Sony CRF-5100 Earth Orbiter

RadioIntelligencer has an interesting article about the Sony CRF-5100 Earth Orbiter, which Sony produced in the 1970s. This receiver covered shortwave, mediumwave, and longwave; the FM band; the air band; and the "public service" band on VHF. This was a good radio. It was my father's purchase of an CRF-5090 Earth Orbiter in 1975 that got me interested in radio (the 5090 is the same radio as the 5100 except that it lacks the public service band). That 5090 is long gone, but I now own a 5100 I bought used last year. It was an enjoyable radio to use in 1975 and it still is today.
