Something *really* new at Dayton from Elecraft

I'm beyond stunned. This is even possible?

You should have it on the air in your vehicle.  What freq ?

Hi

How good is the IMD performance of the new radio?

It would be ideal for driving a Tetrode in AB1 passive grid with low drive.
The poor IMD performance of many small radios has stopped me from doing this in the past.  The FT817 is an example.

What RF devices will the new radio and the PA use?

A well engineered portable radio is a welcome addition to the market place.

Will there be a kit to convert it to a manpack radio?


The mind boggles at all the possibilities!

John

Only 150 mA? What do you use for DSP and micro-controller? Or do you do all
the work in the DSP itself? Also, what is the maximum current consumption
when 1:4 transformer is used? Must be significantly more than for 1:1 ratio.
(I am curious about CW mode - I assume it'd be running as a C or D mode, but
I could be wrong. Will its PA run in AB mode always, or will PA mode vary
depending on modulation?)

At 44.0 cu in, the KX3 is just about mid way between the K1 and KX1.
Nice job.

The microcontroller is like, but not the same as, the one in the K3. The
DSP is a new, 5th generation device designed for extremely low power
consumption, yet with performance exceeding that of the one in the K3.

And, of course, we played a few tricks :-)

Holy Toledo! Or should I say Holy Dayton! Really, really wish I could be there this year.

And there I was thinking, as Field Day approaches, how there was nothing that would ever pry my IC-703 Plus out of my hands. Once again Elecraft proves "never say never."

Congratulations gents - nice work! You're really going to wow the crowd at the Hamvention with this little beauty.

Hi,

The K4 was born, I think !!!

SDR?  So does this have out of the box panadapter support?

Will this external amp also work with Cletus's CB? He's been wanting a leen-yer...

Seriously, I always thought there was some FCC mandate against producing an HF-capable kit for this power/freq range. Perhaps firmware prevents CB use?

[Torsten Clay]

Here's something you might consider (or maybe already have :) )

If the KX3 front panel is almost identical in controls to the K3, maybe it could be paired with a K3 to act as a remote front panel. Similar to the detachable panel functionality available with many current mobile rigs. The advantage being that just the "panel" KX3 could operate as a self-contained QRP radio.

Pity, I was hoping for a "K4" with a bigger front panel with better ergonomics, better memory management, a band switch, a nicer display, FET finals and enough weight that it didn't skid off the desk when I pushed a button.

You must push REALLY hard!!

Have you considered replacing the bottom panel with an inch thick piece of lead :-)

[KK7P]

The KX3 receiver includes I/Q outputs for use with a PC soundcard.  This
allows you run various a third-party application software on an attached
PC, such as a spectrum display.

Of course, no PC is required to use the KX3; it is a complete,
self-contained radio.  With appropriate options (battery pack w/charger,
ATU) it becomes a complete, self-contained 160m-6m radio station.
