Author Topic: External laptop microphone to Signalink USB???  (Read 1557 times)

This last week I finally "got around to" interfacing a 2m radio with echolink to make a linked station.  My radio is a Yaesu FT-2900R, my digital interface is a signalink USB, and my computer is a Toshiba laptop running Windows 7, 64 bit.  I had a few issues with echolink and windows properly recognizing the Signalink, but after some trial and error, my echolink link seems to be up and running with clear audio. 

Now for my question/dilemma.  I would like to be able to occasionally talk on my Yaesu radio, but the signalink ties up the microphone jack.  In order to do this, I have to unplug the signalink cable from the radio jack, and plug my radio mic into the radio. I know this is a rather strenuous process  Wink, but I got to thinking why couldn't I use the built in microphone in my laptop to convey the audio to the signalink.  This should activate the PTT circuit, and I would be good to go, and save myself the laborious task of hooking and unhooking my mic plug at the radio.  I've spent quit some time searching the web, and I haven't been able to come up with any software that can accomplish this rather seemingly simple task.  In addition, I would like to be able to use the spacebar (or another keyboard button) to act as a PTT switch, just like echolink does.

I'm just playing around here, and learning as I go, so I'm curious if anyone could point me in a direction?

Thanks much!

Wane,
Have you thought of making a small switch box just to switch from the signallink unit to a standard microphone? Just a thought...
