The default program directory in the installation package is usually C:\Program Files\FSM . It is chosen to be consistent with Windows installation conventions and is a good choice.
FSM can be installed in a directory of your choice, and it does work properly.
Almost ALL of the support questions that I receive are from people who install FSM in another directory, and their problem is not FSM, it is related to their understanding of where the files are located, and since they often don't know where they are now located (the primary problem), I can't help them other than to advise them to reinstall FSM in the default directory so that at least I know the location of the files.
Because of the time wasted on resolution of these problems, I cannot give assistance to resolve problems where FSM is installed elsewhere than the default offered by the installer program. If you have problems, reinstall FSM using the defaults, see if the problem still exists, and if it does, then contact me.
If you think you have a need to install FSM in other than the default directory, read "Starting FSM in a different directory?" and "How do I get FSM to start with a different profile?".
My own practice is that:
FTF is designed to read plain text emails. Do NOT send HTML formatted emails to FTF.
FSM can be associated with .fsm files so that double clicking a .fsm file or a shortcut to a .fsm file will start FSM using that profile.
Go to menu "Options / Associate .fsm files" and click it to set the association up.
Once the association is created, profile files (.fsm) are a very convenient way of starting FSM with a particular measurement configuration. The menu folder below shows how to conveniently organise profile shortcuts. (See also Adding a submenu to the Start/Programs/FSM menu for FSM profile shortcuts.)
The properties of a shortcut are shown in the figure below.
By default, FSM uses a file named FSM.fsm in the Current Working Directory to store settings between sessions.
You can specify an alternate profile on the command line by using the positional argument <ProfileName>. This argument can be set in the Properties page of a shortcut (or Icon). See the example below, the shortcut name is "A-7MHz", it requests a profile of "c:\FSM\21MHz.fsm", and it starts in the "C:\FSM" directory. Note that the "Start in" directory is different to the directory containing FSM.exe, this makes it convenient to save results file in a directory separate to the program directory, which is a really good idea. Note that if you do not provide a path name for the profile argument, FSM will use the "Start in" directory for the profile.
You could use separate "Start in" directories for different projects and depend on the default profile file ("FSM.fsf") in each directory, or you could use several profile files explicitly in a "Start in" directory. The figure below shows how to specify the profile file on the command line.
The best mechanism for starting with a specific profile is to use the facilities described in the topic on association.
Profile files are in standard Windows ini file format. They are text files and can be copied from one computer to another. They can be safely edited with a text editor, but be aware that the field sizes are limited in FSM, and the value associated with a particular key may be truncated when loaded into FSM, and FSM will save the truncated value back to the profile.
All instances of FSM use the same shared Windows sound resource, and they use it during the time after the Step 1, Step 2, or Step 3 button is pressed and the "Working" window is displayed. Only one instance can be "recording" sound for measurement at any instant, so if you attempt to start a recording in one instance while another is "Working", you will get an error message that the sound resource is busy and you will have to retry it when it becomes free.
Each instance of FSM uses temporary files which are unique to the instance. The measured and calculated results will always be correct for the settings visible on the form.
If multiple instances use the same working directory and profile name, then the values read will be the values last saved to that profile by any instance using that profile. An instance of FSM only saves to the profile when it is closed, or when a new profile is opened from the menu.
If you intended to make a series of measurements on say, three frequencies over a couple of hours with one receiver and three different aerials, you could start three instances of FSM and fill in the scenario details for each configuration. (It may be wise to save each to a unique profile.)
You would then perform steps 1 to 3 in each instance with the appropriate antenna connected to the receiver. You could then switch antennas and repeat Step 3 on the relevant instance of FSM from time to time, saving the need to rerun all of the prior steps.
If your test involved more than one receiver, you would also need to switch the correct receiver audio out to the sound card for each measurement.
By default, FSM will start in the directory containing FSM.EXE.
This is not a good place to store your data files, such as saved results and profile files.
You can specify an alternative working directory in the properties of a shortcut, see the topic Starting FSM with a different profile for how to set a different working directory.
FSM may be started in debug mode. Specific functions work differently in debug mode, do NOT use it unless directed. To start FSM in debug mode, insert the command line switch -d in the Target of the properties page for a FSM shortcut as shown below.
A convenient way to access multiple profiles is to:
Carefully follow the following procedure to peform the above:
You should now have:
Opening these profiles in the C:\FSM directory from any of the available options will start FSM in the C:\FSM directory, open the relevant profile, and data files will be save in the C:\FSM directory by default.
This is not only convenient, working in a directory other than where the FSM program files are installed reduces the chance of accidently damaging criticial program files.
