Re: Just 2 wishes for VFO Mode
I agree that using P1+ * is awkward when driving. However you can always use the 'Sticky SK2' key which can be done one handed with just the microphone. Long press D until it double beeps. This simulates SK2 being pressed and held down. Then press * to switch between DMR and FM. After a short time t...

Re: TYT MD-750 ???
This has been asked before.
Unfortunately the answer is no.
This is because the MD750 uses the HRC7000 chip for which there is very little documentation and no publicly available toolchain.

Re: MD9600 manual backlight toggle
You are correct, at the moment there is no key assigned to the manual backlight. So it can't be used.

Re: Hello & Thanks
Hello Gav, Welcome. The firmware was originally written for the buttons and keys available on a handheld, so when converting to the MD9600 mobile a few changes were needed. Everything should work but the key sequences used may be slightly different. The user guide doesn't yet accurately reflect the ...

Re: "B" dtmf tone unavailable?
We had to remap some features due to missing keys.

SK1 + Up arrow = B
Down arrow = C
SK1 + Down arrow = D

Re: Com Port not available
If you are trying to load new firmware you must put the radio into bootloader mode.
Hold down the top two side keys when turning on the radio.

Re: Baofeng Dm-5r
Open GD77 does not transmit on both timeslots at the same time. It does however only support the DMR standard Direct mode for simplex. Direct mode transmits with a 50% 'Single Slot' duty cycle but the transmission does not contain any information regarding timeslot. There is no master timing referen...

Re: DTMF dial Tx CTCSS problem
As Roger says, at the moment we cannot send CTCSS and DTMF at the same time on the STM32 based radios. This is a limitation of the HRC6000 Chip which we are using to generate both systems, it can only do one at at time. When DTMF is sent the CTCSS is paused for the duration of the digits. We maybe a...
