Ask yourself how many additional options are you going to add to that

The K3 with the internal 2m module works excellent and it doesn't have to
hang off the back of the transceiver. As for the 70cm the only choice for it
is the transverter as far 6m if is already in the K3 to begin with.
I use a smaller amp to drive my large 2m amp and it works out quite well

It should not be necessary, but I would first connect the K3 direct to
the computer com port (eliminate the P3 from the serial port chain).
Then look at the K3 Utility help file (or the K3 manual) for Forcing a
Firmware Download. Follow those instructions to get the K3 running again.
The case was sold but the sale did not work out so the unit is back on the
market.

Another suggestion is the Gamma Research HPS-1a, which has a very small
footprint and will power a 100 watt radio. So if you get an amp you will be
covered. I have the HPS-1a and it powers my K3 just fine and is easy to
transport for portable operation.
I have been running multiple programs (K3 Utility, WSJT, N1MM,
Digipan) that send PTT or other info to/from the K3 over the serial port

Only one program is running at any time so no problem.

You can connect just one physical RS-232 computer port to your K3; RS-232 is

I've noticed that the CW sidetone always comes in above the VFO frequency or
the VFO +- the CW pitch by the amount of the pitch.
For instance, if the VFO is set to 7.040.000 and the pitch is set to 600 on
the KX3 and in the Options tab of NaP3, the sidetone shows in the waterfall
at 7.040.600. If

It would be easier to just hook up the KX3 to the PC with the Phones jack
to Line In on the PC. Then the KX3 has already demodulated it for you. If
you use DATA mode then it will be a raw USB or LSB chunk ready for use in
your favourite digimode program.
If you still want to listen to the KX3,
Kjeld, you might consider the K144RFLK option too. That locks the K144XV's
internal oscillator to the K3's master reference oscillator for enhanced
frequency stability. Without it, the stability of your 2-meter rx and tx
signals is that of a normal crystal oscillator.

It's option 3 :-)
When you select CW mode, the KX3 will not set the frequency of its local
oscillator to be the same as what it displays on the screen, but will offset it
by an amount corresponding to your preferred sidetone pitch (eg. 600Hz). This
way, when a CW signal at the frequency shown

Yes, that is what I am using : audio cable and external speakers via the PC. I
