA A
"PSK". Open the N1MM Logger's Configurer and select the Mode Control
tab. On the right side of the window is a pane for "Mode sent to radio".
Beside RTTY, select RTTY if you want to use FSK D, or AFSK if you want
to use AFSK A. When the Logger is placed in RTTY mode (either because
the contest is an RTTY-only contest or because you type RTTY into the
Entry window), the radio will be put into FSK D or AFSK A depending on
how you have set up this panel. Beside PSK, select PSK, which will set
the data mode to DATA A whenever the program is in PSK mode. You can
also set the mode by clicking on the mode at the top right of the
Bandmap. Each time you click on the mode, the program will step one step
through its list of modes.
Fourth, if the function keys in the Entry window are displaying CW
messages, the program is in the wrong mode. Assuming you are in a
contest module that permits digital modes, type RTTY or PSK into the
call sign box and press Enter. The program should now select the digital
message set. The messages should start with {TX} and end with {RX}.
These messages will be sent to MMTTY or MMVARI or Fldigi, which in turn
will send them to the radio in the appropriate format (audio for AFSK A
and DATA A, on-off keying in FSK D).

Rich VE3KI
