IC 7200 Digital Modes
In this video, Julian Frost (N3JF) shows how to get the Icom IC-7200 up and running on the digital modes.
The IC-7200, IC-7100, IC-7410, IC-7600 and the IC-9100 only require *one* cable connecting them to the computer, a common “A” to “B”-type USB cable. You no longer need to build a complicated cable or buy an expensive interface box, just a USB cable – one that’s commonly found in most ham shacks. The USB cable carries all the audio data to and from the radio and computer, and simultaneously allows the computer to control the radio via software.
Julian covers downloading the USB Drivers from the Icom web site, and installing them. He shows where to download the free full-featured software, “FLDigi”, covering in detail how to install it and configure it for the IC-7200. Julian demonstrates how to correctly set the radio’s power and ALC levels for transmit, and the Windows sound mixer levels for receive.
Finally, Julian demonstrates the major fatures of the software, including using, modifying and creating macros. The video culminates in a live PSK-31 two-way contact.
While this video concentrates on PSK-31, the IC-7200 is fully capable of all current HF modes when combined with software like FLDigi.

Triad Semiconductor Announces 1-Million Gate Plus Analog Configurable Array
Winston-Salem, NC (PRWEB) July 25, 2011
Triad Semiconductor Inc., the industry’s leading supplier of configurable mixed-signal ASICs, today announced the availability of its largest configurable array to date – VCA-6. The VCA-6 combines precision, high performance analog resources (more than 100 op-amps) with over a million ASIC gates on a single configurable device allowing designers to sweep up an entire board of components into a single ASIC. The VCA-6 is fabricated on IBM’s 0.18-micron 7RF process optimized for mixed signal performance and digital integration. With onshore fabrication and a complete ITAR design and supply chain, Triad and the VCA-6 are an excellent choice for defense applications seeking a cost effective way to secure design IP and manage long-term supply requirements. Applications benefiting from integration onto a VCA-6 include: software defined radio, sonar, smart sensor fusion, FPGA plus analog replacement, UAV controllers and designs needing obsolescence or end of life (EOL) replacement solutions.
The VCA-6 is based on Triad’s silicon-proven via-configurable array (VCA) technology, which allows designers to quickly and inexpensively customize analog, and digital features with lower power consumption and greater system cost savings than previous ASIC solutions.
Technical Highlights
The VCA-6 contains 320 configurable logic tiles. Each tile contains 3,150 NAND2 equivalent ASIC gates providing the array with a total of 1,008,000 ASIC gates. Unlike FPGAs, VCA-6 logic gates are not “equivalent system gates” but actual standard-cell gate primitives providing the size, performance, and power profile typical of a standard-cell digital ASIC implementation. Each logic tile also contains a 4,608-bit 2-port static RAM organized as 128 words by 36-bits. The array also contains a total of 160 Kbytes of via configurable non-volatile read-only memory (ROM) arranged as 160 1K x 8 ROMs. The distributed RAM and ROM resources can be configured into larger composite memories using Triad’s ViaWare™ memory generator. The array contains two on board PLLs for flexible timing generation. The VCA-6 has over 100 op-amps with each op-amp surrounded by configurable collections of resistors, capacitors, transistors, and switches. The analog resources are arranged into single-ended analog tiles, fully differential analog tiles, resistive DAC tiles, bias tiles, and current steering DAC tiles. A single Via-Only™ mask layer change configures and interconnects these analog and digital resources into a wide range of mixed signal circuits. If the design can be conceived of as an interconnection of op-amps, resistors, capacitors, logic and memory then the design can be implemented on a Triad VCA.
About Triad Semiconductor, Inc.
Triad Semiconductor, Inc., a privately held fabless semiconductor company with headquarters in Winston-Salem, North Carolina, develops and produces configurable mixed-signal ASICs. The company’s groundbreaking via-configurable array (VCA) technology delivers ASICs with silicon-proven analog and digital functions more quickly and at a lower cost than traditional full-custom approaches. Triad’s single-mask, Via-Only™ routing cuts engineering effort and fabrication time, resulting in fast-turn prototypes and allowing design changes to be made at minimal cost.

This is a fine little CW rig. It did a great job for me in “sweeping” the SKCC 1st Anniversary event (incl KL7 & KH6), running 20 watts to a 100′ wire antenna. However, I think I’m going to sell it (and other stuff) to finance a K3. Oh well, I will have this video to remember it by…

IMS Announces Executive and Advisory Appointments to Guide San Diego Growth
Brea, CA (PRWEB) August 22, 2011
The IMS Company, a software and systems developer in the defense and aviation industries, is expanding its presence in the San Diego area with three new executive, consulting and strategic advisory appointments, according to Ron Hopkins, Executive Vice President and General Manager of the IMS Engineering division.
Chris Burt has been appointed as Vice President of the DoD and Aerospace business group “to ensure a concentrated focus on the defense market in the Southern California region and elsewhere,” said Hopkins.
Prior to his appointment at The IMS Company, Burt was Deputy for the West Coast Aerospace domain at Thales USA Defense & Security, Inc. (TDSI) and served as key account manager for L3 Communications. Burt was previously a Service Disabled Veteran-Owned Small Business (SDVOSB) owner following two combat tours in Kuwait and Iraq as a Marine Corps officer.
The company has named Dennis Bauman as a strategic advisor, bringing decades of defense leadership, expertise and strategic insights to help guide the company’s growth in the defense market.
Since retirement from a thirty year career in the US government’s Senior Executive Service, Bauman has worked as a consultant providing strategic advice to the defense industry. Before his retirement, Bauman led the Joint Program Executive Office for the Joint Tactical Radio System as well as the Navy’s Program Executive Office for C4I and Space.
Bauman held roles such as the SPAWAR Program Director for Command, Control and Intelligence and Combat Support Applications, and Program Director for Information Warfare. Bauman also served as head of the Naval Ocean Systems Center Submarine Communications and C4I System Division.
Concurrent with his government service, Bauman was a faculty member at the University of California at San Diego Computer Science and Engineering Department for twenty years.
“IMS’ unique skills in software defined radios and in cloud computing are desperately needed in this market,” said Bauman, “and I’m pleased to help IMS accelerate its growth in the San Diego area.”
The IMS Company has also appointed Debbie Matzek as business development and strategic planning consultant for the San Diego defense market. Matzek has had a distinguished career in the San Diego Aerospace Industry. She was a leader in the success of the San Diego Chapter of the Armed Forces and Communications Association (AFCEA), where her leadership positions included Chapter Vice President, SPAWAR Systems Center AFCEA Joint C4ISR Symposium Chair (’97-’98), and Chapter President (’98-’00). She was also a member of the 2001 AFCEA San Diego Board of Directors. She has owned a consultancy for over 15 years.
Matzek began her career with General Dynamics’ Space Systems Division where she supported several Atlas II Launch Vehicle missions for the United States Air Force. She managed the development and verification of all satellite interface requirements and assisted in the development of the first Automated Requirements Verification Program. She also served as the liaison between the General Dynamics engineering team, the USAF customer, and the USAF IV&V contractor to ensure that mission requirements were approved for launch.
