TI-3000

RigExpert TI-3000 is a new and powerful USB transceiver interface based on high-quality stereo codec IC, for operating phone, CW and digital modes using a personal computer.

All in one through a single USB port. Ideal interface for FT8 and WSJT modes!

TI-3000 provides:
Transceiver audio interface
Analog audio interface is a connection to transceiver audio output (external speaker connector or line output) and transceiver audio input (microphone connector or line input). Audio interface enables operating digital modes, as well as other useful functions (such as measuring levels of a signal from the air) by using a computer. Input (two channels) and output volume levels are adjusted by potentiometers on the front panel of the device.

CAT interface for various transceiver models
CAT (Computer Aided Transceiver) system provides control of transceiver frequency, operating mode and other functions by computer software. Normally, modern transceivers have serial (with various signal levels) link providing CAT interface. In RigExpert TI-3000, CAT interface port is recognized as a COM port by computer software

PTT and CW output functions
Transceivers provide PTT (Push To Talk) and CW (Continuous Wave) keyer inputs to allow setting the transmitter on or off. In RigExpert TI-3000, PTT and CW outputs are assigned to the RTS and DTR lines of a separate COM port.

British Columbia radio amateur Scott Tilley, VE7TIL, has found another “zombie satellite,” as he calls them. This time, he tracked and identified radio signals from the experimental UHF military communication satellite LES-5. Tilley says he found the satellite in what he called a geostationary “graveyard” orbit after noting a modulated carrier on 236.7487 MHz.

Current ham radio news

Radio amateurs have succeeded in providing a complete, working ventilator system to University of Florida researchers who are in the process of applying to the Food and Drug Administration for an Emergency Use Authorization (EUA). A successful submission would blaze the way for volunteers and manufacturers around the world to create low-cost, highly functional Intensive Care Unit (ICU) or anesthesia-care ventilators that offer many of the features of modern ventilators at a fraction of the typical cost. Dr. Gordon Gibby, KX4Z, who is associated with the project, said efforts to further improve the device are ongoing.

“We made a stunning improvement in accuracy of the system and measuring volumes last night at about 1 AM,” he told ARRL. “Accuracy of that particular alarm measurement went from about 300%, down to about 10%. The FDA submission is being readied, but we keep making engineering improvements.”

Gibby credited some of the primary volunteers. “Bob Benedict, KD8CGH, has provided incredible volunteer testing, now exceeding 1.6 million cycles on one crucial valve and 300,000 on another. Jack Purdum, W8TEE, is the main ‘code-cleaner’ for one of multiple teams building software, following the initial lead of Marcelo Varanda, VA3MVV. Ashhar Farhan, VU2ESE, not only created the ventilator controller schematic but the printed circuit board layout that will be part of an expected University of Florida submission.” Farhan was among the founding code writers of what we now know as Voice over Internet Protocol (VoIP).

 

Other hams worked on mechanical designs for flow measurements and retooled potential manufacturing capabilities otherwise used to produce transceivers. In another example of ham radio ingenuity, Marc Winzenried, WA9ZCO, modified a readily available lawn sprinkler to serve as a durable expiratory valve. This development enabled the ventilator to go more than 1 million breaths before significant valve issues developed, and the part can be replaced for less than $15.

The completed prototype in Florida was built using typical tools by a radio amateur, and assembled boards provided by LifeMech, a manufacturer working with the project. Farhan crafted an extendable menu structure for the Arduino Nano-based controller, and gas-flow measurements are made every few milliseconds by an I2C-based differential pressure transducer that can measure down to tiny PSI fractions, allowing the design to accurately track patient-induced variations in the volume of delivered gasses.

“Using Wenzenried’s expiratory valve, electronic on-off control at the rate of 30 Hz allows modulation of the valve to set the continuous airway pressure used to keep the patient’s lung alveoli open against virus-induced water-logging of the connective tissue,” Gibby explained. An improved software design allows faster monitoring that accurately measures patient breaths despite gas flow perturbations, with the only valve component showing wear after nearly a million cycles is the nitrile diaphragm.

“Perhaps the most surprising development was the addition of the ability to sense patient effort to take a breath and immediately switch to assisting the patient with that breath, known as ‘assist-control’ ventilation,” Gibby said. “This is expected to allow far lighter sedation of patients — potentially even no sedation — and allows patients’ crucial respiratory muscles to keep up their strength.” He said the current design goes far beyond the FDA’s guidance document for emergency ventilator development.

Radio amateurs delivered the operational control system, basic manufacturing instructions, software, and software explanation to the University of Florida on April 24.

British Columbia radio amateur Scott Tilley, VE7TIL, has found another “zombie satellite,” as he calls them. This time, he tracked and identified radio signals from the experimental UHF military communication satellite LES-5. Tilley says he found the satellite in what he called a geostationary “graveyard” orbit after noting a modulated carrier on 236.7487 MHz.

“Most zombie satellites are satellites that are no longer under human control, or have failed to some degree,” Tilley told National Public Radio (NPR) earlier this month. It’s not clear whether LES-5 is still capable of receiving commands.

LES-5 was built by MIT’s Lincoln Laboratory and launched in 1967 as part of the military’s Tactical Satellite Communication Program. It was supposed to shut down in 1972, but it continues to operate as long as its solar panels are facing the sun. Tilley told NPR that he was inspired by a ham in Cornwall who, in 2016, found an earlier satellite — LES-1 — built by the same lab and launched in 1965. What intrigued Tilley about LES-5 was that it might be the oldest functioning geostationary satellite in space.

After British Columbia went on lockdown due to the COVID-19 pandemic, Tilley found himself with a lot of free time for such a search. He located LES-5 on March 24.

From his home in Roberts Creek, British Columbia, Tilley, an amateur astronomer, routinely scans the skies for radio signals from classified objects orbiting Earth. Since he started, he’s located dozens of secret or unlisted satellites.

In 2018, while hunting for an undisclosed US government spacecraft lost in a launch mishap, he spotted the signature of IMAGE (Imager for Magnetopause-to-Aurora Global Exploration), a NASA spacecraft believed to have died in December 2005. The discovery delighted space scientists. NASA and another ham in the UK confirmed his finding. Launched in 2000 on a mission to monitor space weather, IMAGE mapped plasma patterns around Earth.
