Andy, if you don't get any takers, I have an extra one I will be glad to drop in the mail to you - no charge. I purchased four to save on the per-unit shipping cost, with the expectation of giving them to others who would like to get on NBEMS. These things work just great and free up your computer soundcard for use by Windows. Just use VOX for PTT. 73, Skip KH6TY - Original Message - From: Andrew O'Brien To: digitalradio@yahoogroups.com Sent: Sunday, April 13, 2008 8:41 AM Subject: [digitalradio] Re: Anyone need a $6.50 soundcard ? --- In digitalradio@yahoogroups.com, Andrew O'Brien [EMAIL PROTECTED] wrote: I am about to order a USB external sound adapter for US$6.50.

Andy K3UK Hello Andy, I have used almost the similar USB sound adapter and made a modification to get a very high precision sampling rate. My module has a 12 MHz crystal and CM108 codec inside. It was only necessary to cut one of crystal wires and feed 3 V level from my double-ovened reference oscillator (by resistance division from 5 V TTL). 73 Matti/OH2ZT
Re: [digitalradio] Re: Anyone need a $6.50 soundcard ?
If your transceiver has no VOX for PTT, or you prefer to keep the mic plugged in, and you have no problem working with tiny SMT pinouts, the USB Sound Adapter can also be modified to provide an audio-actuated PTT output as well as audio in and out:: http://www.usbradio.org/usbfob.pdf This makes about as inexpensive a complete PSK31 interface as you can get! If you have any feedback problems, just add a Radio Shack isolation transformer in the transmit audio line. 73, Skip KH6TY Hello Andy, I have used almost the similar USB sound adapter and made a modification to get a very high precision sampling rate.

Andy, any takers on your offer. I am interested in the unit. Contact me off line to discuss your pendeng order.
