Hi all!
Is anyone see such behaviour, when trying to run two modulators in SFN mode?

I see in oscilloscope that my 10MHz sources are equal, but having small jitter, maybe this jitter produces such fluctuations when 10MHz multiplied by the PLL. Not sure.

This is spectrum of two transmitters mixed together and received by rtl-sdr.

When this happens, the constellation map amplitude decreases to values even smaller comparing when transmitting from just a single transmitter.
