Lately I have been wondering if anyone has worked toward making several #NooElec NESDRs phase-coherent?

If one of you knows of such an attempt, can you point me to them please?

@AG7GM not familiar with the hardware, but they appear to use the same chip as any RTL-SDR DVB-T dongle and there's plenty of those being used coherently.

Essentially, get a clock, 10 MHz if I recall, distribute it to each unit. Job done.
