ADS-B changes (was: Re: [yaac-users] next YAAC build#198 created 2024-May-21)
The ADS-B timeout parameter is in the port configuration panel for that port type. It's a control that allows you to set a time between 1 to 60 minutes. So go to File->Configure->Expert Mode, go to the Ports tab, select the row
for the ADS-B port, and click Edit.
Alas, there is a bug in the rtl_adsb program where it may not die when the YAAC port is closed (either by editing the port or exiting YAAC), so you may have to hand-kill it and re-open the port.
As for the age times, those are the times since an ADS-B sentence was last successfully heard for a given aircraft. Note that keyword "successfully"; if there is a bit error in a received sentence causing a checksum failure, the
sentence will be discarded and not counted as received. Distant aircraft will probably have higher error rates, causing slower updates.
Hope this helps.

Thanks for the update, Andrew, especially for the attention to ADS-B.
In searching through the new version, I haven't located the part about?
" 11.
in the ADS-B plugin, set the inactive station time interval separately
for
aircraft, with a default inactive-before-purge time of 5 minutes
and
a maximum of 60 minutes."
Where is that located? I went to View>Aircraft>Filter but it appears to be the standard filter settings for all stations, which I have set to 1 hour.?
This is in the truck, running a Win 11 box. The truck is parked. I have a/c that are now well over an hour old and (what i think is dead reckoning?) still showing as giant skidmarks %^)
Another thing I notice is that updating the screen seems to be at random times (the following is seconds after the top of the minute): 50 55 02 35 58 08 15 20 52 55 17 35 44 56 07 20 28 38 47?
Since there are sometimes as little as 3 seconds (52 to 55) and other times as much as 33 seconds (02 to 35) between screen updates, it doesn't seem to be a matter of processor overloading.?

next YAAC build#198 created 2024-May-21
next beta build#198 of YAAC ("Yet Another APRS Client"), created 2024-May-21
downloadable from
or
changes and updates include:
1. assorted changes to improve performance and reduce JVM heap fragmentation
and garbage collection overhead by reducing the number of transient
objects created.
2. update Javadocs to indicate in which Provider API version number new
functionality was added.
3. ensure that packets originated by the local station are not digipeated
or Tx I-gated by the originating station.
4. update the ?YDBG query handler to add an option for listing the plugins
in use by the queried station.
5. clean up port beacon name selector so duplicate beacon types don't get
registered to a port.
6. fix the Heard Station table view to optionally use the current filter
settings to calculate the table contents.
7. fix the line-of-sight window to use smaller units for lines of sight
over a short distance.
8. when saving and loading polyline definitions in the Draw layer, actually
honor the control that identifies whether the CSV file is in lat,lon
order versus lon,lat order, and report an error if the user picked
the wrong ordering (identifiable by a latitude exceeding +/- 90 degrees).
9. re-optimize the OSM importers to reduce the likelihood of excessive
garbage collection crashes on faster systems by reducing the number
of transient objects being created.
10. improve the documentation for timeslottable APRS ports.
11. in the ADS-B plugin, set the inactive station time interval separately
for aircraft, with a default inactive-before-purge time of 5 minutes
and a maximum of 60 minutes. Also display the distance and direction
of the aircraft relative to the YAAC station and the current
transponder squawk code.
12. in the AIS decoder plugin, ensure stale vessels are properly purged
from the system the same way stale APRS stations are purged. also
improve map symbols for some types of marine vessels and navigation
aids.
13. in the AREDN plugin, fix issues with AREDN nodes whose names exceed
the maximum length of APRS Objects, so that there aren't problems
with similarly named AREDN nodes on the map. also fix errors in the
calculation of line-of-sight obstructions.
14. correct error in Maven assembly of the distribution ZIP file.
15. add debugging support for sounds plugin playback of recorded .wav files.
In addition, the imported version of the 2024-May-12 snapshot of the
OpenStreetMap database is now available for download.
Enjoy!

