  • Notes
  • Shortwave converter covering 1.5 to 25.5 MHz. There is an ad in 1932 where the model 60 is shown besides the Sparton 16AW Allwave, which has this converter already integrated. There is not yet a primary source of evidence that the Sparton 60 Shortwave Converter was on the market in 1931, but we can presume that.
