21 EMCON Guidelines 1 RADIO ROUTINE Transmissions: RADIO ROUTINE. Any and all radio calls are authorized. ¹ Emitters: Any and all comm emitters are authorized. All non-comm emitters are authorized: PED, vehicles, generators, radars. Adversary: IMPROBABLE (45%) ES collections or EA. REMOTE (5%) threat of receiving fire (IDF). Scenario: Garrison or friendly country. Training, evaluations, and administrative movements. Note: Even during training, leaders should limit radio calls to mission-critical information. Standard for most amateur radio in a permissive environment. 2 RADIO ESSENTIAL Transmissions: RADIO ESSENTIAL. Mission-critical and emergency radio calls ONLY. ² ³ Emitters: Any and all comm emitters are authorized. All non-comm emitters are authorized. Emitters are SHUT OFF except when in use. Constant emitters (BFT / JBC-P, ALE / 3G ALE HF, and ANW2) OR (standard Meshtastic and Ion2G ALE) are restricted or OFF. Non-essential PED is OFF. Adversary: PROBABLE (80%) ES collections or EA. IMPROBABLE (45%) threat of effective IDF. ⁴ Scenario: Friendly, neutral, or hostile country. Contingency operations or pre-hostilities. Note: EMCON 2 is the desired standard for operations. Note: Emitters that are normally constant can be turned on for brief periods during sched- uled comm windows, for data exchange. Unencrypted analog transmissions generally not recommended at this level. 3 RADIO SILENCE Transmissions: RADIO SILENCE: NO voice radio calls. Text and burst data only. HF ideal. Wire. Emitters: Selected bands are restricted, receive-only, or OFF. Constant emitters (BFT / JBC-P, ALE / 3G ALE HF, and ANW2) OR (standard Meshtastic and Ion2G ALE) are OFF. Unencrypted UHF black gear is OFF. Non-comm emitters are restricted or OFF. Passive receivers—GPS, GBS—are restricted or OFF. Voice CFF / CAS are OFF. Adversary: HIGHLY PROBABLE (95%) ES collections or EA. PROBABLE (80%) threat of IDF. Scenario: Conflict. Enemy is collecting and targeting. Precision IDF weapons are in range. Note: Some units, executing fast-moving operations without key equipment, cannot rely on chat. Note: Constant-emitter features of JS8Call are not recommended at this level. Turn OFF au- tomatic heartbeats and replies. Passive receiving is generally okay, but make sure to verify that automatic transmissions are OFF. SCHEDULE short comm windows. NVIS antennas for localized HF operations ideal for reducing DF potential. 4 BLACKOUT Transmissions: BLACKOUT. NO radio calls—voice or data—are authorized. Emitters: ALL emitters are OFF. ALL radios, ALL PED are OFF. Batteries are OUT, generator power is off. ALL non-comm emitters are OFF. Vehicles are OFF. Lights are OFF. Adversary: NEARLY CERTAIN (99%) ES collections or EA. HIGHLY PROBABLE (95%) threat of IDF. Scenario: Conflict. Enemy is collecting and targeting. Precision IDF weapons are activated. Note: When missiles are inbound, units avoid being located, but cannot operate long at EMCON 4 Note: This level will be rarely used by prepared citizens, but is useful in the event of stra- tegic homeland threats such as enemy reconnaissance flights over US soil or for operation within military occupation zones when active collection methods are regularly used. Notes: 1. Specific EMCON actions taken under each option are defined by each unit for each operation. Restrictions on calls, nets, bands, and equipment are clearly defined by unit SOP. 2. Unit PACE plans specify alternate comms. 3. For emergency radio calls, leaders violate EMCON for safety, enemy engagement, or CASEVAC. 4. Adversary descriptions are ICD 203 language on the likelihood of enemy action. An actual attack or EA may not yet have occurred. Passive GPS Receivers are generally authorized at all EMCON levels, as long as all emissions from the device (Bluetooth, WiFi, etc) are turned OFF. Satellite communicators are considered to be Constant Emitters as most commercial satellite messengers constantly ping satellite networks. Emissions Control (EMCON) USMC EP EMCON SOP
