[linrad] Re: Linrad-02.00a


 Hello All,
I have linrad 2.0a working now with a single SB16 sound card on the slow WIN98SE 
machine 400 Mhz.
It is saving the par files fine now.
I selected the sample freq as 8000 Hz for the input but the program did not ask for the sample rate for audio output 
SB16 Wav out.
I have still the same problem that if I select "0", SB16 wave in, for normal mode ( single channel RX ) the program will not accept this ( error "stereo device does not support mono" )
This is, I suppose an error message by Leif, the linrad programmer ) Perhaps there is an answer 
why this message gets generated it does not happen in the linux versions )

Whether is it the 400 Mhz or not, but there is an instability
Every so often the spectrum gets written at a much higher horizontal speed ( time-axis ) and then drops back to the normal speed and a popping sound gets generated. at that time 
( no audio from rx supplied )

I will attach some of the parameter files this might help.
