  Jerry, it sounds like it is helpdesk ticket time. Submit at http://helpdesk.flexradio.com
  
  You probably won't get an answer until Monday.

  If it is still under warranty, you probably shouldn't be opening it up.
  This may sound like an obvious question but do you have the antenna in a south facing window with a unobstructed or near unobstructed view of the southern sky?
  beyond that, yep, open a ticket.

  I had this problem when I received my 6700 back after an update. Getna helpdesk ticket and get permission to open the case and reseat the GPS board. Reseating the board solved my problem.

  Jerry - there should be +5 VDC on the center pin of the SMA GPS antenna connector.  Since there isn't, this appears to be a hardware issue.  I have converted this topic to a support HelpDesk ticket (http://helpdesk.flexradio.com) for expedited issue resolution.  A tech support engineer will be in touch on Monday when the office opens.

  I had the same problem on my 6700 and found that the GPS module was not reinstalled properly when it was returned from Flex after the Factory PEN upgrade. The GPS Module mounting position seems to be very sensitive on my radio, it required several tries to get it seated right. It would work then not work but after 4 tries it finally continued to run. 73 Al N4AB

  This appears to be a hardware issue that is being resolved via the HelpDesk.

  I have a quality GPS antenna made by Trimble Navigation. If I replace the original GPS antenna provided with with the GPSDO, can I expect any improvement with frequency stability or accuracy? Is it worth doing?

  If the GPSDO is a locked state, then the frequency accuracy and stability are within spec for the GPSDO.  If one antenna sees more satellites and can lock on more than the other, it will slightly improve short-term accuracy and provide a faster lock.  Once the GPSDO is locked and the GPS has had sufficient time to discipline the XO to 10 MHz, as noted the stability will be within spec ( 5 x 10 (-12) over 24 hours).
