I have also opened the cover and there is no resistor on the rx-line. Unfortunately I do not have this tiny resistor, but I will get one.
I think you can shorted this resistor, I will work. ;)

Re: GPS sensor

The GPS is worked with U-center via FTDI adptor. Can you also change the settings with u-center? I have a ublox7 too which does not work with oXs. It seems that this gps only send the coordinates but changing the settings (e.g. baudrate) is not possible. That's why it does not work with oXs. I can ...

Re: ArduVoice-9x Voice Module with Arduino for the 9x Radio

Dear Joao,
I have tied two way:
1. Flash bootloader by ISP first and flash firmware by serial.
2. Flash combined (firmware and bootloader) by ISP.
Both have same result.
Trims and the backlight work after I press press the reset button.
Thank you so much for your help.
