KX3

Does anyone know how to hook up the proper cable,?, to run an SDR like HDSDR on the KX3 withthe PX3 also hooked up. We are also using the KXPA100 amp.
I know the end that fits in the IO R on the PX3 is a 2.5 mm can I use on the other end a USB A.Where might I find this cable? I only have USB connections on my Asus Laptop.

Re: KX3

When using the KXPA100 amp with the KX3 the control is via the amp. USB to
3.5 cable plugs into the amp and feeds through to the KX3. No computer to
KX3 cable is needed, just computer to KXPA100. Same cable you would use on
barefoot KX3.

The I/Q feeds through the PX3. You need to take the I/Q out of the PX3 and
send it to a high quality sound card, usually a USB sound card.

If you want wideband, choose a 192 kHz card from here:

I use a U7.

The rig control also feeds through the PX3 and the amp to USB on your
computer.

Hi,

Chose instead the U5. It is slightly less money and is just lacking a bunch
of fancy audio features that have no use in a panadapter. Also all the
cables come out on one side which makes for neater cabling.

I believe Asus has overcome its early failure problem(s). I have had mine
for at least two years and no failures have been posted her for a long time.

Tomy,

The KX3 to KPA100 cable assembly and the KX3 to PX3 cables are involved.
The PC connects to the KXPA100 using the KXUSB cable to control not
only the KXPA100, but the PX3 and the KX3 as well.

In other words, the PC cable connections are "daisy-chained" From the
PC to the KXPA100 first, and then to the PX3 and then on to the KX3.

Re: K2 with KXPA100

In reply to this post by ab2tc

Greetings all,

How could I use the KXPA100 amp with my K2? I don't think the K2 has a keying line, and so I wonder if the KXPA100 would automatically detect band and frequency through the built-in tuner without a keying line cable. Any info appreciated.

Re: K2 with KXPA100

Jay,

You will need to key the amplifier with a keying output from the K2.
Yes, the amp will detect band and frequency, but you still need a KEYOUT
from the K2.
The best solution is to use the N0SS Amplifier Keying board. Since Tom
is SK, no kits are available, but I understand you can obtain the boards
from FAR circuits - or the circuit is simple enough that you can build
it on perfboard using Tom's full size board layout. See
http://www.mmccs.com/mmarc/n0ss/k2_t-r_rly_drvr.pdf.

Thank you for your help at RARSfest - the Amazon package arrived today -
Thanks.

That buffer amp is for an IF output from the K2, and is NOT an amplifier
keying output.

Re: K2 with KXPA100

You are correct Don, Far Circuits does have the board for the N0SS amp
Keying circuit. I have installed it in both of my K2's and works great.
They also have the board for your fixed Audio out. They are hard to find on
his web page so I just called him and he took care of my order.

Don (and Ed and Heinz),

Thank you for the information. I have Tom's legacy website so will look up the board.

Don, I enjoyed my day with the Elecraft gang at the hamfest; thanks for the invite. I'll see you at Dayton, if you can make it.
