Power SDR- PFN list corrupt

Mr Radio

I use a Dell M4700 running Windows 10. When I attempt to use ATU, I get a blue screen with message >PFN list corrupt< I tried both PSDR v 2.7.2 and latest KE9NS version with the same result.

Any suggestions how to resolve this problem?

I believe this was posted on the Flex forum on the Ke9ns website as well. Here's the response:

"First try running PowerSDR in DEMO mode. (Run PowerSDR with your radio turned OFF)

Make sure its stable when you play around in DEMO mode.

If it is stable in Demo mode, then it is related to 1394 FireWire.

I have a link on my website to "FireWire" and how to check for possible IRQ conflicts. If you find a conflict you can try moving the FireWire card to any other PCIe Slot (large or small).

But even if you do not have any IRQ conficts, some FireWire cards are more stable than others, and some motherboards are more stable than others when it comes to PCIe FireWire.

I have been running PowerSDR under Win11 for many months now without issues.
