====== VHF / HF X-Gate Project ======

  * my interpretation of the [[https://www.barrettcommunications.com.au/2062-crossgate/|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 <del> [[https://github.com/gm4slv/PythonProjects/tree/master/xgate_m710|here on GitHub]]</del>
  * X-Gate will run in //dumb talkthrough// mode if Raspberry Pi controller is removed
  * Operation of uplink port in full duplex on  VHF and UHF is possible, to enable access regardless of state of talkthrough.
