Help & Advice

Racing radios

How far do racing radios reach?

Range depends on antenna placement, radio power and track conditions. Most 4-5 watt systems easily cover a typical road course. The rule of thumb is 1 watt per mile.

Are digital radios better than analog?

Both work well. Digital suits road racing and boat racing; analog is common in circle track and drag racing. If you need 100% clarity with no static, digital is the only way to go.

Can one radio work with multiple cars?

Yes. Many endurance teams run several cars on the same frequency, and our team-owner headsets can run two radios on one headset.

Ordering and support

When will my order ship?

Orders received before 2 p.m. PST generally ship the same day. Expedited orders need to be in by 1 p.m. to make carrier pickup. You will get a tracking number by email.

How much is shipping?

Shipping is calculated at checkout. Ground shipping is free on orders over $500.

Can you help me spec a system?

Call (805) 650-7223. Tell us the car, the series and how many people need to hear each other, and we will spec it. We have been building these systems since 1991.
