VHF channel 22A is the USCG working channel after which channel?

• A. Twelve
• B. Sixteen
• C. Eighteen
• D. Nineteen

Answer: (D)

VHF radio use for USCG relies on a two-step communication pattern: you start by contacting the station on a designated calling channel, then you switch to the assigned working channel for the actual conversation. The USCG’s primary working channel is 22A, which is monitored for routine communications. In many areas, mariners initiate contact on the calling channel and, once contact is established, move to the working channel to carry out the exchange. That’s why the best choice is that the working channel comes after the calling channel used to reach the USCG, which in this context is 19. The other channels listed are not the defined stepping-stone for USCG conversations: channel 16 is the international distress/hailing channel, and the remaining channels do not serve as the standard USCG working channel in this scenario.
