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.

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).

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.

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