RELEASE: 08-072

NASA GIVES "GO" FOR SPACE SHUTTLE LAUNCH ON MARCH 11

CAPE CANAVERAL, Fla. - NASA senior managers completed a review Friday of space shuttle Endeavour's readiness for flight and selected March 11 as the official launch date for the STS-123 mission. Commander Dominic Gorie and his six crewmates are scheduled to lift off to the International Space Station at 2:28 a.m. EDT.

During the 16-day mission, the crew will deliver and install the first section of the Japan Aerospace Exploration Agency's Kibo laboratory and the Canadian Space Agency's two-armed robotic system, Dextre. Five spacewalks will be conducted during the flight.

Endeavour's launch date was announced after the conclusion of Friday's Flight Readiness Review. During the two-day meeting, top NASA and contractor managers assessed the risks associated with the mission and determined the shuttle's equipment, support systems and procedures are ready for flight.
Gorie will be joined on STS-123 by Pilot Gregory H. Johnson and Mission Specialists Robert L. Behnken, Mike Foreman, Rick Linnehan, Garrett Reisman and Japanese astronaut Takao Doi. Reisman will remain on the station as a resident crew member, replacing station flight engineer Leopold Eyharts of the European Space Agency, who will return home on Endeavour.

VP6DX: Not Really Ute, But Interesting

The last couple of nights, the gray line has really been blasting in here. For example, the first major ham radio DXpedition of 2008, VP6DX, is right now S6 on 10106 kHz CW into L.A. for the second evening in a row. (Never understimate gray line... It's how I nailed Clipperton on 100 watts to a simple inverted vee...)

VP6DX is on Ducie Island. It's an uninhabited piece of land to the east of Pitcairn Island, the place the Bounty ended up. Any time a place makes Pitcairn look like civilization, you KNOW you are nowhere. He'd actually worked 30 meters out for a time, but now he's running stations again, and actually getting stronger. Come on you guys in SoCal, you've got to have a signal, here's a new one.

More at ARRL.

UPDATE 0321 UTC: VP6DX is also on RTTY, 10148.9 kHz, taking calls down 10. You have to love ham radio.

First STS-122 Landing Opportunity on Wednesday

From NASA Public Office:

NASA managers will evaluate weather conditions at Kennedy before permitting Atlantis to return to Earth. Wednesday landing opportunities at Kennedy are at 9:07 a.m. and 10:42 a.m. EST. There are additional opportunities at 12:12 p.m. and 1:47 p.m. at Edwards Air Force Base, Calif., a backup landing site. The shuttle's other backup site for landing, White Sands Space Harbor, N.M., will not be activated Wednesday.

Press Release: US Coast Guard Continues HF Weather Broadcasts

Press Release

FOR IMMEDIATE RELEASE

US Coast Guard Continues HF Weather Broadcasts

WASHINGTON - Last April the Coast Guard asked for public comment on the need to continue broadcasting high frequency (HF) high seas weather forecasts for single sideband voice, facsimile charts and text messages over radiotelex (e.g. HF NAVTEX). The Coast Guard required public comment because the infrastructure necessary to provide these services had exceeded its life expectancy and significant costs were involved to continue these services.

After reviewing and analyzing the substantial public response that overwhelmingly urged the continuation of these services, the Coast Guard's "business case study" concluded that it was necessary to continue HF weather broadcasts. The business case study, "An Impact Assessment of Discontinuing USCG High-Frequency Radio Broadcasts of NWS Marine Weather Forecasts" is posted at:
http://www.navcen.uscg.gov/marcomms/high_frequency/HF-WX_notice.htm

The study concluded:

"The responding public collectively perceives that the USCG HF broadcasts are essential to their safety. There is no viable alternative to the USCG HF broadcasts because present alternatives are perceived by the public to be out of financial reach. Also, marine weather forecasts available through these alternative sources may not guarantee the same level of accuracy, timeliness, and/or sufficiency as provided by the USCG HF broadcasts."

While the Coast Guard does not have funds necessary to replace all of its HF transmitters, funds are available to replace the 20 transmitters used for weather broadcasts.

The U.S. Coast Guard is a military, maritime, multi-mission service within the
Department of Homeland Security dedicated to protecting the safety and security of America.

