Best Radio's for Motorsport

The best type of radio for Motorsport is Digital Radio, using the FDMA method of transmission. Kenwood and Icom both use this system in their NXDN products. FDMA is a narrow band digital system that gives better rang and clarity ,due to its capability to reject electrical noise from racing cars.

What is DSP noise Cancelling

DSP noise cancelling is an electronic filter that recognises mechanical and repetitive noise like engine gearbox and even wind noise. the filter cancels this out but as human voice is a continuously varying pitch, the filter does not affect the voice. DSP is essential with Digital Motorsport systems as any amount of noise transmitted with the voice becomes mixed with it and cannot be recovered when the message is received. This will result in a garbled unusable message.

Best Pit to Car system

Pit to car systems using Digital NXDN technology give the best all round results when used in Motorspots. Kenwood and Icom radio units use NXDN but must also use DSP noise cancelling to ensure the system can cope with the high noise from racing cars. Autotel NX9000 and Race 600D fit most applications and budgets.
