Can the 8400 / 8600 GPSDO upgrade be disabled so an external frequency source can be used?

Can the 8400 / 8600 GPSDO upgrade be disabled so an external frequency source can be used?

All of the frequency and timing signals for my shack now come from a Symmetricom Time and Frequency server that's GPS locked and distributed to my 6600 (which I want to replace with the 8600), Q5 transverters, K4 and other test equipment.

    Hi Roger, can you select it using the 10 MHz Reference Source drop-down box?

    I don't have the GPSDO option, so I can't try it here. With just the built-in GNSS, I can easily switch among the different reference options.

    Hi Len,

    I was looking at the 8600 that Bill, NO4ON has for sale on the Flex Community and trying to figure out if I can use my SYmmetricom Time & Frequency server with it instead of the GPSDO option that it has in it, so I don't have a radio to try it on.

    Hi Roger, have Bill send you a screenshot similar to mine. That will tell you for sure.

Rich Text Editor. To edit a paragraph's style, hit tab to get to the paragraph menu. From there you will be able to pick one style. Nothing defaults to paragraph. An inline formatting menu will show up when you select text. Hit tab to get into that menu. Some elements, such as rich link embeds, images, loading indicators, and error messages may get inserted into the editor. You may navigate to these using the arrow keys inside of the editor and delete them with the delete or backspace key.
