DAX RX Streams Driver Error

Raul Pla · March 14

I spent weeks trying to configure HRD and gave up. (strong help never materialized) All kind of COM port errors. Now trying FLdigi which may be simpler. In the DAX control box there is an RX streams driver error. Not sure when it started.

I re-started SSDR but it wont help. Im just using 1 slice. Here is a screen shot. Anyone know what's up? Flex 6600 Windows 11. The radio is usable for CW and voice, OK with direct mic and key inputs.

Please open a support ticket.

I've opened a support ticket as well. Same error message popup since the cumulative Windows Security patch on Sunday. I've also done the usual recommendation to uninstalled and resinstalled SMART SDR, DAX, Drivers, turned off core isolation, etc.

After a week waiting on support from the help desk I went deep under the windows hood and down too many rabbit holes, all without success. I did learn that the root cause was a busted cumulative windows security update resulting in missing and corrupted DAX endpoints along with issues installing/removing programs, broken windows services (including camsvc) and many AppX registration errors

I decided to go ahead with an in place Windows 11 repair upgrade versus a fresh install. This way I could preserve my existing data, settings, drivers and related files.

Summary:

Download the Windows 11 ISO from Microsoft’s official site.

Mount the ISO (right‑click → Mount).

Run setup.exe from the mounted drive.

Choose:
- Keep personal files and apps
- Install Windows 11

Let Windows reinstall itself (20–40 minutes, several reboots).

Log back in — your environment is preserved, but Windows core components are rebuilt

All is good now.

My issues were solved by great help from Flex (DAX errors) and later from Ham Radio Deluxe (Com Ports) a couple of weeks ago. Now moving forward into making the PC handle the audio TX and RX.

What are you trying to do with HRD? I use it daily with my Aurora.

I like RTTY, SSTV and then **** and Contesia etc.. I think its all OK now. I just have to study more as HRD has a lot to learn before being adept. I did notice the print (copy) was quite poor on RTTY. I have seen somewhere that I could feed 2 sep receiver streams into HRD RTTY. However Im not going to do any contests. I do plan to add a second antenna on HF this summer.

I wrote H e ll where it became **** for Hellschreiber which is what I always called it.
