Easitalk (easytalk) is a feature of NGT transceivers that removes noise and interference from incoming voice signals. Easitalk works by applying Digital Signal Processing (DSP) techniques to incoming voice signals. These techniques are similar to those used with digital mobile telephones and satellite telephones.

Easitalk is simple to use because it is integrated into the transceiver - it is not in a separate unit. No tuning is required, just an on/off control.

Listening trials indicate that Easitalk outperforms other noise reduction products, and it has been successfully trialled with a wide range of languages.

By integrating speech processing within the transceiver, Codan has not only made speech processing more effective but, more importantly, has made it useful in the hands of the user. For the first time, mobile users will now be able to enjoy the benefits of noise reduction technology.


Hear the difference ... The same transmission was received by two HF tranceivers, one with Easitalk enabled and the other, without. Both transceivers were connected to the same antenna.


No Easitalk

This is typical HF radio containing both voice and a large amount of background noise. The average signal (shown as a lighter colour) is fairly even indicating that the voice signal is not any more prominent than the background noise.



Codan advanced DSP noise reduction (Easitalk)

Easitalk has removed much of the background noise and the average signal (shown as a lighter colour) displays a form much more like a voice waveform with highs and lows.
