VHF / HF X-Gate Project
- 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
- Operation of uplink port in full duplex on VHF and UHF is possible, to enable access regardless of state of talkthrough.
