Question
What is the voluntary band plan restriction for US stations transmitting within the 48 contiguous states in the 50.1 MHz to 50.125 MHz band segment?
Answer Options
- A) Only contacts with stations not within the 48 contiguous states
- B) Only contacts with other stations within the 48 contiguous states
- C) Only digital contacts
- D) Only SSTV contacts
Correct Answer: A
Explanation
On the 6\text{-meter} band, the segment from 50.1 \text{MHz} to 50.125 \text{MHz} is voluntarily set aside as the DX (long-distance) calling segment. To maximize the chances of making international or long-haul domestic contacts (DX), stations operating within the contiguous 48 states are requested to use this segment only for contacts with stations not within the 48 contiguous states.
This convention ensures that the high-powered signals of local or regional stations do not block out weak DX signals that are trying to call in. If an L-48 station wants to call CQ locally or regionally, they should operate above 50.125 \text{MHz}.
