سؤال 18

Which of the following VHF/UHF band segments are limited to CW only?

  1. 50.0 MHz to 50.1 MHz and 144.0 MHz to 144.1 MHzپاسخ درست
  2. 219 MHz to 220 MHz and 420.0 MHz to 420.1 MHz
  3. 902.0 MHz to 902.1 MHz
  4. All these choices are correct

توضیح

CW may be sent anywhere the control operator is authorized, but the emission table only begins authorizing other modes at 50.1 MHz and 144.1 MHz. The bottom 100 kHz of each of those bands is therefore CW only. 219-220 MHz is a data-only segment, not CW only.
