• my interpretation of the Barrett Radio 2062 Crossgate
• HF port has syllabic squelch for better detection of SSB speech signals
• VHF port has DTMF decoder for control commands
• Raspberry Pi running a Python application handles control of HF radio via NMEA and of talkthrough functions etc. via GPIO
• DTMF commands for control of Icom IC-M710 : Frequency, Mode (USB/LSB/AM), Power (20W/50W/100W), ATU Tune cycle
• DTMF control of talk-through (HF transceive) or monitor (HF Receive) functions
• Morse Code (CW) revertives over VHF port to read back parameters such as HF radio frequency, mode, power etc.
• Built in Webserver for status display http://gm4slv.plus.com:42109/
• Python code is here on GitHub
• X-Gate will run in dumb talkthrough mode if Raspberry Pi controller is removed

A short You Tube Video of the X-Gate in action.
