Warning:
These are the parameters I am
currently using with Linrad, version 3.21, and K1JT's program MAP65-IQ for
digital EME communications.
The optimum value of some parameters depends on the particular computing
hardware, at present in my case a Dual Core processor chip, Intel E3400 2.6GHz.
I am using Linrad only as a sensitive spectrum display and as input to MAP65-IQ,
so I have made little attempt to configure the audio output optimally.
Just because the values below work for me does not mean that they are optimal for a
different application using different hardware.
