Re: HF APRS Time Lapse Video -- Timeout Setting?

Adam:

Thanks for the info. I ran another timelapse and noticed that if a station isn't heard from after 30 minutes, it's removed from the map. It's remains in the station list for up to 2 hours before it's removed from the list. If a packet is received from that station before the 2-hour limit, the process above starts all over again. At least that's what appears to?be happening when viewing the time-lapse.?

I've attached a few screenshots to illustrate the time out sequence. Notice how the highlight color in the station list changes from white to Yellow after 15 minutes and then Red after 30 minutes.?

Neat time-lapse video.

I believe this has to be done via editing the xml file. I can't seem to find a menu item for it. Someone else may know where it is.?

<Stations.MinAge>80</Stations.MinAge>
<Stations.MaxAge>120</Stations.MaxAge>

I believe those numbers are in minutes.

All:?

I recently recorded a time lapse video showing APRS-VARA activity on the 30-meter band (see below). The condensed video is only a few minutes long, but the actual recording time was approximately 8 hours. When I played it back, I noticed that stations would periodically disappear from the map over a certain amount of time and some would then reappear.?

My guess is that this is due to the time-out feature, which assumes a station is no longer active if no packets are heard over a given time period. It's obviously a useful feature, but I was wondering if the timeout can be modified for demonstration purposes i.e., video demos???
