What's new in HamAlyzer 2.6:

Amplitude Range Slider: You can now slide the windows along the amplitude axis, like you could along the frequency axis. A second slider provides this function. When the amplitude range is scaled all the way out (0-100dB), this slider disappears, since it's not needed.

Plot window enhancements: There are now sliders located in the lower left hand corner of the plot window, so you can adjust the height and width of the plot window without taking your eyes off the action. Also, there's a 'gripper' in the lower left hand corner that you can use to resize the plot window with.

ControlStrip: Gone is the normal mode, where the controls are attached to the plot window. The floating toolbar is now standard, and a new mode has been added, called the ControlStrip. It's a very small strip of buttons, which provides access to almost all of the control window's functions, but in a very compact size. The only controls not there are the sliders (which are now on the plot window too, anyway), and the window type, fft size, and sample rate boxes.

Sticky forms: The control bar isn't attached to the plot window anymore, but now, if you drag it close enough, it will 'stick' to it, so that when you drag the plot window around, the control window goes with it. This is the case for the ControlStrip, and the options and overlay windows too.

Overlay enhancements: You click the show button to overlay a spectrum plot onto the plot window, and now it stays there, even if you hit the start button. To remove the overlay plot, just click the show button again. It now works like SpectraPLUS's overlay feature.

What's new in HamAlyzer 2.5:

Record to Wavefile: In the general options window, you can now select whether you want to analyze the data coming in from your sound card, or record it directly to disk as a wavefile. If you choose record, no analysis will take place, but you can always drop the wavefile onto HamAlyzer later to analyze it.

Resize bug fixed: Fixed a small but irritating bug where when you resized the plot window, the x axis slider would reset to zero. Not that big a deal, but sometimes when you get it just where you want it, it's very annoying to have to redo it everytime. Also, some hams have been asking for the ability to get a particular frequency range in the plot window. This bug fix will help with that. Now, you can slide the x axis slider so that the lower bound of the plot is where you want it, and then adjust the width of the window so the upper bound is where you want that.

What's new in HamAlyzer 2.4:

Overlay window enhancements: Traces which are loaded into an overlay slot can now be saved as data files to your computer's hard disk. Files are saved to the 'capture-to' directory, with the extension .fft. Just click on the 'save' button. Then, you can load in that .fft file and overlay it to the plot window any time you want. There's a tutorial in the help file on how to use this feature. Finally, the overlay window is now resizable. I did this because the default size is kind of awkward, tall and thin. Please note that I swapped the position of the 'capture' and 'overlay' buttons in the controlbar. I think its more logical this way.

New registration system: This is going to be very useful for those of you who like to have the newest and best version at all times. I previously had to recompile a copy of the program for each registered user, so that your name and call sign are in there. Now, each registered user gets a registration key which is separate from the program. So now, once your registration key is installed you can download the latest greatest version from the website whenever and as often as you want. There's no need to wait for upgrades anymore.

What's new in HamAlyzer 2.3:

Resizable Plot window: You can now resize the plot window to just about any size you like. This was really a big job, which is why it's the only feature implemented in this update.:)

What's new in HamAlyzer 2.2:

Log frequency scaling: There is now a log frequency scale option, selectable on the general options page in the options window.

Save to the png image format: Png is really the ideal format for saving HamAlyzer's plots. It's a lossless compression (which means png images look better than the same image as a jpg), and the same plot is smaller as a png than as a jpg.

Improved tooltips: Tooltips are the textboxes that pop up when the mouse is held over a control. You can select 'verbose help text', and the tooltips will display a brief description of the functionality of each control.

A help file: Writing windows help files is no easy task, and Microsoft does not go out of their way to simplify things. Hopefully, you find this file useful at some point.

Smoother X-axis scrolling: When you are scrolling along the frequency axis, it is now much smoother. This has been accomplished without any performance degradation.

What's new in HamAlyzer 2.1:

Overlay: The most important new feature in version 2.1 is the ability to overlay saved traces back onto the plot window. You can save up to 4 different traces, and each can be overlayed independently. Plot colors can be specified for each overlay. This feature allows you to easily compare spectra on the same plot. A brief tutorial on how to use the overlay feature is included.

Multiple plot markers: Also new in version 2.1 is the ability to add two plot markers simultaneously. You could only add one at a time previously. Right click the plot window, and a marker is drawn at that frequency. The frequency and amplitude information are written in the upper right hand corner of the plot window. Right click again, and a second marker is drawn, each marker is numbered 1 or 2, and the frequencies of each is displayed. No amplitude information is written to the plot window when there are two markers present. I tried it, but it started looking like an msnbc news broadcast; very busy.

Plot-capture enhancements: You can now save the fft-data to the windows clipboard. Data are tab-delimited, and can easily be pasted into a text file or spreadsheet file. You can now capture plot images using specific filenames. Also, the saved plots can be time/date stamped.

Color enhancements: The controls now adhere to windows color schemes. This is important particularly if poor visibility forces you to use a high-contrast scheme. Also, the background of the plot window can now be made either white or black.

Numerous enhancements and bug-fixes: Let's face it. All software is a work in progress. Many of the bugs reported by users have been addressed in the new version. Some notable ones include screen font/redraw problems, installation problems and the notorious runtime error 5 at startup. In fact, all known bugs have been squashed. In addition, the interface got a general facelift, and looks much more clean, and professional. The options window has been reorganized into tabbed pages, and overall, the program has a more professional feel (at least I think so).
