Review: Two ACARS Log Analyzers for Windows

(This was originally part 1 of the post below, but I split it off to make the posts shorter.)

Along with the Dynamic Data Exchange path described in the post just below, some listeners are adding ACARS log analyzers to crunch the data from acarsd.

What you do here is run acarsd with yet another DDE server active, and add yet another client application! That's five simultaneously running programs, for those with the courage to keep count, and yes, you still have to start them in order of the data flow. It all works, at least on my hot dual-core XP Professional system with 2 gig of RAM. All these ones and zeroes churn around inside the machine. Messages appear on screens at various intervals, and ultimately get written to the analyzer database.

I'm not sure these analyzers are worth it for HF, though. I tried two of them. Some people love each of them, so they obviously work well enough to fill their needs. Once again, the price is right, as in free. However, I'm more oriented to DXing and finding new catches than plane spotting, and I'm not sure either program added that much more to acarsd to justify the increased level of complexity.

For a start, neither program seemed to contain an easy way to display the ICAO 24-bit hex addresses, though I understand from various Internet chatter that this may be added soon. My real problems seemed to come from both programs' heavy reliance on various data handling features in the Windows operating system itself. Those of us who have spent years fighting with these know what a mess THAT can create!

After the glowing review that another MT column gave the first one I tried, known as ACARS Log Analyser (British spelling), I couldn't wait to get it going. For whatever reason, though, my results weren't as good as his.

It's possible that my problems were caused by Windows DLL conflicts. It's fine for radio freeware to want to replace multiple shared DLLs with older ones. However, it's also my policy not to let these installers do so, because the resulting unpredictable problems with other, more important (or expensive!) apps can really be a mess.

Perhaps this is why the Log Analyser was so fussy, not to mention prone to all manner of arcane error messages, some of which crashed the program. After working through several truly bizarre logic bombs, I finally got the DDE working, sort of.

I never did get my older logs to import. Only one format worked at all, and this one corrupted all the records to have dates 20 years from now. Since I doubt even the NRD-545 can hear into the future, I finally put this program out of its misery with a full uninstall. Since this is Windows, there were a few harmless dregs left in the Registry, but nothing too critical.

Next up, I tried Acars Analyser (Australian spelling). It's right here. This one is a bit slicker, with pretty little icons and an interface generally more to my personal liking. Even better, its installer didn't ask to change any DLLs at all.

I also like the way the software is structured into two parts. One of these is a DDE client, which (like acarsds) connects to any number of programs and then sits happily in the background. The setup screen for this client is accessible, and comprehensive. The other part is the actual analyzer. It works with an external database using Jet (the MS data engine, not an aircraft type). Many items are stored, and these can be massaged in a truly impressive number of ways.

Unfortunately, that's all I can really say about this program. It never got a fair trial on my machine. It, too, seemed fussy. I never got past the initial stages of file not found errors and an occasional hang when I tried to access the database.

This might have been my fault. I became confused during the installation, and later I was able to find multiple database file paths in the Registry. It's possible the code became confused too. Also, according to the programmer, the public databases that make several of the better features work suddenly stopped being maintained, crippling these until an alternative is found.

At this point, I decided that I really wasn't going to use this program very much for what I was doing, and I uninstalled it. The end of this project is at hand, with Posfix and acarsd doing the job just fine. I've come to like these a lot.

Happy buzzing on HF!

Review: Several Windows ACARS Programs

It all started when the hard core HFDL enthusiasts on the Yahoo! group told me that you could connect Charles Brain's great PC-HFDL program to other data processing applications via Windows DDE.

If this last sentence is total gobbledygook to you, well it would also have been to me about three months ago. I would imagine one of the fancy (and pricey) high-end ACARS packages would do all this stuff with a fraction of the geeking, but fortunately I like to geek. After all, this is amateur radio.

Acarsd and PC-HFDL

I'd read good things about a free program suite called acarsd. You can download it at acarsd.org. It's a rather comprehensive ACARS package, with all the features that the hard core aviation geeks have come to expect, such as real-time fetching of aircraft data, including photos, from plane spotting sites.

