Then set the output of NaP3 to Line 1 Virtual and set the input of your digital program (e.g. MixW2) to Line 1 Virtual. That ought to do it. If not, I am out of suggestions, but it should work. Note that the sound card for your digital program shouldn't be the same sound card used to decode the I-Q.

Re: [Elecraft] KX3 I/Q output for pandapter
You should also have some sort of galvanic ground isolation on the line from the KX3 IQ to the sound card. Also, If I recall correctly, the 0202 has a way to lift the grounds on the input lines. Experiment with those as well if you are having image issues. 73 Greg On 8/2/12, Tony Estep estept...@gmail.com wrote: On Wed, Aug 1, 2012 at 9:40 PM, Buck k4ia k...@aol.com wrote: ...the signals are not there - just images == Buck, I have NaP3 running with my KX3, and it works fine.

Re: [Elecraft] KX3 I/Q output for pandapter
Buck, I've had results similar to what Tony describes. I'm using a external Griffin iMic as the soundcard. It works well, and I have been able to use a Virtual Audio Cable (VAC) to route the NaP3 audio to a 3rd party digital mode application (I use Fldigi). You still need an external cable to route the audio from the soundcard output to the mic input of the KX3, you can't use a VAC for that. It works just about like my Flex radio does configured that way, except with full break-in CW! My Flex-1500 is looking for a new home now.

Re: [Elecraft] KX3 I/Q output for pandapter
Buck, I have my KX3 running using the NaP3 software with the same sound card you have. The operating system is Windows 7. The one thing I found out quickly was that I needed the beta driver from Creative Labs. The rest of it was a little more than a little fiddling with the set up. But, it works rather nicely. I can point and click and the the radio tune to that signal. It's great!! I also have PowerSDR-IQ running with the radio, but it only operates as a panadapter; PowerSDR-IQ doesn't control the radio like NaP3. There are just two issues I've run into. The first, I have not been able to get VAC to work with NaP3. Secondly, I can hear the refresh click in the outputted audio. This doesn't happen in any of the other SDR software I've tried. Some suggestions: 1. Start with the sample rate set to 48 KHz. 2. Install Omnirig - available for free on the web 3. Make your input and out put card set to the EMU-0202 and use the audio jack of the soundcard to connect to a powered stereo speaker. 4. Make sure you are really plugged into the EMU-0202 as you think you need. Best of luck and enjoy. 73, Barry K3NDM - Original Message - From: Buck k4ia k...@aol.com To: elecraft@mailman.qth.net Sent: Wednesday, August 1, 2012 10:40:09 PM Subject: [Elecraft] KX3 I/Q output for pandapter I am fooling around with an EM0202 external soundcard and NaP3 which works just fine with an LpPan pandapter providing the I/Q from my K3 but I am not having much luck with the KX3, I have turned on the RX I/Q in the menu and run the I/Q output from the KX3 to the soundcard. I had to crank the gain way up but the signals are not there - just images, a blip in the center frequency and mirrored spurs on either side. . Before I go crazy trying to get this to work, is it fully implemented at this time and should it work? If it is, I will go about trouble shooting my cables and connectors. -- Buck k4ia K3 # 101 KX3 #715 __ Elecraft mailing list Home: http://mailman.qth.net/mailman/listinfo/elecraft Help: http://mailman.qth.net/mmfaq.htm Post: mailto:Elecraft@mailman.qth.net This list hosted by: http://www.qsl.net Please help support this email list: http://www.qsl.net/donate.html __ Elecraft mailing list Home: http://mailman.qth.net/mailman/listinfo/elecraft Help: http://mailman.qth.net/mmfaq.htm Post: mailto:Elecraft@mailman.qth.net This list hosted by: http://www.qsl.net Please help support this email list: http://www.qsl.net/donate.html
