Powered up bitx40 and immediately have a tone in the speaker, and no info on display.?
I initially miswired the Raduino. I used the 8 pin connector and matched the colors, didn’t use the 16 pin connector.

When it powered up the display showed briefly. I powered it off. I rewired it and have the tone.?

With the Raduino otherwise disconnected, can you plug its USB port into a USB line from your computer or a cell charger? That will power it up on 5v and you can see if it is displaying and acting normally to see if it has any issues from being misswired.

No display, I guess I toasted it.
i will try one from one of my ubitx?
