MRP40 Morse Code Decoder & Sender

Deutsch       Japan

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.

There are two ways to 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 in SSB transmission mode. The signals generated by MRP40 have sine waveform and a smooth envelope, so no annoying key clicks. The rise and decay times of the CW-signals are automatically adjusted to the sending speed, so a minimum bandwidth is occupied, especially for QRS (slow sending). Note: When using AFSK for sending, one can activate the 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, or key your transceiver via Soundcard output. This requires an interface box between PC and transceiver. You can also build yourself a neat little interface like suggested in QST Magazine issue 02/2007. Click here and study the article.

To ensure galvanic isolation between computer and transceiver, we recommend using an interface box from SignaLink

Windows 7 specific instructions:
Locate MRP40 at it's Program folder location  for example "C:\Programs\HamRadioSoftware\MRP40 Morse Decoder V62\MRP40v62.exe"
Right click on the MRP40v62.exe file to access the properties
In 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:\Programs\HamRadioSoftware\MRP40 Morse Decoder V62\MRP40v62.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.
