FCC to Drop Morse Testing for All Amateur License Classes
In an historic move, the FCC has acted to drop the Morse code requirement for all Amateur Radio license classes. The Commission adopted the long-awaited Report and Order (R&O) in WT Docket 05-235, the "Morse code" proceeding, and released it December 19.
The effective date of the FCC's R&O will be 30 days after publication in the Federal Register - most likely in February.
Currently, Amateur Radio applicants must pass a 5 WPM Morse code test to operate on HF. The FCC's action will eliminate that requirement all around.
Changes to AO-51 CTCSS Access Tone
This week Drew Glasbrenner KO4MA, AMSAT-NA VP Operations reported that the
CTCSS 67 Hz subaudible tone used on AO-51's uplink to enable the FM transponder has been turned off
. Carrier access is all that is re- quired to access this satellite.

Yaesu CAT cable
If you would like to use a benefits that offers computer controlled RIG you need to use a CAT interface between PC and RIG. I have build few simple CAT cable for me and my friends for Yaesu FT-857.
The CAT cable is based on IC MAX232. It’s real simple circuit, works fine, but be careful – wrong voltages on RxD and TxD might damage the CPU in transceiver.

The Geminids 2007
This is one of the best meteor showers of the year and never seems to disappoint observers. Geminid's activity can be seen on
December 7th till 17th 2006
. Results from recent years have shown the peak
ZHR to be over 100 and to remain above 70 per hour for about 24 hours
. The shower is typically rich in bright meteors, but produces few trained meteors.
The best time for meteor-work shall be on
2006 December 14th, within 02 to 11 UT for Europeans
. Please do remember that the shower is very useful for side- and backscatter test (best radiant-times 23 to 03UT) and the shower will have a break between 11 to 17 UT (radiant under horizon in middle Europe).

HamRadio DeLuxe eliminates Doppler effect
Sattelite operation is requiring a lot of hands. If you would like to have a good signal on the uplink and downlink you need to:
rotate antennas in azimuth
elevating antennas
tune RX (TX) downlink
tune TX (RX) uplink
speak into the microphone
log the QSO
LEO FM satellites like SO-50 and AO-51 have an uplink in 2m band. Doppler effect is smaller than on 70cm band. It’s enough to tune the transmitter on uplink frequency. But on 70cm band is Doppler effect three times bigger and it’s required to tune receiver. FM modulation is readable also by 1 or 2 kHz inaccurancy but it’s still problem. There is very nice solution called Satellite Tracking in HamRadio Deluxe program.

ICOM handheld radio programmer
We have build a simple programmer for ICOM IC F-11 handheld radio. It’s simply looked VHF easy to use handheld radio that could be used also in radioamateur bands. This is a military spec. rugged radio that can take abuse and keep working. It has only few buttons and controls without any LCD display – setup is done by computer.
My friend bought one on the rally and wan’t to set new frequencies, CTCSS – so we have build a simple programmer that could be used for ICOM handheld radios, not only F11.

Keith Sproul, WU2Z Critically Injured at ABQ Balloon Festival:
One dead, one critically injured after 'Wings of Wind' balloon crashes into powerline near N.M. 528. The two people who were aboard the "Wings of Wind" hot-air balloon when it crashed this morning have been identified by Kathie Leyendecker, a spokeswoman for the Albuquerque International Balloon Fiesta, according to The Associated Press. Killed in the crash was Stephen Lachendro, and the balloon's creator, Keith Sproul, was critically injured in the accident, Leyendecker said. Leyendecker said she did not know where the victims were from, nor who was flying the balloon. The balloon was registered to a New Jersey pilot, she told the AP. Lachendro was found dead at the scene lying on the side of a ditch, Sproul was unconscious and was flown by helicopter to a local hospital, authorities said. A hospital spokesman said Sproul was in critical condition today afternoon, the AP reported.

Spectrum Defense: 'More Work To Do':
Defending and enhancing access to the Amateur Radio spectrum is the primary mission of the ARRL. According to ARRL Chief Executive Officer David Sumner, K1ZZ, the League has not only protected the bands, but has also added several new ones, despite exponential growth in the variety and number of radio frequency devices in the hands of consumers and businesses. "Even our most disappointing defeat -- the loss of the bottom 40 percent of the 220 MHz band some two decades ago -- gave us upgraded status, from shared to exclusive, in the remaining 60 percent of the band," he said.

Living in Monte Carlo
I posted this here: http://www.yachtforums.com/forums/yacht-crews/10048-my-life-monaco.html#post65529 I have memories of my time based in Monte Carlo as a Steward on board Milamba IV, a 108 foot steel displacement Feadship with a very British (Campers and Nicholson refit) style and British crew. In 1979 I had hitch-hiked to the South of France after dreaming of someday working on a [...]
360 Degree Panoramic View
Today, James popped over and helped me shove a 16 foot lightweight pole into the top of the rotator on the tower. I attached a small video camera to the top of the pole. It was quite funny because I couldn’t control the camera from the ground, so holding the pole horizontally at waist height, we [...]
New Winter 2008 CQWW Vertical
When the kids start to play less outside in the winter, I like to experiment with a new vertical each year. This year it’s a 12m spiderbeam vertical fibreglass pole loosely wound with some hard drawn copper wire. A waste pipe supplies the engineering for the radials with the SG230 doing the matching. This allows [...]
