KX2 waterfall

Hello,

Does the PX3 panadapter work for the KX2?

Does anyone with a KX2 have a different panadapter-esque solution?

I have a 7” android tablet that I was hoping to use as a waterfall
display/mobile computer for portable ops. But I could just as easily
substitute a small laptop or raspberry pi if necessary.

Open to any suggestions!

Thanks and 73

Re: KX2 waterfall

Adam,

The PX3 uses the RX I/Q output from the KX3.
The KX2 has no RX I/Q output, so it cannot drive the PX3.

Win4K3 does work with the KX2 and it has the capability to provide a
panadapter display. Just how that is done for the KX2 I am not certain,
but you may want to check out the Win4K3 webpage.

Hi,
Here is a video on how to set this up with the KX2. https://youtu.be/fxJq-aQivGk
It will be pretty much the same for the KX2 except that you need the appropriate cable to turn on the switch when you go into transmit. Also note that there is a newer MFJ switch called the MFJ1708SDR which no longer requires soldering a jumper.
You can use this with an SDRPlay and Win4K3Suite or any software and corresponding SDR.

Re: KX2 waterfall

Tom, Don,

Thanks! Win4K3Suite seems like a great option. From the video, if I
understood correctly, the MFJ switch splits the sending/receiving paths
such that the SDR play is used as the receiver, rather than the KX2. Is
there any impact to receiver performance? Can the KX2 noise rejection,
filtering, etc still be used? Or does the software do the heavy lifting
there instead?

Will look into trying this out....

Thanks and 73,

Re: KX2 waterfall

Adam,

As I understand it, the KX2 is the receiver for your normal operating.
The SDR play is the receiver for the panadapter only.

As far as transmit and receive are concerned, the KX2 should operate as
normal (although you can use the rig control portion of Win4K3 if you
want to control the radio via mouse-clicks.

The SDR Plus provides the panadapter display and through the programming
of Win4K3, it will track the tuning of the KX2.

If I did not get that right, I am certain Tom will 'chime in'.

Hi,
Don is perfectly correct. Since there is a splitter there is a 3dB or so loss in the signal.
It's worth trying out. The latest releases also come with the EiBi shortwave databases and will show the station info on the spectrum. It's amazing how many shortwave stations are still out there and when you think propagation is bad, you will still finds lots to listen to. Brings back memories as a young kid with my two transistor SW converters..
This set up if you can stand the wiring, will work with the KPA100, KPA500 and the KAT500.

There was some chatter a couple months back about a board designed by UC6UAA that replaces the KXIO2 board.

Re: KX2 waterfall

Pretty cool. Might have to look into this...

Thanks!

Re: KX2 waterfall

They're available on ebay, apparently, and the listing links to videos of
the required modification.
