In 1966 I started my career as an R&D technician (took a leave from 
school for a couple years).  We built asw weapons (i.e. sonobuoys) in 
an old brick three story factory with a flat roof.  They test dropped 
the buoys over the side of the building 30-feet into a large vat of 
water, but the roof was the antenna test range.  There I ran tests on 
VHF antennas.  Not a very sophisticated range but definitely "hands 
on", real RF, real measurements.  An engineers calculator was a slide 
rule, no computers then; fancy computer simulation was unknown.

Mostly, I did troubleshooting of the engineering prototypes and 
finding fixes.  Those went back to the engineers to fine tune their 
design.  I quit that and returned to college in summer 1968 and 
landed a job with Hughes Aircraft in CA.  1971 found me working at 
Goldstone at the Microwave Test Facility also known as the "antenna 
range".  The rest they say is history.
