CAT on K3

[Robert Dwiggins II]

I was looking at the specs on the K3, and they look impressive.  However, I
was wondering which CAT functionality will be included.  Will it be possible
to control the pot settings (AF/RF/mic gain/NB gain, notch, passband tuning,
variable bandwidth IF filtering, etc etc) via the RS232 port?  In other
words, will most if not all of the rig's functionality be controllable using
a software interface such as Simon's Ham Radio Deluxe?

The word is that anything that can be done from the front panel can be
done from the computer interface.

Ultimately, yes. Every control on the K3 is read by the same MCU that
interfaces to the serial port.  There are no signals that pass through
any switches or pots.

Yes. But our remote control interface also allows the computer to send
low-level signal processing and control commands directly to both the
main and sub receiver DSPs, bypassing the main microcontroller. There
are on the order of 100 specialized DSP commands, including those for
setting up arbitrary filter bandwidths and center frequencies.

I don't know if any other transceiver gives you this level of control.
It'll be a lot of fun for software developers! For example, you could
create your own DSP filter profiles for specialized applications.

One other tidbit: Once we've caught up with other firmware commitments,
we hope to add stored macro capability, with supplemental commands for
timing intervals in seconds. This would allow you to, in effect, write
little applications that run on the K3 unattended, doing
multi-band/-mode frequency hopping, complex beacons, hunting/scanning
for "CQs" from specific prefixes in CW/data modes, etc. You'd be able
to run/stop a number of individual macro sequences via the front panel.

A guy can dream, right? We'll be seeking input on all this when the
time comes. Not yet  :)
