K7MDL

KEITHSDR. Teensy4.X with PJRC audio card Arduino based SDR Radio project.

RF-Power-Meter-V1. RF wattmeter and Band Decoder on Arduino or PSoC5 modules with Python desktop monitoring and control app. Remote operation via USB Serial or Ethernet (new).

IC-705-BLE-Serial-Example. Band decoder for an Icom IC-705 radio using Bluetooth Low Energy (BLE) and BT Classic Serial Port Profile for CI-V control and USB Host for a wider range of CI-V radios. Also a related 3-Band transverter box to add 222, 902/3 and 1296 bands to the 705 in a highly integrated manner.

K3NG_Keyer_ESP32_BT_Keyboard. Fork of 2022 vintage K3NG Keyer modified to run on ESP32-WROOM-32 and Pico2W, updated with relevent changes up to 2025. Adds BT Keyboard capability (BLE and BT classic), Classic I2C LCD text display and a color TFT Touch displays.

IC-905_Band_Decoder_on_ESP32-S3. The Icom IC-905, IC-705, and IC-9700 only have a single PTT (SEND) output. Band information must be extracted from USB or LAN. This is a Band Decoder and PTT Breakout for 6 bands. Uses an ESP32-S3 in USB host mode, talks to the radio with CI-V Serial protocol.

ICOM_IC-905_CIV. A USB Serial band decoder and PTT breakout for the Icom IC-905 and IC-705, maybe other models. Can configure as a simple headless low power compact box, or add a touch display and optional encoders and switches for a remote control that supports transverter band display, control and band select.

Teensy4_USB_Host_RS-HFIQ_Library. Teensy 4.0 or 4.1 USB Host Port serial control for the 5W RS-HFIQ SDR transceiver

OTRSP_BAND_DECODER. Arduino Band Decoder (only) Example for OTRSP Protocol Serial Messages

CI-V_Serial_Band_Decoder. Serial Band Decoder for CI-V radios (IC-705, IC-905, IC-9700) written in Python. Mostly intended for remote location over ethernet. Uses a virtual serial port in wfView co-located on a Pi CPU to communicate with the radio.

CIV-USB-Band-Decoder. Teensy 4 based USB Band Decoder for modern Icom CIV radios. Passes through PC serial data, monitors for band data and PTT. 2nd serial passes GPS data to PC. Tested on IC-905, IC-705.

IC905_Ethernet_Decoder. IC-905 Ethernet Band Decoder on Raspberry Pi

HL2_IO_BOARD_BCD. BCD and PTT outputs for the HL2 IO board designed by N2ADR. VHF band focused, modify to suit your needs.
