I'm working on an application that requires me to interface the discriminator audio output from a Radius to the Line In jack of a PC computer sound card. The RSS tech who programmed this radio also installed two leads carrying the discriminator audio from the rear multi-pin connector. I'm not familiar with the Radius' audio circuitry & am looking for some informed guidance on how to manage this setup correctly.
Thanks in advance!

Re: Radius/sound card audio interface question
I appear to have found the answer to my own question in a file right here at Batlabs:
The Maxtrac/Radius Series are 9600 baud packet capable. They do need a minor modification though. For RX, its no big deal, just take RX audio from PIN 11 of the Accessory Connector and swing JU551 to the (A) position (Flat RX Unmuted).
My Radius appears to have a black wire connected to PIN 7 & an orange wire to PIN 11. It looks like the job got done correctly for me!
