      SDRPLAY DX ordered and on the way. Is there a PDF instructions sheet for using the external clock port?


        The level should not substantially exceed 3v p-p. Larger levels should not cause damage, but they may result in degraded phase noise.

        This application note for connecting to a Leo Bodnar Precision GPS Disciplined Oscillator shows the setup: http://www.sdr-kits.net/documents/SDRPlay%20RSP%20External%20Clock%20in%20Cable%20use.pdf The RSPdx is more plug and play than the earlier RSP2 and RSP2pro versions so less care is needed in adjusting the exact levels in the case of problems.


          Alternate procedure for the latest Leo Bodnar GPSDO (FW=1.17 SW=9.12). Output 1 must be set to 10 MHz and Output 2 to 24 MHz, enable and use Output 2. The original procedure produced an unstable 24 MHz reference with the latest HW and FW.
