The Hamport software ( ) also uses this software interface and install it automatically.
Tuning is made via Omni-Rig software interface ( ), which should be installed separately. In this case auto-tuning by RIT is impossible. Take to attention that not every transceiver has programmable RIT. Tuning can be made by RIT or by VFO according selected option. Auto-tuning is made after click on spectrogram or ruler below. In this mode transceiver radio frequency is changed to consist RX frequency to TX frequency. The mode of automatic transceiver frequency control can be switched on by the " Setup > Tune RIG by" menu. It jumps to the peak frequency of the strongest signal after detecting a pause of more than eight "dots" in the current signal. The button " GotoMax" jumps to the peak frequency in the bandpass, The " AutoGTM" button switches on the automatic mode of "GotoMax". But this action is not made after click on the ruler under spectrogram. When the option " Setup > Interface >AFC at mouse click" is selected CwGet immediately adjusts the RX frequency to the nearest station after every mouse click on the spectrogram regardless of the "AFC" button state. User-selected frequency is shown at spectrogram by short red line. maximal deviation from last user-selected frequency. Second number is global deviation in hertzs, i.e. maximal deviation from current frequency. The first number is local deviation in hertzs, i.e. The numbers to the left of the AFC button determines the limits of AFC. The " AFC" button (auto frequency control) adjusts the long red line (working frequency) to the closest peak frequency. To move a visible part of spectrogram to left or right drag it by mouse with Alt key pressed. " Alt-7" hotkeys change frequency scale of spectrogram. To change the TX marker position, click on the desired frequency by right mouse button (or by left mouse button with "Ctrl" key pressed). It is used to help with zero-beat tuning.
The short thick black line is the marker of TX frequency. To change the working frequency, click on the desired frequency (probably a peak). Ruler under this window shows frequencies of sound spectrum.The vertical red line in the top window shows the working frequency of the filter. In the top window the current spectrum of a signal (blue line) and a peak detector of spectral components (green line) is shown. The working area of the program is divided into three windows, the sizes of which can be changed by the user by dragging the borders.
Decode morse code windows#
Special version for Windows Mobile exists. It is a software morse decoder that really work! No additional hardware required you need only receiver and computer with a sound card. It can work as narrow-band sound DSP-filter also.
Decode morse code code#
Simple software to handle devices connected to LPT portĪ program to decode morse code (CW) via sound card to text. A tool for monitoring popular web-cluster service from OH9W/OH2AQ Radio Club If you've read this far, you may be interested in the older version of this tool which does not attempt to adapt to the sound and also includes more diagnostic information.Cluster monitor. The volume threshold is the value (0-255) which the measured volume in the analysed frequency must exceed to be counted as a dit or dah. The volume filter (which uses dB) discards very quiet (very negative) or very loud (close to zero) sounds and scales the size of the remaining data. There are three parameters which are not automatic: the minimum and maximum volume filter settings and the volume threshold setting. The frequency can only be certain values and the closest allowed value will be chosen. If you want to fix the frequency or speed then click on the "Manual" checkboxes and type in your chosen values. In fully automatic mode, the decoder selects the loudest frequency and adjusts the Morse code speed to fit the data. From these timings it determines if something is a dit, dah, or a sort of space and then converts it into a letter shown in the message box. If the volume in the chosen frequency is louder than the "Volume threshold" then it is treated as being part of a dit or dah, and otherwise it records a gap (this is shown in the lower graph that looks like a barcode). The spectrogram of the sound is shown in the main graph along with a pink region showing the frequency being analysed. The decoder will analyse sound coming from the microphone or from an audio file.
