- | * The signal is **delayed by 30ms,** so it is **not possible to keying CW from the local paddle.** Na osciloskopu vidime zlute originalni CW tecky o rychlosti 28 WPM a na modrem prubehu audio zpozdene pres Bluetooth modul VS-3. \\ {{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 blue waveform shows the audio from the Icom VS-3 Bluetooth module, which significantly emphasizes high notes and adds noise. \\ {{https:// | + | * The signal is **delayed by 30ms,** so it is **not possible to keying CW from the local paddle.** On the oscilloscope we see the yellow original CW dots at a speed of 28 WPM and on the blue waveform the audio is delayed via the VS-3 Bluetooth module. \\ {{https:// |

+ | ===== SSB operation | ||
+ | * Signal delay in SSB mode does not matter. | ||
+ | * It is a one-second chirp with a 6kHz lift. | ||

+ | * The **PTT** button is **very practical and works flawlessly.** | ||

+ | ===== Conclusion ===== | ||
+ | * 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. |
