How does PropNetPSK automatically apply “Good Amateur Practice”?
According to the FCC (as quoted by the ARRL), “Good amateur practice is a hard thing to define. It’s operating with the realization that frequencies are shared, that there’s going to be occasional interference and that’s no reason to become hateful and paranoid.” With this in mind, the PropNET client software (PropNetPSK) includes a component that assures that the transmitting frequency is clear before a transmission takes place. There are two layers of transmit-control strategy presented. Within the PropNetPSK client, there is a transmit watchdog timer that will force a transmission to cease after 60 seconds. Additionally, PropNET participants are strongly encouraged to employ hardware time out timers if their transceivers have them. PropNetPSK will listen before transmitting and hold-off transmitting until it perceives the frequency is not in use. Of course, there is always room for improvement. Participants are encouraged to suggest new ways in which good amateur practice can be app
