Special Containment Procedures:
SCP-7116 is contained within a 5km exclusion designated as Area-7116, as a response to the broadcasts originating from SCP-7116-A. To prevent the spread of SCP-7116 in the environment, four signal jamming towers have been established in each cardinal direction. These towers must be properly maintained at all times to ensure upkeep. Area-7116 has been designated as a signal-restricted site, with continuous monitoring to ensure essential radio equipment is rotated on a 24-hour basis to prevent contamination.
Authorized radio communications within Area-7116 are restricted solely for anomalous research. Approved alternative communication methods are limited to hardwired phone lines, with a receiver located at each major building within the area. In the event of an emergency, radio communication is permitted, albeit usage is restricted to only the passing of vital communication. All communication channels within Area-7116 are to be continuously monitored for signs of SCP-7116 interference. Contact between foundation sites must be made outside of the effective range of SCP-7116.
All equipment entering or exiting Area-7116 must undergo inspection for signs of contamination by SCP-7116. In the event that an object has undergone alteration by SCP-7116, the object is marked as an SCP-7116-C instance and will need to be secured within the onsite faraday cage to prevent the SCP-7116-C instances from propagating to other devices. The initial SCP-7116-C instance was contained within a faraday cage at Site-333, however after the construction of Area-7116, it was moved to the main containment storage onsite.
Intercepted SCP-7116 transmissions must undergo conversion into non-auditory formats prior to analysis. In cases where audio review is deemed necessary, exposure to the raw SCP-7116 broadcasts is limited to no more than 45 minutes within a 24-hour period. Research involving audio study requires Level 3 authorisation.
In the case of a scenario wherein SCP-7116 transmissions begin demonstrating personalized or targeted content, any personnel exposed to the transmissions are to be immediately removed from active duty and placed under quarantine for psychological evaluation. Individuals reporting continued perception of SCP-7116 transmissions in the absence of a contaminated device are to be treated as potential transmitters and isolated outside of the effective range within Area-7116 until symptoms disappear.
Due to SCP-7116-A's immobile nature, the entrance to SCP-7116-A is to be guarded by no less than two Security Personnel at a time, rotating in shifts of 2 hours each. Security personnel must be aware of potential SCP-7116-B instances attempting to exit the mine. SCP-7116-B instances emerging from SCP-7116-A are to be subdued, if in the event the SCP-7116-B instance displays hostile behavior, making non-lethal containment impossible, lethal force is approved and study will be conducted on the carcass.
Note by Doctor K. Parker
Reminding all staff onsite that SCP-7116 does not require deliberate tuning to be received through our communications and exposure may occur without direct interaction with communication devices, specifically through close proximity to SCP-7116-B instances.
If in the case a broadcast appears to address you directly, please contact your direct supervisor and have the incident logged in our report page in the main office. Do not attempt to verify the source of the broadcast.
Not all transmissions originate from within SCP-7116-A.

Description:
SCP-7116 is an anomalous radio frequency first detected in the vicinity of Mt. ████, Siberia, most commonly detected at 182.3 MHz, though the signal has been rarely observed manifesting across a broad and inconsistent range of frequencies. Whilst most commonly transmitted through radio transmitters and receivers, SCP-7116 is able to propagate through both active and inactive electronic devices and in rare cases, living individuals. Devices within 5km of the origin point of SCP-7116 will undergo progressive anomalous alteration after 24-72 hours of exposure, eventually gaining the ability to receive and broadcast SCP-7116 independent of power sources, signal range or hardware limitations. Altered devices are designated as SCP-7116-C instances.
SCP-7116 broadcasts consist of looping distress signals, using the voices of individuals confirmed to be deceased or missing within SCP-7116-A. Following continued exposure to SCP-7116, the transmissions begin to incorporate specified information relevant to individuals exposed to the frequency, including names, memories and emotionally significant events. This behavior is consistent in all SCP-7116 broadcasts transmitted through SCP-7116-C instances.
