An update concerning MARSRADIO. An unclassified HF communications backup is reserved for active DoD and Federal Agencies. The net is still very active guarding its frequencies for calls. In the first half of this year, there were just under 2000 requests for phone patches, METAR/TAF weather, message, radio, and SELCAL checks. Additionally, there have been a few requests for updated Avian Hazard information. We were excited about the possibility of improvement in our global coverage with the peak of the solar cycle. Unfortunately, there has been a huge number of strong solar storms that reduce coverage. Some requests have been heard from the Western Pacific, Europe, and the Middle East. A REACH aircraft was 5 x 5 sitting on the tarmac in Iraq just the other day. The net can still make CONUS, international and DSN telephone calls. We are attempting to set up remote sites in the western Pacific and Alaska. This is a long and difficult process for a volunteer group with no DoD budget, but it is consistent with the volunteer’s desire to do as much as possible for communications backup. Those interested in using the phone patch service should take the opportunity to register patch information ahead of time. A “phone code” service was initiated for morale calls so personal information would not be disclosed over the air. Phone codes have also been issued for Official patches. Visit hfmars.us for the registration form. Keep your information private. Provide the operator with your phone code. They will enter the code and have their computer form populated with all the required information to make the call including alternate numbers. The net is known for using 13.927 mHz as a calling frequency. Keep 7.6335 mHz in mind for an alternate calling frequency, especially with solar conditions. Some MARSRADIO stations also maintain a guard on 4.457 mHz and 11.407 mHz. No answer on 13? Call on 7 due to the propagation being different. MARSRSADIO can be contacted through marsradioglobal.us/contact. To the active members on here, we hope that you have a safe flight and do not need us. We are there if you do.

The Air Force MARS Phone Patch Net has been operational since the Vietnam War. Hundreds of patches daily were handled through the early 80’s when bases starting closing their MARS stations. Today the net is tasked to handle DoD patch requests in support of transports, tankers, bombers and other aircraft and ground units handling routine weather, ETA/Customs, maintenance, etc. calls as well as emergency support. Morale calls are still happily handled. For more information see the website below. In the fall of 2014 the Chiefs of AF & Army MARS approved joint operations with AF and AR MARS stations participating. Chief Air Force MARS has approved a re-designation of the legacy AFMARS Phone Patch Network (aka - PPN) to the nomenclature of “MARSRADIO”. For operational reasons, amongst others, to offer nomenclature continuity to DoD customers / users this change has been made. Effective this time / date, PPN ceases to exist as an operational entity and is replaced as MARSRADIO. MARSRADIO is recognized as a global service authorized by the DoD that supports HF phone patch request and equipment checks (voice and SELCAL) as a backup to other communication services. If there are any questions, need more information, please contact the network manager directly. Richard Duncan, AFN6P (N6P) afn6p@marsradioglobal.us https://marsradioglobal.us Note: Propagation has been very poor lately and calls may be missed due to that. If unable to reach on 13.927 MHz suggest try 7.6335 MHz. Both frequencies are monitored.

The Air Force MARS phone patch net supports all DoD, Federal and State agencies providing HF radio to telephone interfacing. We have increased our monitoring due to hurricane Matthew and would like to remind pilots / operations that we are available to handle Official (and Morale) HF phone patch to DSN or commercial numbers. Specific information is in the Flight Information Pilot (FLIP) document. Please feel free to contact me or the net via https://marsphonepatch.net for any further information.

The HF phone patch net handles official (commercial or DSN) and morale patches as well as radio checks for DOD stations worldwide with good propagation conditions. Cost of the phone calls are covered by the individual member. The MARS Phone Patch Net website has been redesigned for easier viewing and includes an article on net procedures and operation. There is a training video available as well as a flyer that can be posted to provide information to aircrews. Questions or requests like access to the FOUO video and current frequencies can be made through the contact form. The request should include a .mil email address. The website is at https://marsphonepatch.net It is our privilege and honor to support those who serve our country. Richard / AFN6PP Mars Phone Patch Net Manager
