Well, to me, aprs.fi is showing VE2EP-1's weather data, but his raw packets do seem to be missing the field that documents the weather station hardware (Peet Bros, Davis, etc.) in the weather sequence. He should configure that on his weather input port in YAAC.

It is strange that his weather station is also configured as a digipeater, because I see YAAC's automatic appending of his supported digipeat aliases after the weather data. Also, when I first logged on to aprs.fi, it was showing his station with the 'X' icon for Xastir (or Unix in general) stations rather than the blue WX circle icon. Was someone jamming him?

I'm wondering how he is not seeing his own packets echoed back by some digipeater, unless there is either collisions from two or more nearby digipeaters (so the echoback of his packets is always destroyed at his listening area), or he has a viewing filter set up on his YAAC instance that is excluding the echoback of his packets.

HI Andrew

I am the "neighbour" that Ian refers to - VA3JLF-1. And my yaac map shows the correct weather for both my and Ian's stations. I understand your explanation of the different paths and so on but why is my station VA3JLF-1 not suffering the same fate as his? Is there some setting in yaac that is causing this? He and I have compared settings, unless we have missed something, they appear to be the same on both systems.

Any help in solving this would be appreciated because we have scratched our collective heads and come up empty.

Ah, you have fallen into the misguided and incorrect assumption that you can use aprs.fi for propagation analysis. You cannot do this, because the APRS-IS explicitly does not report _every_ packet delivered by I-gates to the APRS-IS backbone, but only the _first_ _instance_ of each packet. So only the fastest I-gate on the lowest RF delay path will get credit for forwarding your packets to APRS-IS.

Let us make an entirely hypothetical example, since I don't know all the stations in your vicinity.

Let us assume that an I-gate near VE3UEL is using DireWolf, a software TNC with built-in I-gating capability. As soon as the packet is finished demodulating, DireWolf has the packet on its way to APRS-IS (it doesn't have to send the packet anywhere else first).

Let us also assume that the I-gate near VA3PEC is using a hardware TNC, so after it demodulates the packet, it has to send the packet in KISS mode at 9600 baud (bulked out by asynchronous start and stop bits and framing) to the computer running the I-gate software. Assuming your packets are 70 bytes of address header and payload body (a reasonable size with 2 digipeat aliases, plain ASCII encoding of latitude and longitude and no timestamp, and at least 5 fields of weather parameters), that takes 75 milliseconds just to get the packet out of the TNC and into the attached computer so the I-gate software can start processing it.

By that time, the DireWolf instance has already delivered its copy of the packet to its APRS-IS server.

So the TNC I-gate loses and will not be reported on aprs.fi as sending the packet, even though it heard the packet at the same time as the DireWolf instance did (and that's assuming both digipeaters are retransmitting the packet at the same time, rather than one waiting for another local station to shut up, or one improperly configured to do random delay of packet transmission instead of as soon as the channel is clear).

The only way you can tell if a digipeater has digipeated your packet is to listen to the digipeater's RF transmissions on RF. And you can't tell if a digipeater sent it if another digipeater collides with its transmission, causing the packet to be lost in interference.

Hope this helps.

Well, the my last 34 beacons were digipeated by ve3uel according to aprs.fi, which is approx. 50 kms from here and one from ve3pec which is approx.. 10 kms away. Va3pec is not a particularly busy digipeater. So my conclusion is that I am being “Ignored”.
Interestingly though I can see both va3pec and ve3uel in the raw packets list in YAAC., plus many other stations being didipeated by both repeaters but only mine nine along with others by ve3uel

The first question I would ask is "How do you know the nearest digipeater is ignoring your signal?"

What evidence do you have to support that statement?

RF only. The nearest digipeater ignores my signal but a distant one picks it up and sends it to an igate. Actually there are three digis quite close and they all ignore me.

Are you using RF on your station or just an Internet connection? Bear in mind that YAAC only reports _received_ station information, and APRS-IS never sends your own station's packets back to your own station, whereas local digipeaters will bounce back RF packets your station has transmitted.

All is well in the outside world. Station and weather seen on YAAC map of my near neighbour. APRS.FI<> is also correct.
My local map is showing all the stations reporting weather in my vicinity except my own. Just the weather symbol. The beacon doesn’t update it.

Anyone see a similar problem

OK, never mind! I found that the YAAC window was moved up out of range of the display.

Fixed it!

Oh! And I can't grab the dialog box by the title bar and move the window around either.

I tried to minimize the YAAC window on my Pi 400 and realized the doo-hickies for minimize, restore and close normally at the top right of window dialog boxes were missing.

It appears I can use the context menu on the task bar to do those things, but I thought it odd nonetheless.

The default beacon is per-profile, so if you change profiles, you will get a different default beacon.

Yes the profile is specified using the -profile command and it has been working fine. Is the default beacon unique to a specific profile's configuration, or if I change the default beacon will it also affect the default beacon in other profiles?

Were you using the -profile command-line option to specify different configuration profiles? If so, you have to specify the option every time you want to use a non-default profile, otherwise YAAC will use the unnamed default profile.

Also, within a profile, you will always have the default beacon, and it appears first in the list of beacons defined for a profile. Click on the drop-down of beacon names, and you will see any other named beacons you have saved in that profile.

Hope this helps.

I have a Home and Mobile profile with different settings on my portable TNCPi with display unit. For my mobile profile I created a Mobile beacon configuration which I saved. I was hoping that when I re-opend the Mobile profile the Beacon would be set to Mobile but it is back to default. Is there a way to keep a specific beacon configuration associated with a profile so that I don't have to go in and select it? 1.0-beta 196
