For a while, Kenwood was known as Trio. The Trio brand was sold at private stores like Radio Shack and in many countries in Europe. The company switched their name to Trio-Kenwood later and then eventually dropped Trio together and became known as the Kenwood brand that we all know and love today. It was in the early 1960s that Kenwood called themselves trio. Radios made during this period are a great find for any serious collector or for anyone who wants to take a trip back in time with a great old-timey radio system.
