I reviewed the KX2 FAQ before replying and actually one can connect
an external computer to the KX2 and audio can be connected via
headphone and ext mic connectors and PTT via the computer connection,
so I would guess that freq stability might be the reason.
One cannot connect to external SDR programs as IQ baseband access is
not provided like the KX3 (BTW that is not provided in the K3, ether
but WSJT10 and probably JT65HF work off ordinary speaker audio into a
soundcard).
I can run either WSJT10 using my K3 LINE OUT or MAP65 using a LP-Pan
(SDR) on the first IF. LP-Pan provides IQ baseband audio for
computer based SDR programs.
Someone needs to run a test of freq.stability on the KX2 running
about 3w output in CW, holding key-down for 50-seconds followed by Rx
for 70-seconds to simulate JT65 heating and thus frequency
stress. IF 28-MHz holds under 20-Hz drift over at least ten minutes
than it is compatible for JT65; if not then that may be the issue.
Let me say my KX3's features suit my use(s) of the radio better. I
like having 6m & 2M internal to the radio. Recently had opportunity
to use the KX3-2M as base radio for my weekly 2m SSB Net and its
receiving ability with 214-foot of coax cable from my four yagi eme
array worked surprisingly well (normally I use tower mounted preamps).

Could Elecraft explain why the KX2 design doesn't allow operating say
JT65 out of the box?
What prohibits manufacturing the rig to do the narrow digital modes?
Would be helpful to know
Thanks
