Working Great for me  Time owned: more than 12 months
I like having the external knobs to adjust sound levels. Much easier than digging through menus. It is working great for all modes I have tried it with. Very easy to set up and operate.

Signalink USB and Linux  Time owned: 0 to 3 months
Purchased the Signalink to replace the defective SCU-17 (CAT interface broke) connected to a Yaesu FT-450D. This freed up my computer sound card. The Signalink has great frequency RX response. Was able to adjust ALC and not over drive. The PTT light did not light but not a big deal for me. The soundcard chip (PCM2904 was easily detected by my Mint (Linux) OS. Also suggest purchasing the 6 pin jumper to prevent wiring errors.

Alright... Ya got me.   Time owned: 0 to 3 months
I've long held the opinion that the entire point of having "soundcard digital modes" in the first place was to preclude the need for additional interfaces. Anyone who struggled with getting a Baycom TNC to work in lieu of writing a check for a KAM, or anyone who understands that RTTY once consumed oil from Western Electric can see what I mean. So, for the last decade I restricted my concern to PTT considerations and let the stock motherboard sound handle the rest. I saw no need for another unit.

Having recently gravitated to FT8 I started operating more digital than ever. I bought a new radio (FT891) and made some cables to handle the CPU connection. I heat shrunk a few chokes on them and went at it. Everything seemed to work fine, but I noticed strange behavior in my power meter. Tuning a second radio monitor my output, I realized I had a major ground loop problem, and it wasn't giving up easily.

I had been contemplating buying a SignaLink to make it easier to get on the air with a Mac I use for music production so I broke down and bought one hoping the isolation might solve the PC noise problem as well.

It did. As others have pointed out, it makes things much easier with cleaner output than by internal sound interface alone. I realize that some of the isolation-only solutions on the market might have solved the problem, but the SignaLink handles everything with much less complexity. As reluctant as I was to make the investment, I'm glad I did.

Easy  Time owned: more than 12 months
I own two. They work very well with several radios I use them for:
- 817ND
- 897D
- 480SAT

From SSTV to PSK31 it gets the job done.

Works well then fails.  Time owned: more than 12 months
I have had very good success with digital modes using a signalink USB. I purchased mine in 2008 about a month or so before QST's review of it. I used it with Yaesu FT-857d, FT-817nd, FT-847 and FT-450. In September 2011 the Signalink had an issue and killed the control board of my FT-450 (a $300 repair plus shipping both ways) also the Signalink would not transmit any audio to my other radios. Eventually I sent it back and paid for a new board ($80 with shipping both ways). August 2017 the Signalink faulted again. This time it has taken my HP Laptop (bad motherboard, replaced by HP), my FT-450 (will not power on and fans run on high, probably another bad control board) and the Signalink itself is stuck in transmit when power is applied. At first I thought maybe lightning, but all power(breaker panel) and antennas were disconnected. The Signalink is the common denominator and I will not purchase or even recommend anything else from Tigertronics. This product works well but can cost a lot in the long run.

Excellent and reliable  Time owned: more than 12 months
I've had this Signalink USB hooked up for 8 or 9 years now, using it with my Kenwood TS-570D/G and TS-440S/AT radios. Works well for both. I bought the headers when they came out a few years ago, which made it much easier to swap between radios.

The unit has been very reliable. It's a "set and forget" piece of gear. I use Debian Linux, and there is a warning on the website about using it with Linux. However, it was easy to set up and has worked well through several Debian upgrades.

Works Great With Mac  Time owned: 0 to 3 months
I purchased the Signalink USB about one month ago to use with an Elecraft KX3 and a desktop iMac. The Mac is running the current Sierra version of OSX.

The Signalink works great... my main operating modes are JT65 using WSJT-X and PSK31 using Flgigi. Setup was easy and there was no need to manually download any drivers.

Here's a tip if you will be using the Signalink USB with a KX3... order the Plug & Play jumper module. Not only is it easier than manually placing the jumper wires, it comes with a voltage blocking capacitor so you don't need to turn off the radio's microphone bias setting each time you switch between SSB and digital mode operations.

Works Great!  Time owned: 6 to 12 months
After checking out several interfaces for HF digital modes, I selected the Signal Link USB. Arrived well packaged and documented. Had it up and running in very little time. Had a bit of a problem with Windows 10 but that was my unfamiliarity with 10. I think this is a very good interface for the money.

Win10 is OK  Time owned: more than 12 months
Had mine on a Win7 machine. When I upgraded to Win10 the SignaLink-USB kept right on working with no changes.

The noise issue some complain about comes from the computer via USB power. The amount of noise is dependent on your computer. Mine was low and the mod made no significant difference.

Perfect  Time owned: 0 to 3 months
Currently using a windows 10 machine with an Icom 756 PRO-III and have absolutely no issues. Does everything I wanted it to and more. You will not be disappointed with this product.
