When you power on your WOLFWAVE, the first screen will show the spectrum of the audio input. The horizontal line above the spectrum indicates the current passband.
The vertical dashed line indicates the centre of the passband, which is also the frequency used by signal detection for CW regeneration, and for the LED. The LED will light up green when a signal is detected near this frequency.
The text in the top right corner shows the current passband parameter being adjusted by the multi-use knob. Turn the knob to adjust the value.
A long press on the multi-use knob switches between centre+width and upper+lower edge adjustment modes. A short tap switches between the parameters in the current adjustment mode – so between centre and width, or between lower and upper edge.
The text below the spectrum indicates the horizontal range of the spectrum. This will automatically change to fit the upper edge of the passband.
The edges of the passband are limited to 100-5000 Hz, and the minimum bandwidth is 50 Hz.
Presets and memory
Your WOLFWAVE has 4 presets to allow you to quickly change to one of the following passbands:
These can be accessed through the menu, by going to "Bandpass filter > Load bandpass" and scrolling to the bottom. These 4 presets are constant and cannot be changed.
The WOLFWAVE also has 10 memory slots which you can use for saving and loading your own passband settings.
To save the current passband, go to "Bandpass filter > Save bandpass" in the menu and select a slot to save it in.
To load a saved passband, go to "Bandpass filter > Load bandpass" and select a slot. The lower and upper edges of the saved passband for each slot are displayed in the menu.
Enable/disable bandpass filtering
Bandpass filtering can be enabled or disabled, by selecting the "Bandpass filtering > Bandpass filtering" menu item.
Disabling bandpass filtering is equivalent to setting it to the maximum range (100-5000 Hz).
