Starting SmartSDR with a (Win 11) Batch File

Jim KJ3P · April 22

Under Win 10, I always started up SmartSDR and a couple of helper apps with a single batch file. However, the same batch file doesn't seem to work under Win 11 (the helper apps start OK). This is the line that worked OK under Win 10:

C:\Users\kj3p\xxxxxxx>start C:\Program Files\FlexRadio Systems\SmartSDR v4.1.5\SmartSDR.exe --serial-xx-xx-xx-xx

Any ideas?

I would drop this question into an AI like ChatGPT and have it build the Batch file for you. I have found that to be very successful.

Hi Jim, here is the line in my .bat file that works under Win 10. Try this in Win 11 and see if it works:

Start "" "C:\Program Files\FlexRadio Systems\SmartSDR v4.1.5\SmartSDR.exe"

The double quotes around the executable path are missing in your example. I can't remember if they are absolutely necessary, but eons ago I found an example with them and have been doing it this way ever since. I forget what the null parameter is at the beginning, but that might be the issue as well.

I believe the quotes are necessary if there are spaces in the path.

I finally got the batch file working sing my original coding, but I think it had something do with OneDrive hosting the batch file. I stopped the (default) backup of the desktop screen, and ran the batch directly from the computer. Works fine, but I can't explain why.

Thanks for all your help!

This is not the only issue with Onedrive!

Two notes: With SmartSDR 4.2.x the path changes. And, if you want to avoid your batch file trying to start something that is already running, look at this snippet:

REM ===============================================================
REM Next, MAKE SURE Flex-DAX and Flex-CAT are running.
REM ===============================================================
REM Check if already running:
tasklist|find /i "DAX.exe" >NUL
REM If not, go ahead and start:
if errorlevel 1 (start "" "C:\Program Files\SmartSDR v4.2.18\DAX.exe")
…

You can do the same for any other programs:

cd C:\DDUtil_V4
tasklist|find /i "DDUtil_V4.exe" >NUL
if errorlevel 1 (start "" "C:\DDUtil_V4\DDUtil_V4.exe")

cd "C:\Program Files (x86)\FRStack3"
tasklist|find /i "FRStack.exe" >NUL
if errorlevel 1 START "" "C:\Program Files (x86)\FRStack3\FRStack.exe"

Yes, I eventually discovered that the root folder for SmartSDR 4.2x had changed.

And thanks for the batch snippet…I'll give it a try today. A frustrated coder wannabe, I love these things that I actually understand <g>.
