[time-nuts] Low cost SDR suitable for phase noise measurement?

[Brooke Clarke]

Hi Bob:

The SDR-IQ has a lower frequency limit of 500 Hz.

There is a mod that replaces the on board 66 MHz oscillator with one locked to 10 MHz.

> A number of posts have appeared about Zynq SDRs on the "Shera revisited" thread.  So, I'd like to ask the more general question: Are there any low cost SDRs that are suitable for measuring phase noise when coupled with a DMTD?  I believe what I'm looking for is something with enough bits to work in the audio range down to DC.  Yes, I could use a modified sound card, but I'm really looking for something not sound card related.  My thought was to use a DMTD with a heterodyne frequency of maybe 5KHz.
