سؤال 6

What is the required transmit frequency of a CW signal for channelized 60 meter operation?

  1. At the lowest frequency of the channel
  2. At the center frequency of the channelپاسخ درست
  3. At the highest frequency of the channel
  4. On any frequency where the signal’s sidebands are within the channel

توضیح

On the four discrete 60-meter channels the rules set the CW carrier to the channel center frequency; only phone, data and RTTY carriers may be offset 1.5 kHz below center. Placing a CW carrier at a channel edge, or anywhere its sidebands happen to fit, is not authorized.
