The Pluto and several other radios were built by Ranger for the Nochman Brothers in New York.Seems to me the Pluto was imported by an outfit who had no real incentive for quality control. That radio was smuggled into the country full functional. The "10-meter" fiction had not yet been put to work.
They imported and sold the Melika, the Saturn, Saturn Turbo and other non DX models.
No contact number, no warranty, no after sale support.
This was before Galaxy came along.
