    I have created this thread primarily to show the work which goes on behind the scenes at a typical repeater site in order to keep the equipment operating on your behalf, and the type of expertise provided free of charge by the repeater keepers!
    The repeater site shown in the videos is operated by Michael VK5ZEA is Port Lincoln, South Australia and is similar in many ways to our site, being remotely located on high ground and using a 5GHz network link to his home QTH.



    Here, he describes some of the problems he has encountered with his Icom ID-RP4000V UHF D-Star Repeater.


    The add-on board shown is a replacement for the standard connector within the Icom ID-RP4000V UHF D-Star Repeater (http://www.n5ebw.com/d-star-led-boards), which provides status LEDs for the repeater. He is using a "USB over Ethernet" module to allow him to remotely connect to the repeater over his network link to the site and monitor its status.



    Michael has also built a replacement for the ID-RP4000V repeater using Motorola PMR Radios and a node adapter with a custom-made board that talks directly to the ID-RP2C Controller.



    And installed at the VK5REX Repeater Site showing the cavities and pre-amplifier.


    Again a closer look at those cavities.
