The equipment is in a weather proof metal enclosure. A wooden box covers it to keep the worst of the weather off and the temperature down in summer. The land line is on the left and the antenna cable and data cable is on the right hand side. This is a general view of the interior showing the WT in blue, top right hand corner audio speaker. Below the speaker is a PIC micro controller that does all the house keeping.
Bottom right is the solar regulator that controls the battery charging.
The 2 meter antenna is also on high ground and can just be seen above the rocks on the left hand side of the picture. An Icom Ham 2 meter radio is used for the radio access, the reason was that the sub audible tones and frequency could be easily changed on site. Just below the WT on the right hand side is a relay that switches the radio off at night and on in the morning. The micro controller always checks the battery voltage and will switch the radio off if the voltage has dropped below a pre determined voltage. This is important during bad weather allowing the WT to be accessed by phone only.
