Is anyone configured their K2 to utilize the P3 Panadapter?

Hi All,
The P3 Panadapter if provided an I.F. should be able to work with a rig
other than the K3.
Has anyone modified a K2 for this?
Do we know if the KX3 has an output option for setup with the P3
Panadapter?

Thanks

Interested in your impression of the KX3 compared to K2 and K3

Hi All,
I am not a contester.
I enjoy digging faint signals out of the noise.

I'm wondering what your experience with the KX3 is compared to the K3
and K2 in that regard.
If there is a significant improvement in capturing weak signals over the
K2, I might put the KX3 on my Christmas wish list. :)
I'm really curious about it as it appears to be an SDR device.

Please feel free to email me directly with your observations if you
wish.

Thanks!

I have both but did not make A/B comparisons.

K2's filters are not too sharp but they pick up weak signals very well. But may be overwhelmed by strong signals nearby. K2 has excellent AGC.

KX3 has much steeper filters and even APF. Also continuously adjusted. So probably KX3 would do much better with a mix of weak and strong signals. KX'3 AGC is not as good.

Im no contester or DXer, but generally the KX3 seems to pull signals out of
the noise with narrowing filter width better than the several k2 units Ive
used. The noise also seems less harsh. I havent found the APF to my liking,
it seems to ring too much compared to just narrowing down the passband. NB
works much better on KX3, and Im not sure yet on NR compared to k2dsp.

KX3 is definitely easier for me to use than my K2, but I still enjoy both.

Duane,

The KX3 is definitely an SDR - the K3 is too - the firmware defines the
function of the radio.
Somehow the "SDR" term has become construed in some ham's minds that a
computer is required if it is an SDR, but look at the "Software Defined
Radio" literally - the firmware loaded into the radio determines how it
functions, and that is what SDR really means - anything extra is an
extension.

Comparing the KX3 with the K2 and K3 is a different question. They will
all perform quite well, and are all in the top area if the Sherwood
listings. The big advantage of the K3 and KX3 over the K2 is that the
RX bandwidth is continuously adjustable where the K2 is only adjustable
when you do the filter alignment - you have 4 filter bandwidths per mode
to work with - on the K3 and KX3 that is adjustable in infinite steps
with a knob control.

The KX3 vs. the K3 question is one of operating convenience and
preferences.If you are looking for portable over the convenience of
connections, then the KX3 is the better choice. The K3 has more jacks
to connect to external devices such as a soundcard for digital operation
while the KX3 can do that too if you use a cable to the mic and
headphone jacks, but that replaces the normal mic and headphone connections.

So all 3 are quite capable transceivers - decide on your usage
preferences and make your decision on that basis..

73,

One more item to add to Don's excellent comment. As someone who
prefers to build equipment rather than get it preassembled, the
K2 is available as a you-build-it kit. The K3 and KX3 are only
available as you-assemble-it kits.

I spent a year and a half dithering between the K2 and the K3
thinking, "Better radio vs. building it." I ended up with the K3
and am quite happy, but I still hear the K2's siren song. (And I
will probably get a KX3 for portability before the K2, so go figure.)

Cheers - Bill, AE6JV
