RD-5R power switch

Another difference between RD-5R and GD-77 is the power switch. In GD-77 the switch is "soft", so before really switching off the GD-77 software has a chance to save the current channel. However, in RD-5R the power switch cuts the power off immediately, so the firmware does not run any more. So on R...

RD-5R

Be aware there are some limitations to the firmware on the RD5R. Hotspot does not work due to hardware limations and the 100Mhz band FM Rx does not work, because we have been unable to find a datasheet for that chip. We know the part number of the 100MHz FM radio chip, but all available data sheets...

Re: Sigh... Windows 11 and Apple M1 Mac

So you can't select the COM port manually in CPS? Another way is to use the CPS only for building your codeplug, but use Python program GD77transfer in Linux for uploading the codeplug file to your radio. You can download the latest version here: https://www.opengd77.com/viewtopic.php?f=13&t=1864&p=...

* Improved CPS data transfer speeds
How is this implemented?

I'm just wondering whether I could do the same thing for my Python program GD77transfer.py...

Is this change backwards compatible?

Re: Hello from DJ1LA

Hi! In order to upload firmware (a .sgl file) to the radio, you must boot into bootloader mode (SK1+SK2+power on). Then the radio will appear as a HID device on your PC. The gd-77_firmware_loader.py script works fine in Linux, after you update the udev rules. For example, see the last two code secti...

Re: Baefeng RD-5R

For the diagram of keys see the User Guide, section The control keys and buttons

Flashlight is Fn+5 (called LED lighting in the diagram).

AFAIK, listening FM broadcast is not supported. See http://www.opengd77.com/viewtopic.php?f=7&t=891.

Re: GD77 cable detected as USB input device.

Actually, the cable is just wires, all of the USB electronics is in the radio. So I guess you mean that your radio is detected as a USB input device. That is the correct behaviour in firmware upgrade mode, the radio appears as a HID (human interface device). But if you power on the radio normally an...

Flash_Lower_64k.bin does not contain your calibration data. See details here: https://www.opengd77.com/viewtopic.php?f=13&t=999

Re: Public Beta (2021 09 14)

german.h is source code which is used when compiling firmware (the .bin file).
wordlist CSV files are used in building the voice prompt files (.vpr).
These .h and .csv files are only needed by developers. End users can ignore them, you do not have to download them.

Re: Python program for updating satellite keps

Thanks for finding the bug! I have attached a corrected version of the program (only GD77transfer.py is changed).
