10 GHz - Reducing the Uncertainty Factors for Microwave QSOs

There are many factors that tend to introduce uncertainty when attempting QSOs on the microwave bands. Some of these include:
  • Precise aiming (Azimuth and Elevation) of your highly directional antennas.
  • Precise control of your transmit frequency.
  • Precise control of your receive frequency.
  • Finding very weak signals whose frequencies are are drifting up and down the band.
  • Determining your relative transmit power at the antenna output.
  • Determining your relative MDS (Minimum Discernible Signal) at the antenna input.
  • Providing a 50 ohm reference noise source for comparative noise measurements.

These uncertainty factors are especially difficult to solve for tower mounted microwave systems which require remote control/monitoring of their status and performance. 
This is the topic of the Aurora/2012 presentation (see below).


     What's inside the "black box"?
    This is the subject of a presentation and demonstration scheduled for the NLRS Aurora Conference on May 12th 2012 in the Twin Cities, MN. A summary will be posted here after the conference. You're encouraged to attend in person to hear all the details, ask questions and fondle the prototype.