Re: Configure Digirig on Windows 10 for YAAC
Just to be clear, you don't need a hardware TNC - only the soft TNC as Andrew pointed out. The DigiRig connects and talks to the radio, The soft TNC talks to the DigRig, and YAAC talks to the soft TNC.? You should be able to use either an AGW or KISS over TCP interface in YAAC to communicate with the soft TNC.
73, Lee K5DAT
Thank you all for your replies.
I did not realize I needed a software TNC as well.? I will work
on this.
Again, thank you !

More than that, it also does CAT data on the same COM port.

Bear in mind that a DigiRig is
not a TNC; a DigiRig is a sound card interface to a radio,
with a serial port used solely for PTT control.
You will need to run some sort of software TNC program to
use a DigiRig for APRS. Since you are using Microsoft
Windows, you will want to use AGWPE, UZ7HO Soundmodem, or
Direwolf. Once the software TNC is working with the DigiRig,
you can config YAAC to use an AGWPE port to connect to the
software TNC.
Hope this helps.

Hi All,
I have a iCom IC-8000 and Digirig interface on a Windows10
box, and I am having trouble getting YAAC to work.? I have
set up a port for Serial_TNC in KISS Only and TX is locked
on.? I have set RTS on and YAAC throws java errors.
Has anyone met with success using a Digirig on Win10?

Hi Andrew -
View>Layers>Show age was and remains on. The time since last position update is always displayed in small text below the main label. However, the value rarely changes.?
If I do Locate>(some a/c callsign)>OK then for the time during which the locate arrows are flashing all the on-map and in-range a/c icons on the screen update every second or so, consistent with my ADS-B browser window display. Once the arrows stop flashing, everything goes back to static.
And by static, I mean irregular but significant durations of time (120 sec? More?) pass between map updates. I assume that's either some process YAAC is doing for its own reasons or perhaps since I tell the map to stay centered on me. Even when I'm parked, the GPS dithers a bit, maybe it's enough to force a map re-center. But the a/c generally move several miles during that time.
Something else that would be nice would be to be able to set the persistence since last position update. Right now I think the ADS-B items may persist as long as any other thing, in most ADS-B instantiations 50-60 seconds without an update tosses the object off the list.
Oh, hey, one more item. While I can change the displayed font size, which is helpful especially on my mobile display, is there a way to bold the icon text? The text line widths are about the same as the background map lines and they all blend together. Maybe bolding would help me.?
I look forward to any enhancements!

Hmmm....? Sounds like I forgot to refresh the map when the position of an ADS-B station changes its position.
You can work around this by checking the menu choice View->Map Layers->Show Age. This adds a small-font display of how long since the last update for each station or object. Since that has to be updated regularly, that should cause the station positions to
be updated more frequently.
Hope this helps until I can get the fix out.

Greetings Andrew -
Thanks for integrating an ADS-B viewer into YAAC. I run an ADS-B receiver in the truck, and especially when I'm out in the middle of nowhere it's nice to be able to ID aircraft that happen by. I was using the browser interface to my ADS-B program running on
an RPi on the truck network, but now that I have YAAC going I can watch there as well!
YAAC is running on a W11 Pro box in the truck, connected to the same truck network.
I've been noticing that a/c icons sometimes rarely move on the map unless I rescale the map or refresh it in some way. For instance, SWA5641 is moving past me at about 20ft and the "Monitored Aircraft" list shows the lat/lon updating once a second or so, but
the icon on the map rarely if ever moves, and it always shows a staleness of "0s". That's just one example, there are dozens on the list many moving quickly, but letter to nothing moves on the map. Sometimes, maybe, they update quickly (like if I do a locate).
I did a search for ads-b related stuff on this reflector but didn't see anything about tweaking map update rates. Could it be that YAAC is just overwhelmed? I'm seeing over 350 a/c right now, according to the list.

Re: YAAC and AIS-Catcher?
Hmmm... that's odd. Are the AIS stations remaining on the map and the Station/Object List, or only on the Vessel list?
I do need to tweak the Vessel list so it supports the Clear Real-time Table menu option.
