Good so the RT is scrolling now. But where are the preset stations? I use them a lot and in this firmware i don't find them. Battery voltage is gone too.

Everything is written in the comments,even the division of SW into meter bands is lost.
With that new firmware version the signal strength reading has no delay, everything else is still not finally resolved as far as I can see.

Re: Module radio tuner IC, NXP TEF6686

Hello!
My name is Miquel and I write from Spain.
I really like the TEF6686 receiver designed by Mr. Marsel.
I have successfully built the TEF6686 receiver and it is very good for DXing.
I have built another one for another friend but with the Arduino Nano Every
I forgot that the Arduino Nano has the ATmega 328p chip and the Arduino Nano Every has the ATmega 4809 chip.
Is TEF6686-arduino-F8605.ino totally incompatible with Arduino Nano Every?
Is it easy to fix the problem?

Below I copy the error message.

Thank you very much for your help!

Yes, many of the good features that have been implemented separatelly by the Chinese team have been lost. The battery voltage is now hidden and shows the wrong value and percent. Also the bands are lost and not least the possibility to store some favorite frequesncies. I have requeted the seller from Aliexpress to provide me the original version they sent the radio with. Version 1.18

I have restored my radio to it's initial firmware and now is working fine.

In case someone needs that version I can provide it but please be aware that the files are in Chinese so not so easy to use. :)

I fortunately did a backup of the firmware that the radio came with, before making an upgrade. Here is the bootscreen info if someone needs the fw file, I can send.

Everybody has a radio. To listen to a radio is normal. To listen to a radio, that is far away from you is a DARE!

Hello Miquel
If you have installed the libraries for nano every - pun in sketch comment on the line
//TWCR = 0; // Release SDA and SCL lines used by hardware I2C
possible when closing TEF-GTK/ XDR-GTK not to stop the tuner only after disconnecting from usb !

Thank you very much Marcel!
Yes. I have installed the libraries for Arduino Nano Every.
It has worked perfectly.
I don't know if I've done it right.
The only thing I have changed

Before

TWCR = 0; // Release SDA and SCL lines used by hardware I2C

Now

//TWCR = 0; // Release SDA and SCL lines used by hardware I2C



Just writing "//"

Now I use your radio in muy car. I love your TEF6686 radio. It's the best DX radio I've ever had. And I had a lot of DX radio.
Thank you for your help!
¡Muchas gracias!
Sorry for my bad English!
