Tigertronics SingaLink USB

Recently I purchased a SignaLink USB from HRO in NH to replace my Rigblaster Nomic. The Reason for doing so is that the SignaLink has a built in sound card. That means only one connection to the computer is required. It also Isolates the soundcard so I do not have to adjust my computers sound card every time I want to use digital.

Price (@ HRO): $99
Platfrom Installed on: Windows 7
Radio Used On: Yaesu FT-950
Software Used With: Ham Radio Deluxe, WSJT

When purchasing the SignaLink you can either get one to adapt to your microphone jack or your data jack (If you have one). Since the FT-950 has a RTTY/PKT port on the rear of the rig, I purchased the SL-USB–6PM. The 6PM stands for “6 PIN MINI” which is what the RTTY/PKT Port uses (Similar to a Mouse/Keyboard cable).

The box comes with everything you need to get going. Included in the box was the SignaLink USB unit,6ft  USB-A to USB-B cable (Similar to current USB Printer cable), 2Ft of Rj45 to 6 pin Mini din cable (From the Unit to the radio), 1ft Male to Male audio (stereo) patch cable, Jumper wires, Allen wrench, Software CD (Contains Jumper Diagrams and Various ham radio software) and Manuals.

The initial setup is very easy with the kit I purchased. Just plug the USB cable into SingaLink then into the computer, then plug the Data cable into the SignaLink’s RJ45 jack and plug the 6pin Mini Din into the rear (RTTY/PKT, DATA) Port of your radio.  Depending on your Operating system. The system will automatically recognize the SignaLink and install the default drivers for the sound card that is  in the SignaLink.

The software and radio setup could be a little confusing to some people. But it’s similar to any other interface that is out in the market. The only thing is is really different is that you will now have TWO sound cards  showing up on your computer (Your computers and the SignaLink). You will have to do some on software adjustments for the SignaLink sound card (Labeled “USB Audio Codec” or “USB Audio Device”) and you will have to modify your settings for each software that you use for communications. Tigertronics website provides a great amount of information on how to setup your SignaLink USB to your computer and will provide technical assistance over the phone\e-mail.

 

On the radio side with the FT-950 I went to menu # 51 (Data Out Lvl) and # 53 (Data V Gain) and changed the value to 90 to max out the levels. If I need to changed the RX and TX levels of the data port I can do so on the fly with the knobs on the SignaLink. I also changed FT-950 to display the ALC meter.

Now it’s time to pick a frequency and start doing some “Digital” Communications. I picked my favorite 14.070mhz. At this point I am adjusting the RX knob on the SignaLink to make sure I am not overdriving the DM-780 software. I keep my level around 40%. If you have the RX knob maxed out (turned fully clockwise) and you are getting less than 10% of audio then check the software settings on the “USB Audio Device” and the settings on your communications software (For example DM-780 has Attenuation level. That box should be turned off or at zero). If it’s still low then check your rigs Data Settings and max out the RX and TX gain

Once the RX is set, it’s time to start transmitting. Soon as you start transmitting adjust the TX knob so you see nothing on your ALC meter but the power is still at the level you set it at. The picture above shows that I set the power to 20 watts. in the PSK field you really do not need much power. I see a lot of people running high wattage which just makes it hard for others to communicate as they are causing QRM to stations near.

That’s It!

So far I am loving the SignaLink USB. My sound card is now free so that I can listen to music again. Windows OS sounds will no longer be transmitted (DING!), I no longer have to readjust my soundcard for digital. I can also use my microphone jack for it’s intended purpose; for plugging a microphone into. I can switch from digital to SSB in seconds!  I wish I purchased one of these with the radio.
