Ciao,
Ok for The rx, i'll start with The vlf, i've
Got a nice edirol soundcard that samples up to 24 bit/96 khz.
I'll need some help in configuring spectrum lab since i'm a beginner in that
field.
The network, website and ftp are ready.
Regarding the sked i need The help of
Giulio I2FGT Because i'm a donkey in
CW ... But we can set it up. And hopefully i'll learn , sooner or later.
Thanks,
Giorgio
