Second New US Coastal CW Station Licensed
Forward from Dick Dillman, chief operator at KSM, the first new station:
Coordinates given are 47-40-24.0 N, 122-10-11.0 W. Emission is 160HA1A (plain CW Morse wireless telegraphy, 160 Hz bandwidth). Antenna type is not known.
This ought to be good.
A new US class 1A common carrier Morse code coast station has been licensed by the FCC!
As may remembered, I suggested earlier this year that those in the US interested in preserving 500kc for commercial operation should apply for a commercial coast station license - just as we did for KSM.
Two people made applications. One of these has been granted today (9/24).
Station KDR has been licensed to James A. Dalke in Bellevue, WA. OM Dalke is a broadcast engineer who just happens to have a 5kW MF transmitter in the garage so I suspect we will be hearing the signal of KDR before too long. Jim says he as many "interesting plans" for the station.
KDR is licensed for operation on 500kc and 482kc at 5kW.
See all information on the FCC Web site.
One other application is pending. Others have expressed interest in submitting applications.
In my view licensing stations like KDR is the best possible way to preserve 500kc for true commercial operations.

Cuban DIGTRX Numbers 9/13/07
The Cuban numbers stations, always good for a surprise, are at it again.
On September 10, Tom Sevart heard a new digital mode (for them) on 17478 kHz USB at 1600 UTC, and again on 17436 kHz USB at 1700. This is an 8-tone modulation mode with distinctive beginning and ending signals. It was quickly identified by Tom and others as Redundant Digital File Transfer (RDFT), a mode with several submodes of varying transfer speeds. It's used by hams for transferring files, usually slow scan TV (SSTV) pictures. We've written about this before.
Today, September 13, Tom and I both heard transmissions at 1700 on 17436. They were in RDFT and another digital file transfer mode called HamDRM, an amateur version of the Digital Radio Mondial broadcast standard. The program in use identified itself as DIGTRX version 3.11, a free download available on all the usual ham radio sites.
The sending station ID in the DRM transmission was RAD01. The file being transferred was called nen12.txt. Its contents are a standard V02a/M08a three-message encrypted whatever, but without the formatting into 5-figure groups. We thank Tom for sharing his decode with the Internet.
It is interesting to speculate on whether RAD01 and nenxx.txt are internal names used in the Cuban numbers operation, or just special test names. Probably ultimately futile, but interesting.

NWS TPC/NATIONAL HURRICANE CENTER MIAMI FL EP112007
200 PM PDT MON SEP 03 2007
WHILE HENRIETTE'S SATELLITE APPEARANCE HAS IMPROVED DURING THE DAY...AN AIR FORCE HURRICANE HUNTER AIRCRAFT WAS UNABLE TO FIND HURRICANE FORCE WINDS. THE INITIAL INTENSITY REMAINS 60 KT BASED ON A PEAK SFMR WIND OF 58 KT. THE CYCLONE HAS ANOTHER 24-36 HOURS OVER OPEN WATERS AND THE OFFICIAL FORECAST CALLS FOR HENRIETTE TO BECOME A HURRICANE PRIOR TO REACHING BAJA CALIFORNIA. INTENSITY GUIDANCE HAS BEEN TRENDING WEAKER AND THE OFFICIAL FORECAST IS NUDGED LOWER.
HENRIETTE CONTINUES TO CRAWL ALONG WITH AN INITIAL MOTION ESTIMATE OF 315/05. THE OVERALL FORECAST PHILOSOPHY REMAINS UNCHANGED. THE CYCLONE IS EXPECTED TO GRADUALLY TURN NORTHWARD OVER THE NEXT 2 DAYS IN RESPONSE TO A MID-LATITUDE TROUGH CURRENTLY APPROACHING THE WEST COAST OF THE UNITED STATES. DYNAMICAL MODELS REMAIN REASONABLY CLUSTERED ABOUT A TRACK THAT TAKES THE CYCLONE TOWARD THE SOUTHWESTERN COAST OF BAJA CALIFORNIA IN 36-48 HOURS. DESPITE THE CLUSTERING...DYNAMICAL MODELS HAVE CONSISTENTLY BEEN TOO FAST IN THEIR FORWARD SPEED. BASED ON THIS TENDENCY...THE OFFICIAL FORECAST IS A LITTLE SLOWER THAN THE MODEL CONSENSUS DURING THE FIRST 36 HOURS. ONCE IT CROSSES THE BAJA PENINSULA...HENRIETTE IS EXPECTED TO CONTINUE NORTHWARD OVER THE GULF OF CALIFORNIA...WITH A SECOND LANDFALL OVER THE NORTHWESTERN COAST OF MAINLAND MEXICO IN 48-72 HOURS. DISSIPATION OVER NORTHWESTERN MEXICO IS EXPECTED SHORTLY AFTER LANDFALL. WHILE IT IS DOUBTFUL THAT THE CYCLONE WOULD SURVIVE A TRACK OVER THE HIGH TERRAIN OF NORTHWESTERN MEXICO...SOME OF THE RESIDUAL MOISTURE COULD MOVE INTO THE SOUTHWESTERN UNITED STATES.

