Effective 12 May 2016, the Mission Support Network received two new frequencies. Therefore, all MSN frequency designators have been updated.

The actual on-air calling frequencies do NOT change. Only the designators changed, making MSI the Primary calling frequency designator, MSD the Secondary calling frequency designator and MSB the Tertiary calling frequency designator.

The AF MARS Frequency Matrix has been revised. It is now Revision 2, dated 12 May 2016. Per the Chief, AF MARS, the matrix cannot be posted on websites. Contact the MSN Manager if you need a copy.

The frequency for the Saturday morning Administrative net has changed to our new frequency, now designated as MSF for propagation testing on 21 and 28 May 2106.

* In Accordance With (IAW) AF MARS regulations and Communications Security (COMSEC), MARS Frequencies are considered, "For Official Use Only" (FOUO) and can not be published on web sites. Therefore, only the frequency designators are displayed.

All MSN frequencies are Upper Sideband and the "Dial" frequency is -1.5 KHz offset from the NTIA "Assigned" frequency.
