M.A.R.S military affiliated radio services, does not publish radio frequencies, for civilian HAM use.
an affiliated member cannot divulge freqs, whether they are VHF ( 2 meter and 440 ) or low band ( HF ) , civilian HAM net
government military bands are restricted and encrypted and need special tuning and require MARS mods that are restricted
unless you are licensed ( affiliated ) .. you cannot get this info, digital or analog whether or not its modem or antenna reception.
about the NTSD, national traffic system(digital )..my father is 1 of only 2 TX/RX station operators in Michigan and has limited abilities within MARS, encryption/decryption or FL-digi and NTS .. my dad uses PacTor1 for Michigan and region 8 , for digital government
and military rebroadcasts and message transfers for all bands.
so unless you know someone inside, or affiliated with MARS and had a radio modified by them, your not going to get US Gov/MARS .. under normal circumstances there are a few exceptions
