Re: Not receiving messages?
Ah, that's probably it then. The closest i-gate to me (about 3 miles) is receive only. I don't suppose there's any way to send a message and tell it not to use that i-gate? There are several others around me that should be able to pick up my transmissions.
Thanks

Re: Not receiving messages?
How are you sending the messages? Over RF? In that case, you're only going to see a reply if (and ONLY if) the I-gate(s) that forwarded your RF packets to APRS-IS are transmit-capable so they can put the responses on RF where you can hear them, and you are close enough to those transmit-capable I-gates to hear them without digipeaters (most transmit-capable I-gates don't specify digipeat paths on their IS->RF transmissions). That is the curse of the receive-only I-gate: it does not allow responses to be returned to the RF stations that initiated the conversation. Receive-only I-gates are using the fallacy that RF stations need to be copied to the Internet for Internet-only consumption but Internet traffic doesn't need to go back to the RF stations. APRS was originally designed as an RF protocol.

The radar raster map is out of position. It is centered about 100miles north of where it should actually be. Last night's rain over northern Missouri was showing up between Omaha and Des Moines.
Any ideas?

Base YAAC can't do that. But the smallscreen plugin can partially do that (since it was intended for mobile operation). It's a bit of a screen real-estate pig for desktop usage on a regular monitor, but it can store messages of your choice (not just the default ones I copied from my cellphone's default text replies on the car hands-free system). However, the smallscreen window's Messages tab is set up to send these as one-touch replies to other stations, so you might have to keep fixing the TO field. To configure your custom messages, you will have to use the expert-mode Configuration dialog to modify the list of canned messages. Hope this helps.

Re: Aircraft bearing (Heading) in ADSB decoding. Yes again, but with fix this time!
Actually, thinking about your proposed fix, it would have worked too, because you effectively did the same "flip around the 45-degree axis of reflection" as the "90 - " change did, without the extra integer subtraction operation. On the other hand, considering the computational cost of a double-precision atan2() function, an integer subtract is lost in the noise, and this is slightly clearer (as in, no one will look at the code a year later and say "hey, this code is wrong because the X and Y arguments are reversed, let's _fix_ it!").

Hi Andrew,
The adsbdecode plugin has a bug where the computed ground track based on aircraft velocity is incorrect. This results in the icon, bearing and track prediction being incorrect.
The issue is in AircraftState.java, line 496. The variables ewVelocity and nsVelocity are swapped. Another issue is the float variable is cast to (int) potentially making the heading up to 1 degree off.
I think the correct line 496 should be;
bearing = (int)Math.round(Math.toDegrees(Math.atan2(ewVelocity, nsVelocity)));
I have compiled and tested this locally and it produces the correct result. I’ve also filled out a ticket at sourceforge.

Re: Aircraft bearing (Heading) in ADSB decoding. Yes again, but with fix this time!
Actually, I just confirmed my error per my stated fix to your fix. I just realized that the only time I see ADSB traffic at a known altitude and bearing, it's because the wind is blowing in such a direction that the active instrument approach
that goes almost over my house is in use, and that flight path is directly along the axis of reflection between the current code and my fix. And my QTH is shielded from closer-to-the-airport traffic by the terrain. And I do recall that the other higher altitude
ADSB traffic did seem to be going in an odd direction (like perpendicular to the Atlantic Ocean coast that is a mere 75 airmiles from my home, when Port of Entry airports are between my home and the shore).
So please try my fix of 90 - old formula.

Just my $.02.

Actually, both the original code and your fix are incorrect, but might be showing almost-correct cases near the axis of reflection. That is because geographic bearing has 0 degrees at True North and goes clockwise, whereas
geometric bearing (returned by java.lang.Math.atan2(y,x)) has 0 degrees at True East and goes counterclockwise.
The correct formula (which I will be putting in the next release of YAAC) is
??????????????? bearing = 90 - (int)Math.toDegrees(Math.atan2(nsVelocity, ewVelocity));
This accounts for both the reversal in rotation direction and the different zero position (the following lines of code account for negative bearing angle, regardless of whether line 496 is correct or not). You will find this code pattern in other places in
YAAC (such as where the bearing and speed of an APRS station that does not report course and speed is inferred).
Let me know if this fixes your problem. I hope it isn't that you folks Down Under use a different standard for ADSB than we Yankees do.

Re: My Brain is about to Explode
Re: location of YAAC configuration: Since you are using a Linux operating system, the Java Preferences backing store is in a subdirectory of your home directory, .java/.userPrefs/org/ka2ddo/yaac . In this subdirectory hierarchy is a collection of further subdirectories, all containing prefs.xml files for that sub-node's part of the configuration. The subdirectory (node) names pretty clearly identify what parts of the configuration are in each sub-node's prefs.xml file. YAAC plugins can create additional sub-nodes for their configuration needs. So there is no single "configuration file", and it is not portable to other operating systems (for example, Microsoft Windows stores Java Preferences in the Registry, but still in a suitable sub-node hierarchy). So don't try and back it up and restore it to a different system to make a duplicate system (expecting exactly the same hardware interfaces on the same operating system variant and using exactly the same callsign-SSID values). Well, it would work if you intended to restore the existing system to the exact same hardware and O/S types for recovering from a hardware failure, but you can't get a template config to use on a non-identical system. Use the YAAC UI and command-line interfaces for a portable way of replicating a config.
