Friedrichshafen informal C5 meeting

/

An informal IARU Region 1 VHF/UHF/Microwave (C5) meeting at the recent Ham Radio Friedrichshafen Event discussed a New Radio Project 

Mike OE3MZC, presented details of the project, a joint initiative of the OVSV, DARC and other IARU-R1 Member societies to strengthen the experimental character of the Amateur Radio Services.

Following the meeting Mike gave a presentation to the three main Japanese amateur radio equipment manufacturers at the OVSV booth.

Tytera TYT MD-380 DMR handheld

/

EssexHams reviewer Paul, G7BHE has posted a review of a sub £150 Digital Mobile Radio (DMR)

The new Tytera TYT MD-380 DMR is a potential solutions to amateur / ham radio operators looking for an affordable radio to experience the growing in popularity of DMR

DMR works on the principle of part-RF and part-Internet. You only have to worry about the RF part. Over 40 countries are running DMR.

Liquid Metal Antenna

/

A liquid metal antenna can tune over a range of at least two times greater than systems using electronic switches 

Researchers at the North Carolina State University (NCSU) have demonstrated a reconfigurable liquid-metal prototype in the Journal of Applied Physics.

Published in a paper titled by the university, they describe how a reconfigurable liquid metal antenna driven by electrochemically controlled capillarity is a new electrochemical method for reversible, pump-free control of liquid eutectic gallium and indium (EGaIn) in a capillary.

Antennas are interesting as the shape and length of the conducting paths which form them determine their operating frequencies and radiation patterns.

“Using a liquid metal – such as eutectic gallium and indium – that can change its shape allows us to modify antenna properties more dramatically than is possible with a fixed conductor,”
— Jacob Adams, co-author of the paper and an assistant professor in the Department of Electrical and Computer Engineering at NCSU
