Does anyone own the GPSDO unit?

Have two that I use. The one on my 6700 today is a Jackson-Labs Fury, providing an external 10 MHz reference. My other external reference is a tenMHz LPRO-GPSDO reference oscillator with rubidium oscillator.

I suspect that by adding the internal GPSDO, Flex's firmware will eventually allow for accurate time stamping of the VITA-49 streaming IQ. That would be a really great feature.

My view of the FLEX GPSDO is that it is a high quality frequency reference.  It is manufactured for FLEX by Jackson Labs.  Jackson Labs is known as one of the highest quality manufacturers of GPSDO devices.

Today a stable signal is essential for certain weak signal modes and for driving transverters for use on VHF/UHF/microwave bands.  In addition to providing a frequency reference for use inside my FLEX-6700, the FLEX GPSDO also provides a 10 MHz reference signal output for use with other devices.

The 10 MHz reference out from my GPSDO feeds a Stanford Research Systems FS-730/1 10 MHz distribution (and buffer) amplifier.  The FS-730/1 has 7 outputs which replicate the reference signal, buffer the signal, and provide channel to channel isolation.  This prevents noise from any connected device from being re-transmitted to other connected devices.

I use the outputs from the FS-730/1 to feed reference signals to other transceivers (TS-990S, K3s, & IC-7800) and to test equipment (spectrum analyzer, oscilloscope, and arbitrary function/waveform generator.)

In the future the FLEX GPSDO may be important for use with new modes or software.  For now, it provides me with a high quality 10 MHz reference source for use with 6 other pieces of equipment.

I like my GPSDO. It's keeping things calibrated for now. In the future it has been suggested that it might be used to provide additional features. Such as serving as a timing source for your PC, And possibly allowing us to sync our receivers to other remote 6XXX series receivers, maybe for diversity reception, or Beam Steering.
