| * Signal delay in SSB mode does not matter. **The audio accentuates the higher notes, but it's not annoying.** On the image from the oscilloscope we see a yellow signal representing the original audio from the headphone output, which slightly suppresses the higher tones. The blue waveform shows the audio from the Icom VS-3 Bluetooth module, which significantly emphasizes high notes and adds noise. \\ {{https:// | * Signal delay in SSB mode does not matter. **The audio accentuates the higher notes, but it's not annoying.** On the image from the oscilloscope we see a yellow signal representing the original audio from the headphone output, which slightly suppresses the higher tones.

| + | * The latency of the audio signal delay is a property, it is not a device error. | ||
| + | * Suppression of high frequencies would probably improve the useful properties of the device, which are good except for the CW mode. | ||
