So how did you manage a S/N ratio of 47db then?  If that's normal for you,
how much do you want for your house?  :)

Dunno, I'd be very interested to see how a Courier performs from your site.
 With those levels and bandwidth, you should be seeing a 3429 symbol rate.

And with 3200 symbol rate, you won't see 33k6 anyway, as that requires the
3429 symbol rate.  3:640/305 is a good test, as Dave can just about spit on
his exchange from his back door, and even with my poor lines, I'm getting
33k6 connects with his Courier (usually 33600/31200).
