HFDL System Table #48/ 30 Now Current
Yesterday, a discussion on the HFDL Yahoo group produced the intelligence that the frequencies were being changed in bunches. As a result, it was predicted that ARINC would soon change the system table again.
They did.
You know the drill. Fire up PC-HFDL right now, put it on a loud ground station, and leave it there until the system table is sent to an aircraft. It is done so in a special message type, and in 5 or 6 data packets. It is essential to receive all of these. After this happens, PC-HFDL will magically turn the numbers in the squitters back into frequencies.
The alternative is to get the new PCHFDL.DAT file online. An earlier post tells how to do this. Of course, since #47 has now gone the way of several others in the past weeks, that file has been removed from this column's web site. #48 will be posted whenever I get one that works.

US EAS Nationwide Test November 9
Release from US Government:
First Nationwide Test of the Emergency Alert System November 9 at 2pm EST
As part of their ongoing efforts to keep our country and communities safe during emergencies, the Federal Communications Commission and Federal Emergency Management Agency will conduct the first nationwide test of the Emergency Alert System (EAS). The EAS test plays a key role in ensuring the nation is prepared for all hazards, and that the U.S. public can receive critical and vital information, should it ever be needed. The first nationwide test will be conducted Wednesday, November 9 at 2 p.m. EDT. This test may last 30 seconds, and will be transmitted via television and radio stations within the U.S., including Alaska, Hawaii, the territories of Puerto Rico, the U.S. Virgin Islands, and American Samoa. Similar to local emergency alert system tests, an audio message will interrupt television and radio programming indicating: "This is a test." When the test is over, regular programming will resume. For more information about the nationwide Emergency Alert System test, please visit www.FEMA.gov and www.FCC.gov. On November 9 at 2 p.m. EDT, please remember: Don’t stress; it’s only a test.

PCHFDL.DAT File for System Table #47
This file has been used on this computer to successfully update two different versions of PC-HFDL to System Table #47. The numbers changed to frequencies on both.
I make no other guarantees, because it has not been tested on anyone else's machine. Use at your own risk. It won't hurt your computer, but it might not update PC-HFDL. It should be downloaded as a binary file, and saved anywhere convenient.
In order to use it, first close PC-HFDL. Find the PC-HFDL program directory, go to the folder named "configs," and rename the existing PCHFDL.DAT to something else. Copy this new one in, and rename it PCHFDL.DAT. Start PC-HFDL and pray. If frequencies appear instead of numbers, it worked.
If it didn't work, close PC-HFDL again, delete PCHFDL.DAT, and rename the old one back to that name. Then start PC-HFDL back up.

HFDL System Table Now at #47!
Yes, that's right. Before I was able to post the new PCHFDL.DAT file for ARINC HFDL System Table #43, they put out another one... and another one... and another one... (total is five in about a week).
Obviously, there has not been an opportunity to catch up, and so the file will not be uploaded until this settles down. Meanwhile, leave PC-HFDL going on a strong ground station all day, until it sends the table out to somebody. The program will then update itself, and frequencies will replace the numbers.
Also, the changes in all five tables have been very minor. One can still use old lists and spreadsheets to look up freqs manually. A hassle, yes, but it works. Keep in mind that freqs are numbered from the highest down. Yes, that's right. San Francisco is using 21943 (F-1) right now. Gotta love solar peaks.

HFDL System Table #43 / 0x002B Is Now Current!
After a long interval with no changes, Aeronautical Radio, Inc (ARINC) has revised the system table used in its High-Frequency Data Link (HFDL) network.
Two updates, numbers 42 and 43, were issued in the space of about one day. Number 43 (2B in hex) is still current at this time.
The system table is a lookup database of all frequencies used by HFDL stations. For our use, it is essential in order to change the numbers passed in HFDL "squitters" to the frequencies in use at a given time. One can look this up manually on a text file or spreadsheet of the system table, but it is far quicker to configure software to do it automatically.
In the case of the most popular program, PC-HFDL, this can be done in two ways. The first is to get lucky, and have PC-HFDL open when the system passes the new frequencies to aircraft. This works for the first few days after a change, before the information finally propagates to all users.
The second, and most practical, procedure is to replace the old pchfdl.dat file in the program's runtime directory. This is done by obtaining the new file from someone who has made the update, usually from web sites or links posted to mailing lists. Then close PC-HFDL if it's open. Find the right directory, rename the existing file to oldpchfdl.dat, and copy in the new one as pchfdl.dat. Then restart PC-HFDL and see if the numbers have changed back to freqs.
The structure of pchfdl.dat is completely bizarre, containing incomprehensible snippets of HFDL decodes. However, it works - most of the time.
The new file will be added to this column's web site as soon as I can obtain and test it. This will probably happen around Thursday. Tomorrow, I'll be on an airplane myself.

