HARDware and software Infrastructure technical work group

 HARDware, ELECTRONICS, and software technical work group 

This KARO ECHO Work Group covers the repair, maintenance, installation, planning, access, and development of all the KARO ECHO Electronics Hardware and Software infrastructure, KARO ECHO served agency sites, and member sites. It is the physical/electronic network that our radio information travels on. 

Job Responsibilities/Purview

Technical issues include the development and maintenance of hardware, portable and fixed emergency power installations (training in the use of batteries, solar, and use of car charging system), ham & FRS/GMRS radio antenna equipment, and the regular maintenance and testing of portable and base antennas. The Infrastructure Working Group maintains a working inventory and a maintenance schedule. This team maintains coordination with corresponding agency site managers in order to arrange 24 hour access to equipment. The team works together with the Operations Work Group in order to identify and establish optimal operating locations and equipment. The Technical Work Group goes beyond the testing and maintenance of the physical infrastructure, but also  creative  development and design of new technologies, hardware, software, portable and fixed emergency power installations, radios, digital equipment, antennas, go-carts, masts, etc. 

This team will also help KARO ECHO members install, repair, and maintain their antenna, radio,  emergency power systems, and programming, as well as coordinate efforts with the KARO ECHO Training Work Group in their Elmering/Mentoring program.
