The AF MARS Frequency Matrix was updated on 8 April 2017 to revision 9.
Effective 26 March 2017, the Mission Support Network replaced one frequency. Therefore, the MSN frequency designators have been updated.
Two MSN on-air calling frequencies have changed.
The old frequency MSH was deleated and what used to be MSI has been redesignated as MSH.
The new MSI is now the Primary Calling Frequency!
Due to interference on MSD, Frequency MSE is now the seondary calling frequency.

In Accordance With (IAW) AF MARS regulations and Communications Security (COMSEC), MARS Frequencies are considered, "For Official Use Only" (FOUO) and shall not be published on web sites.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.
MSA MSB Tertiary Calling frequency used at night when the Primary and Secondary calling frequencies are unusable due to propagation * MSC MSD MSE Secondary Calling frequency used at night and during the day if the Primary calling frequency is unusable due to propagation * MSF Admin Net Alternate Frequency MSG Admin Net Primary Frequency - Saturday morning. See the Nets page for times. MSH MSI Primary Calling frequency used during the day and other times depending on propagation * MSJ MSK MSL MSM
Word of Caution: Several of the MSN frequencies are very close to other MARS and various radio services frequencies. Be sure to only operate on the MSN "Dial" frequency.
* The "Calling frequency" designators and suggested times are listed on the Operations page. Be aware, these could change to the Primary, Secondary or Tertiary calling frequencies at any time depending on propagation and at the discretion of the Net Control Station.
