Army My Army MOS was 98G, Electronic Warfare Voice Intercept. I was also supposed to be a Korean linguist and understand North Korean military chatter. Fortunately for me, all this kept me around the Monterey Bay in CA for most of my enlistment, one of the prettiest places in the country. Yes, the US Army spent about a year teaching me Korean and never sent me to Korea. After attending the Defense Language Institute, I was stationed at Fort Ord, CA. The hi-tech equipment in the picture consisted of a radio receiver, direction finding processor, a signal analyzer/oscilloscope and a tripod mounted antenna array. Three briefcase size pieces and the antenna weighed over 100lbs (batteries not included!). As part of a “Light” infantry division, usually 3 of us would hump this, plus our regular weapons, ammo, food, water, batteries and maybe a sleeping bag up a hill, mountain or other high spot that gave us clear line of sight towards the “enemy”. After setting up the equipment we would spin the dial looking for traffic and report Frequency, Azimuth and tactical information. The receiver was basically FM and when we had downtime, or were just bored, we might wander down to 900Mhz and listen to whatever we could find. Most calls were in the clear without even simple inverted voice scrambling. We were told it was “illegal” to listen to private citizens’ conversations, but we entertained ourselves many a late night while on an exercise. I’m sure the NSA was listening then as well.
