Answer 1

The most correct way to write this would be U.S.,

Step-by-step explanation:

I have a few opitions which are all techincally grammaticlly correct.

First, the radio signals came from the United States; then they came from Canada. (More formal)

...came from the U.S. but then.... (also grammatrically correct)

...from the U.S., then from ....
