If you're not seeing it then I must have it wrong. I'm trying hard but I think I'll get egg on my face. Page three says the gateway uses ulaw audio format to transfer linear digital audio to the repeater.
The dstar channel driver uses ulaw audio in digital frames too. I believe you'll need a dongle of sorts.
I feel like I'm stepping in some deep shit. Allstar network wasn't even in my vocabulary two years ago.
