glfer is a GTK+ application that shows the input signal frequency spectrum in a waterfall display and can also control a transmitter to emit slow-CW (QRSS) signals. The signal to be analyzed can be acquired in real-time from the sound card or can be read from a WAV file. The signal spectrum can be computed using four different spectral estimators. The spectrogram display can be saved as an image; you can choose to save the entire window, or select a rectangular region to save with the mouse.

Release Notes: A small change was made to allow you to select any device in /dev as the control device for the TX, so people using a laptop or netbook with a converter from USB to RS232 can enter /dev/ttyUSB0 or similar.
Release Notes: This version corrects a small bug affecting the FFT window type selection when using the saved application preferences that was present in version 0.4.0 and earlier.
