Re: [Elecraft] NAP3 setup with KX3
Found the problem thanks to your suggestions. After a bit of digging discovered that the X-Fi Go Pro has no stereo mixer. Switched to the slightly more expensive and much bulkier X-Fi Surround and now works well. Thanks all.

Re: [Elecraft] NAP3 crashes with KX3 USB
Sounds like clashing drivers or a driver that is incompatible with way you are operating. I suggest that you contact the maker of your USB/serial adapter and get an updated driver. 73, Barry K3NDM - Original Message - From: Pete Meier pme...@mac.com To: Elecraft@mailman.qth.net Sent: Friday, June 14, 2013 7:48:22 PM Subject: [Elecraft] NAP3 crashes with KX3 USB NAP3 crashes when KX3 USB/Serial cable is plugged in.

Re: [Elecraft] NaP3 and the KX3
I've been struggling with HDSDR and a Griffin audio device to bring the audio from the the Elecraft RX I/Q cable in via USB. I get a big center spike in the display with two side traces. Someone else posted they had a similar display anomaly with NaP3. Several posts seem to indicate it is a little better than HDSDR and I'm happy to switch. Any advice on setup/configuration would be appreciated. 73, Paul K7NHB -- View this message in context: http://elecraft.365791.n2.nabble.com/NaP3-and-the-KX3-tp7564924p7572086.html Sent from the Elecraft mailing list archive at Nabble.com. __ 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
Re: [Elecraft] NaP3 and the KX3
I've posted before about this issue. I've given up trying to get NaP3 to provide any useful information. It's not vital to my operations so I'll do without. I've not tried HDSDR so I can't comment on that. I too am using the Griffin device as recommended by Eric to me at the Orlando Hamfest in February. I guess the Griffin is doing what it's supposed to be doing, but I see no signals of any kind on any of the various displays provided by NaP3. I'm having too much fun DXing QRP to worry alot about the bells and whistles.

Re: [Elecraft] NaP3 and the KX3
Paul, Usually the big center spike is due to a so-called ground loop between the computer_plus_soundcard and the KX3_plus_power source. The two ways to cure this are: 1) bond everything together with low-resistance, low-inductance straps, or 2) use audio isolation transformers. There have been lots of posts here about candidate isolation transformers. I have no idea what the two side traces might be. How far apart are they from the center spike? Are they symmetrical on either side of it? What is their amplitude? Do they get masked by band noise when you have a tuned-up antenna attached to the radio? Apart from the three spikes, is the panadapter otherwise working on your computer? 73, Lyle KK7P I've been struggling with HDSDR and a Griffin audio device to bring the audio from the the Elecraft RX I/Q cable in via USB.

Re: [Elecraft] NaP3 and the KX3
Gil, I don't understand what problems you are having. I've been running NaP3 almost as long as I've owned my KX3. The only problem I've run into is ASIO with VAC. Seems that VAC will not accept 24 bits. Other than that, I've been pleased. I've even shown the operation to a few other hams. Having said that, there are a few idiosyncrasies. First, there is a latency issue just like the Flexradio users have raised. The way around that is to use the NaP3 only as a panadapter during timing sensitive periods; any other periods, just operate like a Flex. Second, I occasionally need to do a reset of the IF frequency offsets, not a big issue. And lastly, unless you set the 8KHz offset, you will get a spike at 0. You will need to do an 8 KHz. by band, but it is totally transparent when operating without NaP3, meaning set it and forget it. Just one caution: make sure you tell NaP3 you have an 8 KHz IF. Do try again. It's really a great operation when it's running. I rarely run without it these days. 73, Barry K3NDM - Original Message - From: Richard Gillingham w...@hotmail.com To: k7nhb desig...@quickdata.com, elecraft@mailman.qth.net Sent: Monday, April 1, 2013 7:52:04 PM Subject: Re: [Elecraft] NaP3 and the KX3 I've posted before about this issue.

Re: [Elecraft] NaP3 and the KX3
Lyle I suspect that the spike at zero has to do with the fact that the radio is direct sampling and the IF is zero. Elecraft has built in an at least a partial fix, the 8 KHz. receiver offest. That has helped at my place. The second that added a little bit is a galvanic isolator I picked up at Radio Shack for about $10. It didn't totally remove the spike, but it did knock it down a bit. 73, Barry K3NDM - Original Message - From: Lyle Johnson kk7p4...@gmail.com To: k7nhb desig...@quickdata.com Cc: elecraft@mailman.qth.net Sent: Monday, April 1, 2013 8:50:35 PM Subject: Re: [Elecraft] NaP3 and the KX3 Paul, Usually the big center spike is due to a so-called ground loop between the computer_plus_soundcard and the KX3_plus_power source.
