39th Annual Eastern VHF/UHF/MICROWAVE Conference

Registration is now open for the 39th annual Eastern VHF/UHF
and microwave conference to be held April 26th to the 28th
at the Baymont Inn and Suites in Manchester, Connecticut.
This years program includes numerous talks and presentations
for those who enjoy operating in the world above 50 MHz.
This yearly get together is sponsored by the North East Weak
Signal Group.  More information including registration and
hotel information can be found at

Coalition Pushes FCC to Reclaim at least 120 MHZ of Broadcast Spectrum

The coalition of broadcasters willing to sell spectrum
rights has grown to 39 major market stations.  This
according to comments filed to the FCC by the Expanding
Opportunities for Broadcasters Coalition.  The trade group
also wants the regulatory agency to make the auction as
attractive as possible by not limiting wireless bidders or
which stations can share spectrum.

The coalition was formed because the principal broadcast
trade association, the National Association of Broadcasters,
is focusing on making sure the auctions hold harmless
broadcasters who are not selling and want to remain in the
business.  The coalition members don't have to identify
themselves publicly because of the obvious competitive and
operational issues related to publicizing their willingness
to sell.  However they are reportedly pushing the FCC to
reclaim at least 120 MHz of spectrum.

The deadline for comments on the FCC's framework for
broadcast incentive auctions was  January 25th.  Reply
comments are due in March.

Stealth ST-940B Mobile HF NVIS Magnetic Loop Antenna

The Stealth ST-940B Mobile HF NVIS Magnetic Loop Antenna has been developed to address the emerging need to reduce the visibility of vehicles fitted with traditional HF antenna systems. Earlier, the presence of large HF Whip or auto tune vehicular antenna used to make vehicles an easy target But, the unique design of the ST-940B provides for a hidden, almost undetectable presence of en efficient antenna system on the vehicle, which is camouflaged by shaping it as a regular luggage roof rack.
The highly efficient auto tune antenna radiates with an almost vertical take-off angle. It provides reliable communication within distances that are traditionally affected by skip zones created by the radiation pattern of non-NVIS antennas.
A closed H/Q loop circuitry ensures significant increase in transmitting end receiving power as well as reception immunity to ignition and industrial noise. Compared with the traditional whip-type vehicle antennas, the ST-940B gives an additional 9dB of omni-directional gain, even in regions with poor soil conductivity. As a result, the overall performance of the entire vehicular HF installation is now much higher than other vehicle antenna systems.
The NVIS Mobile loop ST-940B antenna is skillfully modeled with extensive use of NEC CAD software. The roof rack has been meticulously designed to become an integral part of the antenna system rather than building the antenna around a random rack. The fully functional roof rack can also be used for carrying almost any kind of cargo, except fuel and light flammables.
The all-welded lightweight aluminum construction of the ST-940B HF Mobile antenna provides physical strength, excellent tuning point stability and protects the mechanical parts of the antenna from damage. Made to the highest quality standards and with extensive knowledge of materials, the construction is free of environmental problems such as corrosion due to dissimilar metal joints, UV degrading, low temperature cracking and dehermetization.
The shock-sensitive components of the system are protected by aircraft-type shock absorbing vibroframe. The micro-processor controlled interface of the Stealth ST-940B allows for flexibility in connection with any type of mobile HF transceiver.

Features:

• Power Rating – The antenna is rated for a maximum RF power of 150W PEP.
• Fully Automatic Operation – The motorized folding loop can change its position within seconds from inside the moving vehicle at any time. The antenna is designed so that it normally operates when the hinged loop is raised. However to support ALE/CALM and other networking functions of modern transceivers, the antenna can work for reception even when the loop is folded down. This feature allows for the vehicle to maintain a “hidden look” till transmission is required.
• Multipurpose Graphic Remote Control – The rugged construction of the antenna remote control unit allows control and observation of the current antenna position and tuning parameters, through large, easily readable mnemonic symbols and messages on the bright OLED display that is installed on the vehicle’s dashboard.
• Intelligently Designed User Interface – It allows customers to change warning sound signals as well as provides computerized access for radio technicians to the system parameter settings and diagnostics.
• Easy Installation and Operation – The Antenna is easily installable on the hard roof of vehicles, end both installation & operation does not require highly qualified radio personnel.

Night of Nights 10

This is a real cool video~
One day I might be half as good at sending CW~
Hat Tip to my Friend & Elmer, Bill (N8AM) for sharing this with me.



Video of 'DA', also known as Denice Stoops, the first female telegrapher who worked at KPH until the end of commercial morse operations and closure of the station in 1998.

Denice is seen here sending the closing transmissions of the MRHS (see them at www.radiomarine.org ) Night of Nights 10. Each year (in this case exactly 10 years) to the minute, that commercial morse operations ceased in the United States, former RCA shore station KPH comes alive to pay tribute to those who came before us to honor their skill and talents. Many other maritime shore stations and vessels join in, and thousands of people all over the world tune in each year to pay tribute, and copy the CW 'music' once again commanding the airwaves.

This video was shot in the control room at the KPH, KSM, KFS transmitter site and brought to a close Night of Nights X. The KPH 'wheel' is being sent in the beginning of the video before transmitter supervisor Steve Hawes 'pulls the plug' and connects DA's chrome Vibroplex bug to the panel to key all the transmitters at once. The whole building is electrified by the transmitters and the spirit of the men (and women) that were the only connection between those at sea and the world. It is an emotional experience to be part of such an event.
