[HamWAN PSDR] Success!

The "undocumented configuration" is for any users of the Paine cell site 
attempting to use sector 1 (0 degrees, true north sector bearing).  SSID 
is HamWAN-0 there, not just HamWAN.  Feel free to expand your HamWAN 
scan-list with ssid=HamWAN-0 on frequency=5920, channel-width=5mhz, 

The signal levels Rob's referring to are measured in dBm.  Full 
throughput (about 10Mbit) stops below -71dBm, so the -46dBm is 25dB more 
than is needed.  A very healthy margin.
