My left arrow button on the openmd9600 does channel skip. The right button does it on my Opengd77. Are these buttons backwards?
AFIK there is no 'left arrow' button.

The first post of "Installation information" shows “B” key = Left Arrow, “C” key = Right Arrow. B key happens to work channel skip or nuisance delete, right arrow works it on the GD-77. BTW great job on the build.

I think the keys have been changed since that post, now B = Right, C = Left
I've updated the original post.

AFIK. No driver is required on any Windows version for the official firmware, because the official firmware shows as standard USB HID device.
so if you have the driver installed for the openmd-6900, do you need to change it to remove firmware to go back to factory?

Where can i find the instructions to reverse the install of the open md-9600 back to factory. I have tried a few times, but I am missing something.

Assuming you backed up the Flash, you can restore it, and put back the origainal codeplug, and radio password etc etc

Then use the official loader to flash the official firmware. Note. If you don't load the exact official firmware for your radio hardware model, the Tx and Rx won't work, but the display and keypad etc will work.


If you didn't backup and then restore the flash, when you have loaded the official firmware you will probably get a message about a password.

To fix this you need to change a line in the official CPS setting.ini file from

password=0

to

password=password

Then reload your original codeplug

Hello everyone, I noticed that when the device is squelch, it cuts my words on simplexes and repeaters. Now I have put new firmware so we will see how it will behave.

Sounds like over deviation clipping, which happens more if you have Rx CTCSS enabled.
Personally I don't use Rx CTCSS.

After flashing the new firmware, I had to reinsert the codeplac because the station went crazy. Now everything is fine again. MD9600_firmware_V2HW

When i try to use the default loader for the default bin file it crashes about 5 seconds after starting, and the download never starts.
