Re: [digitalradio] Building a USB Sound Interface
There's been some discussion about this on the linuxham list. If you buy a small USB hub, a USB-serial adapter and a small USB audio codec, you could pack them into a box with a single USB-B jack on one side for the computer, and a DIN, DB9 or whatever else you have laying around on the other side for the radio. I don't know about the availability or price of these components in NZ, but in the US you can get it all from geeks.com for under $20. -Joe, N8FQ On Sun, 23 Dec 2007 23:35:19 +1300 Gmail - Home [EMAIL PROTECTED] wrote: Hi All, Strange question I am sure, but please bare with me.

Re: [digitalradio] Building a USB Sound Interface
Kevin, Geeks.com, and maybe others, sells a USB sound adapter for $4.99 ( http://www.geeks.com/details.asp?invtid=HE-280Bcat=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.
