R4UAB reports that from October 3, 2023 to October 5, 2023 images will be transmitted from the International Space Station via the SSTV protocol as part of the “About Gagarin from Space” experiment. The topic of the program is the first artificial Earth satellite, amateur radio satellites, school satellites. SSTV images will be transmitted on 145.800 MHz using a Kenwood TM-D710 transceiver. They are expected to use the PD-120 SSTV format. The scheduled start of transmission is October 03, 2023 at approximately 14:40 UTC. The end of transmission is scheduled at October 05, 2023 at approximately 18:15 UTC.

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).

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...

The Online Radio Club (MX0ONL) was formed in 2018 to promote all aspects of radio activities, especially for those unable to meet regularly at a specific physical location (hence “online”).
Online meetings are held over Zoom every Thursday evening 1930-2100 UK time.
The club also runs a multi-protocol reflector:
- DSTAR Reflector XRF994 B / DCS994 B / REF994 B
- DSTAR SmartGroup TORC2
- DMR via XLX or BrandMeister 2348140
- Yaesu System Fusion Room 37815
- Echolink Node 592933 (MX0ONL-L)
- AllStarLink Node 52585
- AmateurWire VOIP 90020

The inaugural Wisconsin Ham Radio POTA Campout will take place October 13-15 2023. The event will take place at the Clear Lake Campground in the Northern Highlands American Legion State Forest (K-7260).
This year we are opening up our campout to the greater POTA community. This event will be part social activity and part Parks on the Air activation. You can activate as little or as much as you want, in whatever mode you choose. The sky is the limit.
