Hello,

As part of confidence-building, I and one other person are going to 
attempt an 8 mile microwave transmission @ 5.885GHz tomorrow.  TX power 
will be just +10dBm.  30dBi and 32dBi dishes will be used. Projected RX 
power is -60dBm.  Receiver is sensitive down to about -115dBm, which 
gives us about 55dB of fade margin before the signal is undetectable.

This is the first long-range outdoor test to verify all the previous 
measurements + theory.  Assistance would be good, especially if you have 
a vehicle which can produce 200W or 500W of 120VAC.  Picture taking 
would also be cool, as would operation of UHF comms for coordination 
(alignment help).

Let me know if you'd like to help.   I'll likely leave my place around 
11AM and we'll go no longer than 6PM.

--Bart
