About this firmware

This firmware is a fork of Egzumer custom firmware, who was a merge of OneOfEleven custom firmware with fagci spectrum analizer plus my few changes.

All is a cloned and customized version of DualTachyon's open firmware found here ... a cool achievement !

Note

About Chirp, as many others firmwares, you need to use a dedicated driver available on this repository.

Warning

THIS FIRMWARE HAS NO REAL BRAIN. PLEASE USE YOUR OWN. Use this firmware at your own risk (entirely). There is absolutely no guarantee that it will work in any way shape or form on your radio(s), it may even brick your radio(s), in which case, you'd need to buy another radio. Anyway, have fun.

Caution

I recommend to backup your eeprom with k5prog before playing with alternative firmwares. It's a good reflex to have.

About the different editions

There are currently 4 different editions of this firmware

  • Bandscope : all features, with bandscope (spectrum analyzer) support, but without broadcast FM support
  • Broadcast : all features, with broadcast FM support, but without bandscope support
  • RescueOps : all features, without bandscope and FM broadcast support, but specifically developed to integrate into a communication system designed for first responders (firefighters, etc.).
  • Voxless : bandscope and broadcast FM support, but without some features. For example, VOX, audio bar, air copy and new bandscope evolutions since v3.0, scan resume mode, etc. are not available. This edition will no longer evolve, due to a lack of free space in flash memory.
