What indicator is required to be used by US-licensed operators when operating a station via remote control and the remote transmitter is located in the US?
/ followed by the USPS two-letter abbreviation for the state in which the remote station is located
/R# where # is the district of the remote station
/ followed by the ARRL Section of the remote station
No additional indicator is required✓Correct answer
Explanation
The rules require the station's assigned call sign and merely permit optional self-assigned indicators; nothing ties an indicator to where a remotely controlled transmitter sits inside the United States. Remote control changes where the control operator is, not how the station identifies, so no state abbreviation, district numeral or Section suffix is called for.
