Stand alone does not preclude software defined. I offer up as evidence the
Ettus USRP E100. It is completely stand alone but runs GnuRadio on an
embedded processor.
The ability to change the code running on ANY ASSOCIATED processor doing the
signal processing is what defines an SDR. It doesn't matter if it is the
user or the manufacturer. If the entire waveform processing can be changed
WITHOUT changing the hardware, and only changing software, it is most
assuredly software defined.
The K3 fits this description. It is NOT as versatile as the FLEX system in
this regard but it is an SDR. In the case of the K3, DSP chips are used.
In Ettus hardware, FPGA are used and either PC or embedded processor is
used. Flex uses the PC for its amateur radio equipment and FPGA and PC for
its commercial offerings.

Subject: [Flexradio] Misinformation about k3 being srd
All,
There are many hams that swear up and down that their K3's are software
defined. I try to explain to them that their k3 rigs are software enhanced,
but not truly software defined.
Many hams including some very bright engineers that are in the club still
think that their k3's are SRD.
I try to explain it that it is not srd as it can be run standalone, where a
Flex cannot.
I still get that glazed deer in the headlights look when I try to explain
SDR.
Any suggestions?
