USB Sound Card
Locked

I’ve looked at the L-pan site and they recommend the ASUS USB sound cards. Reviews on Amazon and NewEgg are pretty negative. What are the group’s recommendations for a USB sound card interface with the K2 and KkX3:

Tom,
For many years, I used a Creative Labs E-MU 0204. The last time drivers were written for that interface was late 2014 and it is no longer in production. When I upgraded to OS X 10.11, I could not use the interface because of some changes in OS X. I purchased a Focusrite 2i2 and cannot be happier (unless I had purchased the Focusrite 6i6 for more I/O). I regularly decode JT65 and JT9 in the mid -20s. I have had at least one JT9 decode at -27 using the Focusrite. The 2i2 is available from most online big-box places for right around $150. All you will need to purchase the appropriate cables. With both the K3 (I know you said K2) and KX3, I use a 3.5 mm TRS to 1/4” T and R mono from radio out and a 3.5 mm to 1/4” mono to radio input. The Focusrite USB interfaces are red anodized aluminum and you can adjust both input from the radio and output to the radio with dials on the front. It also has a separate headphone stereo monitor that can be turned on and off with volume adjustment. The adjustments right on the front of the Focusrite make operation very easy. 73, Joel - W4JBB > On Mar 6, 2016, at 16:51, Tom Field <[hidden email]> wrote: > > I’ve looked at the L-pan site and they recommend the ASUS USB sound cards.

Tom,
I use the Steinberg UR22. It seems to work well for me. 73, Barry K3NDM ------ Original Message ------ From: "Tom Field" <[hidden email]> To: [hidden email] Sent: 3/6/2016 5:51:51 PM Subject: [Elecraft] USB Sound Card >I’ve looked at the L-pan site and they recommend the ASUS USB sound >cards.

Tom,
Tom, If you want to use the soundcard for panadapter applications, then go with the recommendations on the LP-Pan site, but there are several users that have been reporting that the ASUS U7 reverts to 48k and there does not seem to be a solution. The ASUS U5 does not seem to share that problem. In addition to the bandwidth of the card, the noise floor and the lack of a zero frequency spur are important considerations. Look at the LP-Pan Yahoo Group for a lot of comments. If your soundcard will be used for digital modes only, then you do not need a 'top of the line' soundcard, most any will do. But the LP-Pan website can still be an assist in selecting one - look at the noise level on the various cards to find the better ones for soundcard digital mode use. The internal soundcard in your computer may prove to be adequate, but turn off the sounds generated by your OS if you use the internal card so you do not transmit those sounds. 73, Don W3FPR On 3/6/2016 5:51 PM, Tom Field wrote: > I’ve looked at the L-pan site and they recommend the ASUS USB sound cards.

That's strange. Never heard a single issue with the Asus u7 stuck at 48 and i know of many many people using them. The only reason that happens is that people often set the card as the default sound card which should not be done.The u7 in my experience, is the quietest and least likely to have Spurs.Cards to stay away from now a days with win10 are the emu cards. Upgrades to win10 may work but not fresh installs. Drivers are at least 4 years old and still beta.Tomva2fsq.com

I used a SignaLink for quite a few years and then I changed to a
Tascam US-122 mkII. When I used the SignaLink on PSK, I had to ride the RF gain to keep the digitized audio volume within acceptable input levels. With the Tascam, I no longer need to do that. The downside of the Tascam is it requires special drivers which aren't available for ARM linux. You can get by with a minimal sound card, but there is value in a better one. 73 Bill AE6JV On 3/6/16 at 3:53 PM, [hidden email] (Don Wilhelm) wrote: >If your soundcard will be used for digital modes only, then you >do not need a 'top of the line' soundcard, most any will do. ----------------------------------------------------------------------- Bill Frantz | Security is like Government | Periwinkle (408)356-8506 | services.

The reviews on Amazon and NewEgg need to be taken with a grain of salt.
The vast majority of those reviews are from people who aren't technically inclined and you get a lot of "it sounds great" reviews. If you're using this for the LP-Pan take the advice of N8LP. He knows what works with his hardware. You might think about joining the Yahoo group as well. If this is for a Windows 10 computer you may be stuck in driver "no mans land" until ASUS releases drivers. Welcome to the wonderful world Windows OS "upgrades".

Any competent sound card will work for that. Spectrum display? I'd go with N8LP's assessment on that. 73, Jim K9YC ______________________________________________________________ Elecraft mailing list Home: http://mailman.qth.net/mailman/listinfo/elecraft Help: http://mailman.qth.net/mmfaq.htm Post: mailto:[hidden email] This list hosted by: http://www.qsl.net Please help support this email list: http://www.qsl.net/donate.html Message delivered to [hidden email] |

Tom,
If the problem is only happening when the Asus U7 is the default soundcard, then how do you deal with the tendency of the Windows operating system to set any newly installed soundcard as the default? Seems like a "catch 22" to me. Yes, the specs on the Asus U7 are very good, but for panadapter use, it needs the 192 kHz bandwidth. 73, Don W3FPR On 3/6/2016 7:05 PM, tomb18 wrote: > That's strange.

I use a U7 with the KX3 and HDSDR. There is an issue with the
initialization of the 24 bit drivers. I have set up for 24 bits, 192 kHz and line in using the Asus software, and 24 bits and 192 kHz in Windows control panel. When I turn the computer on and use HDSDR for the first time I have to do the following: Start up HDSDR and select Start. In HDSDR switch to 16 bit drivers. In HDSDR switch back to 24 bit drivers. In HDSDR select bandwidth and switch the output bandwidth to 192 kHz and back to 12 kHz for the small waterfall. The input remains 192 kHz. In HDSDR close the bandwidth box. In HDSDR hit Stop and then Start After all that it works until the computer is shut down or the computer sleeps. If the computer sleeps, in HDSDR hit Stop and then Start if the spectrum is backwards (moves the wrong way when you tune) or is mirrored around the center. Other than the annoyance above, it works well. I just live with the "dance" at startup. Hope this helps 73, Mark W7MLG On Sun, Mar 6, 2016 at 6:04 PM, Don Wilhelm <[hidden email]> wrote: > Tom, > > If the problem is only happening when the Asus U7 is the default > soundcard, then how do you deal with the tendency of the Windows operating > system to set any newly installed soundcard as the default?

I use an Asus XONAR U7 with NAP3 and CW Skimmer on a Lenovo Windows 10.x machine , attached to the K3 IF via LP-PAN2. Almost all USB sound cards are quirky to set-up with your particular computer and your particular audio applications. As for the "stuck" 48k sample rate: make sure the little switch under the XONAR U7 is in the USB Audio 2.0 position, then follow the guidance for loading the correct driver - do not let Windows load the default driver.
I hope this helps. 73, Terry K4RX Tom, If the problem is only happening when the Asus U7 is the default soundcard, then how do you deal with the tendency of the Windows operating system to set any newly installed soundcard as the default?

Yes.
Also once any potential driver issue is rectified and the sound card is installed remember EXACTLY which USB port you plugged it into and use the same port always. Even though the driver is installed if you disconnect and reconnect to a different port Windows will see it as a new device and start the driver dance again. Unless plug and pray has gotten a whole lot better (I doubt it).
