All !
Thanks so much for your kind and enthusiastic and
extensive help.
There are too many responses to reply them all in
private.
But I now feel encouraged to wade into the
deep.
This week I have to make up my mind about
which Linux version.
I will try to install ( at least .. begin with... )
next weekend.
Fortunately, I got so many substantially valuable
advices.
Again, I am grateful for that.
I'll keep you
informed.
I do hope to get further support in this
adventure.
Two more questions :
A bit OT but I should know :
1:
Under which Linux version(s) does, just for
testing, the ordinary SoundBlasterLive ! ( not the digital, not the 5.1 ) sound
card work ?
Or is it version independent but driver dependent
?
Or depending or something else ?
Or doesn't this give a problem at all
?
I have reasonable NT4/5 knowledge and
experience, but not the slightest idea on Linux ( not yet...
).
I'll buy a 2 x 96
Khz card ( to get the best out of Linrad as I seemed to understand ) but
only after things are running properly here ever.
I run a P4 1.4 / 768 PC133 : enough
for the ultimate out of Linrad ?
I do not need a 96 Khz for other apps, just for
Linrad.
2 :
I am building the Brooks Shera GPS disciplined
frequency standard ( < 10^-11 for a 100
sec. dot ),
HP 10811 OCXO : phase noise : offset 1 Hz <
-100dBc.. ....1 KHz <-160 dBc.
I started this frequency standard project for
quite different reasons than Linrad.
However, does it make sense to use
this standard for LO ( 144 MHz ) in a DC front end for Linrad
?
Or is this overkill ( e.g. : doesn't the
SBL-1 or TUF spoil alot as to converter noise c.a. ? ).
I intend to experiment with EME QRSSS ( if another
nerd is also interested ... ) and I have the ( naive ? ) idea that short
term stability ( for very small FFT bin bandwidth during the dot
length ) and oscillator noise cannot be good enough.
Right ? Or overdone ?
Thanks for help.
Peter, PE1ECM.
