While not a scanner, those Plectron alerting receivers were top-notch. When opened up, you could see that they were a quality product and, in service, very reliable.
Back in the day, I was one of the first officers in a start-up county EMS service with multiple stations. Since the budget was tight, we ordered a number of Plectron receivers and an associated encoder for alerting our stations. Apparently, it was a good decision, since many more Plectron receivers were still in service nearly thirty years later when I retired, even though our primary radio system had morphed into a Motorola trunking system. Given the quality of their products, I always wondered why Plectron ultimately went out of business.
