-====== 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 [[https://github.com/gm4slv/PythonProjects/tree/master/xgate_m710|here on GitHub]] 
-  * X-Gate will run in //dumb talkthrough// mode if Raspberry Pi controller is removed
