Best Audio Interfaces 2020?

Hello All,

I just scanned the archives for recommendations on a good external USB audio interface for sound card digital. In 2017 Jim (K9YC) recommended two (ASUS and Newmark) that are no longer available.

What are the current favs that are out there now?

TIA,
Eric

Re: Best Audio Interfaces 2020?

If you want to connect line level input/output, and you want to be able to monitor the input and output through a headset,
I would recommend :

Most of the products I recommended can be found on ebay. As with any
purchases online, pay attention to customer ratings and the "look" of
the listing.

Re: Best Audio Interfaces 2020?

The matter is that you will send all the OS sounds to that interface (because you have only one)- and at this point you need to chase all the notifications what will be sending sound, and you cannot watch youtube anymore :-)

Re: Best Audio Interfaces 2020?

If you have a K3s with the built in codecs that's not the case at all. It's
its own independent audio device.

For original K3 radios and other earlier rigs without built-in USB audio, I
recommend the Microham Microkeyer-II. It ran my Yaesu Mark V based shack for
about 10 years, and I got the cables to let it handle my K3s for a while,
but eventually I just simplified everything and I took the MK-II out of line
and resorted to USB connectivity. Not a single problem since then. PC
sounds, video, music, etc, go to the motherboard sound interface, and the
rig sounds (digimodes in/out and DVK from the PC to the radio) via the
separate USB interface built into the K3s.

If you have a radio without the USB interface ping me off-list and maybe we
can make a deal on my no-longer-needed MicroKeyer-II?

OK QSL.

All of my computers have soundcards including the, soon to be replaced, shack
Lenovo laptop. I tried a TASCAM US-100, highly recommended by K9YC, without
seeing any improvement over the Lenovo on digital modes.

The repurposed Chromebook I use for my field digital operating has the
world's most useless built in sound system. Even if you have one of the
goofy cables that will fit the sound socket, it won't work for digital. I
tried. I looked it up, and it's a design defect in pretty much all
Chromebooks. If you want to really use sound on a Chromebook, you have to
use a sound dongle.

I reflashed the Chromebook, taking out the old ChromeOS and replaced it
with GalliumOS, a Linux distro for Chromebooks, and it works great with a
sound dongle, but the internal sound hardware is just so awful you can't
really use it for much of anything. So I don't I use that Techrise dongle I
got for $17 and it works perfectly. I pair it with my MDS Phaser 40m
digital mode QRP rig, and it makes a very compact little FT8 and JS8
station, with the appropriate Linux versions of the apps installed.

I could have cobbled up something from a Raspberry Pi, but then I'd have to
supply a screen, keyboard, pointing device, and battery. Sort of silly when
I have a lightweight laptop-format device with all that stuff already built
in, that cost very little to begin with.

Re: Best Audio Interfaces 2020?

You do not need an exotic soundcard for digital modes, most any will do.
The big thing to pay attention to is the noise level, which may or may
not be specified.

The soundcards reviewed at www.telepostinc.com is a good resource, but
those listed are for panadapter purposes, and need a wide bandwidth.
That wide bandwidth is not required for digital modes, but if you have
it, there is no harm done.

Many of the inexpensive USB soundcards will work fine for digital modes.
As I indicated, the noise floor will define which card is better, not
the bandwidth.

Soundcards for digital use (but not panadapter) can be found in the $25
and up price category.

Hi Wes,

You might want to look at the piece I wrote on the topic, which details
my testing. It was pretty rigorous. The USB interfaces I recommended
were equally good, decoded to much greater signal to noise levels, and
produced almost twice as many decodes as the sound system built into the
two T43 Thinkpads used for the tests.

Pulling out the weakest signals requires a lot of dynamic range if very
strong signals are present, and cheap A/D converters can have poor
linearity close to the low end of the dynamic range. WSJT-X uses 48 kHz
16-bit, theoretical 96 dB, real life more like 90. It's not unusual for
there to be locals 30-50 dB over S9 when the band is open, so every
little bit of dynamic range can matter when you're trying to work the
weak ones. All of this is why I started my search in the semi-pro audio
world.

One thing I differ with in the WSJT-X instructions is to set band noise
to 30 dB on the green voltmeter bar. That's fine for modes like MSK144
and ISCAT B, but gives up FAR too much dynamic range for modes like FT8,
FT4, JT65, and JT9.

Re: Best Audio Interfaces 2020?

I should have stated for KG6MZS that my computers do have audio inputs to the
internal cards.

And when I spoke of digital modes, I meant RTTY, the only one I seriously use.

Interesting. So what level do you recommend?

Thanks Wes. Yes, my older iMac has an audio input and a surprisingly good soundcard.

The reason I need the interface now is that my newer MacBook Pro doesn’t have a mic jack, so an external USB device is the only practical option. Ideally the USB interface would be USB-C, but I don’t think much will be lost in the conversion to USB A.

Thanks again to everybody who responded,

Sorry, forgot to finish that thought. Level should be adjusted so that
the green bar stays in the range of 70-75 dB with the strongest signals
filling the display, but never turning red, which indicates digital clip.

The same concerns apply to the decoding of weak RTTY signals.

Re: Best Audio Interfaces 2020?

I have two of these:

https://www.amazon.com/Behringer-U-Control-UCA202-Ultra-Low-Interface/dp/B000KW2YEI

I've used them on Windows, Mac OS, and Raspberry Pi ... just plug-and-play,
no drivers needed anywhere. Also use them with my sound system for
connecting my laptop to an analog audio mixer. The UCA202 also has an
optical stereo output, which I've used.

My experience using either Windows or Mac OS is that it's much easier to
interface with an external USB soundcard than it is using the audio in/out
jacks on the PC.

Nice device for not much money.

EDIT: Not sure that Amazon still carries it. Quick check showed that B&H Photo, and others, do ... price is around $28.
