In using the MK OTAR procedure, there is considerable advantage if an Alternate NCS

takes the primary role in sending the OTAR. For example, an Alternate NCS can load the new TEK

into a second SlNCGARS radio, or into a TEK position other than that be used for the operational

net. This means that once the OTAR has been sent, the Alternate NCS can monitor

communications using both new and old TEKs, thus making it easier to bring in any stations that

missed receiving the initial OTAR.

Do not press [SEND] until Target NCSs are ready to press [RCV]. Then press [SEND]

within 20 seconds of directing them to press [RCV].

***

If distance or obstacles between NCS stations requires it, an RXMTstation may be used

in transmitting an MK OTAR. Transmitting and receiving stations must have the same KEK loaded

in channel 6. The fact that the RXMT link requires use of two net IDS does not change the

requirement to use the same KEK.

****

The Alternate NCS notes which stations still need the OTAR, keeps one channel on the

old TEK, and sends the MK OTAR to remaining Target NCS as contact is re-established, or at a

prescribed time.
