JT and all,
Pins 2 and 3 are not swapped on the K2 either. The problem is that the
K2 used the nomenclature differently than the K3. The K2 used 'TXD' to
denote the line *it* was sending on and 'RXD' to denote the line it was
receiving on. The K3 apparently uses the opposite nomenclature and
labels *its* data *output* line 'RXD (that is correct for a DCE device).
Pin 2 is the data from the DTE (K2 or K3) to the DCE (PC) and is
normally termed RXD. Pin 3 is data from the DCE (PC) to the terminal
device (DTE) and is normally labeled TXD.
This has been a source of confusion when working with DCE devices for as
long as I can recall.
So *if* only RXD and TXD with Signal Ground are needed for the
application, yes, the K2 cable (computer end, not KAT100 or XV end) will
work just fine, but why not pick up a standard serial cable and take
advantage of the PTT/Keying circuits built into the K2 - that will work
with no external keying devices.

Yes, but the K3 is wired differently.
On the K3, pin 2 is RXD and pin 3 is TXD
On the K2, pin 2 is TXD and pin 3 is RXD
Also, some K2 serial cables use additional pins for things like XV and
KAT100 control.
