Hello from VK,
The news of the KX3 has stopped my meandering amongst various 80's and some

inactivity until 2008. I am sizing up what it will cost to get a KX3 on air,

Yes, you can use the green wire or any other wire of a similar size.
The reason 2 colors are used is to have visual recognition for the

I think that if Elecaft made a K4 that will do what the Kenwood radios will
do.(UHF,VHF,1.2,SAT and so on) This will take away from what the K3 is all
about.

That part has nothing to do with the filtering - the next step is to
convert both the I and Q signals to digital and do the manipulation
mathematically - that includes filtering, detection, and most other
signal processing functions. The result is then converted to an analog

I concur there. Wouldn't take the K3 market, but rather open a new one that

I think 160m to 2m is asking a little much from a fractal patch antenna.
But from 20m to 2m should be within the ballpark of a dedicated antenna

bands. But some of the grad students at the U of New Mexico were

Hi Johnny,
I'm not familiar with the IC7800, but in general an image-reject mixer
uses the same basic principle. It's the same as the phasing method of
SSB generation used 50 years ago, except that they didn't use the word
quadrature or I/Q in those days.

A shame, too, since I was the lucky(?) winner of the 600m transverter

I ended up doing some swapping with the rep and got a dual band 40 and

On my K3, I have switched between the FIR and the IIR filters when I have
the DSP filters set to either 100 hz or 50 hz, and can tell no improvement.
You are probably using Rx EQ and have your preferred
sidetone pitch peaked to something more than 0 dB. RxEQ
is not available at these two narrow bandwidths.
Note: It seems that many people believe that the Rx EQ is
an *additional* filter cascaded with the normal DSP
filter. It is not.
