Nice one- they are _very_ local yo me. Shame the Maplin price is
lower. The Newcastle shop wasn't taking orders on Saturday as the were
selling like wild fire.
[BTW- Maplin tip- if you are near a shop, drop by with a order and
they don't charge P&P for the bits they don't have to be delivered,
regardless of the order value!]

I'm impressed!
At work I used what was supposed to be an expensive SVGA distrobution
amp and found it gave fuzzy, washed out pictures. It looked like
they's used 741 op amps instead of something with a little bandwidth.
600m is a long way- I've seen 100ukp passive baluns for Cat5, but
assumed these were only good for CCTV. Perhaps there is more bandwidth
in twisted pair than I thought.

Know the feeling well- there are about 6 projects on the workbench
with half-done documentation and WWW write ups.=3D20
I had discounted the idea of sending audio through UTP and decided to
put a PC next to the HiFi to play MP3, record science programs on R4,
etc.=3D20
Linux running BladeEnc MP3 encoder makes an excellent tape recorder-
set a job to record the favorites, and listen to them when you have
the time via a Samba mounted drive, Windows and WinAmp.=3D20
That way the audio moves around via Ethernet. UHF headphones as have
started appearing in Dixons seemed annother alternative.
It looks like you know a better way!
TTFN,
James
