Radio will not transmit with Nextion screen.

Post by WB4SJN »

I have a pi3B+ that has been working well. I added the nextion screen and it is operating as it should. It has all the information it is supposed to have. When I receive a signal it shows everything just as is supposed to.When I press the PTT on my radio nothing happens. A friend has 9 hotspots all with Nextion screen and all of them work perfectly. He is the one that assisted me setting up mine. Before I loaded the screen the pi was working perfectly. We have not been able to find the problem so I am hoping the forum can guide me. Many thanks for any help. 73.

The TX/RX frequencies are 438.800. The screen is plugged into the pi3B+ USB port.

Thank you for your concern. I found the problem. We had set the TX/RX offsets at -500. I checked a file from a long time ago and found that the offsets were 500 not -500. When I reset the offsets back to 500 the radio responded but with a BER over 5. I dropped the offset to 400 and the BER is now less than 1. 73.
