Not a pilot but when I retired from the FAA I was Technical Support of Navigation/Landing/Communications for the Pacific Northwest Systems Management Office. A fancy name for the guy they called if the ILS, VOR, TACAN, MLS, RCL, or any transmitter/receiver site couldn't get repaired by the field technician. I loved my job right up until it became more political than technical.
Thanks for all your work. I flew many ILS approaches in that region.
I myself have crossed the line and work as an inspector for the FAA now.
