[HamWAN PSDR] Ok, my numbers

[Bart Kus]

If it's a pre-wired unit like the DynaDish 5, you can't change 
polarities.  Will just need to live with the confusion.

That is pretty bad upload performance.  It could use some spectral 
analysis on the HamWAN side, and perhaps testing with another client on 
the same sector to find the cause.  I hope it wasn't caused by the 10MHz 
bandwidth change!

I don't have time to address this right now, so hopefully someone else 
can step in.

The download numbers look fine though.
