MRP40 is a powerful and highly-effective ham radio software program that decodes received CW audio that has been fed to a computer’s sound card. The decoded text is displayed on the computer’s monitor. For transmitting CW, the program encodes keystrokes from the computer’s keyboard. Hams use MRP40 to send and read QRQ (high-speed) CW, to help read weak DX signals, and to improve CW contest scores.
... With MRP40 you are number one on the air! ...There is now available a special SDR Version of MRP40 Morse Decoder for more info click here
There aretwowaysto transmit:
1. Recommended:Use AFSK (audio frequency-shift) keying by sending CW audio to the transceiver from the computer’s sound card.The rig operates inSSB transmission mode.The signals generated by MRP40have sine waveform and a smooth envelope,sono annoyingkey clicks. The rise and decay timesof the CW-signalsareautomaticallyadjustedto the sending speed,so a minimum bandwidth is occupied,especiallyforQRS(slow sending).Note: When using AFSKfor sending, one canactivatethe PTT via Com Port by selecting the check box named 'Activate PTT pin' in MRP40's menu under 'Options - Tx-Settings.'
2. Key your transceiver via the RS232 serial Com Port,orkey your transceiver via Soundcard output. This requires an interface box between PC and transceiver. You can also build yourself a neat little interface likesuggested in QST Magazine issue 02/2007.Click hereand study the article.To ensure galvanic isolation between computer and transceiver, we recommend using an interface box fromSignaLinkLocate MRP40 at it's Program folder location for example 'C:ProgramsHamRadioSoftwareMRP40 Morse Decoder V62MRP40v62.exe'Right click on the MRP40v62.exe file to access the propertiesIn the properties / compatibility table one must set: XP Service pack2
Vista-specific instructions:MRP40 can run under Vista only if launched directly from it's Program folder location, typically 'C:ProgramsHamRadioSoftwareMRP40 Morse Decoder V62MRP40v62.exe'Right click on the MRP40v61.exe file to access the properties tab and select XP Service pack 2 or 3. This need be done only once; however, each time the program is run, one should right-click the .exe file and select “Run as administrator,” unless the User has administrative privileges.
MRP4064: - PTT function can be disabled completely- Bug Fix regarding USB to RS232 Serial Adapter: Now proper timing of first 'Dot' during CW sending via ComPort- Typing the ESC-key will stop the ongoing sending action and clear the Tx text box- Mini Log Book integrated: A neatlitle tool to log your contacts.It automatically looks up previous contacts with recent call. It supports ADIF record format. To launch the MiniLogBook run MRP40 and click -Options -Show ... -MiniLogBook To learn more about comfortable operation refer to the Help Documentation. Run MRP40 and click- Help -English -User interface -Program Menu -Options -Show then scroll down to section 'MiniLogBook'
MRP4063: - Graphic Display improved:- now double dynamic range for signal amplitude: color transists from black into bule into light blue into white (see screen shot above)- now double frequency resolution: display of incoming signals is more sharp; much less side lobes visible.- now double time resolution: length of short dots is displayed more accurately
- Default text font size is appied when window is resized- Green Volume indicator for soundcard signal corrected:-the vertical display range now represents 1:1 the physical signal range of soundcard ( please keep volume moderate, avoid cliping at top )
MRP4062:- Bugfix: Click noise during sending via soundcard eliminated- Windows 7 Support added: Audio Control Panels (Mixer sndvol32.exe ) included in Installation PackageMRP4061:- Sending is continued even if you work other applications
- Tx sending via Soundcard Audio Tones added- Bug Fix for soundcard selection (Tx) done- Set Audio Tx Frequency equal to Rx Frequency(helpfull to perfecly match the frequency of remote CW station ( your tranceiver does Tx in SSB mode the soundcard audio out signal)
