SDR Sharp record

[moonbounce]

I just decided to try the record button on SDR Sharp and recorded a 194 MB file. Question, where is it? How do I recover it.

It 'should' be in the folder where SDR# was run from.

On my install on my 'D:' drive, it's here. 'D:\SDRSharp-1'

Just ran a short record test to verify that's still true.

Volume in drive D is 2T_Backup
Volume Serial Number is 4C9E-3A1C

Directory of D:\SDRSharp-1

Hello Rich,

If I might ask how did you arrive at that command? Is there a list of commands and or switches to use with SDR Sharp?

I tried the same command only my copy is on my C:\ drive and all I got was the message that it was not a recognized command.

Hello Rich,

A little technical, but .................... here it is.

That's an old DOS trick.

It makes it easy to 'capture' the results of a 'DIR' or many other commands into a file rather than watching it scroll up the screen.

You type in the following command in a DOS window and the resulting data is written to a file of your choice.
(Since my folder for SDRSharp is 'D:\SDRSharp-1')

Type the following line, verbatim:
Dir d:\SDRSharp-1\*.wav > Listing.txt

(By the way ...... adding ' /S' to the end of that command also searches in sub directories)

That redirects the results to a file rather than displaying them on the computer monitor. (It is NOT shown on the screen.)
In this case, any files with a filetype of '.wav' in that directory (or sub directory if /S is added) are written into a file named Listing.txt

You can then edit the file. And clip/paste from there.
You also sort the results or search within the results (or manipulate the results) for what you want if you are good with an editor.

Rich

By the way, you have to be careful not to search for filename/filetypes that are the same as your output file.
For example, if you search for all file types of .txt and your output file is also .txt, and you're within that folder in DOS, then you'll go into a never ending loop and it abnormally ends. Maybe even with a blue screen.
That's because it keeps seeing itself. ENDLESSLY!

Are you sure about that? In 30 years I've never seen any operating system fall over from such a fundamental flaw and command output piping is something I've done a lot.

To be sure I just opened CMD with Admin priv under Win 8.1 and it shows the file capturing the command output as having 0 bytes (which would be correct at the moment) there were no errors or infinite loops. Screen capture attached.

The second command "copy con touch.txt" tells the O/S to copy from the 'Console' (keyboard) to a file. Typed in some random characters followed by Ctrl+Z on a line by itself for the EOF marker. This was done so there would be another file with the .txt extension.

You overlooked my statement in the very first line.
“other commands”

Here is one case.

The file to be scanned:


The expected results:


After hitting control-break to end the loop:



Over 10 million lines found in a file that has only 22 lines!:

All I am getting is " Access denied" and that would be in my admin account. Also since my SDRSharp is on my C drive, I would assume that my command line would look like this?

Dir c:\SDRSharp-1\*.wav > Listing.txt

I did try it with and without the C but got the same results, access denied.

You don't have sufficient privileges.

When you go to open the DOS window, right click and 'Run as Administrator'
Then, it 'should' work.

“other commands”

I did indeed, apologies. This SCAN command that you used in your example, where is it from? I don't recall it being part of the O/S nor could I quickly find anything online. Seems like a flaw in the SCAN program.

Yep, it is probably a flaw in that program. But, if you understand it, you can live with it and work around it.
I've seen a few others with similar problems.

It's a program I've used since around 1985 or so and was an 'Internal Use Only' program at a company I worked for.

I use it a lot (many times every day) and it's faster and easier to use than Windows Grep for fast file searching and 'data mining'.

It doesn't have the 'robust' error recognition/handling that good software 'should' have. But for functionality, I have yet to find it's equal.

Thirty years ago, life was far less complicated and so was the software.

Rich

One quick example of what I use it for.
I normally log 11 or 12 scanners constantly.
Each of them creates a log file and a wav file every hour of every day.
So in a 30 day period, I'll have roughly 8,000 log files and 8,000 wav files.
Using that scan function, I can search through all 8,000 log files for any particular information in about 3 minutes and write all of the results into a new file.
Then I can examine or manipulate the data as I see fit.

If the other suggestions don't resolve your problem, make sure you have write permissions to wherever you are putting the file Listing.txt.

If I open a DOS window and do the following:
cd \users\jim\Desktop
dir c:\windows > Listing.txt

It works just fine. But:
cd \windows
dir > Listing.txt

Alternatively, from anywhere I could issue:
dir c:\windows > c:\users\jim\Desktop\Listing.txt



Produces an access denied error. As a 'regular' user I don't have permission to write to the C:\Windows directory but I do have permission to my Desktop directory.

It 'should' be in the folder where SDR# was run from.

Rich

I located the recording, but it's all noise. Any settings I must do to record properly?

My version is v1.0.0.1443, and I am using a RTL-SDR dongle.

Thanks.

 

[Voyager]

Are you recording audio or baseband?

 

[kk8]

Thanks a million! Didn't realize that's what Baseband meant. Perhaps it should be named IF?

Because you're telling it to create Listing.txt in some folder you don't have rights to.

Is there some reason why you don't just use Windows Explorer to look at the SDR# folder and its contents?
