This version of FMSuite is designed for compatibility with SDR# 1921 and newer which use .NET 9.0. Please download this release from https://www.freqmgrsuite.com/. Known Issues: ? The plugin Scanner Metrics is not included in this release. Due to significant changes in the charting software that it uses a major rewrite is required. ? There is an issue in displaying some of the FMSuite plugins immediately after they are enabled in SDR#. Controls may be displayed out of position, overlaying other controls, or otherwise “mangled”. If this happens, simply restart SDR# and the plugins should be displayed correctly. This will be corrected in a future version of FMSuite. ? In the Data Tools Wizard, the download URLs for most of the online databases are out of date. When downloading online databases, enter the correct URLs for them in the supplied field. The new URL will be saved by the Wizard. This issue will be corrected in a future version of FMSuite. -Jeff

NEW DX101 VIDEO: Using Airspy's Co-Channel Canceller to Get More DX! (on AM AND FM!): https://youtu.be/Rk_0LMFAquk Premieres Monday at 6pm CDT! 73, Loyd Van Horn - W4LVH DX Central dxcentralonline.com youtube.com/@DXCentral

The problem: I remarked we have been spending a lot of time lately on problems that could be solved with much less effort if we all agree to adopt a minimum of discipline. As this mailing list grows, there will be less and less people interested in reading about problems they have already discussed, solved, and beaten to death in this same mailing list. Here's a quick reminder for everyone having problems with SDR software and computers. Unless you describe exactly what you are doing, in which context, with the exact hardware and software configuration, the odds of someone giving helpful advice are close to zero. The social media (and mailing lists) have the undesirable ability to amplify noise because there are naturally more people who have opinion than people who have actual knowledge. So please, read this post carefully. What do I do first? Use common sense. Determine if it is a support topic or a general discussion: Airspy Hardware related => Contact the support; Everything else goes to the list. For support related questions, prepare your list of "Steps to Reproduce" and send it by mail to The Support. For general discussion/best practices, try to avoid duplicates: Use the search bar to find an existing topic/answer/advice that solves your problem or improves your life. Don't jump on other's threads. Statistically, "Mee too" is never an actual "Mee Too". You are just making things difficult for all. Use separate threads for separate problems. A "segfault" has nothing to do with the noise from your Plasma TV or PC PSU. Try to keep the content technical. People from different cultures will read and ignore your untranslatable joke, but will definitely understand the tech stuff. How to report a problem: Steps to Reproduce Be precise Include exact data used during testing for easy reference, including hardware, OS and user software versions The steps have to be in the exact order Mention pre-requisites when applicable: Software dependencies, glibc, modified kernel, etc. Do not write composite steps. The devil is in the detail. Always recheck your steps to reproduce on a new system with the default configuration Make sure the sentences are short and unambiguous Thanks for reading to the end!

A few problems have arisen when some people install and use FMSuite v2.3. To aid in troubleshooting, please note these and ensure that they are not the cause of any issues you are having. Also refer to the Troubleshooting section of the User’s Guides. First off, *DO NOT INSTALL DOWNLOADED FMSUITE INTO THE COMMUNITY VERSION OF SDR#*. Sorry to shout but people aren't reading the installation instructions. Wait for CE to provide the newest version of FMSuite. *Problem: You see an error message regarding opening a database.* *Causes* : * Windows often blocks applications downloaded from the internet. When installing the software did you perform step 4 under “New Installation” in the Read Me First document? If not, delete the FMSuite folder and start over with a new installation and be sure to follow the instructions closely to remove the Windows block. * The database file may be in use by Windows or by some other program (anti-virus, backup program, etc.) Reboot your computer and try to start SDR# again. * The FMSuite folder contains a subfolder named “x86”. Some people mistakenly delete that folder thinking that since they are running 64-bit Windows the x86 folder is not needed, but that is not the case; it is required. Do not delete anything from the FMSuite folder. *Problem* : *SDR# loads properly after installing FMSuite, but you can’t see its plugins in the SDR# “hamburger” menu.* *Cause* : SDR# now has all third-party plugins in a submenu named “Plugins”. Look there for FMSuite plugins. *Problem* : *SDR# crashes when started. One or more error messages related to FMSuite are displayed.* *Cause* : One cause is the installation of FMSuite v2.3 into the Community Plugins package by Rodrigo Pérez, which already contains FMSuite v2.2. As stated in the Read Me First document, do not install FMSuite into the Community plugins package. *Problem: Using the Data Tools Wizard, importing a generic file fails with the error message “Line X has less than 35 columns”.* *Cause* : The documentation for importing generic files did not get updated for that 35 th column. In your generic file, add another value at the end of each row. It is named “SpectrumDisplay” and you can add the data “,0” (without quotes and with a zero). The documentation has been corrected. I apologize for any confusion. *Problem* : *Descriptions of frequencies on the spectrum no longer works.* *Cause* : As described in the User’s Guide, a new feature is the ability to selectively show some frequencies’ descriptions using the Edit window to checkmark that option. In other words you have to enable "Show descriptions of frequencies on the spectrum" in Preferences and then mark every frequency whose description you want to see using the Edit window. You may use the Bulk Edit feature of the Browse window to enable multiple frequencies at once. As always feel free to email me at sdrs.freqmgr [at] cox.net with questions or problems. Thanks for trying my software. 73, Jeff N8GJL

