![]() ![]() 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. 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 propertiesIn the properties / compatibility table one must set: XP Service pack2Vista-specific instructions: Mac running OS X 10.7 and using Windows 7 running in Parallels 7.Operating System: Win95 / Win98 / WinMe / Win2000 / Win XP / Win 7/ Snow Leopard / Parallels Desktop 5.Click hereand study the article.To ensure galvanic isolation between computer and transceiver, we recommend using an interface box from SignaLink You can also build yourself a neat little interface likesuggested in QST Magazine issue 02/2007. This requires an interface box between PC and transceiver. Key your transceiver via the RS232 serial Com Port,orkey your transceiver via Soundcard output. 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. 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. A new feature automatic formats unspaced words read more.ġ.Automatic tracking of "drifting" signals (via AFC).Very good decoding of weak, noisy and fading signalsAlmost 100% copy in heavy CW contest conditions and local QRMDecoding now better than famous MRP37 Morse Decoder (MS-DOS version, no longer for sale!).There is now available a special SDR Version of MRP40 Morse Decoder for more info click here With MRP40 you are number one on the air!. Hams use MRP40 to send and read QRQ (high-speed) CW, to help read weak DX signals, and to improve CW contest scores. For transmitting CW, the program encodes keystrokes from the computer’s keyboard. The decoded text is displayed on the computer’s monitor. 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. ![]()
