• Notes

• Set imported by Apco AG, Zurich, identical to EC-1 made by Echophone USA, a brand of Hallicrafters. See also similar models under Paramount label: EC-1A and EC-1B.

  Three bands covering 550 kHz to 30 MHz. Bandspread; BFO. See also the assembly from APCO, Switzerland, as Echophone EC-1 A/B Skyrider Jr. It is to compare with the Hallicrafters Skyrider Jr. S-41G. The real story between these models has probably still to be detected and told. Maybe we should split this into two models - if some other sets will be found of the same kind.
