Zebulon RPTR Site Updates...

3/17/2008 - The new Zebulon repeater site is now up and running. The 442.40+ repeater, a commercial 
repeater, and 2 of the packet nodes (W4RAL-7 on 147.54 & K4RTP-7 on 145.77) are now on the air. Work is underway to get the 29.620, 53.07, & 224.8 repeaters in the cabinet and running again.

The pic on the right is the re-installed cabinet from the old site with a fresh coat of paint, 3 new blowers, a new battery backup system, dual chargers, full-time 12vdc supplies, and part of the equipment installed. The battery backup supplies 175 A.H. of power, with the ability to dump over 1000 amps at surge.

Steve KD4WIW designed and installed a stainless steel top-hat on the cabinet, to keep water off and hopefully reduce the possibility of a leak that could allow water to enter from above the equipment. The cabinet is sealed at all openings, with the exception of three outward-blowing fans at the top and bottom, and 1 filtered inlet near the bottom of the cabinet. Feedlines are brought around and in through the bottom of the side-mounted enclosure seen on the RH side of the cabinet in this picture.

Below is a pic of the backup batteries...

Lastly, for now, here's a pic of my faithful helper... Bridgette!
