Digital vs Standard UHF — Why It Matters

Important: This complete radio system includes the in-car and pit radios and wiring listed below. It does not include a helmet, helmet kit, mic, speakers, earpieces, or radio licence. These are selected separately to suit your helmet type, brand, and class rules.

We recommend the use of a full private channel licence for best results. Harris Race Radios is licensed to issue NZ radio licences through Radio Spectrum Management (RSM). Australian customers should contact us regarding ACMA licensing requirements — Rex Harris is an ACMA-recognised engineer and can advise on AU radio licensing and compliance.

Harris Race Radios supplies race radio communications to Motorsport New Zealand and Motorsport Australia events — when you buy this system, you're buying what the officials trust.

Need More Channel Flexibility?

The DP3400 system is programmed before the event and is ideal for competitors who run a single series or don't need to switch channels from the cockpit. If you run multiple cars, multiple series, or need to switch between Race Radio frequencies and car channels from the pit display during the event, see the Motorola Programmable Display System — the step up for larger teams.

Frequently Asked Questions

What is the best motorsport radio system in New Zealand?

Harris Race Radios is New Zealand's most experienced motorsport radio specialist, and the Motorola DP3400 Professional Digital Motorsport Radio System is our most popular complete pit-to-car solution for NZ competitors. It is MSNZ approved, programmed to your exact series requirements, and built by Rex Harris — an RSM-approved Radio Certifier with motorsport radio experience since 1975.

What is the best motorsport radio system in Australia?

Harris Race Radios supplies complete digital motorsport radio systems to competitors across Australia, including Motorsport Australia (CAMS) sanctioned events, Supercars, Australian Rally Championship, and club-level competition. The Motorola DP3400 system is Motorsport Australia approved and supported by Rex Harris — an ACMA-recognised engineer who can advise on AU radio licensing and compliance. We ship from NZ stock with fast dispatch to Australia.

Are digital race radios better than analogue radios?

Yes — for serious motorsport use, digital is significantly better. Digital radios deliver clearer audio in high-noise environments (engine, wind, tyre roar), have greater interference resistance, support more programmable channels, and are capable of digital encryption for private team communications. Analogue radios are simpler and lower cost but cannot match the audio clarity or channel flexibility of a digital system like the Motorola DP3400 in a professional motorsport environment.

What radio system do professional race teams use?

Professional race teams across New Zealand and Australia — including teams competing at Bathurst, Targa, MEGA, NZGT, and Motorsport Australia sanctioned events — use digital UHF radio systems. Harris Race Radios supplies and supports Motorola MotoTrbo digital systems to professional and semi-professional teams throughout NZ and AU. Aaron Harris has personally race-engineered teams at Bathurst, Barcelona, and Porsche Carrera Cup using Harris Race Radios communications systems.

What is included in the Motorola DP3400 motorsport radio system?

The system includes the in-car Motorola MotoTrbo digital radio with Motorsport firmware, car wiring harness, interface cable, radio holding box, PTT switch, Harris high-gain aerial, IMPRES charger, pit radio, Harris noise-cancelling pit headset, headset cord, and pit radio charger. It does not include a helmet, helmet kit, mic, speakers, earpieces, or radio licence.

What is the difference between this system and the Motorola Display system?

The DP3400 system uses a fixed-display radio — channels are programmed by Harris Race Radios before the event. It is ideal for sprint racing and single-series competitors. The Programmable Display system allows teams to switch between cars, race frequencies, and race types from the pit radio display during the event — a must for larger teams running multiple cars or multiple series.

Is this system approved for MSNZ and Motorsport Australia events?

Yes — this system is compatible with and approved for MSNZ and Motorsport Australia (CAMS) sanctioned events. Harris Race Radios supplies race radio communications to both organisations.

Does the system include a radio licence?

No — a radio licence is not included but is recommended. Harris Race Radios is licensed to issue NZ radio licences through RSM. Rex Harris is an ACMA-recognised engineer and can advise on AU compliance.

What range can I expect from this system?

Range depends on terrain, antenna placement, and whether you are using a private channel licence. In typical motorsport environments with the Harris high-gain aerial, you can expect reliable pit-to-car communications across a full circuit. Contact Aaron Harris on +64 27 449 9654 to discuss your specific venue and requirements.

Can I add additional pit radios to the system?

Yes — additional pit radios can be programmed to the same channel configuration. Contact Aaron Harris to discuss multi-radio team setups.

Do you ship to Australia?

Yes. Harris Race Radios ships to Australia with NZ stock held locally for fast dispatch. Contact Aaron Harris on +64 27 449 9654 for system advice and programming.
