Q & A

 

 

This is how the generator is transported up the mountain to the wind and solar repeater site. Of course there is only so far the wheelbarrow can go, after that, the generator must be carried. The battery charger rides in the wheelbarrow too! A generator is a necessity when performing maintenance on the batteries.

      The bottom right shows the tower base as the cement was  just poured. This base is for the windmill at SNS, a tilt over hinge sits on top of the bolts.

   Bottom left picture is the hand winch with the "fit any tree" mount that was a perfect solution to erect a fifty foot tower. Luckily some small diameter trees where within close range of the tower.

 

               

To the right is the winch attached to two trees and shown supporting the windmill tower. The five men holding the tower are not shown! The first few seconds after a tower is stood up is a very exhilarating feeling!

 Bottom left and right show the Astron power supply with the back up batteries underneath, picture on the right is the inside. Notice the "tested" message, how reassuring! These supplies are built like a tank and weigh as much. Of the three supplies that are in operation, all have minor differences, Astron certainly reads the comments concerning improvements that are posted in the ham radio groups.

 

 

 

 

 

 

 

 

 

 

To the left is an interface box that had a keyboard placed upon it. Even though it is temping to say 101 switches are required to operate the interface, unfortunately that is not the case. It is prudent to build an interface that allows all connections to be accessible.

 The picture to the right shows the tower and wind turbine at SNT, notice the heavy guage wire, voltage drop is a concern. This tower has a tilt over base, it tilts away from the camera, and to the right, which makes maintenance a lot easier. Remember most towers are built to reduce wind resistance, wind turbines create wind resistance!

  This is the battery bank at SNT, series and parallel connections supply the correct voltage and current. An one hundred amp breaker is used for the main cut off. Heavy gauge wire is connected directly to the repeater rack, ten guauge wire connects all the equipment to the rack breakers.

   Without the parts, there can be no repeaters! It is scary to think about how much money is actually spent on inventory. Radio connectors on the left, and controller connectors on the right.     

 

Bottom is the hinge base during final adjustments for the SNT wind turbine. Cement is poured with the studs in the correct position, the big test comes when the base is set onto the top.
