Re: Faros + SDR
- Theres a point where I'm going to have to just bite the bullet and
start soldering. The I'll get my eyes lasered so i can see again!
thanks for the advice though.
I've got a v9.0 kit which I'm hoping to use. There are a few people
who've got a seperate board for swithing centre frequencies but I'm
thinking this might not be necssary if the centres are set to the
ncdxf frequencies. I undertsand that even if a 48kHz soundcard is
used then it will not be too hard to set it up.
