Designated Operational Coverage
EGNM. Delivery is normally on 121.805 with a DOC of 5 miles. Recently, the position has been temporarily moved to the standby Radar frequency of 125.380, which has a much greater DOC of 40 miles. Would it have been a requirement to reduce the power output of this frequency's transmitter in order to comply with the 5 mile DOC ? 121.805 is unused at the moment.
It might seem a daft question but these technical matters intrigue me! Thankyou.
