Displaying NWS messages and lightning strikes

#2710

Is there any way to display NWS weather alerts and lightning strikes on the map? I was able to do it in APRSIS but I can't figure it out with YAAC.

That did the trick! Thank you!

Per chance, did you _drag_ the mouse (move it with a button pressed)? Or did you brush the mouse wheel when you moved it?

The map uses the mouse wheel as a (ridiculously sensitive) alternate zoom control. If you don't like that, you can go to the expert-mode Configuration dialog and disable this feature; look on the Behavior tab.

Similar issues can occur if two fingers simultaneously touch a mousepad or touch screen.

Hope this helps.

Re: Resend of earlier query:

Russ - Thanks for the added clarification on CWOP.? I was certain it was for hams initially,

and I understand the addition of non-ham submitters to CWOP would cause problems

if their weather data was propagated by ham digipeaters.

Yours and Andrew's replies to my query makes the subject crystal clear.

Tnx and 73

Bear in mind that the CWOP network is for weather stations _without_ amateur radio licenses, so they will not be forwarded to the regular APRS-IS network (which could be re-transmitted to RF by transmit-capable I-gates). Note that aprs.fi (which is _not_ the APRS-IS backbone, but merely a client of the backbone) is also a client of the CWOP network and several other non-amateur-radio networks (such as the marine AIS network), which is why aprs.fi can display CWOP stations.

Re: YAAC over IP not showing on map at aprs.is

#2701

Are you sending a position beacon or status message? Where are you saying you are located in your beacon definition? Note that, unless explicitly configured, a status message will _NOT_ report your location, so anyone hearing your status messages will only be able to figure your location by radio direction finding or wild guesses based on what stations are digipeating or 
I-gating you.

I looked at aprs.fi, and I see all your beacons (YAAC, APRSdroid, aprs.fi for iOS) are clumped around the south end of a Greek island.

Note that the APRS-IS backbone will never transmit your own packets back to you, so you will only see your packets if they are sent via RF and are echoed back by a digipeater (I see your YAAC RF packets are being digipeated by SV1EMX-11 before reaching the J41VAA I-gate).

Re: Distance Calculation Issue

#2697

The fact that a locally defined object had the correct distance would seem to imply that there was a data error in your received packet from VK5RR. There's no guarantee the packet had the same bit errors at the I-gate that ported it to the APRS-IS backbone, as opposed to at your RF station.

Did you look at that Object in the Radio View, or in the Station/Object List??

Re: Distance Calculation Issue?

#2695

Greetings.

I'm looking through the code, and can't see anything obvious, other than the first '1' in the distance value is aligned with the left edge of the bearing pointer circle. I'm wondering if the leading text character simply didn't horizontally _fit_ in the panel containing the bearing pointer and the text above and below the pointer.

To check this, if you see VK5RR show up again, could you look for the station entry in the View->Station/Object list table, and see what distance and bearing is displayed there? Note that if the text field in the table begins or ends with "...", it means the table column is too narrow to fit all the characters in the column, so you may have to widen the column by dragging the edge of the column header (just like you would resize a column in Microsoft Excel).

Also, were you seeing any other Australians at the time? If so, were any of their distances truncated?

Let me know what you find.

All:

While monitoring 30M APRS, I noticed a discrepancy in the distance calculated by YAAC between myself and VK5RR. The range should be approximately 10,500 miles, but YAAC showed 1,700 miles. I checked APRS-FI to see if VK5RR's position might be off, but it appeared to be correct. YAAC did show the correct bearing which is 273 degrees.

The distance for all other stations seems fine so not sure why the discrepancy for VK.

Any ideas?

Subject: Re: [yaac-users] objects.pos

According to chatGPT;

This string appears to be an APRS (Automatic Packet Reporting System) location beacon, commonly used in amateur radio for reporting position. Here's how to interpret it:

  1.  *111111z

     *   The * might indicate a comment or other specific data type, depending on the context.
     *   111111 is the timestamp in UTC (Coordinated Universal Time) in the format DDHHMM:
        *   DD = Day of the month (11th day, in this case).
        *   HHMM = Time in hours and minutes (11:11 UTC in this case).
     *   z indicates that the time is in Zulu time, another name for UTC.
  2.  4738.27N

     *   This represents the latitude in degrees and decimal minutes:
        *   47 = 47 degrees.
        *   38.27 = 38.27 minutes.
        *   N = North latitude.

To convert to decimal degrees:
47+38.2760≈47.6378°47+6038.27?≈47.6378°.

  3.  12243.53W

     *   This represents the longitude in degrees and decimal minutes:
        *   122 = 122 degrees.
        *   43.53 = 43.53 minutes.
        *   W = West longitude.

To convert to decimal degrees:
122+43.5360≈122.7255°122+6043.53?≈122.7255°.

  4.  r

     *   This is the symbol indicator that tells what kind of object this is. In APRS, different symbols are used to represent various things, such as cars, planes, or weather stations. The specific meaning of r would depend on the APRS symbol table being used.

Final Interpretation

This beacon is reporting a position:

  *   Latitude: 47.6378° N
  *   Longitude: 122.7255° W
  *   Timestamp: 11:11 UTC on the 11th day of the month.

This location is near Seattle, Washington, USA. If you have further context, such as the type of object being tracked (e.g., a mobile station, weather station, etc.), it could provide additional details.

Like what does this all mean:

I feel like the *111111z is time and equals permanent.

What’s the rest mean if I got that right.

There are 2 ways:

1. Click the Message->Station menu entry.
2. Just type it in at the bottom of the map window.

There are other ways as well if other plugins (such as the smallscreen plugin) are installed.
