Hi Bob: The SDR-IQ has a lower frequency limit of 500 Hz. http://www.prc68.com/I/Bats.shtml#SDRIQ
There is a mod that replaces the on board 66 MHz oscillator with one locked to 10 MHz. -- Have Fun, Brooke Clarke, N6GCE http://www.PRC68.com http://www.end2partygovernment.com/2012Issues.html The lesser of evils is still evil. -------- Original Message --------
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.