THE CYCLONE HAS ANOTHER 24-36 HOURS OVER OPEN WATERS AND THE OFFICIAL FORECAST CALLS FOR HENRIETTE TO BECOME A HURRICANE PRIOR TO REACHING BAJA CALIFORNIA. INTENSITY GUIDANCE HAS BEEN TRENDING WEAKER AND THE OFFICIAL FORECAST IS NUDGED LOWER.
HENRIETTE CONTINUES TO CRAWL ALONG WITH AN INITIAL MOTION ESTIMATE OF 315/05. THE OVERALL FORECAST PHILOSOPHY REMAINS UNCHANGED. THE CYCLONE IS EXPECTED TO GRADUALLY TURN NORTHWARD OVER THE NEXT 2 DAYS IN RESPONSE TO A MID-LATITUDE TROUGH CURRENTLY APPROACHING THE WEST COAST OF THE UNITED STATES. DYNAMICAL MODELS REMAIN REASONABLY CLUSTERED ABOUT A TRACK THAT TAKES THE CYCLONE TOWARD THE SOUTHWESTERN COAST OF BAJA CALIFORNIA IN 36-48 HOURS. DESPITE THE CLUSTERING...DYNAMICAL MODELS HAVE CONSISTENTLY BEEN TOO FAST IN THEIR FORWARD SPEED. BASED ON THIS TENDENCY...THE OFFICIAL FORECAST IS A LITTLE SLOWER THAN THE MODEL CONSENSUS DURING THE FIRST 36 HOURS. ONCE IT CROSSES THE BAJA PENINSULA...HENRIETTE IS EXPECTED TO CONTINUE NORTHWARD OVER THE GULF OF CALIFORNIA...WITH A SECOND LANDFALL OVER THE NORTHWESTERN COAST OF MAINLAND MEXICO IN 48-72 HOURS. DISSIPATION OVER NORTHWESTERN MEXICO IS EXPECTED SHORTLY AFTER LANDFALL. WHILE IT IS DOUBTFUL THAT THE CYCLONE WOULD SURVIVE A TRACK OVER THE HIGH TERRAIN OF NORTHWESTERN MEXICO...SOME OF THE RESIDUAL MOISTURE COULD MOVE INTO THE SOUTHWESTERN UNITED STATES.

KSM RTTY Testing Again Today
From Richard Dillman of MRHS:
Once again this Saturday the KSM Transmitter Department plans to exercise the 12Mc RTTY transmitter beginning at about 2000Z and ending at about 2300Z. Press and weather will be broadcast in Baudot and FEC modes.
The Baudot transmission will be 170cps shift, 45.45 baud. The frequency is 12631.0kc.
The tubes currently in the transmitter limit power output to 2.5kW. Once these are replaced a power output of 4 to 5kW will be used. The antenna is a H over 2.
The transmitter for our 8Mc RTTY frequency is undergoing restoration by the Transmitter Department. Once this transmitter operational both 8Mc and 12Mc will be active each Saturday with press and weather information of interest to the maritime community. The 8Mc frequency is 8433.0kc. A double extended Zepp will be used on this frequency.
KSM will be active on Morse as usual on:
426
500
4350.5
6474.0
8438.3
12993.0
16914.0
K6KPH will guard 7050kc and 14050kc for signal reports, NTS traffic and general calls. Since the above frequencies are in a scanner along with the ship calling frequencies, the best procedure to use when calling K6KPH is the same as that for commercial operations: Keep sending "K6KPH" on the above frequencies (within the limits of FCC identification requirements of course). When your call is heard K6KPH will send "DE" after which you can send your call sign. Sometimes things get busy at the station so I apologize in advance if your call is not immediately answered.
VY 73,
Richard Dillman
Chief Operator, MRHS

Sea to Shining Sea (Henriette in E-Pac, Felix in Atlantic)
Felix has a good chance of taking about the same track as Dean, as a hurricane. Bad news for Belize and the Yucatan. Henriette is still tracking right up the coast, and depending on steering will either make the weather very interesting in Baja and Southern California starting Tuesday or so, or it won't. Recreational boaters in these waters definitely need to watch Henriette.
Both storms will affect Mexico. Mexican military ALE and amateur relief frequencies may light up. It's a good chance to practice your Spanish.

