FLEX-6700 SSDR V3 - Radio lockup at startup with 8 panadapters active?

Keith - AE5XN

Can someone else with a FLEX-6700 try this scenario with SSDR V3 for Windows?
Not sure if it's my radio or the new V3 causing this:

1) Open SSDR for Windows V3 and then make 8 panadapters active.  Does not matter which bands or modes they are active on.  You can even start with a factory default fresh profile.
2) Close SSDR V3 for Windows after making 8 pandadapters active.
3) Try to then launch SSDR V3 for Windows again, and see if your FLEX-6700 disconnects, causing the radio to lock up, then require a long power button press to shutdown the radio.  
In order to get SSDR V3 to connect to the FLEX-6700 again, I have to reset the radio to factory defaults.  Trying to run without resetting to defaults keeps 8 panadapters, and causes it to disconnect/crash again at startup of SSDR V3.

I can go back to V2.4.9 and not have this issue.
I can have up to 7 panadapters active and not have this issue.

This even happens with just factory default profiles, as long as 8 pandapters were active before SSDR V3 was shut down.

I have a Ryzen 2700X PC with Windows 10 Pro 1809 and one with a i9-7980XE running Windows 10 Pro 19H1 release preview.  Both behave exactly the same, even with a clean install of both Windows and SSDR V3.  Going back to SSDR V2.4.9 has no issues with 8 panadapters whatsoever.  Radio is connected to both of the PCs via 1Gig ethernet and GS108 switch.

Curious to know if this is isolated to my radio/setup only. 
Note that my radio is a very early Signature Series 6700, S/N 30, but getting no errors when this happens on the front panel.

Along those lines, as you open more pans the amount of data traffic increases. It may be that your network is stressed a bit because of this.

Thanks! At least I know it’s isolated to my environment, and not V3 specifically. Keith - AE5XN

Bill, Thanks, yes, it’s either network, radio, or even voltage drop related. My radio now has some age on it, since it was one of the initial build units for the 6700. My duty cycle has been 99% listening, 1% transmitting, but could be that there is some oxide built up on the blade fuses inside or the PowerPoles. At least I have some ideas of what to look at.

Hello Keith-
I have a 6700 and run 8 pans all the time without issue. I would recommend opening a help desk ticket. G/L

Thanks everyone for all the suggestions. I’ve tried isolating the radio to a direct Ethernet cable connection, using a different cable and different Ethernet adapter than the ones used on the GS108 switch connection, and the result is the same. Also tried bumping up the power supply voltage to 14.5V, with the same results. It just won’t take opening with 8 panadapters with V3, yet works with V2.4.9. It also has no issue transmitting and getting a full 100W out into a dummy load, so that also tends to rule out a voltage drop issue. It will run with 8 panadapters on V3 if you start with 7 or less active, then make the 8th active, but it crashes the radio when you start up with 8. Looks like a Help Desk ticket may be in order..

I would go ahead and start a ticket.

Keith, Sure that you do not have another program that maybe accessing the radio at startup? I have a very early 6700, SSDR v3 , and 8 panadpters open every time, also I checked the PC Ethernet throughput, with all 8 panadpters running I am showing about 7 mbit throughput , might check yours just as a check. Might also try leaving off starting DAX and SmartCAT. Just a thought. Dudley

Good find Keith, that was helpful, see? if we if we keep digging we will find something.

Good to know since I run 8 pans all the time.

Lars, Yes, Flex has confirmed there are two ways to get the lock up to occur on a 6700: 1) Have 8 panadapters and slices active with PC Audio enabled, shut down SmartSDR V3.0.19, then restart SmartSDR. 2) Have 8 panadapters and slices active and toggle the PC Audio button on/off. Either scenario will lock up a 6700 with SmartSDR V3.0.19. Work-arounds are to not use PC Audio, use 7 panadapters or less when PC Audio is enabled, or revert to earlier SmartSDR versions. They are looking into a possible fix for future updates. Keith - AE5XN
