RE: [Discuss-gnuradio] USRP2 Price

[Marcus Leech]

The best price/performance ratio is the ICRON Ranger 2101 or 2104.  It's
$350.00 or so,
  but I've been evaluating one, and it works just fine at 150ft--I have
no need to go
  further, but the unit will work up to 100M.  I'm using Cat5e FTP (foil
shielded twisted pair), to
  reduce unwanted emissions, since I'm basically running Cat5e all the
way to the feed at the
  SBRAC dish site.

Cheers

May I ask where you found the USB extender? I'm having trouble sourcing
anything that runs that far and can handle 480Mbps.
