You can also build yourself a neat little interface Key your transceiver via the RS232 serial Com Port, or key your MRP40's menu under 'Options - Tx-Settings.'Ģ. PTT via Com Port by selecting the check box named 'Activate PTT pin' in Note: When using AFSK for sending, one can activate the

Sending speed, so a minimum bandwidth is occupied, especially for QRS The riseĪnd decay times of the CW-signals are automatically adjusted to the Sine waveform and a smooth envelope, so no annoying key clicks. Recommended: Use AFSK (audio frequency-shift) keying by sending CWĪudio to the transceiver from the computer’s sound card.

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.
