Former commercial broadcast engineer that got burnt out after 22 years of beating myself up trying to service four AM ttansmitter sites, one 3kw FM site, one 18 kw FM site, and one 100kw site along with four studio locations comprising ten actual studio rooms as well as five VHF/ UHF program repeater links all spread out over 120 miles from one end to the other. Now I work in a manufacturing facility four minutes from home. It's more mechanical than electrical but we do service and install electrically heated dies.
