  • Notes
  • The Interference Locator 230 has been announced in "Radio Retailing" as "Model 230, just brought out by the Filterette Division, of the Tobe Deutschmann Corp., Canton, Mass., has four specially designed stages of r.f. and two audio stages using three 232 tubes and three 230 tubes for detector and audio stages." More information you can read on the pictures. You can also see differences on the cabinet between this model 230 and later models. At least one shows a schematic - but there are used 4 '32 and tow '30 - and tuning range is known (here not yet): 550 to 1500 kHz - and that it uses rod and Loop aerials, bridge rectifier and meter indicate signal level.
