![]() ![]() 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. ![]()
