Radio | Antennas and Jammers
A radio world you build out of antennas. Tune to frequencies, run a dual-channel handset, raise antennas and jamming towers, hack rival towers to cut their reception, and put live stations on speaker zones, boomboxes and PA speakers that keep playing on their own.




















Overview
Build radio coverage with antennas and fixed towers. Players can use dual-channel handsets, disrupt reception with jammers or hack antennas. Optional broadcast stations play through speaker zones and placeable stereos.
What to expect
- A handset with two channels: talk on one, monitor another
- Signal fades with distance, indoors, underground and in storms
- Three antenna tiers players place, repair and pick back up
- Four fixed towers ship as backbone coverage across the map
- Jammers cut an area off the air, with a whitelist for allies
- A timed hack knocks a tower offline and can alert chosen jobs
- Job-gated stations with a DJ console and optional autoplay
- Map speaker zones, placeable boomboxes and PA speakers
Voice radio uses pma-voice, and the two-channel handset requires the pma-voice build included in the download. Music, speaker zones and stereos also require xsound.
Key Features
Dual-Channel Handset
Talk on a primary channel and monitor a secondary one at the same time, with separate volume memory per channel. Swap the two with one key, cycle your saved frequencies with another, mute players, carry a personal callsign.

Coverage You Build
Antennas project reception range. Bigger tiers cover more ground and take weather better. Step outside the coverage and your radio goes quiet.

Signal You Can Lose
Signal drops with distance, indoors, underground, and in rain and storms. Players have to watch where they stand.

Fixed Backbone Towers
Drop permanent towers around the map as core coverage, each with its own range, repairability and optional damage state. Includes the custom large antenna prop.

Player-Placed Antennas
Place antennas from items with ownership limits, optional health decay, repairs from kits and parts, and pickup that saves condition back onto the item.

Jamming Towers
Cut radio across a whole radius. Adjustable range, a draining power reserve, durability, and a frequency whitelist so allies stay on the air. Picking a jammer back up saves its remaining charge and condition onto the item.

Antenna Hacking
Run a timed hack with a success roll to knock a tower offline and lock it out, killing reception for everyone who relied on it.

Owner and Dispatch Alerts
A hacked antenna warns its owner and can ping chosen jobs with the location. Police or a response crew can roll out.
Live DJ Console
Authorised jobs go live from a stream link with a full console: add, reorder, skip, pause, shuffle and repeat, with one track fading into the next.

Voice Ducking
Lower music volume while the DJ speaks, then restore it after the announcement.
Optional Station Autoplay
Enable a looping station playlist for speaker zones and boomboxes. Live DJ playback takes priority, and autoplay resumes afterward.
Speaker Zones
Lock a square, yard or bar to a frequency. Anyone standing inside hears whatever is playing on it. Volume drops off towards the edge.
Placeable Boomboxes
Set one down and it either follows a radio frequency or runs a queue of its own, with shuffle, repeat and stream links players paste themselves. 3D audio that grows louder as you approach, plus power, volume and an optional battery.

PA Speakers
Point one at a frequency and it pushes whatever is live out to sixty metres, with no queue and no links of its own to manage. Stack a few around a yard or a compound and one station covers the whole place.

Ownership and Control
Stereos answer to their owner, with a config toggle for nearby public control. Jammers and antenna toggle or pickup accept the owner or an admin; antenna repairs follow their configured conditions.

Job and Duty Channels
Lock frequencies to specific jobs and require active duty, with named channels so police and EMS bands read clearly.

Persistent World
Placed antennas, jammers and stereos, ownership, conditions and lockouts all survive restarts. The airwaves stay exactly as players left them.
Configuration and Logs
Configure tiers, ranges, permissions and stations in the editable files. Discord webhooks can log channel joins, broadcasts and hacks.
Battery You Manage
Radios drain charge while tuned and shut off at zero. A warning fires when the battery runs low, and a battery pack recharges it on the spot.

Status Screen On The Tower
Antennas and fixed towers carry a small live display with condition, range and online or offline state. You can see what a tower is worth before deciding to repair it or hack it.

Hooks For Your Systems
Open server hooks fire on channel joins and antenna hacks for your XP or dispatch scripts, and exports let other resources start stations, pause autoplay or damage towers.
Static Creeps In
As your signal drops the people talking to you get thinner, then muffled, then robotic. The music fades under a bed of static at the same time.

Your Own Audio, No Internet Needed
Drop mp3 files into the resource and point a station at them. Sirens and alarms can loop, played from the resource itself with no stream and no external host.
