BITX40v3 is alive!

It took me about an hour to build the BITX40, this is a really fun little project. After the first installation I updated the Raduino from Version 1.01 to version 1.10

https://github.com/amunters/bitx40

This adds tons of new features, all the features can be found here;

https://github.com/amunters/bitx40/blob/master/README.md

I am still running the standard hardware, I will add the following hardware extension soon;

  • Function button
  • CW Carrier
  • PTT Sense
  • TX RX Line wiring
  • Sidetone wiring

This is a cool project, I like all the experimenting and extending that is possible.

Thanks and 73,
Daniel de DL6FZ

This is a great and very helpfull website: TYT MD380 Tools

Please have a look at the following Website. As I have been flashing the Retevis RT3 and MD380 for a long time manually now, I still thought this website to be very helpfull.

TYT MD380 Tools

It has a very nice overview of all the features the MD380 hacked Firmware offers. Also the DEVONLY features are very well described. Great job guys!
