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

Icom IC-7600 HF New Firmware

/

Icom have announced a significant firmware update for the IC-7600 HF Transceiver. The update provides a new range of functions including waterfall screen for the band scope, among many!

Improvements

  • Waterfall screens, mouse operation, and other additional functions have been added to the spectrum scope.
  • An APF AF Level setting has been added.
  • CI-V commands for antenna control, logging software and RIT/DELTA-TX have been added.
  • TX Delay (HF/50M) settings have been added to adjust the TX delay time.
  • A Standby setting has been added to remotely turn ON the IC-7600 transceiver by a command from the REMOTE jack.
  • "MOS-FET” is now the default value of “SEND Relay Type.”
