Some great ducting today and this evening, PBN188 picked up at 485nm or 898km (the plot way east of NATLI) heading for Auckland probably.

This website is good for Troppo Ducting predictions...

I was looking at this link earlier this evening Stephen, and Saturday is looking pretty good, with some Intense and Very Intense to my north east.

Just checked the plots again, and there was another one at 496nm or 918km.

According to the Tropospheric Ducting forecast, Saturday should be very good, and a quick check this evening showed that things are already improving from the normal conditions of the past few days. PBN79 from Brisbane to Auckland (the small white circle at 60degrees) was showing up at 456.7nm (845.8km).

Tropospheric Ducting forecast for Saturday late afternoon and evening from William Hepburn (http://www.dxinfocentre.com/tropo_aus.html).

It will be Strong to Intense out to the Northeast from Sydney.

I've seen ducts open up all the way to New Zealand. When this happened you could get TVNZ from Auckland on VHF.

Some good ducting again today, out to 480nm.

Not a lot of longer range ducting pickups today, however there was one nice one at 513.4nm (951.4Km out in the red circle). From the Hepburn charts, Saturday evening should be really good - looking for that elusive 1000Km.

The flight looks to be :-

Grahame,
I have been wondering how you get those markers you have on your plane plotter map, such as DRUMO, NATLI etc?

Those are waypoints. They are in a gpx file in the planeplotter chart files folder.

Thanks Mike.
I've clicked on Options, Waypoint File, and clicked on every txt file listed, but nothing shows up on the east coast of Australia.
Am I doing something wrong or do I have to get the information from somewhere else to to load to the chart files folder?

Actually, looking at Plane Plotter help file, the Waypoint File option, is only used for ACARS operation.

I've clicked on Options, Chart, GPX Overlay, and have worked out how to show the overlays from there. There one which Grahame has doesnt seem to be there, but I am just creating my own. Thanks for the assistance.

Looks like the default waypoints.gpx file in planeplotter only has UK Waypoints.

Where are you located?

No idea when I got my spikes in distances, sadly would need to manually look at each day for the start/end point. Red rings are 100km and the orange 50km.

Historically (2016 at some time, one of many I could find (https://c2.staticflickr.com/2/1594/24220654200_87dbaf03eb_o.png)), I have had better range during DX events with range going all the way to Port Phillip Bay, Campbelltown, Dubbo, Cobar, Robinvale (near Mildura) and around 250km off the South Coast, but was history was lost when I had to reinstall the software. My antenna setup is well over due for maintenance.

Hi Robert,
Im out near The Rock.
Is your map from Virtual Radar software? thats a good coverage plot, there was some very good conditions on Tuesday, though I didn't see much increase in range here, but I know some others did.

Grahame Hutchison

You have a nice even 360 Degrees Range Plot there Robert (Antenna working very well) - Here is my latest Range Plot which runs to around 250nm over land, but over 600nm out to sea (more than half way to New Zealand at its best).

Looks amazing Grahame. Looks like around 700 nm to me. 1200 km or so.

Grahame Hutchison

Correct Leigh, the best pickup has been 759.4nm for NZ191 Auckland-Adelaide at Bearing 116.5 Degrees and 38,000ft.

I was lucky enough to get this one and numerous others yesterday morning 05.03.18, but this was about as far as I saw on the map, 808 km NW of Adelaide. On Sunday I made a few adjustments to my antenna set up. Worked out well.
Attachment is probably a bit blury sorry.

Ideally for a given antenna setup, your best reception results will occur in the evening during anticyclonic conditions (stable high pressure) where tropospheric ducting occurs.

In terms of the “waypoints”, they are usually mandatory reporting points, where an aircraft must estimate an ETA and report at that spot, useful when there is no radar coverage or there has been a failure and procedural control is in place. Not sure how much procedural control is done these days with ADSB and other technologies augmenting radar.

Hi Robert,

I'm on the floodplain (so in the valley) and can pick-up aircraft on the taxiway from the disused ATC tower and runway for most aircraft (light aircraft I lose just before the runway, lower power and smaller size).

Yes, using VRS as Plane Plotter has been a pain to use (drops all streams for no reason at all).

Sadly my FR24 box changed IP (due to the router having changes made due to NBN issues) while I was out of town, so it didn't log from Friday evening though til Sunday evening. My RPi did log but range with it on a home built antenna isn't great.

Thanks Mark for the info. Not sure if your aware but the occurrence of tropospheric ducting will depend upon location, time of year and current weather events.

For dry inland areas like Wagga, the air becomes really depleted of humidity in the afternoons during summer and thus the afternoons and evenings are the worst time of day. Early morning is usually the best as the humidity builds up again during the night, only to begin the depletion process again as the sun comes up and the day progresses.

In contrast, areas closer to the coast and oceans have more moisture at all times of the day and evenings may well be better depending on the weather systems.

For inland areas in the south east, west of the great divide, during winter, evenings can often be the better time and mornings not so good as there is a lot more humid air about in those areas at that time of year.

Lots of variables, very interesting to observe.

G'day Robert,
Thanks for the info.
That would be good fun to be near the local airport.
I often wondered about the TX power level differences between the plane sizes.
Yes I hear what your saying about the flood plain. Its painful to try and get decent reception out of Wagga itself as there are low level hills all around. Your VRS map was impressive though, all things considered.

Had some enhanced conditions this morning to the north west, from just SW of Wagga. Furthest ive seen so far on this NW heading. The first spot was at 716 km but I wasnt quick enough to get a screen shot at that distance, this one is 705 km. There was a few on this path heading to Sydney which I received in the 600 km range.

Yesterday morning 12th March there was a rather big tropo opening down south of Australia, west of the great divide.
Here are some of my screen captures, furthest signal decoded was at 1134 km from my location near Wagga, and to the SW of Port Lincoln SA.

Been missing most of the DX'ing. FR24 box has been dropping it's connection and the VRS doesn't re-try for a connection, along with me possibly putting on a limitation on ignoring anything more than 500km (have to double check)!

Leigh R
15th March 2018, 08:41 AM
Robert,
Yeh you better increase that range limit.
You could set up Team Viewer if your not near the PC and access it remotely if its possible to then tell it to reconnect.

Robert.M
26th March 2018, 09:10 PM
I would but have my network locked down. Also a black out can knock out the computer operating VRS and it (the computer) doesn't auto boot when the power returns (has been an issue for awhile but haven't been able to fix it)
