I am retired now but spent 43 years in Electronics Research and Development. I started in avionics, went to agricultural, medical & chemical instrumentation and analysis and ended up in the dark world of crypto and tempest computers. My hobby now is repairing and restoring the Hallicrafters SR series HF tranceivers.
