Voice Modes

Microphone

You can use a microphone connected to either the PC or the ANAN hardware. In the DSP panel select the microphone, the entry ✶ Microphone on Radio ✶ selects the microphone connected to the ANAN hardware. The Spectrum window in the DSP panel shows the microphone output after the gain and processing (if selected) are applied.

Adjust the gain/proc and master gain/proc (see common configuration) so that the ALC value peaks somewhere between 100 and 150. The ALC value is shown even when not in transmit.

Use the equaliser to adjust the frequency balance (see common configuration).

Monitor

At present the speakers / headphones on the ANAN hardware are not supported. If you want to hear your own audio select a playback device from the dropdown list. Monitor output is only available when transmitting. (CW sidetone is only heard through speakers connected to the ANAN radio.)

Mode

Select the desired mode - at present only LSB and USB are available, but you can always send CW!

Drive Level

With the ALC peaking between 100 and 150 switch to transmit (use either VOX or press the TX button). Adjust the drive slider to set the output level. An alternate method is to use the tone generator (see common configuration) by selecting Tone - you are then transmitting a steady tone (or tones).

Signal Quality

The Pure Signal approach is supported by SDR Console, use this to ensure your signal is as clean as possible.

Equaliser

The equaliser supports three methods to adjust the frequency balance:

  1. Graphical equaliser where the input signal is passed through a bank of filters, one filter per octave. Each filter is indepent with its own adjustment.
  2. Low shelf filter which adjusts the signal level below a specific frequency, and
  3. High shelf filter which adjusts the signal level above a specific frequency.

Changes are applied immediately.

 

 

Microphone

You do not need an expensive super-duper professional quality microphone. For development the TONOR Professional Singing Karaoke Vocal Dynamic Microphone is resulting in reports of very good quality audio. This typically costs less than $25 and comes with a 9.8ft (3m) cable!

Recording

To make a recording of the audio as sent to the transmitter click the recording button in the Input pane of the DSP panel. The recording is saved as a Windows Media Audio (WMA) file which you play with any Windows media application.
