Worck by an external 10 MHz oscillator

[van341]

I want to receive 4 channels synchronously from 2x LibreSDR. To do this, I connect the corresponding generator via the MMCX connector. The corresponding LED is not lights up on the device and there is no synchronous reception. The firmware supports the ability to operate from an external generator, and what changes (settings) need to be installed to make it work?

any progress on this? from what I can tell you just need to make sure your reference signal is 7db at least?
