With your transceiver displaying the carrier frequency of phone signals, you hear a DX station calling CQ on 3.601 MHz LSB. Is it legal to return the call using lower sideband on the same frequency?

  1. Yes, because the DX station initiated the contact
  2. Yes, because the displayed frequency is within the 75 meter phone band segment
  3. No, the sideband will extend beyond the edge of the phone band segment
  4. No, U.S. stations are not permitted to use phone emissions below 3.610 MHz
