Kevin, Geeks.com, and maybe others, sells a "USB sound adapter" for $4.99 ( http://www.geeks.com/details.asp?invtid=HE-280B&cat=GDT ) which works great here as the basis for an interface. Just make up an audio cable to your transceiver microphone input and just use VOX for PTT. If the audio level is too high, add a simple resistive attenuator as outlined in the DigiPan Help. Some transceivers need a 1:1 audio isolation transformer in that line, and some do not. This is about as inexpensive as you can get for an interface.

I like to build a lot of my own gear, allows me to learn new things along the way, it also saves a heap of money considering the prices some of the interfaces are costing. I have so far been using a soundcard and direct connection to my TS-480S/AT, with a small interface. Now I want to go a little further and build a slightly better one, but I want to build one with a usb connection so it makes a quick changeover. I have looked through Google with little success, so I am asking does anyone know where one could find information on building a USB sound w/interface? If not I will have to stick with my current interface. Thanks and A Merry Christmas/Season Greetings from Sunny NZ.