SCP-7116 transmissions have demonstrated the ability to influence behavior of exposed individuals, encouraging subjects to approach the origin point of the signal, or isolate themselves from others if within SCP-7116-A. Prolonged exposure may result in exposed individuals hearing SCP-7116 broadcasts in the absence of any receiving devices, and in extreme cases, producing the signals themselves. Living beings producing SCP-7116 frequencies are designated as SCP-7116-B instances.
SCP-7116-A is a mineshaft located on the eastern side of Mt. ████, Siberia. The entrance to SCP-7116-A shows signs of heavy erosion, it seems to be degrading despite the lack of water. The entrance leads into a tunnel with a steady decline at an angle of 28°. The tunnels of SCP-7116-A lack any sources of illumination, an external source of light is required for explorations into SCP-7116-A. After approximately 1.2km, the decline returns to a flat 0°. The tunnel forward contains several railroads, empty mine carts and other mining tools, implying miners from the 1840s once operated inside. Proceeding past this entry point, the spatial consistency within SCP-7116-A begins to degrade. Tunnels have been observed to shift in length, loop back onto themselves, or end altogether in nonsensical directions. Areas where SCP-7116 broadcasts the strongest tend to display non-euclidean geometry.
Exploration logs documented in the initial expedition of SCP-7116-A have logged the presence of enclosed spaces resembling residential homes, urban structures and other architecture within the mine itself. These environments seemingly correspond to locations of personal significance to individuals within SCP-7116-A. Structural inconsistencies have been noted, with structures commonly including altered layouts, missing features and distorted scale, suggesting these environments are reconstructed from information sources akin to a degrading memory.
Several areas within SCP-7116-A lead to large abrupt drops of indeterminate depth. These regions appear to lack any architecture and are currently believed to be void zones where SCP-7116-A has not yet fully manifested environmental constructs, supporting evidence being SCP-7116’s weakened signal strength within these zones.
Written messages have also been documented appearing along the walls of SCP-7116-A’s tunnels. These messages vary in content, age and composition, however much like the behavior of SCP-7116, they seem to update or change in response to match specific exposed individuals, with the contents of the messages becoming increasingly personalized during prolonged exposure.
SCP-7116-B instances are living entities believed to be the result of prolonged exposure to SCP-7116, most commonly found within SCP-7116-A. SCP-7116-B instances are humanoid in structure, with their physical traits varying significantly, with disproportionate limbs and features. Recorded footage of SCP-7116-B instances show irregular movement patterns, including delayed motion and desynchronization between audio and visual presence.
SCP-7116-B instances have displayed extremely coordinated predatory behavior, operating in groups to induce psychological stress in their targets. Much like SCP-7116-C, they function as transmitters for SCP-7116, with dissection of previous SCP-7116-B carcasses resulting in the discovery of a specialized mutated larynx capable of producing frequencies able to be picked up by radio devices within a 1km radius. SCP-7116-B instances appear to work off of a shared hivemind intrinsically linked to SCP-7116’s signal strength, as SCP-7116-B instances have been recorded ceasing motion within areas of reduced signal strength such as SCP-7116-A’s void zones.
SCP-7116-C refers to any objects contaminated by SCP-7116’s prolonged effects. SCP-7116-C objects produce the SCP-7116 broadcast at a consistent 62db. Affected objects show no need for power to operate, and will continue to broadcast SCP-7116’s signal until the object is physically destroyed or the internal components have degraded to an inoperable state. If an SCP-7116-C object has a digital screen, it will always display the radio channel “FM 182.3”. SCP-7116-C objects become transmitters themselves following contamination, capable of infecting other radio based electronics within a 1km radius.
Addendum-7116
On March 7th 20██, the Foundation communications team within 4.2km from Mt. ████ intercepted a transmission on Frequency Modulation 182.3. The transmission was a looping SOS message requesting help at the following [REDACTED] coordinates. The voice was that of Doctor ███, who six months prior to the transmission, had disappeared during a hike in the same mountain region. Mobile Task Force Unit Eta-11 “Savage Beasts” sent a squad of task force operatives to investigate the site.
PVT. Morrison was the only member to survive the expedition, the surviving video log can be accessed in the document below with those of at least Level 2 clearance. Included is the list of members involved in the initial investigation of SCP-7116.
