Thanks for the input I'm using the suggested iMic which does have a line
input and a mic input. I'm beginning to believe that it really is that the
radio is not working correctly. I'm going to reach out elecraft directly to
see what I can do without sending the radio to them for the fact that I'm
iSDR does require a USB soundcard with a stereo mic input, like the Griffin.
The easiest way to check if you are utilizing the stereo mic function in iSDR
is to check your iPad screen while running it and see if you are getting 22 or
44 kHz. If it shows 22, you are only getting mono mic.

I will report back after trying some of the I/Q based softwares out there,
however I did try iSDR which is supposed to work with USB sound card, it
didn't work. I'll try the windows based program tomorrow and report back.

I tried with iSDR which is made for iOS, sound card is working, RX I/Q is not
from my radio.

Help:
Kevin,
You are unlikely to hear anything from the headphones from that jack.
Feed it into a soundcard and you should see something using a panadapter
application like HDSDR or NaP3.
The RX I/Q output is low level and broadband. It is not suitable for
digital mode software like FlDigi. For
The jack is 3/32 inch or 2.5 mm.
Have you tried connecting the I/Q output to a computer and some SDR software
that actually uses I/Q input?
I don’t think you’ll hear much using phones. Scope should show the signal I
would think.
Be sure to push plug all the way into the hack. It is very
Thanks ALL for the help.
I'm still getting zero audio out of RX I/Q and want to make sure that I have
done my due diligence trying to figure out the issue. I'll have some
adapters on their way later today for the 1/16th inch jack to put headphones
on it that way I don't have to trust that my
Do you still want to use this for fldigi? It is the wrong output for that.

I did check that the RX I/Q was enabled and still hear nothing, on my
computer, when plugged in to the RX I/Q port. I'm ordering a set of adapters
so that I can put my headphones on the radio directly to see what I hear
then. Thanks all for trying to help...
I still wonder if I should hear
See Menu section of manual. RX I/Q needs to be turned on.
RX I/Q OFF Set to ON to use the KX3’s RX I/Q jack with the Elecraft PX3
Panadapter, or
with SDR (software-defined radio) applications (pg. 26).

See the note I just sent you. You may have not turned on I output.
That is my suspicion.

Thanks for the prompt repl
Kevin,
The RX I/Q is at a low level, and is only usable for a panadapter like
the KX3. It works for those applications because the signals are 90
degrees out of phase (which is what quadrature means).
For Fldigi, and other soundcard data mode applications, use the Phones
output to feed the
The levels from the RX I/Q are very low, so you might not hear anything.
Pages 26 and 27 in the manual talk about using that for computer-based SDR
applications.
Also, check the RX I/Q menu setting. If that is OFF, you won’t get any output
from that jack.
Finally, fldigi does not use I/Q
Thanks for the prompt reply, I guess the question that I would like to answer
is, if I were to plug in to both sides of the RX I/Q port should I hear
anything at all? If I shouldn't then great, if I should then I'm going to
need to figure out what's going on with my radio such that I can't heard
Kevin,
The I/Q output is an analog two channel audio signal, but one of the
signals is 90 degrees delayed from the other, hence in quadrature. If
you plug the output of the I/Q port, one channel at a time into your
computer mic input, you will hear a wideband audio signal. There will
