A new Beta version is now available
downloads/MD9600/Firmware/Latest
Note this page will redirec to the specific release files
Changes in this version are as follows
• Bug fix APRS
• Bug fix boot screen problem
• Bug fix MD9600 1750Hz Tx problem
• Bug fix DMR TA decoding
• Add APRS setting to Channel Details screen
• Added +/- 4.6Mhz repeater frequency shift
• Improve MD9600 and UV380 1750Hz and DTMF tone indication through speaker
• Improve satellite screen.
Maximum number of satellites has been increased from 18 to 25.
More satellites have been added to the CPS, e.g. TEVEL2,3,4,5 etc. Some nonfunctioning satellites have been removed.
Each satellite now has 3 possibly frequencies: Voice, APRS and Beacon, by pressing keys 1,2 or 3
APRS configuration is now defined for each satellite via the satellites.txt file in the CPS
To customise an APRS configuation for a specific satellite e.g. "ISS" create an APRS configuration with the same name as the satellite, and this will be used instead of the APRS configuation for that satellite from satellites.txt in the CPS
APRS Tx is possible on any satellite frequency where the Tx frequency has been enabled, but transmitting on the "Voice" frequency of a satellite e.g. ISS wil not result in your position being sent to APRS.fi and will annoy anyone trying to use the Voice frequency of the satellite.
• Turkish language updates
• Czech language update
• Various other small bug fixes.
Very Important
To use APRS and Satellite mode in this version, you MUST update to the latest CPS.
downloads/CPS/Latest/OpenGD77CPSInstall ... .18.01.exe
In this CPS you will need to re-create any APRS configurations and link them to the appropriate channels, then upload the new codeplug into the radio
In the CPS you MUST upload new satellite Keps
APRS Tx will NOT work unless a channel or VFO has an APRS configuation.
There is no longer a default APRS configration in the firmware.
Remember also. For APRS you must enter your callsign into the CPS. If there is no callsign then the APRS transmission will not be valid.
Thanks as usual to Daniel F1RMB and Colin G4EML for their work on this version
Edit 2023 08 20
There seems to be a problem with the 1750Hz Hz tone transmission having lower deviation levels than in the version before APRS Tx was added
This is under inverstigation now and will be fixed in the next version.
This fix is likely to also improve the ARPS deviation level
