of the bigger issues with SDR's right now is with latency. There is some
slower tuning, a slight delay in received and transmitted audio, etc. I
believe it is quite at the level of other radios such as the K3. .
a radio, I am not sure. But I suspect that some of that might depend on
the baud rate of the radio. I have a TS-2000 set to 57600 baud and it
noticeably less responsive. I am not sure what the baud rate is on the
K3. And as far as booting up a computer, I work as a computer
