Has anyone played with these? http://www.dvsinc.com/products/usb_3k.htm

The Digital Voice Systems, Inc. (DVSI) USB-3000™ is the perfect combination of DVSI's AMBE™ Vocoder Technology with a USB interface. Connect the USB-3000™ to a Windows based PC's USB port, and users can encode and decode files, or develop a customized system to process real time speech.

Nope, but check http://www.youtube.com/watch?v=wShOLgW2tmI out, you can do the same thing with a $20 usb tv tuner. Ill be trying it out next week when i have a few days up my sleeve.

The big question is why bother? Theres at least 4 open source implementations of IMBE that I know of...

Why spend money on a dongle, which then you have to write code to send the data to and from the device, when all this has already been done with free software (OP25, DSD, etc)

Having said that, the worst thing about DSVI is that they don't bother with customer service t all.

I have contacte them previously to purchase development boards and they just don't bother replying..

DVSI - "Voice CODECs with arrogance"

Out of curiousity, what do you think this dongle is worth Matt?

DVSI quoted me $499US. Keeping in mind that you then need RF hardware and software to interface to it..

What do I personally think its worth? Maybe $10 tops. Motorola pay about $20 per radio in royalties to DVSI because they buy in bulk, and the scanner manufacturers get a similar price too. MBE based codecs are 30 years old now and DVSI have got the market cornered. Public safety vendors are literally over a barrel.

You can get an free open source library that does everything that dongle does:- https://github.com/szechyjs/mbelib or here https://op25.osmocom.org
