IRON NEST: Heavy Turret Simulator Teleprinter & Radio Intel
Calibration, radio channels, and reading orders before you measure.
In IRON NEST, intelligence arrives before steel leaves the barrel. The teleprinter to the right of your map table receives High Command directives, mission objectives, and spotter observations from the front. Radio traffic hums in the background —calibrate correctly and you hear everything that matters; calibrate poorly and you fire on garbled coordinates while useful messages pass unread.
This guide covers teleprinter calibration, radio monitoring, and how to turn printed intel into a reliable map mark for Map Measurement.
Role of the teleprinter in every mission
Nearly every fire mission begins with paper rolling out of the teleprinter. High Command uses it for TOP-PRIORITY directives, grid references, target priority, and sometimes restraint orders —do not shell a zone until civilians clear, hold fire until recon confirms, and similar operational constraints.
Friendly spotters relay what they see: troop concentrations, armor columns, enemy battery flashes, and course corrections after your previous shot. Treat spotter traffic as living updates to the same mission, not background flavor.
If you skip or misread the teleprinter, every downstream step fails. The First Firing Solution walkthrough assumes you have a clean order in hand before you touch the map.
Calibrating the teleprinter
Calibration is the first maintenance task on many missions. A miscalibrated teleprinter smears characters, drops digits from grid references, or merges two messages into unreadable noise. Follow the on-screen calibration routine when the game prompts you —typically adjusting sensitivity until test lines print crisp and complete.
Make calibration a habit at mission start even when the game does not force it. Experienced operators in the demo and campaign report fewer wasted shells when they never trust uncorrected output.
When text prints cleanly but coordinates look impossible —target behind your line, range of zero, grid outside the map —recalibrate before measuring. Garbled numbers sent to the Ballistic Calculator produce confident-looking firing cards that recon proves wrong.
Radio traffic and hidden channels
IRON NEST’s dieselpunk radio stack rewards attentive listening. Push the tuning dial far enough and unfamiliar channels answer. One stream carries High Command’s formal orders; another relays frontline spotter calls. Sometimes the most useful message is traffic nobody intended you to intercept —alternate-history Spain’s civil war produces chaotic airwaves.
You do not need to memorize every channel for basic missions. Do learn the difference between mission-critical prints and ambient chatter. When a spotter shout matches a teleprinter update, cross-reference both on the map before firing.
Advanced counter-battery work in Triangulation & Spotting depends heavily on timely spotter and intercept reports. Operators who monitor radio while waiting for calculator output spot enemy battery flashes earlier than those who stare only at the map.
Types of intel reports
Mission orders define objective, target class, and often ammunition guidance. Read shell recommendations here before loading the rack per Shell Loading & Gun Laying.
Grid and coordinate references translate directly to map marks. Plot them before using the measure tool.
Spotter corrections adjust aim after your shot or shift fire to a new threat. Update your map pencil marks immediately.
Recon summaries sometimes preview what aerial photos will show after firing. They prime you for Artillery Corrections when impact does not match aim point.
Operational constraints forbid firing until conditions are met. Ignoring them fails mission objectives even when your ballistics were perfect.
From intel to map mark
Read the full teleprinter strip before drawing anything. Identify target type —infantry in open ground wants high-explosive; hardened emplacement wants armor-piercing; screening missions want smoke.
Plot the target on the tactical map using grid references or landmark descriptions. If the order says “200 meters east of the church,” find the church, then mark east precisely. Vague mental marks cause vague measure lines.
Only after the mark is stable should you run the measure tool and copy bearing and range. Rushing to the calculator with unread intel is how demo players burn their requisition on the second mission.
Intel habits for demo and campaign
In the Demo Guide practice loop, read each teleprinter line aloud during pass one. Naming target type and constraint out loud catches skipped words.
During timed missions, develop a skim order: calibration check, objective line, coordinates, constraints, spotter addenda. Five seconds of structured reading beats thirty seconds of correcting a wrong shell choice.
When multiple messages queue, finish reading the latest spotter update before firing —old coordinates plus new corrections equal misses.
Troubleshooting garbled intel
Recalibrate the teleprinter first. If text is clear but content contradicts the map, trust physical terrain on the table and request clarification through mission flow if available, or wait for the next spotter print.
If radio static coincides with missed spotter calls, note the time and watch recon —you may need to fire without correction and adjust manually.
Frequently Asked Questions
Quick answers to the most common questions.
Why calibrate the teleprinter at mission start?
Miscalibration garbles coordinates and drops digits. Clean prints prevent bad map marks and wrong calculator inputs.
What intel comes through the teleprinter?
High Command orders, grid references, target priorities, spotter observations, and sometimes operational constraints like hold-fire conditions.
Are radio channels important in IRON NEST?
Yes. Tuning reveals High Command traffic and frontline spotter calls. Attentive monitoring catches updates that never print on paper.
Should I read the whole order before measuring?
Always. Target type, constraints, and spotter addenda change what you mark on the map and which shell you load.
What if teleprinter coordinates look wrong?
Recalibrate first. If text is clean but location impossible, compare against map terrain and wait for spotter confirmation before firing.
How does intel link to corrections?
Spotter reports and recon summaries after your shot feed the Artillery Corrections loop. Good initial intel reduces how many adjustment rounds you need.