The full report is here. It is very comprehensive and informative, and worth the time to get and read it.

Here's more from USCG Navcen:


The Coast Guard's HF infrastructure

The Coast Guard's HF infrastructure consisting of 123 10KW transmitters are no longer supportable. Repair parts are increasingly difficult to find, more expensive, and take can months to obtain. Funds should be available to replace many, but not all of these transmitters. Consequently all but the most essential HF services are or will be terminated. However, due to responsive received from the public and the conclusions of the business case report, the Coast Guard has decided to continue HF broadcasts of high seas weather forecasts and warnings without interruption. Transmitters used for this purpose will be included among those recapitalized.

The Coast Guard uses 20 high power transmitters to broadcast HF weather facsimile, voice and text (SITOR) high seas weather forecasts to mariners. Three additional Navy transmitters are used to broadcast weather information from Guam. The cost to replace one of these transmitters is ~$200K with installation ($4M total for those used for weather broadcasts).

Reliable, high power transmitters are needed to ensure mariners can reliably receive weather information anywhere within the National Weather Service’s area of responsibility.

[Presumably the services to be affected by the phase-out of the other transmitters include those on this list that are not required by GMDSS or other treaties. More when it happens. -Hugh]

USCG Will Not Drop HF!

This news item has been up for over a week on the Mscan Meteo homepage, though I just ran across it today. It's the first news I've seen of the Coast Guard's decision on its HF services. The news, apparently, is good:

7 February 2008

I just received word that thanks to the feedback of the cruising community around the world, the future of HF radio services is saved! The Coast Guard concludes The responding public collectively perceives that the USCG HF broadcasts are essential to their safety. There is no viable alternative to the USCG HF broadcasts because present alternatives are perceived by the public to be out of financial reach. Also, marine weather forecasts available through these alternative sources may not guarantee the same level of accuracy, timeliness, and/or sufficiency as provided by the USCG HF broadcasts.

NASA UPDATES SHUTTLE TARGET LAUNCH DATES

HOUSTON - NASA officials on Thursday revised the target launch dates for space shuttle flights during the second half of 2008. The space shuttle and International Space Station programs agreed to the changes during a meeting at NASA's Johnson Space Center to evaluate options following the STS-122 mission delay.

The next two shuttle flights, STS-123 on Endeavour targeted for March 11 and STS-124 on Discovery targeted for April 24, are being assessed and coordinated with NASA's international partners. Any decision on those launch dates will take place after the current STS-122 mission lands.

Late 2008 shuttle mission target launch dates are: Aug. 28 - Atlantis (STS-125) to service the Hubble Space Telescope Oct. 16 - Endeavour (STS-126) to deliver equipment to the International Space Station Dec. 4 - Discovery (STS-119) to deliver the final set of solar arrays to the station.

Flights beyond 2008 have not been assessed. Both shuttle and station program officials are considering options for scheduling the remainder of the shuttle flights.

STS-122 Update 1725 UTC

The crew has suited up and boarded Atlantis, which has no technical issues that would prevent launch. However, weather is now up to a 70% of violating launch criteria due to a persistent cold front.

Larry Van Horn has updated MT's NASA content. See his posting to his MT Milcom Blog.

STS-122 Will Try Again Tomorrow

The oft-postponed launch of the STS-122 shuttle mission to the International Space Station is on for Thursday, February 7, at 2:45 PM Eastern (1945 UTC). An issue with a bent radiator hose has been sufficiently resolved to allow a safe flight.

Booster Recovery Vessels are currently deploying downrange.

Weather at Cape Canaveral has a 40% chance of preventing launch.

SAQ To Transmit on 17.2 kHz Wednesday

SAQ, Grimeton Radio in Sweden, is planning a test transmission at 1000 UTC on Wednesday, February 6. The 1-hour broadcast will be made with a 200 kW Alexanderson alternator, basically a large electric generator which produces RF instead of low frequency AC. The frequency is 17.2 kilohertz. Not megahertz, kilohertz. That's low.

This is a radio museum with an original, Marconi-era, maritime coastal station in operating condition. The antenna is enormous. This transmitter is audible worldwide with the right equipment and low noise conditions.

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.
