1 Khz tone
Posted: 03 Nov 2022, 14:03
Hi guys.
I hope someone can help me.
I bought my (tr)uSDX a year ago as a group by kit. I posted a video of my problem on FB: https://www.facebook.com/1050543270/vid ... 925756401/
I have a problem on USB or LSB transmission. When I transmit on USB, there is a tone that is 1kHz above the base frequency. At LSB it is 1 kHz down. In the video, the tone can be seen and heard on the Web SDR receiver at 14.251 MHz (1Khz tone).
I don't know a lot about electronics so, I don't know where to look for the error. A colleague who helped me with the assembly, visually inspected the boards and did not find any errors.
I reloaded the firmware and checked if the boards are touching anywhere. Unfortunately, without success.
I work with an internal microphone. For the test, I inserted an "empty" 3.5 mm connector into the microphone jack (without wires) to disconnect the internal microphone. The result is the same...
Has anyone had the same problem.
Thanks,
