The Flex 3000 hardware is capable of 192 KB sample rate, and the KE9NS software
offers that option in the selection from revision OS onward added to 2.7.2
software. I run my Flex 3000 at 192KB, and for the most part it works fine.The
other part of this is the Firewire cable, the Firewire port, and the computer.
I have heard that even with the Flex 5000, there are some situations where 192
is problematic, and 96 is more stable.
I don't understand all the hurtles for a Firewire port to work, but perhaps
look at the CPU utilization. If your CPU is running over 20% at 96 Kb sample
rate, then perhaps it's best to just leave that setting alone. With my AMD
FX-8350 4G 8 Core processor, power SDR runs at 2-4% CPU load.
In fairness to Flex though, those that "brick" a Flex using 3rd party software
should not try to get free technical support from Flex to resolve the issue.

The FLEX-3000 will not operate at 192 K sampling rate. You cannot set
this from PowerSDR, so you must be using the Firewire control panel
which is not recommended.
