HEMA Award Scheme Updates

The HEMA Summit award scheme is slowly expanding with Cyprus, East Malaysia and West Malaysia being added to it and the first activations occurring from these regions in the last few months.

There's been the first World HEMA Day on September 1st/2nd. There was a good response and all certificates have been sent out. Congratulations to Bill M0DXT and David M0YDH as joint top scorers. It looks like it will be run again around the same time next year.

A Smartphone App for Android smartphones "HEMA Assistant" is in the testing phase and spotting and listing spots with the app are working. Other features are still under development.

If you want to learn more about this amateur radio portable operating scheme and to check if there is a qualifying summit (or summits) near you please go to www.hema.org.uk.

MMDVM-Based Projects to Merge Into One Open-Source Project

From ARDC:

Funded by a grant from Amateur Radio Digital Communications (ARDC), Jonathan Naylor (G4KLX) has been hired as a full-time software developer. Jonathan is a pioneer of digital voice software, developing software for D-STAR, DMR, System Fusion, M17, NXDN, P.25, and POCSAG.

With a full-time software developer dedicated to the MMDVM project, many important tasks can be carried out, such as:

• Bug mitigation
• Improving the core code module (MMDVMHost) relating to both the display interfaces and digital modes
• Adding support for industry standards, such as Message Queuing Telemetry Transport (MQTT), which is analogous to a fast and reliable texting system that allows devices to communicate efficiently
• Creating a web-based configuration and monitoring solution
• Creating a portable UI on additional hardware platforms
• Adding KISS/AX.25 packet support along with higher speed data rates to run on existing MMDVM hardware
• Porting firmware to next generation microcontrollers

Work has started on the aforementioned software upgrades to MMDVM, and many of the long-term bugs in the software have been fixed. Regarding their progress toward improving MMDVMHost, they have added support for AX.25, and they now provide full support for amateur-driven M17 digital voice protocol.

Work is currently underway to develop 9600, 19200, and 38400 baud packet modes that support narrow bandwidth using a modulation (4FSK) similar to Digital Mobile Radio (DMR). The packet modes include support for IL2P, which is a new link layer protocol with integral forward error correction (FEC).

International Enigma Reloaded Event

The Enigma Reloaded International Event takes place September 29 through October 7, 2023. This is the 7th year of the event in which hams attempt to contact as many activating stations as possible for a chance to win the overall award. Participation certificates will also be available.

The main idea behind the Enigma event is to involve people all over the world, and specifically young people, in focusing their attention on the importance of the scientific research in general and specifically on cryptography, as main driver of most of the crucial events at the end of World War II...