Acarsd contains a decoder, but for HF I really wanted to continue using PC-HFDL for the transport layer. You need the commercial PC-HFDL version to do DDE. It's a nice little program, especially in its newest 2.041 beta, which adds some features and generally improves the decode.

Unfortunately, Vista broke it, along with most other shareware/freeware sound card radio decoders. This is a problem since Charles, as of last year at least, didn't have access to a Vista box to develop the fixes. Users of GOOD operating systems, such as Windows XP Pro, will have no problems, though it definitely likes some sound cards more than others.

Getting back to acarsd, it's a remarkable package for the price (free, though donations are encouraged). It also has a Linux version. It is configurable to do just about anything, mostly by manually tweaking the self-documenting .ini file. Other documentation is pretty minimal.

In order to send PC-HFDL decodes to Acarsd, you need the "SkySpy Socket Collector," an accompanying DDE server application which is called acarsds. This program, which is bundled with newer versions of acarsd, works like a charm. Its documentation, though, is extremely out of date.

For example, you are told to download acarsds separately, and install it to its own directory. You don't have to. You are told that you need a specific Visual Basic runtime library. Unless your Windows is ME or older, you almost certainly don't. Finally, you are told not to even bother downloading it if you have Windows XP, because this OS isn't supported by SkySpy. Even if, years later, this is still the case, it's irrelevant for us.

The DDE setup is a complete no-brainer. Soon, you have this neat little server happily passing your ACARS messages to the cool acarsd graphic user interface. Not long after, you notice that many of the interesting HFDL downlinks don't display, because technically they are HFNPDU PERFORMANCE messages, not ACARS. Too bad, because most of these have the position of the aircraft.

POSFIX

Fear not. This is where POSFIX comes in. It's also free, and you get it right here. The latest version in January 2008 is 2.34, though a newer version that adds SBS and some other features is in beta. Posfix is also minimally documented at best, though the help does tell you how to make the program work.

What Posfix does is to reformat the HFDL positions into pseudo-ACARS messages which get sent to acarsd and displayed. Acarsd gets a lot more interesting, and your logs get bigger faster, though you also get a lot of NO-REG for missing registration numbers.

What you do is to set Posfix as a DDE client for PC-HFDL, and then set acarsds as a client for Posfix. This results in the following DDE path:

PC-HFDL > Posfix > acarsds > acarsd.

Also, things crash if you don't start servers first and clients second. This means you start PC-HFDL, get it going on a frequency, then work left to right along the path shown above. Posfix connects to PC-HFDL, and messages start appearing in its window. Acarsds connects to Posfix, and messages appear there. Acarsd connects to acarsds, and messages appear there, in its slick formatting, and including the position checks. Also you can plot with Posfix, though unless you're monitoring the North Atlantic run you'll want to make some more maps. Fortunately, this is stupidly easy.

This took me a couple hours of tweaking to get right, but the results are worth it.

UPDATE: This post has been split into two parts to decrease its length. The second part should be above.

V2x Is Again Nine-Less

Haven't heard any at all since that one transmission.

Oh, well.

Meanwhile the digital SK01 transmissions continue.

HAARP HF Earth-Moon-Earth Echoes!

The HAARP project in Alaska has been transmitting 3.9 megawatt carrier in the direction of the moon, so that a receiving site in another location can take data on the lunar surface (and just below) by analyzing the echoes received.

HF lunar echoes are not the kind of thing one hears every day. THIS is DX.

On the second night of the test, January 20 UTC, echoes were received here in California on the second frequency (7407.5 kHz CW) for a considerable period around 0740-0800 UTC. Here is a typical spectrogram as received on a PAR End-Fedz wire and plotted with Spectrum Lab:



The HAARP carrier is being keyed down for 2 seconds (and received here via the ionosphere) and then a 3-second silence is provided to listen for the delayed (and slightly Doppler shifted, apparently) lunar echoes. The HAARP (ionosphere) reception is at 40, 45, 50, 55, and 00 sec. The echoes are clearly seen in between, down about 10-15 dB.


More on this EME experiment is here.

V02a Has 9's!

