In a perfect world, yes, I'd agree with you. It can be done all on one audio device. In fact, it can be done with a single mono full-duplex device. Just add a couple of CD4053s which switch the input and output between headset and radio along with the PTT. This is extra complexity in the audio interface. USB audio devices with stereo inputs are not nearly as common. Do you really expect the average user to be able to spot the difference from the packaging alone? I don't see a problem with using two USB audio devices provided the underlying hardware can support it. Most devices can, it's only in rare circumstances where they'll be a problem. It's just a matter of coding appropriately to handle that possibility, then people can apply whatever workarounds suit their application. -- Stuart Longland (aka Redhatter, VK4MSL) I haven't lost my mind... ...it's backed up on a tape somewhere. ------------------------------------------------------------------------------ Precog is a next-generation analytics platform capable of advanced analytics on semi-structured data.
