Looks like you're good then re: absolute barometric pressure bounds. The US MADIS lower limit is 568 HPa, and the reported average at the top of Mount Kosciuszko is around 880HPa.

Mount Kosciuszko is the tallest mountain peak in mainland Australia at 2,228 meters (7,310 feet) tall. It is located in the state of New South Wales, in the southeastern part of the country.

Mount Ossa has an elevation of 5,305 ft and is the highest mountain in Tasmania.

Also, regarding the green boxes and "tan" text. That actually is probably red text indicating that field looks unreasonable compared either to other nearby weather stations, or against absolute standards defined by the US National Weather Service; for example, there is a broken weather station in my area reporting a barometric pressure of 699.2 HPa when all the surrounding stations are around 1010 HPa, so its pressure value is displayed in red. Sure, air pressure at the top of Mount Everest is only around 330 HPa, but there aren't any mountains nearly that tall in the United States, so the US National Weather Service has a minimum barometric pressure check that is reasonable for anywhere in the US. Do you have mountains in the same elevation class as the Himalayas anywhere in Australia? As in, do I need to adjust the absolute bounds checks for pressure?

Ah, that's interesting. YAAC is not decoding the weather data from VK7DSH-1 because it expects the uncompressed course (wind direction) and speed to begin the weather data, but that station is using compressed position format which includes the course and speed. I will have to fix the recognition of weather data when using compressed position format.

Thank you for finding that bug.

I don't know anything about how YAAC displays weather stations, but I was curious what you mean by VK7DSH-1 having a "message tacked on the end"? I'm not seeing anything out of the ordinary in aprs.fi's raw packet display?

Just one other small issue is the color scheme in Health Monitor, most of the fields have a light green background and with the Tan? colored text it is extremely difficult to read.

Thanks for your efforts.

Hello, Mike.

I'm not sure I quite follow you. Are you referring to the View->Weather Status dialog for your local station? Or the popup window on the map when you click on a station? The latter shows only the weather data fields that particular station has, so it might look different on different stations (ex.: stations with versus without barometric pressure sensors).

Another alternative present in YAAC now is the monitored stations list. If you monitor a station, it goes on a special list with several table views in the View->Health Monitor window. If you are monitoring the weather health of several weather stations, they will be displayed in a consistent tabular view, including indicating what sensors of a station are not consistent with the US NWS MADIS quality checks relative to the other stations.

Hope this helps.

Andrew, KA2DDO

Hello Andrew,
When I click on my weather station icon my weather data is nicely displayed in a window.
How about the same format for weather stations other than my own and to allow each of these to remain open when I select another station to see its information.
Regards,
Mike VK7TM

The BulletinBoard view will display any bulletins that you receive (i.e., someone on your RF channel or within your APRS-IS port filter has to send them).

The retention period for all YAAC displays is configured on the expert-mode Configuration dialog on the General tab. The "Time to keep" is approximately how long a packet will be held in memory by YAAC for display and analysis purposes. The "Maximum age to view" is how old (relative to YAAC's reception time of the packet) a packet can be before it is no longer displayed. It doesn't make sense for view age to be larger than keep time, since anything that isn't kept can't be viewed, but the opposite can be useful when you want to see more current information and less ancient information in the displays.

"Time to keep" can be forced down automatically by YAAC if you are receiving a large amount of traffic relative to the amount of heap memory you are allowing the Java virtual machine to allocate to YAAC. Rather than have YAAC hang or crash due to out-of-memory errors, YAAC will push down the "Time to keep" setting so the next purge of out-of-date packets will hopefully free up more memory.

Hope this helps.

Subject: Re: [yaac-users] APRS-IS Filter

Thank you Andrew. Yes some of that was typo and most was just wrong on my part. I have made some changes so we will see what happens.

A couple more questions.

Is it possible to populate the bulletin board with bln front aprs-is.

When the message page pops up the messages disappear pretty fast. Where do I stet that to stay longer especially messages sent to my call.

Thank you Andrew. Yes some of that was typo and most was just wrong on my part. I have made some changes ?so we will see what happens.?

Soooooooo..

I have to have a little fun here as I am intrigued by this discussion.

If I'm reading this right, we can take a Weather Alert and feed that to APRS via YAAC? If true, I want to learn how......

And I know what's wrong with Dale's configuration. Its that he's a Chiefs fan.. Go Hawks!!!!!!! Hi HI......

73 all of you, thank you all for threads here.

The difference between the APRS-IS port filter and the supplemental Tx I-gate filter is as follows:

The APRS-IS port filter controls what extra comes _into_ YAAC from the APRS-IS backbone. The supplemental Tx I-gate filter specifies what extra will be _forced_ to RF of what was received (assuming you are configured to allow Tx I-gating at all, which is a separate checkbox in the expert-mode configuration dialog). Which means that you can force all you want, but if it doesn't come in, it won't be there to be forced out.

I hope that period after K0FJ* is a typo in writing your email, because it wouldn't match either of the callsigns. I hope you don't have the literal word "filter" in your YAAC filter expressions, because it is automatically injected prior to the expression you specify, and would cause a syntax error in the filter parsers (saying "filter filter m/600 ..."). Also, specifying the NWS stations as NWSGLD isn't going to work; the examples I have seen are messages GLDSVR (for severe weather from GLD). So you might want to just look for senders GLD* and DDR* (since neither of those starts are valid amateur radio callsign prefixes). Other suffixes to those three-letter NWS offices are things like TOR (tornado), SVS (severe weather), FLS (flood), etc.

Also, that is _way_ too much to specify in a supplemental Tx filter, because you won't have enough bandwidth to force all that out to RF. A 600-kilometer radius of traffic shoved onto a 1200-baud channel, when normal RF range maxes out around 100km (unless you have some serious mountain digipeaters) and channel saturation can easily be much smaller than that?

An Object sticks around for 3 retransmission intervals after you kill it, to send "I'm a dead Object" message (so other stations don't have to wait for it to timeout in 80 minutes).

If you delete an Object from the Local Objects table without changing it to killed status first, then the received traffic (from digipeaters) will continue to sit there until your data purging time interval is reached (since you will never receive a "killed Object" report).

Hope this helps.

Subject: [yaac-users] APRS-IS Filter

Back when I was using UI-View I use to gate wx warnings to RF from 2 od my area NWS offices. UI-View had a special area to add stations you wanted to gate. I would put NWSDDC* and NWSGLD* in that list and I would get the warnings. In Yaac I have my APR-IS filter in the port settings to fllter m/600 b/K0FJ*.W0RBO*/NWSDDC*/NWSGLD*/ t/nwt but am getting no alerts. I have the sane in the supplemental TX I-gate filter as well. I havent figured out the differnce between the two.

Also I was testing sending out objects to certain locations. I then went to kill the object but it still shows on my screen although it isnt being sent out anymore? Thanks Dale

You can delete the entire contents of some tables. For example, if you open the View->Local Objects table, you can choose File->Clear Table to delete every local Object.

But there's nothing in-between to delete some but not all local Objects.

Once you have imported a POS file is there a way to un-import it too? I have'nt found a way other than closing YAAC and restarting, or deleting each object individually.
