Any flushing of packets on timers can be based on when the program started. Timed sends of packets must not be synchronized to the system clock. The datagrams should be sent at a rate of no more than one every five minutes (unless the packet becomes full). The phrases used on this page do not line up with the terms used in the RFC. Note that as of Auguest 2018, sending the datagrams to will no longer work. Once the data has been gathered (and duplicate callsigns eliminated), it is formatted into UDP datagrams and transmitted to port 4739. To the discretion of the developer, but the goal is to minimize the number of database records! A change might be a move to a different band.Īuthors of PSK software are encouraged to implement the data reporting protocol as described in the next section. Precisely what constitutes a change is left Ideally, a callsign should be reported only once per hour if it has not 'changed'. Should be reported no more than once per five minute period. Highly desirable extra fields are theįrequency, signal to noise ratio and intermodulation distortion. The data consists of the calling callsign (at a minimum). The entire audio passband simultaneously and these can provide a great deal of useful This is not standardized as it depends on the details of the client. The data is gathered (somehow) from the client used to decode the PSK traffic.

There are a number of parts to this project, as shown in the picture below. Of reception records that can be used for research purposes. This can be useful in determining propagationĬonditions or in adjusting antenna and/or radio parameters. Minutes) see where his signal was received. The way that this would be used is that an amateur would call CQ and could then (within a few

If there wasĪ panoramic RTTY decoder, then I would encourage submission of that data as well. Most of the panoramic receivers have PSK decoders, which is what makes this work so well. Also, this project was originallyĬonceived for PSK use, but it is not specific to that mode. There is opportunity for innovation here. This is not meant to be the exhaustive list of patterns to check. The duplicate check is to make sure that the callsign is notĬorrupted. This is of interest to the amateur who transmittedĪnd they will be able to see where their signal was received. Run a client that will monitor received traffic for callsigns (the pattern 'de callsign callsign' or others) and, when seen, will report this fact. The way that it works is that many amateurs will Make those records available in near realtime to interested parties - typically theĪmateur who initiated the communication. This is a project to automatically gather reception records of PSK activity and then PSK Automatic Propagation Reporter - Developer Information PSK Automatic Propagation Reporter - for Developers