Interesting Document on USAF HF-GCS Evolution
This link came by way of UDXF.
It's for a .pdf file showing what looks like a PowerPoint presentation regarding the US Air Force's communications on its High Frequency Global Communications System (HF-GCS). The presentation was made by Rockwell/ Collins for a 2010 conference.
Much of the content is maps and charts, and it is best to get this file and look at it.
But here are some interesting facts about the HF-GCS:
1. "F.k.a. SCOPE Command." I take this to mean the SCOPE Command program was indeed an upgrade in HF-GCS, not a separate radio network. [SCOPE was an acronym for System Capable Of Planned Expansion -Hugh.]
2. 13 4 kW ground stations worldwide, with separate tx/rx sites.
3. 2 central control points: NCS-East at Andrews AFB, NCS-West at Grand Forks AFB, ND (under development). [????? GFAFB is currently the 319th Air Base Wing, and is being converted to Global Hawk surveillance drones. -Hugh]
4. The lead command is now the Air Force Space Command. [Again, ?????]
5.The document still shows McLellan (near Sacramento, CA) as "West Coast," even though it does ID as "McLellan." The station in the Falklands is listed as "South Atlantic (UK Station)," and it does not show on the coverage map. It appears to remote to Croughton.
6. Mission list still includes the functions of the previous Mystic Star and SITFAA. Newer capabilities are shown as Link-11 for the US Navy, and support of both test ranges for the Space Command.
7. Circuits between control points and stations are apparently migrating to voice/ audio/ data over IP.
8. It appears that the long range plan includes digital voice and a replacement for ANDVT which would allow end-to-end encryption from telephone to radio back to telephone using a single system.

Solar Observations are Changing Our Vision
This is an exciting time for people who follow solar-terrestrial phenomena. New spacecraft have joined the existing SOHO to give images and insights that were unimaginable even a year ago.
The sun turns out to be an even more interesting place than we knew it was already. Flares are long duration events, not simple explosions. CMEs can generate incredible lacy patterns. They can also now be observed from afar, showing exactly how they reach and engulf the Earth. Sunspots can now be observed while still deep inside the sun, before they reach the surface.
In the short term, CMEs and a coronal hole bode ill for stable HF propagation starting sometime tomorrow, but at least with the equinox coming they'll undoubtedly be great for aurora watchers. Today, though, HF propagation continues to be the best I've heard it in years.

CFH Back To STANAG 4285
CFH, the Canadian Forces Halifax station in Nova Scotia, has switched back to STANAG 4285 (again) on September 1. Some might remember that it briefly tested this mode before going back to RTTY. Well, now it's gone back to STANAG. Parameters appear to be 75 baud, long interleave, ITA2 alphabet, 5 data bits and either no or one stop bit(s). Channel center is 1800 Hz so best decode on my receiver in USB mode is at -1.8 kHz.
The traffic is still an idler with the NAWS DE CFH ZKR ... AR marker every 30 seconds.
As long as we're discussing STANAG 4285, the highly regarded Sigmira decoding program for Windows and Linux has had that same problem with its features.dat file again. Apparently, this file becomes obsolete periodically and has to be replaced, but the program lacks an update function to do this. At this point, the button for STANAG 4285 does not work, and repeated clicking crashes the program.
This can be quickly resolved by downloading the new features.dat to your run directory for Sigmira to replace the existing one. The download is at the programmer's web site.
