With your transceiver displaying the carrier frequency of phone signals, you hear a DX station's CQ on 3.601 MHz LSB. Is it legal to return the call using lower sideband on the same frequency?
A. Yes, because the DX station initiated the contact
B. Yes, because the displayed frequency is within the 75 meter phone band segment
C. No, my sidebands will extend beyond the edge of the phone band segment
D. No, USA stations are not permitted to use phone emissions below 3.610 MHz