TROPICAL STORM HENRIETTE DISCUSSION NUMBER 8
NWS TPC/NATIONAL HURRICANE CENTER MIAMI FL EP112007
800 AM PDT SAT SEP 01 2007
THE CLOUD PATTERN REMAINS LARGE BUT HAS NOT CHANGED VERY MUCH IN ORGANIZATION AND THE CENTER CONTINUES TO BE DIFFICULT TO LOCATE. DVORAK T-NUMBERS SUGGEST THAT THE INITIAL INTENSITY REMAINS AT 45 KNOTS. THE CIRCULATION IS BEGINNING TO MOVE AWAY FROM LAND AND BOTH SHEAR AND SEA SURFACE TEMPERATURES ARE CONDUCIVE FOR STRENGTHENING. THEREFORE...THE OFFICIAL FORECAST CALLS FOR A GRADUAL INTENSIFICATION AND HENRIETTE IS FORECAST TO BECOME A HURRICANE IN A DAY OR SO.
HENRIETTE HAS BEEN MOVING ON A STEADY WEST-NORTHWEST TRACK OR 295 DEGREES AT 10 KNOTS. THE RIDGE TO THE NORTH IS FORECAST TO EXPAND A LITTLE DURING THE NEXT DAY OR TWO AND THIS PATTERN COULD FORCE THE CYCLONE TO MOVE TEMPORARILY ON MORE WESTERLY TRACK. THEREAFTER...THE RIDGE WEAKENS AND THE FORECAST BECOME HIGHLY UNCERTAIN. ONCE AGAIN A GROUP OF TRACK MODELS BRING THE CYCLONE WELL WEST OF BAJA CALIFORNIA WHERE THE OCEAN IS COOLER RESULTING IN A GRADUAL WEAKENING. ANOTHER GROUP OF MODELS BRINGS HENRIETTE OVER BAJA CALIFORNIA OR EVEN THE GULF OF CORTES WHERE THE WATER IS WARM AND STRENGTHENING COULD CONTINUE. THE OFFICIAL FORECAST OPTED FOR THE FIRST OPTION AND KEEPS HENRIETTE WEST OF BAJA CALIFORNIA AND WEAKENING. THIS IN FACT...SIMILAR TO THE PREVIOUS OFFICIAL FORECAST.

TROPICAL STORM FELIX DISCUSSION NUMBER 4
NWS TPC/NATIONAL HURRICANE CENTER MIAMI FL AL062007
1100 AM EDT SAT SEP 01 2007
RADAR IMAGES FROM MARTINIQUE INDICATED THE CENTER PASSED VERY NEAR GRENADA OVERNIGHT...WITH THE ISLAND OBSERVING 1005 MB BEFORE THE WEATHER STATION STOPPED REPORTING. SINCE THAT TIME...SATELLITE AND RADAR DATA INDICATE THAT FELIX IS FORMING A SMALL INNER CORE WITH TIGHTLY-WOUND BANDS AROUND THE CENTER. IN FACT...AN AIR FORCE PLANE JUST MADE IT TO THE CENTER AND REPORTED FLIGHT LEVEL WINDS OF 69 KT...CORRESPONDING TO ABOUT 55 KT AT THE SURFACE...AND 55 KT WILL BE USED AS THE INITIAL INTENSITY.
ALL ATMOSPHERIC AND OCEANIC PARAMETERS SUPPORT A CONTINUED STRENGTHENING OF THE STORM. WITH SUCH A FAVORABLE ENVIRONMENT...IT IS LIKELY THAT FELIX WILL BECOME A POWERFUL HURRICANE BY THE TIME IT REACHES THE NORTHWESTERN CARIBBEAN SEA. THE GFDL/HWRF ONLY SLOWLY INTENSIFY THE SYSTEM...BUT THE SHIPS/LGEM MODELS SUGGEST THIS STORM COULD BE A MAJOR HURRICANE IN ABOUT 3 DAYS. THE NHC INTENSITY FORECAST GOES WITH THE LATTER SCENARIO AND IS JUST A LITTLE LOWER THAN THE STATISTICAL MODELS FOR THIS FORECAST PACKAGE.
FELIX HAS BEEN MOVING BASICALLY TO WEST FOR THE PAST 6-12 HOURS AND MY INITIAL MOTION ESTIMATE IS 270/16. A STRONG RIDGE IS FORECAST TO STEER THE STORM A LITTLE NORTH OF DUE WESTWARD FOR THE NEXT FEW DAYS. TRACK GUIDANCE IS IN GOOD AGREEMENT ON THIS SCENARIO. BEYOND 3 DAYS...THERE IS A QUESTION OF HOW MUCH RIDGING WILL BE PRESENT IN THE GULF OF MEXICO. A FEW MODELS HAVE ENOUGH OF A WEAKNESS IN THE RIDGE TO FORCE A WEST-NORTHWEST OR NORTHWEST MOTION NEAR THE END OF THE PERIOD. HOWEVER...THE RELIABLE GFS/ECMWF ARE KEEPING A STRONG RIDGE. THE OFFICIAL FORECAST IS A LITTLE SOUTH OF THE PREVIOUS ONE DUE TO THE WESTWARD MOTION EARLY ON...BUT THEN IS VERY CLOSE TO THE PREVIOUS FORECAST BY THE END OF THE PERIOD.
