| The first step is to configure the Signalink unit properly in Windows. At first, it'll probably show as a USB sound device, but I changed the name to "Signalink", which is what you'll see in the screenshots here. | The first step is to configure the Signalink unit properly in Windows.

| * A <wrap hi>new setting</wrap> for the TX Ctrl is the sub-audible tone. Without this, the Signalink will transmit only when it hears a voice signal, which is why it needs some delays otherwise it would click in and out at the end of every word. But the sub audible tone keeps the PTT on until the person stops transmitting, even when they pause. This allows the delay on the Signalink to be shortened considerably (more on that later). \\ \\ <fc #ff0000>Update:</fc> I've had to disable this because I //think// it might be causing interference to the tone used by the repeater. I found that the tone transmitted by Echolink is 77Hz but the tone our repeater is expecting is 100Hz so it seems our repeater is not able to decode the two mixed together.{{ :howto:06sysop.png |}} | * A <wrap hi>new setting</wrap> for the TX Ctrl is the sub-audible tone.

| * I also disabled the DTMF so as to not conflict with the IRLP node. Users can still connect to Echolink on their phones and computers, but can't control it from their radio. {{ :howto:07sysop.jpg |}} | * I also disabled the DTMF so as to not conflict with the IRLP node.

| * Finally, I disabled the disconnect announcement. I find that it's more useful to know when someone connects than when someone disconnects. And during a net when multiple people come and go, the announcements can be quite disrupting. {{ :howto:08sysop.png |}} | * Finally, I disabled the disconnect announcement.
