When I first turn on the radio it works fine but after several hours it stops syncing, My Flex5000 stays locked that is using the same source and have noticed NO issues with the 10MHz source failing.
Anyone else having this same issue?
Sounds like the problem is the 6500 is saying it lost the ext sig, for whatever reason.
Spec is 1.0V P-P min, 3.3V P-P maximum. (4dBm min - +15dBm max)
One should check when connected.
Hope you can track this down.
All I was asking is if others where having the same issues when trying to use the external GPS source for extended radio power up.
If people don't have a way to test this then there is no need to respond to my query.

2: turn the radio on and go to 10.0000MHz
3:ZOOM in so the pass band fills as far as you can zoom using the magnifying glass icon in the bottom left of the SmartSDR display.
4: the center carrier on AM should be exactly ZERO beet with 10.0000 MHz on the radio if not then it isn't locked to your 10MHz Source or your source is off frequency, you should see your own 10MHz source if wwv signal is lower then your 10 MHz source.
5: there should also be 2 smaller peaks on either side of the center 10MHz WWV carrier so you know which one is WWV.
6: stop SmartSDR BUT leave the radio powered on overnight and check it the next morning to see if it stays put.
Mine does NOT stay locked but reverts back to the internal clock which is off a little bit.
I'll try to enclose a picture of how it looks when it's locked on.
WWV on 15MHz should also be exact center when it is locked on.
That's a reasonable test. It looks like I'm on freq. (I'll try to insert the image) Now I'm wondering why I can't zoom in as much as you. Your first freq hack with a label is at +/- 100 Hz, but my first labeled hack is at +/- 400 Hz. And I have the slice zoomed in all the way.
I think it would be reasonable to suggest to Tim that they consider adding a discrete indication to SSDR. Perhaps in the menu bar or somewhere in the Radio Setup dialog box. Any thoughts on that? It could give you an easier indication of where things are going wrong for you.
Don't forget to check yours again after the radio has been powered on for a long time and please report back here if you would.
Could be just your monitor resolution why it won't zoom in as far as mine does, my radio is a 6700.
This is after leaving the radio on for about 12 hours.
if no one elses is doing this then maybe my comercial 10MHz source is reseting in the night.
When you have the internal or external 10mhz source, what happens when you hit the START button under the RX Freq Offset menu ?
Does the radio compare the frequency against the 10mhz source ?
Or is this menu disabled because of the internal timebase ?
With the internal gpsdo, SSDR detects it's presence when it starts, and disciplines the T/OXCO from then on. The only way to check the frequency calibration on the RX Freq Offset menu is to disable the gpsdo first. Then the options to do that appear.

I run a GPSDO 10Mhz. reference oscillator with my other rigs here. I had to order a BNC to RCA pin adapter to work with my new Flex 6500. I hope to have it running in a couple days. I will get back to you with my results. Hopefully it will stay locked to the GPSDO standard 24/7. My other radios certainly do.
There should be some sort if indicator to let me that it is staying locked. Having to zoom in on WWV is not a good solution.
Connected my 10Mhz GPSDO Reference to my new Flex 6500. I am feeding a 2.2V P-P 10Mhz. sine wave with no DC offset. Plus 1.1V to minus 1.1V. It locked up fine when I re-booted the 6500 and it is right on WWV frequency.
I run my equipment 24/7 here so will check it tomorrow to see if it is still locked up and will let you know.
I been running with my GPSDO for about 24 hours here and it is staying locked up. I zoomed in on WWV and it is staying right on the money. I would suggest checking the signal from your GPSDO on a scope. I have a clean 10Mhz. sine wave 2.2V P-P on my Tektronix 465.
The Flex manual states 1 to 3.3 Volts peak to peak.
Good luck, I hope you can figure it out.
