Link Density Mode

As of firmware version 3.0, the Digital 6000 series supports Link Density mode (LD mode).

LD mode doubles the number of usable carrier frequencies in the available spectrum, as the minimum distance for the equidistant frequency grid is reduced from 400 to 200 kHz.

This is achieved by reducing the transmission power and modulation bandwidth of the transmitter. This means that a much smaller frequency spacing between neighboring frequencies can be selected, and therefore more frequencies can be used in the same available spectrum without intermodulation.

For information about setting the transmission mode, see System -> Transmission Mode menu item.
For information about the equidistant frequency grid, see Equidistant frequency grid.
Use of Link Density mode is recommended if the following criteria are met:
  • The required number of channels cannot be achieved using LR mode, as there may be only a small spectrum available.
  • The distance from the transmitter to the antennas is not too long but also not so short that blocking effects could occur.
  • The audio codec for LD mode is suitable for the required application.
