You can use the raspberrypi as a nice little panadapter for the KX3,

Tnx Mike for the feedback. Wanted to verify I had not missed something.
Nice idea on switching multiple inputs. Had not thought of that.

Since updating my K3 f/w to 5.01, I find that the time to switch between
VFO A and B has increased noticeably - it used to be near
instantaneous. This is not good when used in a contest and needing to
switch rapidly between frequencies. Anyone else noticed this?

Be aware that for warranty work in Italy you will have to pay shipping both
forth and back.

Tnx Dick. I may have to hook up a third monitor temporarily to see if I
would really use the keyboard plugged into the P3 with its SVGA functions.
If I like it then I will have to decide how to best set it up on one of the
two existing monitors.

Hi,
I have a pi with a GPS shield attached that I use to run an NTPD server.
Not having internet access I needed an accurate time source for digital modes.
It has worked out quite well.
Check out:

Received a PX3 for Christmas. Have been very happy with the unit.
However, I noticed what appears to be an inconsistency. What I have
observed is that at certain spans (e.g., 2, 5, and 10), the PX3 refresh
rate appears to slow down depending on the KX3 digital mode selected (e.g.,
AFSK A, Data
I built one of those, and it was an interesting
learning experience. But its performance doesn't
come close to the PX3, which I later acquired.
Panadapters tend to be an addictive operating
tool. Once I started using the K3-P3 combo I found
that operating any rig without one was like flying
But how does that compare to shipping back and
forth across the Atlantic, Poul? Being 300 miles
from Elecraft that's a comparison I've not had to
make -- but Rickard did mention that factor in his
message, so I thought perhaps he was not aware of
the Italy option (and I don't really know if
Hi Brian,
The slower refresh rate at narrower spans is normal. The reason is that at
these narrower spans (below 24 KHz) we effectively down sample the I/Q
stream. Down sampling requires the PX3 to acquire many more samples for
each screen which directly affects the refresh rate.
The
In case anyone is interested in using QtRadio (i.e. from the ghpsdr3-alex repo
on github) with their KX3, I've bodged together the ghpsdr3-kx3-server project
on github.
I hope someone finds it of use ...

Darren,
Interesting. Thanks for the heads up.
I see Beaglebones Black mentioned at one of the
links. Is that what you're running it on? I'm
surprised if it has the capacity (I just gave my
BBB a grandson because I thought he could better
use it!).
If so will it run on a Raspberry Pi?

Neat Darren. That's quite a noise floor you have there on 80. :-)

Its is RF hell here, although the dBm values and S-meter scales shown in QtRadio
are uncalibrated.
The NR in QtRadio isn't quite as nice as the KX3's NR with the stereo effect,
but the autonotch and tracking notch filters (visible in the spectrum) as green
bars seem to be better than the notch in
Bob,
Thanks for your answer.
Hopefully, it lays to rest the idea that I didn't know what I was talking about
when I described it as the sound of a reed relay following the key.
(Hmm, mechanical motion initiated by electromotive forcesort of describes
a relay doesn't it?)
That said, I'm
Make sure the big toroid power transformer is tightened down properly. The
tendency is to avoid tightening it too much, fearing some damage will occur.
The transformer needs a bit more than that. I'm sure you will get a better feel
for it shortly.
