TOWERLESS

Radio runs the operation.Towerless keeps the record.

An airport-owned operational record layer for 4,500+ untowered U.S. airports.

02Problem

Airports answer for radio trafficthey can't replay.

Who Pays: Municipal & County Sponsors
County, city, or airport authority. Used by the airport manager.
The Problem: Disputes Without a Record
Complaints, insurance and board inquiries land on the airport — with no searchable radio + aircraft timeline to review.
The Cost: Reconstruction Time
Staff rebuild each event from memory, calls, tracks, and cameras. Professional runs $2,148/yr — about a few days of that work.
UNTOWERED AIRSPACE — NO RECORD
Most public-use facilities operate without a control tower.

03Product

Connect the node.The record begins.

Place it at the airport. Towerless passively listens to configured public radio channels, matches supported aircraft data where available, and builds a searchable operational timeline.

Why now: consumer-grade SDR hardware and on-device transcription have only recently made this possible without new airport infrastructure.

CAPTURE

Configured public, unencrypted radio calls. No transmission. No interference.

MATCH

Radio calls matched to aircraft identity and position where supported. Confidence-scored.

RECORD

Timestamped, searchable, exportable operational timeline. The record that did not exist before.

04How it Works

From radio trafficto an auditable timeline.

CAPTURE
Capture public airport radio.
MATCH
Match aircraft context.
TIMELINE
Build a searchable timeline.
EXPORT
Export the operational timeline.
Memory is not a record. Towerless creates one.
Every radio call is timestamped, matched to aircraft context, confidence-scored, and exportable.
05Why Towerless
Current tools capture pieces.Towerless creates the record.
What Airports Have Today
Human Recollection & LogsManual and fragmented.
Public Audio FeedsThird-party audio only.
Aircraft TrackingPosition without radio context.
Standalone RecordersAudio without correlation.
Enterprise ATC SystemsBuilt for staffed towers.
Product concept — target dashboard, in development
TOWERLESSCreates an airport-owned operational record from public airport
radio activity and supported aircraft context.

A recorder stores audio.
Towerless creates a timeline airports can search, review, and export.

06Technical Progress

Filed. Demonstrated.
First proving site pending.

Towerless has been demonstrated on public aviation radio traffic, including a receive-only setup at the April 25 Woodward Field airshow, and is being refined through founder-operated SDR/radio testing. KCDN Woodward Field is the planned first 24/7 proving site, pending county approval.

Currently here.

1. Patent Pending

Provisional filed May 15, 2026.

2. Early Demo

Receive-only setup demonstrated
at the Woodward Field airshow, April 25, 2026.

3. Technical Validation

Founder-operated SDR/radio setup
refining the pipeline on public aviation traffic.

4. KCDN Proving Site

Planned 24/7 airport node,
pending county approval.

5. Production Hardware Next

Round funds standardized
field units.

Founder–Market Fit
Roman Lepekha — Founder & CEO, Air Signal Labs

FAA Private Pilot, Honorary Commissioner, Kershaw County Airport Commission, 2023–2024, appointed at 16. Led an Eagle Scout airport-awareness project at Woodward Field — the same airport that is now Towerless's first proving site. Built Towerless after seeing that critical airport radio activity had no durable, airport-owned record.
