This is the same method used in the 1930-1950 equipment.
  • Allows input of the full range of GB4000 frequencies
  • Now comes with a built-in frequency counter so you can accurately set your desired carrier frequency.
  • New maximum frequency range: When using the "RF Mode" 1 Hertz to 20,000,000 Hertz.
  • Compact design - 10.5" Wide X 17" Long X 10" High
