Sure, we'd all like everything to always be free. But that's not reality.
DVSI has invested millions of dollars into the development of a state-of-the-art solution with AMBE. It is the successor to the IMBE chip that is used in the P25 protocol. It provides compression that is well beyond that of the open source solutions that exist today. And, even more appropriately, it fits in a handheld radio. But, if the Flex community doesn't want to do something that is currently being done with other VHF/UHF radios, then that is definitely their prerogative.

Imagine if you needed a dongle for PSK31, one for RTTY, one for WSJT etc. Personally I'd rather to see the SDR community advance the Free (as in freedom) state of the art than support solutions that are implemented in hardware solely to protect a proprietary codec. Just one ham's opinion. Cheers, Bill (kd5tfd) At 07:55 PM 6/1/2009, Woodrick, Ed wrote: >But it doesn't preclude the use of D-STAR.
