That message indicates an issue with the driver and cable, not the software.

Subject: [chirp_users] Help with new radio

Hi all,

I have an issue with my new UV-5X. (shocking)

The firmware version is P51UV01 and CHIRP will not communicate with the radio.

My COM port is 3, the radio is a baofeng and the model is UV-5X

The CHIRP message is "Rado did not respond"

Tried a bunch of baofeng models and got the same response.

Downloaded the baofeng software and it reads the radio fine.

I can make changes from the keypad of the radio and they show up in the baofeng software when I redownload from the radio.

This also works when I use the software to make changes and write the changes to the radio.

It appears CHIRP doesn't work with this firmware update.

Please correct me if I am wrong, as I am often wrong.

This setup is working for me but I prefer CHIRP.
