Send an ERF as Part of RXMT Operation (Special Operator Task 7)

5.5j.

This is not a normal operator task. It is performed only as part of an

DESCRIPTION

RXMT operation. When operators are required to perform RXMT

operations, it may be necessary for them to send an ERF to the distant

station in order to establish FH communications. Sending an ERF

requires the sending operator to change from FH to FH-M, with

associated risk to net sync time if the operator fails to return to FH

immediately after sending the ERF. The ERF procedure is known by all

NCS personnel, thus the RXMT operator should be able to obtain

verbal help if needed.
