Maybe my question is not clear: I want to know what command can be operated to make the Pin on the CM108 chip to activate? What command does Asterisk run so that it activates the PTT button on the USB fob? On Sat, May 9, 2015 at 8:10 AM, Corey Dean <n3fe@repeater.net> wrote:
You could just invert it using a pnp and a 10k resistor.

Is there a way to tell pin 13 on the CM108 sound card to activate High vs Low?
Although this is off topic, I thought maybe people here would know:
I want to use a USB sound FOB for APRS with XASTIR, and I want to see if I can use a cheap sound card instead of a TNC. If nothing else, I will have to use a VOX circuit, but it would be cool if I could script XASTIR to tell the USB card to activate high/low when it PTT's.
If anybody has experience with XASTIR, do you know if you can even use sound cards in it? Or does it have to be a TNC.
