The category difference

Sent isn't aired.

Your licence asks you to keep a recording of your output as broadcast — what listeners actually received. A recording of the studio playout or an online stream can't prove that. It never sees a transmitter fault, a multiplex outage, or dead air on the actual signal.

◇ Playout / stream logging

Proves what you sent

Captured before the transmitter. If the mux drops, the encoder freezes, or you fall silent on air, the log looks perfect — and you can't tell.

  • Blind to transmitter & multiplex outages
  • Not, on its own, as-broadcast evidence
  • Monitoring usually costs extra
◆ AsBroadcast off-air

Proves what aired

A small box in your coverage area demodulates the live DAB or FM broadcast — the exact thing your listeners hear — and records it continuously.

  • Sees everything the listener hears — outages included
  • The as-broadcast source Ofcom expects
  • Transmitter monitoring bundled in one price
Stream or off-air

We record both. Only one of them is compliance.

Plenty of stations want their online stream logged — and we do that, properly, with no hardware at all. Just be clear about what it's for: a stream recording is excellent monitoring, but it isn't the as-broadcast evidence your licence asks for. If you need compliance, you need the box.

Needs the hardware Ofcom-ready

Record your off-air signal

A box in your coverage area demodulates the live DAB or FM transmission — the same signal a listener's radio receives — and records it 24/7.

  • The only capture that evidences what actually aired
  • Sees transmitter faults, mux outages and real dead air
  • GPS, on-box clock and device identity on every recording
  • RF and audio monitoring of the real transmission
  • 42-day retention and one-click Ofcom export
  • Your online stream recorded too, at no extra cost
From £22/moAbout the box →

Most stations run both. The box keeps your legal record; the stream feed sits beside it so you can see, side by side, whether what left the studio is what made it to air. And we never let the dashboard blur the two — a stream feed is labelled as non-compliant everywhere it appears.

How it works

Two ways in — pick what fits your station.

Start with an off-air box for full Ofcom compliance, or point us at your online stream to get recording and monitoring straight away — no hardware needed.

Ofcom compliant

Off-air recording

A pre-provisioned box with a DAB+/FM board captures what was actually transmitted — the real broadcast, not the studio feed. Give it power, an aerial and any WiFi. 42-day retention, GPS-stamped, gap-free.

Capture off-air

Demodulates your live DAB+ or FM signal in the coverage area.

Segment & retain

Gap-free segments kept for your full 42-day compliance window.

Monitor 24/7

Source loss, dead air and level faults — alerts the moment it happens.

Export in one click

Exact clip with schedule, music log and location — ready for Ofcom.

No hardware needed

Online feed recording

Point us at your webstream URL and we start recording and monitoring immediately — no box, no install, up and running in minutes. Great for listen-again, show archiving and stream health monitoring.

Add your stream

Paste your Icecast, Shoutcast or HLS URL — we connect and start recording.

Record & monitor

Continuous recording with dead-air, source-loss and level alerts built in.

Listen again

Browse, search and share recordings — embed a player on your own site.

Stream recording is not Ofcom-compliant on its own — it captures the studio feed, not the transmitted signal. For compliance, pair it with an off-air box.

The AsBroadcast recording unit The hardware A palm-sized box does all of this. One USB cable for power, an aerial in the box, and any WiFi to upload — home broadband, studio WiFi, even a phone hotspot. See what's inside and how to get one. Explore the hardware →
Monitoring, bundled

Know you're off air before your listeners tell you.

The same box that keeps your compliance record watches your transmission around the clock. No separate product, no à-la-carte add-on — it's in the price.

AsBroadcast monitoring dashboard: 24-hour uptime, loudness and true-peak readouts, a loudness trend chart against the R128 target band, hourly availability, and live status of each monitor.
Live dashboard — loudness, true-peak, phase and availability trended over 24 hours, 7 days or 30. Turn alerting off per stream to just track the data, no notifications.

Alerts, your way

The second your signal drops, falls silent, or a segment fails to arrive — we tell you. By email, or pushed straight into Slack, Microsoft Teams, PagerDuty or any webhook. Prefer to pull? Poll a read-only status API from your own monitoring or status page. Alerts open, resolve and acknowledge on their own — no noise.

Listen again — and let your audience, too

Scrub any moment of the last 42 days in the browser, and search what was said to jump straight to it — transcription built in. Drop a styled "listen again" player onto your own site, brand it to match, or publish shows as a podcast feed — all from the same recordings.

