Re: Strange Position Reports
There's a pretty good way to remove the mysteries of APRS... Look at the packets being sent by a station and received by your station. I can't see the packets being received by your station unless you show them to me, but I can look at what is being sent... ? 2020-01-06 18:32:15 MST:?>APTT4,WIDE1-1,WIDE2-2,qAR,:T#420,125,070,255,105,083,00001011 2020-01-06 18:37:18 MST:?>APTT4,WIDE1-1,WIDE2-2,qAR,:>KI7RUS-13?Cliffside?Launch?HP?WX All BAMBAM is sending is status packets and telemetry...? It's just a noise maker... there's an i-gate within simplex range that can gate the WX packets, and the 3 hop status messaging is just a waste of resources. ?? The position report that heard may have been heard years ago. stores information for a very long time. You can send your telemetry definitions once, and will keep them in memory for years. Transient stations that come on every so often don't have that long term memory. BAMBAM is also very naughty, using a WIDE1-1 path, especially when it is located less than a mile from the JUNIPER digipeater. Why is it asking for assistance from a home fill-in digipeater to get heard by a main digipeater less than a mile away? Especially when there is evidence that ALAKES locates over 200 km away can hear BAMBAM direct? NICOLI sends out positions reports via local only, and telemetry via a single hop. ?? 2020-01-06 17:57:18 MST:?>APRS,WIDE2-1,qAR,:T#050,189,098,005,055,173,00000000 2020-01-06 18:06:24 MST:?>APRS,qAR,:!4605.21N/12327.31W#PHG2830W2,?ORn-N,?Fill-in?/?NA7Q?14.2V?76.2F?? YAAC is telling you that you heard the telemetry and/or status packets via the W7SRA digipeater, and with no location information, the best it can do is tell you that the W7SRA digipeater handled the packets.? NICOLI is operating in a much more network friendly manner than BAMBAM... it causes far less load on the system with conservative path settings. Most packets aren't going any further than onto the local airwaves. ?? Pretty tough to expect the computer to provide an accurate position for where the digipeaters are located with no position reports heard by your station. There are no real mysteries in APRS, just answers that you have looked for yet. James VE6SRV On Sun, Jan 5, 2020 at 9:06 PM Michael WA7SKG <wa7skg@...> wrote: My station = WA7SKG in Dallas, OR |
Re: Mini-Webserver
Per another user's bug report, I have found and fixed the issue with the mini-webserver, as of build#144 (05-Jan-2020).
However, due to the internal design of the graphics code in the Java runtime, you need to be running in graphical mode to be able to generate the map images on the webserver, as they are copied from the map display in the graphical UI of YAAC. |

Re: ax25 kiss tnc
开云体育Small world :-)
According to the doc available at the link above, javaAPRSSrvr
supports linux kernel ax25 networking, so in theory it should be
able to share a serial port / TNC with another APRS app. Once a
serial port is configured to be an ax25 interface it can be shared
by any app that supports kernel ax25 networking.
I've never used javaAPRSSrvr, but I wouldn't expect an APRSIS
server to need to connect to a serial port at all - unless it was
doubling as an IGate.
73,
Lee K5DAT
Hi. Unless the attached TNC is multi-threading, in respect to the
different clients connected to it via the single physical port,
you could get into bad trouble if one application changes the
configuration to suit it, but another application is confused by
the changes.
For pure RX only, probably not a problem, but if you have two
app's sending and receiving, hmmmm....
A KISS mode TNC is probably less troublesome than some, but
still not a good thing to do.
The same holds true when "sharing" a radio between data and
logging app's.? The fact that it can seem to work OK for many,
does not mean it is the correct way to do things.?? Put Hamlib or
Omnirig in the middle (for rig control) and it's much more
reliable, but you can still get into trouble if careless.
Regards.

Re: ax25 kiss tnc
Hello
Jean-Pierre, There is a program called ldsped that can connect to your ax25 interface and provide an AGWPE compatible interface that YAAC can use. Ldsped would share the serial port in this case with javaARPSSrvr at the ax25 layer.? Other apps like XASTIR support ax25 natively and can share the TNC as a result, but I expect ldsped to work with YAAC. It's been a long time, but I once used Ldsped on a Raspberry Pi and was able to share the serial port with aprx on the Pi.? Other apps not on the Pi could also share the TNC via the home wifi network thanks to the AGW interface provided by ldsped. 73, Lee K5DAT On Sat, Jan 4, 2020 at 1:52 PM Andrew P. <andrewemt@...> wrote:

Re: Strange Position Reports
开云体育The question mark icon is for stations with unknown positions. A station that sends a status message, telemetry, or positionless weather report first (as far as your station newly listening is concerned) means that YAAC doesn't know where to plot it or
what its symbol is. So YAAC guesses the station's location by assuming it's near its first digipeater (assuming the digipeater's position report has been heard). This feature is called "vicinity plotting".
Once YAAC hears an actual position report with an APRS symbol code from the station, it will change the icon and move it to the correct location on the map.?
While the station's actual position is not known, and either it wasn't digipeated and heard by an I-Gate whose position isn't known, or digipeated by a digipeater whose position isn't known, the position remains at latitude/longitude (0,0). The button
on the map toolbar with a big 0 on it will jump the map to that location.
Note that, if you don't like it, you can turn vicinity plotting off in the expert-mode configuration dialog.?
Hope this helps.

Re: ax25 kiss tnc
开云体育Note that you can't share the TNC between YAAC and javAPRSSrvr; only one program can own the serial port connected to the TNC.
Assuming you're going to have YAAC control the TNC, create a port of type Serial_TNC and specify the serial port device name connected to the TNC, your callsign-SSID, and the correct baud rate. You don't connect the TNC and YAAC to the Linux AX.25 kernel;
all the AX.25 logic is in YAAC so you don't use kissattach or /etc/axports.
If you want YAAC to forward the received packets to javAPRSSrvr, also create a port of type APRS-IS and connect it to your local javAPRSSrvr's client port.
Hope this helps.
