SmartSDR (2.3.9) DAX and CAT trouble

  • 1
  • Problem
  • Updated 3 months ago
My SmartSDR install went haywire yesterday (for no apparent reason, but then, Windows doesn't really need a reason to screw something up).

The summary is that I have a bunch of extra DAX devices, many with wrong names.  I have been unable to remove them, even following the detailed uninstall and install instructions.  However, SmartSDR does stream properly for slices A and B, i.e. the first two DAX devices.

My CAT COM ports are also completely messed up.  I cannot get rid of those, either.  However, I was able to work around this issue by using VSPE virtual ports instead of the Flex VSP ones.  However, I would really like to be able to use the Flex ones.

SmartSDR itself is operating properly.

I tried everything I could think of to uninstall and re-install SmartSDR, including DAX and CAT, to try to clear this up.  I followed the detailed instructions for complete removal.  I also removed everything in the registry that was DAX and CAT related.  I did numerous reboots (about 20) after various steps.  I deleted everything in the Program Files Flex directory after uninstall.  I removed all hidden devices (DAX and CAT).  In short, many of the steps I performed should have removed everything so I could do a clean install.

Like I said earlier, I am running digital OK via CAT workaround, and at least 2 DAX channels streaming.  But I would really like to get this fixed.

Can anyone give me suggestions, NOT including reinstalling Windows, for resolving this?  I've already reinstalled Windows and all my programs once a few months ago as a last resort for fixing similar problems.  That was a HUGE headache, as I had to reinstall and reconfigure over 200 programs.  I really, really, really do not want to have to do that again.

I guess I qualify as anyone, from what you've indicated, I see no reason to reinstall Windows. If you contact me via #Flexradio IRC, I think I can fix your device problems for you , and also try to teach you what the problem really is. the link to the IRC channel is in my post signature, your callsign works best for the IRC nickname. Some of what need to be done needs a one on one, in realtime, direct approach. I'll keep an eye on the IRC channel, waiting for you to join, so we can try to get started.

What Jay said. You very seldom ever need to reinstall Windows.

Jay -

I really appreciate the help.  I am tied up on a net until about 7pm tonight.  Is it OK to look for you after that?

Yes, I should be available, barring any major timezone differences.

Why the IRC chat???

I could just tell people to call me on the phone, to get this started, but I will not publicly post my phone number, so that's impossible.

Or ...

We could try to use email to pass my phone number, but email doesn't always go thru, and  it's kind of a slow way to get setup. 

Using IRC to pass private info, can be a little more private, and it's a lot quicker.

The idea is to setup a Team Viewer session So that I can see, in real-time, what the problem is.

Or, if Teamviewer, isn't an option, to at least set up a voice connection, I prefer to use Google Hangouts, but a phone call would work as well, so I can try to talk people thru the repairs. I can talk a lot faster then I can accurately type. and you can interrupt me instantly since it's a live, private, one on one connection.

I use Teamviewer frequently, so that is probably the best way to proceed.  I also have a freeconferencecall.com account, so we could use that as well.  It provides voice, screen sharing, chat, etc.

Michael - tell that to FRS.  The first time this happened, I spent a good bit of time with support trying things they suggested.  Ultimately, they were the ones who threw their hands up and said that I would have to reinstall Windows.  My Windows installation was acting funky anyway, and I hadn't been able to find the source of the issues, so a reinstall was needed anyway, so their suggestion wasn't a big deal.  However, I've got everything running smoothly now, which is why I'd rather not do that again.

Thanks Michael and Jay for your input and help!

I have found that the cat reset procedure helped me gain control of my come ports.  I have had far fewer conflicts since I used the procedure.  you simply have to open up cat window and RIGHT click
on the remove tab.  Click on Reset VSPports.  Then restart SmartSDR and the radio.  Then do what you need with your PC and com ports.  Another procedure that has helped me, and is in some install instructions for installing  new com ports, is to unplug all current come devices.  Then plug in and get the new device working.  Easy to determine what com port the device is using if it is the only one plugged in.  Life has been easier when doing the above....

Jay - thanks for the hours of help last night.  I learned some stuff.

Pat - I just tried the CAT reset procedure and it resolved my CAT issues.

My DAX devices are still duplicated and mis-named in Device Manager, however, I can figure out the right one(s) to use in my various digital software.  So, for now, everything is OK.

At some point soon, I'll need to do either a Windows in-place upgrade or complete reinstall to fix sound issues that are obviously Windows issues.

Thanks, ALL for the help and suggestions.

Hi David, Glad I could provide some resolution to one of your problems.  One additional area of concern is what is in the registry, which also affects com port use.  I am not an Admin, so I rely on third part apps to help with the deeper problems.  I use a program called "Clean My PC" from MacPaw to do a number of correction and cleaning chores and it does a good job of fixing registry problems, which can cause stability issues in a PC.  No program is perfect, but this app gets me closer to stable operation.

I'll stay away from the registry cleaners for now.  I used a few in the recent past that removed things they shouldn't have, creating more of a headache.

Thanks.

I have never had that happen with "Clean my PC", that being said, It is best to be on safe side.  And yes there are a lot of bad PC programs.  In my case I was desperate to solve registry problems and my skill levels with line commands are non existent.
But some of the com port problems are registry related, especially with two com port Allocation (PC, FlexVSP) programs running.  The comport registry gets messed up. 
Any way good luck and smooth operating.

Update on DAX drivers: I was able to resolve this by doing the following:

1.  Using the uninstall.bat for each set of DAX drivers.
2.  Deleting ALL my other sound card devices.
3.  Using Device Remover software to remove any leftover sound devices.
4.  Re-adding the DAX devices ONE SET AT A TIME (i.e. IQ, MIC, RX, TX).  After installing each set, I went into Windows Sounds and renamed the devices correctly.
5.  Installing my other Windows sound devices, including virtual devices (VAC and WinRadio VSC).

By Installing the DAX devices first, and renaming after each group, I was ab le to get everything named correctly.  Also, once they were named correctly, then the other virtual devices installed with the correct names.  Every device is still duplicated in Device Manager, however, they show up only once in Windows Sounds.  I tested every device and all work correctly.

This process got me around the Windows 10 issue of misnaming sound devices.

What a PITA.  Windows, I hate you.

Oops, missed writing up a step: after removing all the sound devices, I also removed their drivers in the sound controllers section of Device Manager.
