<-[[.:]] ====== 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 * Operation of uplink port in full duplex on VHF and UHF is possible, to enable access regardless of state of talkthrough. ===== DTMF Commands ===== ^Function^Command^Comment^ |Log on | 0# | | |Log off | *99*# | | |Set Frequency | *1fffff# | ffff.f kHz | |Set Channel | *1xxxx# | mem chan xxxx | |Set Mode USB | *21# | | |Set Mode LSB | *22# | | |Set Mode AM | *23# | | |Set TX Power Low | *41# | 15W | |Set TX Power Medium | *42# | 50W | |Set TX Power High | *43# | 100W | |QSY Down 0.5kHz | *5# | | |QSY Up 0.5kHz | *6# | | |Monitor HF | *7# | 5 seconds | |Monitor HF | *7xx# | xx seconds | |Monitor HF | *7*1# |(Duplex Mode) Continuous Monitor ON | |Monitor HF | *7*0# |(Duplex Mode) Continuous Monitor OFF | |ATU Tune | *8# | | |Status | *9# | | |S-Meter | *91# | | |Full Status | *93# | | |Talkthrough ON | *01# | | |Talkthrough OFF | *00# | | ===== Further Information ===== | Barrett 2062 Brochure | {{ :public:radio:dormant:2062_cross_gate_brochure_english.pdf |}} | | Barrett 2062 Manual | {{ :public:radio:dormant:barrett-2062-hf-vhf-uhf-crossgate-operation-manual-12.pdf |}} | * new developments....
