I am a Radio Telecom Systems & Field Engineer  with over twenty-five years experience in systems design & integration, commissioning & performance/acceptance testing, and hands-on trouble shooting of a wide variety of complex electronic systems . My emphasis has been on HF/VHF/UHF land-mobile radio systems and wireless data systems. (See resume below.)  My experience ranges from high-power AM-FM-TV broadcast systems, through land mobile voice, data and AVL systems,  to low-power 802.11 wireless LAN devices.   

I worked for the County of Los Angeles Department of Communications for many years.  There I developed an automated radio mapping system used to perform numerous drive tests and radio coverage surveys for the Sheriff and County Fire Department radio networks.  This system combined several pieces of commercial off-the-shelf hardware with personally-developed interface hardware & software, and MapInfo GIS software.  Click Here to see details of this system.

Further, I investigated complaints reported by Sheriff, Fire, Public Works and General Government radio users, tracked down sources of interference, and recommended system changes and updates.  I also worked on developing “stealth” antenna installations to overcome local objections to visible antennas on various county facilities. 

I also set up and demonstrated a prototype GPS-based AVL (Automatic Vehicle Location) system for the LA Sheriff’s Department, using inexpensive off-the-shelf components.

I spent many hours advising personnel in the Sheriff’s and County Health Services Paramedics departments on radio-related issues.  I always enjoyed interpreting and explaining complex technical issues, both orally and in written form, to non-technical management and supervisory personnel.