Yesterday I noted that the Cuban voice numbers transmissions (V02a, V02c) have recently had very few, if any, appearances of the figure "9" (nueve) in the Spanish messages.

This was true until this morning.

17435 is as loud as ever at 1700, and has plenty of 9's, as if a software issue had been addressed.

Do they read this stuff?

The Woodpecker Is Dead, But Enter the Dragon

China's HF "Dragon" over-the-horizon backscatter (OTH-B) radar may be getting more troublesome for other radio services as that country continues to modernize and build out its military capability. This radar system transmits complex tone bursts spread out over several kilohertz. It has caused an enormous problem for Asian weak signal CW operations in the 40 meter amateur band, though I've never heard it here.

Developing...

SK01 Has 9's

As many people have noticed, the number "9" is rarely (if ever) heard in the V2a Cuban voice numbers broadcasts. If the encryption is random, it seems odd that there wouldn't be any 9s. Why would this figure be excluded? Why is it present in filenames/headers for SK01 (the digital file transfers)?

One more mystery wrapped in a riddle shrouded in an enigma, no pun intended. (After all the German ENIGMA code had 9s.)

Is Cuba Going RDFT?

Probably not, but it's sure increasing, in a manner suggesting it may now be operational. From Jon in FL, as posted to Spooks, ENIGMA, and everywhere else:

NASA ANNOUNCES SPACE SHUTTLE LAUNCH TARGETS

HOUSTON - NASA Friday announced Feb. 7 as the target launch date for shuttle Atlantis' STS-122 mission to the International Space Station and mid-March for the launch of Endeavour on STS-123. Liftoff of Atlantis from NASA's Kennedy Space Center, Fla., will be at 2:47 p.m. EST.

A decision by the Russian Federal Space Agency to move up its Progress launch from Feb. 7 to Feb. 5 enables both STS-122 and STS-123 to launch before the next Russian Soyuz mission in early April. This allows astronauts assigned to the space station's Expedition 16 crew to complete the tasks they have trained for, including support of the launch and docking of Jules Verne, the first European Space Agency Automated Transfer Vehicle. Targeting Feb. 7 also allows time to complete modifications to the engine cutoff sensor system that postponed two shuttle launch attempts in December.

Atlantis' main objective during its STS-122 mission to the station is to install and activate the European Space Agency's Columbus laboratory, which will provide scientists around the world the ability to conduct a variety of experiments in life, physical, and materials science, Earth observation and solar physics.

Shuttle Endeavour's STS-123 mission will deliver Kibo, the first section of the Japan Aerospace Exploration Agency's laboratory module, and Dextre, Canada's new robotics system to the space station.

NASA managers will meet in the coming weeks to address the schedule of remaining shuttle flights beyond STS-123.

San Francisco HFDL Back On-Air

If you heard nothing yesterday on any of San Francisco ARINC ground station 01's frequencies, well no one else did either. The timing suggests problems connected to the storm which hit the Sacramento area with flooding and hurricane-force wind gusts.

10081 is operating at full power at present.

Another storm connected situation exists in a small Nevada town east of Reno, where a breach in the levee of a water canal has flooded 600 homes, requiring boat and helicopter rescues.

HFDL System Table 32/ 20 Hex Now In Use

Just when we thought maybe table #31/1F might get us all the way through the winter, ARINC has updated its ground stations to frequency table number 32, or 20 in the hexadecimal notation the HFDL system uses.

According to several posts to the HFDL group on Yahoo, the only change is to fix a frequency error in version 31/1F that had aircraft looking for Shannon on 2988 kHz, while the ground station squittered away all alone on 2998. It seems awfully coincidental that the mistake was corrected right after the frequency anomaly was discovered and discussed on this same group. It would be very cool if this hobby, and not just a coincidence, was indeed the reason ARINC fixed it. Always glad to be of service.

Let's hope that Shannon now gets more activity on those long winter nights.

The new pchfdl.dat file has been posted to this column's web site. It should be the same one as posted to the Yahoo group, and successfully installed here. Rename your old pchfdl.dat and copy this one in its place, then start PC-HFDL and it should show the frequencies instead of just numbers.

We thank the Yahoo group people for being so on top of things.