Can your plugin scan a list of specific frequencies in addition to a range of frequencies? Thanks, George

Anyone help? There use to be on the web a site for identifying radio signals I believe it was complied by someone called Sigi It showed in graphic form various traces of transmission with explanatory notes I have looked but cannot come across it Anyone can help !?

What does it do?

Greetings from Athens! Are there any utilities for Windows 11 that can measure the actual bandwidth / USB connection utilization (in bps) that an AIRSPY R2 or HF+ SDR uses together with SDR# software? 73 de SV1CDN, Dennis!

I have downloaded SDR# (SDRSharp) revision 1921 (2025-01-01). Which is the better file to run to run the program? SDRSharp.dotnet8 or SDRSharp.dotnet9 I have read the 'Frequency Scanner' does not work with Revision 1921? Is this correct? Also, where do I get the Plugins? such as 'Frequency Scanner'.

I upgraded from ver 1919 to 1920 to 1921. (1919 was running well) AudioRecorder is ver 1.3.5.7 When I went to 1920 I discovered that AudioRecorder was not reading the NameGroup or the name. In the SDRSharp.config file it shows AudioRecorder.FileName value="/ date / group / frequency + " " + name / time + " " + frequency" /> The display at the bottom of the AudioRecorder box shows \2025-03-23 \ No Group\283.375MHz Unknown\14-01-07 Unknown 283.375 MHz. So when the file saves it goes into the Unknown Folder without a name. It should go into a group name folder with a name on the file. So is this a problem with the recorder or with FreqMan? How is this fixed? The other major problem is the lack of audio level. The audio is almost unusable even after setting the level in the config file to 15. Using another program to increase the volume is not a valid solution.

It seems USB is noisy for power - especially from Rpi. Would this circuit help much with improving SNR on a Airspy HF? https://andybrown.me.uk/2015/07/24/usb-filtering/ Al -- "Beat it punk!" - Clint Eastwood

Hello, Can't begin to tell you how much time I've put into trying to configure FMSuite to work. Really would like to use this truly excellent program, as I have several years ago. Believe I'm using the latest vers. for SDR# vers 1921 (32 bit), and dotnet9, and have followed (all) the instructions. The latest error msg is: The SDR# configuration file doesn't contain the expected list of Step Sizes. Error:Shared.1 at FMSuite.common.shared.buildstepsizetable() at FMSuite.FreqMgr.FreqMgrPanel.FreqMgrPanelLoad(Object sender, EventArgs e) What, as usual, am I missing, or doing, or not doing, correctly ? Suggestions ? What next to try, etc. ? Probably worth asking again for the latest link to the latest version, please. Pretty sure that I am trying with the latest (for SDR# 1921), but perhaps not ? Thanks, Bob

For Jeff Knapp, Hi Jeff, I was trying to contact you, but I don't get response so I think that my messages go to the span bin or something like that. Please contact me.

Hello, No big deal, just falls into the "annoying" category. I have the radio menu set to AM As I scan the frequencies <30 MHz, or so, the AM selection changes to something else. Usually USB, but not always. How can I lock it to AM ? Why does it do this ? Bob

Greetings, Is there a way to lock the fractional resampling rate in SDR#? I can within uno and it makes a big difference in keeping the horizontal sync line from shifting when decoding WEFAX stations. I would like to use SDR# for decoding WEFAX. Thank you, George, NJ3H Redmond, Oregon USA

Does not change the status from 'Wake Up' to 'Acquired Device.' I can't check it with 1920, as I simply don't have it, but 1822 with the same configuration works fine. PC: Windows 7 32-bit. Maybe someone can share the 1920 version?

Today has not been a good. SDR# has crashed several times on both of my computers. All I have to do is change something, crash. Kind of takes the fun out of it. I don't know how to get the crash log if there is one.
