Use the wheels to adjust the frequency shift in Hz from the center frequency of transmission. Left click on a digit sets the cursor position at this digit. Right click on a digit sets all digits on the right to zero. This effectively floors value at the digit position. Wheels are moved with the mousewheel while pointing at the wheel or by selecting the wheel with the left mouse click and using the keyboard arrows. Pressing shift simultaneously moves digit by 5 and pressing control moves it by 2.
This is the bandwidth in kHz of the channel signal filtered after modulation. It can be set in discrete values: 3, 4, 5, 6.25, 8.33, 10, 12.5, 15, 20, 25 and 40 kHz
Sets the CW speed in Words Per Minute (WPM). This is based on the word "PARIS" sent 5 times. For 5 WPM the dot length is 240 ms. In other terms the dot length is calculated as 1.2 / WPM seconds. The dot length is used as the base to compute other timings:
- Element (dot or dash) silence separator: 1 dot length
⚠ WARNING: what follows is not really useful if you do not use a proper Morse keyer with direct audio feedback. There is a significant audio delay either with the direct monitoring or by monitoring the transmitted signal so keying with this audio as feedback is not practical
12.7: Activate morse keys keyboard control
This disables text or continuous dots or dashes. Toggle input from keyboard. Occasionnaly the focus may get lost and you will have to deactivate and reactivate it to recover the key bindings.
12.8: Iambic or straight
Choose iambic or straight keying style. When straight is selected the dot or dash key may be used.
12.9: Register dot key
Click on the button and while selected type a character or character and modifier (Shift + key for example) to select which key is used for dots. The key or key sequence appears next (here dot `.`)
12.10: Register dash key
Click on the button and while selected type a character or character and modifier (Shift + key for example) to select which key is used for dashes. The key or key sequence appears next (here dot `.`)
Opens a file dialog to select the audio file to be played. It must be mono 48 kHz F32LE raw format. Using sox a .wav file can be converted with this command: `sox piano.wav -t raw -r 48k -c 1 -b 32 -L -e float piano.raw`
