Welcome to the IC-905_Band_Decoder_on_ESP32-S3 wiki!

This project works with the IC-905, IC-705 and IC-9700. Detection is automatic and the correct radio bands definitions are loaded when the radio is detected on USB connection. The IC-9700 only uses the first 3 of the 6 predefined IC-905 bands. There are 2 groups of 6 IO pins, BAND and PTT. You can program them to output any pattern you want for any band.

Check out the Wiki pages listed on the right for build, install, configure, and technical details.

I also have an IC-905 Ethernet Band Decoder that works by tapping intot eh POE ethernet cable beween the controller and the RF Unit. There is also an IC-905 Teensy 4 based remote-control head project that supports transverters and a large touchscreen modeled after my Teensy SDR.
