RAC Ontario Sections Bulletin for 18 January, 2025

This is V_3___, Official Bulletin Station for Radio Amateurs of Canada
with this week's bulletin.

NATIONAL/INTERNATIONAL NEWS

1. January-February 2025 TCA is now available

The digital (eTCA) version of the January-February 2025 TCA is now available for viewing or download.
The paper version is now at the printer.

2.  ARRL Reports DXCC Application Processing Caught Up

DXCC® application processing is back to typical processing times.

In October, we reported that the ARRL DXCC® System had been returned to service following work that was completed to ensure the security and integrity of the system following the cyber-attack in May. Over 4,000 DXCC applications have been logged into the system for processing since returning the system to service.

We are currently processing applications submitted in December, and we continue to mail orders for paper DXCC certificates and endorsement stickers. There were 315 certificates mailed between December 27, 2024, and January 13, 2025.

3.  Ham Radio Operators Serving During California Firestorms

As the firestorms across Southern California continue to threaten millions of residents, trained amateur radio operators are serving critical volunteer roles to help officials spot fires before they get out of control.  The Eaton fire burned to the top of Mount Wilson, a critical logistical post for broadcast radio and television stations. Federal agencies, air traffic control, local emergency responders, radio amateurs, and others all share tower space on the mountain.  During severe fire weather, volunteers go to preassigned locations to report conditions. Many of them are hams, using the amateur radio bands to fill in commercial mobile network weak zones.
Ray Hutchinson, AE6H, is a retired Firefighter who serves as the chief radio officer for Fire Watch. He says local clubs are key to providing the needed RF  infrastructure. “Our local club, provides linked 2-meter and 70-centimeter repeaters: one high level and one coastal, for use by Fire Watch hams during deployments. There is a formal Net Control Station (NCS) for the entirety of these events," he said.  Radio amateurs are also ready and able to serve at evacuation centers, providing support as needed.
ARRL Director of Emergency Management Josh Johnston, KE5MHV, has been on calls with the Federal Emergency Management Agency and other served  agencies offering ARRL resources. Efforts are being coordinated locally by Emergency Network Los Angeles, the Voluntary Organizations Active in Disaster (VOAD) group in Southern California.  Johnston urges hams in the affected regions to be ready to take care of themselves and their families before needing to deploy. “These are stressful events for everyone, and being a ham volunteer is really second to keeping yourself and your family safe,” said Johnston.

4.   Remotely Controlled Vehicles Over Starlink

Modern remote control (RC) radios are capable of incredible range, but they’re still only made for line-of-sight use. What if you want to control a vehicle that’s 100s of kilometers away, or even on the other side of the planet? Cellular is an option, but is limited by available infrastructure.  But what if you could beam your commands down from space?  That’s what Thingify was looking to test when they put together an experimental RC boat using a Starlink Mini for communications.
Physically, it would work on the boat. After all, it was small, light, and power-efficient. But would the network connection be up to the task of controlling the vehicle in real-time?  During ground testing, the Mini version of the Starlink receiver worked very well. Despite being roughly 1/4 the size of its predecessor, the smaller unit met or exceeded its performance on bandwidth, latency, and signal strength. 
As expected, it also drew far less power: the Mini’s power consumption peaked at around 33 watts, compared to 180 W for the larger receiver.
On the water the bandwidth was more than enough to run a high-resolution video feedback to the command center. At that time, the boat moved autonomously between waypoints, and when Thingify switched over to manual control, the latency was low enough not to be a problem. We wouldn’t recommend manually piloting a high-speed aircraft over Starlink, but for a boat that’s cruising along at 4 km/h, the lag didn’t even come into play.  The downside? Starlink is a fairly expensive proposition; you’d need to have a pretty specific mission in mind to justify the cost. The Mini receiver currently costs $599 USD, and you’ll need at least a $50 per month data plan to go with it. While this puts it out of the price range for recreational RC, Thingify notes that it’s not a bad deal if you’re looking to explore uncharted territory.

2.  Changes to the RAC Canadian Portable Operations Challenge.

We have made some changes to the points system to keep the race a little tighter, differentiate mobile operations, and continue to encourage contacts on less used frequency bands on both ends of the spectrum.
QSOs are now worth:
1 point for every contact made between 3.5 MHz and 902 MHz using regular commercial power.
2 points for every contact made between 3.5 MHz and 902 MHz from a motor vehicle, or powered by a motor vehicle.
3 points for each contact made between 3.5 MHz and 902 MHz using an independent power source like a generator, or batteries not part of a motor vehicle.
5 points for each contact made above 902 MHz or below 3.5 MHz, regardless of your power source.

We have introduced Bonus points as follows:
Each contact made with an independent power source using “green” energy is worth 1 additional point. For example, contacts made using batteries that were charged with solar or wind power, or some other form of purely independent and non-polluting energy powering your station.
Each contact made at QRP power levels (5 watts or less at radio output, regardless of mode) is worth 1 additional point.  Each contact made through a satellite is worth 1 additional point.

We have added World Wide Flora & Fauna (WWFF) entities to the list of valid multipliers. These changes will help improve the RAC Challenge by encouraging participants to try different operating styles, bands, and also have them discover other programs, like the WWFF, that they can get involved with.

QuartzFest is an ARRL Specialty Convention held in January near Quartzsite, Arizona. No other hamfest in the world brings together in one gathering so much innovation in mobile antenna systems, mobile ham shacks, recreational vehicles, portable and mobile EMCOMM systems, off-the-grid living, alternative energy
systems and radio education.
QuartzFest is special in part because it comes to life each year, rising from nothing in a remote area of the Sonoran desert in the southwestern USA. Hundreds of Hams and their families and friends choose to unplug from their daily lives, travel to and setup this desert community, and immerse themselves in this week-long one-of-a-kind ham radio, camping, learning and living event.
The educational seminars at QuartzFest offer something for everyone including those new to ham radio or even the most seasoned veteran.  See the website for more information.

3.   SCAMP Digital Mode Available in Fldigi
Simple Conversational Amateur Message Protocol (SCAMP) is a weak signal digital mode developed by Dr. Daniel Marks (KW4TI).  Originally integrated with the RFBitBanger transceiver, SCAMP is now available for broader use through the Fldigi software suite.  Like other weak signal propagation modes such as the popular FT8, SCAMP is an orthogonal frequency shift keying mode with a low symbol rate, forward error correction, and synchronous signaling. Unlike FT8 which has been designed to exchange signal reports, SCAMP must be able to communicate arbitrary messages that may be required in an emergency situation. [1]
For additional information, view KW4TI’s video presentation (youtube - open research institute) on SCAMP.

4.  Single Crystal Electrode Lithium Ion Batteries Last a Long Time Researchers have been testing a new type of lithium ion battery that uses single-crystal  electrodes. Over several years, they’ve found that the technology could keep 80% of its capacity after 20,000 charge and discharge cycles. For reference, a conventional lithium cell reaches 80% capacity after about 2,400 cycles.  The researchers say that the number of cycles would be equivalent to driving about 8 million kilometers in an electric vehicle. This is within striking distance of having the battery last longer than the other parts of the vehicle. The researchers employed synchrotron x-ray diffraction to study the wear on the electrodes. One interesting result is that after use, the single-crystal electrode showed very little
degradation. According to reports, the batteries are already in production and they expect to see them used more often in the near future.
