Starting

There are three ways to display the transmit options:

  1. From the Transmit pane of the ribbon bar,
  2. From the ribbon bar button (top left),
  3. Click the [•••] button in the TX panel of the Transmit DSP panel.

The first page is itself a link to the hardware-specific options. The rest of this page describes the common transmit options.

 
Equaliser

The equaliser supports three designs [wikipedia]:

  1. Peaking equaliser,
  2. Low-shelf,
  3. High-shelf.

The peaking equaliser send the input signal to a bank of filters. Each filter passes the portion of the signal present in its own frequency range or band.

The low-shelf and high-shelf filters are used to reduce or increase signals above or below a set frequency.

It would seem that high boost is needed on sideband.

 

Master Gain Settings

For each band you define the maximum gain, processing and drive levels. In this window you adjust the levels with the sliders and, if required add up to 20dB of extra gain.

 

Modes

Some modes have their own options. At present only AM is supported here:

 

Bandpass

Here you define a series of filters which select in the Input Panel of the Transmit DSP. The selected filter determines the transmitted bandwidth.

Click Definitions to display the Filter Definitions window.

Click Add and follow the instructions on the definition window.

 

Tones

There is a tone generator built into the software, this is used for testing the transmitter. Typically you use two tones, 700 and 1900Hz.
