> The program was borrowed from the open source software K1JT. Only decoders and generators were used from K1JT - WSJT and were rewritten to C ++. Almost the same location of controls was used for easy operation. The software is fully compatible with the modes in WSJT software. The visual interface is QT4.6.8. All required libraries are compiled statically and are embedded in the body of the software. Additional libraries are not necessary. All settings and configurations happen immediately and do not need to be restarted, for example changing the sound settings or rig control.

- "View Log" You can open open simple log program.
- "Overwrite Locator Database" Overwrite the existing locator database. For example, when a new software version is released, you can overwrite database from your old software. The locator database are in the file MSHV_XXX/settings/database/msloc_db.dbmh of your old version.

- On menu Palette:

- Palette menu changes the colors of the decoder displays.

- On menu Mode

- Mode menu changes the working type.

- On Menu Decode

- Fast MSK144, is used for slow CPU speed PC.
- Norman MSK144, is used for more sensitive decoding.
- Deep MSK144, is used for fast CPU PC.
- MSK144 RX Equalization Off.
- MSK144 RX Equalization Static, static coefficients for equalization.
- MSK144 RX Equalization Dynamic, coefficients for equalization from you receiver.
- MSK144 RX Equalization S And D, Static and Dynamic together.
- Single Decoded Signal JT65, is used for synchronize only one signal.
- Max 4,8,16,32 Decoded Signals JT65, is used for multy signals synchronization.
- Tune Decoder Aggressive Level and Deep Search Aggressive Level.
- Switch VHF/UHF and HF features for JT65 decoder.
- Enable Averaging JT65, is used for very weak signals need minimum 3 periods to activate average decoding.
- Enable Deep Search JT65 recommended only for VHF/UHF bands.
- Enable AP switch for a priory decoding features.

- Displays area

- The program contains two displays which show the received signal. When display 1 is filled for the period of 30 seconds the information is automatically moved to display 2. Then display 1 starts filling again with new information. A line graph for the time in seconds is being shown at the top of the display. The middle part of the display presents the signal as a waterfall. The graph below presents the signal strength indicator.
- To decode the received signals from the display, click with the mouse in the center of the received ping. When you press the display, two lines appear that show the region of decoding. Pressing the right mouse button makes the region twice larger than pressing the left one. No matter which display you decode, both are always active.
- To the right there is a slider to adjust display settings. Please, in the Windows Record Control mixer, first adjust the noise level from the receiver by positioning the stretch indicator at 0db strength. Secondly, adjust the displays using the Tune Displays slider to show dark blue color with small green dots, as shown in the picture above.
- Under each display there is a button to help you save the data in file. Files are stored in the directory RxWavs. The button displays the file name. The file name contains information about the correspondent's callsign, working type, year and time. There is an exception if the callsign is (/), it is replaced with the word SLASH, for example LZ2HV/P will be saved as LZ2HV_SLASH_P. This is necessary because (/) means the creation of computer path to directory and you cannot save the file.
- For small display resolutions (eg. 800x600 pix) in lefthand display area, button 2D/1D - changes application to work with two or one displays or shortcut F10 for this function, and button D1/D2 - switches displays, if working on one display or shortcut F11 for this function.

- RANDOM QRG is the offset for random contacts in 3 digits max.
- ZAP function: Filter out birdies (narrowband signals of approximately constant amplitude) before attempting to decode. This function requires 10s. of receiving period before beginning to work properly. The filtering period does not show in the display area.
- TX/RX 30s is a period of work 5s, 10s, 15s and 30s.
- Sh option in MSK144 mode (e.g. MSK144 + Short Reporting).
- Label "RXF/RXS" - when the Label "RXF/RXS" or key F9 is pressed, RXing works only during the first or second period.

- Text Messages Panel

  - All text messages long 1-28 characters are in this panel. You can write them by hand or generate them by macros. When you press any of the buttons TX1... TX7 its message transmission begins immediately.
  - When changing the radio buttons, the message is not transmitted immediately and only shows which of them will be transmitted in the next period.
  - Slider "RX Level Correction" change input sound card level +/-12dB.
  - Slider "TX Level Correction" change output sound card level.

Its range is from 1 to 5, this is the number of your emitting signals (TX). It is recommended that you use only one TX Slot if you are not a DX expedition.

  > The next spin box is "Max Time:". Its range is from 1 to 10 min, this is a how many times the application responds to a single user, if there is no response from the user. The next combo box is CQ types: CQ, CQ DX........Free CQ. To use the Free CQ option, first write a message, then press the button (USE). A valid message must to contain a valid call sign.

  > Check box "No Dupes": The application checks for calls for possible duplicate QSOs.
  > Check box "SMsg": Allows TXing special message e.g.(OZ2M RR73; R5WM <LZ2HV> +05).
  > Check box "Auto Sort": Auto sorting of Queued is activated if Dist column header is marked.
  > Check box "CQ on free slot": Allows TXing CQ on free slot.
  > The next two buttons are intended for clearing of users Queued list and Now list.

  - Tab Now:

  > Tab Now contains the users you are currently working with.

  - Tab Queue:

  > Tab Queue contains the users waiting for a response from you. You can sort them by call or distance by means of clicking on the header column .

  - Working:

  > To start working, you need to set up everything in the Settings tab, and then find room for your CQ by a single-clicking on waterfall and pressing the TX=RX button (small red markers in the top frequency scale).

  > Then, you need to unlock TX and RX (uncheck LTR), and, by a single click, adjust yout RX frequency slightly up.

  > IMPORTANT: the green horizontal line in the top frequency scale is your receiving bandwidth. If you have to change it, use the "DF Tol" spin box. Then, change Auto from off to on and application starts working. If you have to switch fast between "Multi Answering Auto Seq Protocol" and normal work protocol, press shortcut Ctrl+` (Switch to US Keyboard, for Ctrl+`, the button is below the Escape button).

  > After QSO application finishes, it will automatically save QSO into the Log. In the Log widget, in Column comment, you will see the MA QSO abbreviation. In this protocol, this is the method for marking QSO connection type.

  It is recommended that you use only one TX Slot if you are not a DX expedition.

- Log program
  - In the simple log program you can add, edit, delete, find and sort QSOs. You can set the receiving report in the RX RPT box . From menu Band, you can choose the band so it is correctly written in the simple log. Sorting of logs in simple log can be done by clicking on the headers of the columns. To return to the default view, click the Default Sort button.
  - From the "Add Log" menu you can add contacts to your log. For example, when a new software version is released, you can add the contacts from your old software. The contacts are in the file MSHV_XXX/log/mshv.edil of your old version.
  - In Log Menu there is Export QSOs in ADIF format ("Export Selected In ADIF" or "Export All In ADIF"). Destination of exported files is in ExportLog directory.