Online stream too

Point us at your webstream and we record that alongside the off-air feed — no box needed for the stream. Great for a side-by-side check of studio vs transmitter.

Automatic show tagging

Recordings label themselves with the show name — pulled live from the DAB programme data, or matched against a schedule you upload or sync from a calendar. Find "Breakfast, last Tuesday" instantly.

Tamper-evident evidence

Every recording carries a GPS location, an accurate on-box clock and a device identity — so the export stands up as proof.

Gap-free, always

Continuous 24/7 capture with buffering that survives a network blip. If a card bounces, a grace window keeps you covered.

Signal & audio, in detail

It isn't just recording. It's listening to the whole transmission.

Because the box demodulates your live DAB or FM off-air, it sees the reception exactly as a listener's radio does — and measures it, continuously, second by second. Two layers, one device.

RF · Reception

The signal itself

Is the transmission actually getting out — and getting out cleanly?

  • DAB bit-error rate (BER)Rising errors flag a mux or coverage problem before it becomes audible dropout.
  • Signal strength & lockEnsemble and service lock, RF level — know the instant the box loses your service on the multiplex.
  • Reception dropoutsMomentary losses on the off-air signal, logged and timestamped against GPS.
  • FM: RSSI, multipath & pilotFor FM stations — carrier strength, multipath distortion and stereo-pilot presence.
Audio · Content

What's on it

Is there real programme audio — at the right level, within the rules?

  • Dead air & silenceConfigurable silence threshold and hold — catches a jammed playout or an off-air fault fast.
  • Level: low & clippingUnder-modulation and clipping/over-level, so you sound right on air, not just in the studio.
  • Loudness (LUFS / R128)Integrated loudness tracking against the broadcast target — no surprises on the meter.
  • Profanity & keyword watchFlag watershed breaches and spoken keywords automatically, with a jump-to-moment link.
Coverage on the move

Drive your patch. Map your reception.

Switch a box into roaming mode, put it in a car, and it becomes a drive-test rig. As you move, it logs off-air signal strength, error rate and audio quality against GPS — building a live map of where your station comes through clean, where it fades, and where it drops out.

  • Prove your coverage area to Ofcom, funders or advertisers
  • Find the black-spots before your listeners complain
  • Same hardware, GPS on every box — no extra kit

Who it's for

Built for the stations nobody else priced for.

Proper off-air compliance has always been enterprise-priced — built for networks and regulators. AsBroadcast puts it within reach of a volunteer treasurer's budget.

Community FM / AM

Licence Condition 8

Keep your as-broadcast recording for the required window and produce it on request — without wiring up a studio logger you have to babysit.

Community DAB · C-DSP

Small-scale DAB

Captured by demodulating the off-air DAB signal in your coverage area — the per-station, as-broadcast capture point the condition expects.

Small commercial

Peace of mind, on a budget

Compliance evidence and transmitter monitoring in a single flat line item you can put in front of a board — no enterprise contract.

Ofcom & compliance

Straight answers.

Why off-air and not the studio feed?
Your licence requires a recording of output as broadcast — what was actually transmitted. A studio or stream recording is made before the transmitter, so it can't evidence a transmitter or multiplex outage, or dead air on the real signal. Off-air capture, taken in your coverage area, is the source that proves what listeners received.
How long are recordings kept?
The compliance tier retains your off-air audio for the full 42-day licence window, continuously, with no gaps. Retention accrues while your subscription is active — and a payment-lapse grace period keeps a compliance box recording so a bounced card never leaves a hole in your evidence.
What does an Ofcom request look like?
Open the dashboard, choose the date and time window, and download the exact clip in one click — bundled with the programme schedule, music log and the GPS location the recording was made at. If there's any silence in that window, the pack explains it: each gap is annotated with the transmission event that caused it and when it recovered (e.g. an off-air source loss at 03:14, restored 03:22) — so a dropout reads as a transmitter fault we caught, not a hole in your evidence. Your wider monitoring history stays private; only what's inside the requested window is included. No stitching files together by hand.
What hardware do I need?
A single compact box — a DAB+/FM receiver, a small computer, GPS and an accurate clock — that arrives pre-provisioned for your station. You connect power and an aerial; it registers itself and starts recording. One box covers one off-air feed; add a second for FM+DAB.
Is the online-stream recording compliant on its own?
No — and we say so clearly in the dashboard. Stream and listen-again feeds are genuinely useful monitoring value-add, but only an off-air feed satisfies the as-broadcast requirement. Nothing here lets you mistake one for the other.
