Is the Softrock TX audio bandwidth purely software constrained?
- 11/11/2012 14:00
I see people running ESSB audio rate the Flex SDR stuff as having
unconstrained audio bandwidth for transmission. With the Softrocks is
this purely constrained by the software used, or are there any audio
filters in the hardware? Thanks. Please don't turn this into an ESSB
flame war, I am merely curious as to the technical side of things, and
mainly use digital modes myself ;)

- Audio bandwidth is constrained by the sampling rate but that's not
going to be a serious limit; even 48KHz sampling is enough for
full-bandwidth audio. There are no filters in the design that
constrain audio response; it's all up to the software.
