The second public test of FT8 DXpedition Mode has shown that the mock DXpedition stations (“Foxes”) were able to work the pileups of callers (“Hounds”) at a fairly good clip. Logged data showed that 390 unique stations were copied by one or more of the three Foxes. FT8 is part of the WSJT-X digital software suite.

eHam.net News – Electrical and computer engineering students have long been fascinated by the facilitation of communication — between people, between machines and between people and machines. Today, your smartphone connects you to both people around the world and to objects in the room next to you. But in the early-1960s one electrical engineering student at the University of Toronto was embarking on a life-long passion for a different means of wireless communication: amateur radio. Dr. Donald Studney (ElecE 6T3, ECE/IBBME MASc 6T7, MD 7T0) later went on to pursue medicine, but as an undergraduate student he was beginning to form a passion shared with another electrical engineering student who came before him. The Edward S. Rogers Sr. Department of Electrical and Computer Engineering (ECE) as it is now known, is named for one of its most well-known students of the early 1920s. Edward S. Rogers Sr. invented the first radio tube that could run on house current and introduced the first batteryless radio : his all electric radio station founded in 1927 still uses the call sign CFRB after Rogers Batteryless. Ninety years after CFRB was first on the air, Dr. Studney was part of another group to make Canadian amateur radio history — and commemorate one of the most significant war efforts of Canada’s early history. “As electrical engineering students in the 1960s, we were still feeling the excitement of the Rogers era and were naturally fascinated by radio-electric communication,” says Dr. Studney. “The Hart House Amateur Radio Club was extremely well equipped so it was inevitable that decades later such an ambitious project would take root amongst some of us who shared those years on campus.” The goal of the project was simple: commemorate the 100th anniversary of the Battle of Vimy Ridge by setting up a radio station on Vimy Ridge and operate it there during the centennial tribute. The logistical considerations of such an undertaking were highly complex. “Planning began more than five years before, and involved government agencies from both Canada and France, and more than 40,000 amateur radio operators from around the world,” says Dr. Studney. “In 2015 Industry Canada issued the call sign VE100VIMY and later France issued the call sign TM100VIMY and by the centennial, amateur radio operators from across Canada came together and we fulfilled our goal of operating a special event station there.”

eHam.net News – More than 20,000 above the Earth’s surface, communication satellites orbit the planet, listening for a signal. Once they receive a signal, they repeat it and send it back down to the surface. The U.S. Air Force uses many types of satellite communications to transmit data all around the globe. With the encryption of data, the U.S. Air Force denies prying eyes the ability to read critical information. However, desperate enemies often try a number of subterfuge methods to disrupt SATCOM. This is where the 379th Expeditionary Operations Support Squadron’s Silent Sentry (OSY) flight comes into play – to protect critical satellite communication links by employing multiple weapons systems for electronic warfare. These space operators are from the 16th Space Control Squadron and the Air Force Reserves 380th Space Control Squadron at Peterson Air Force Base, Colorado Springs, Colorado. If hostile forces relied on kinetic attacks, or trying to shoot down satellites with missiles, attacks on U.S. communications would become expensive. Alternatively, those that want to deny our satellite communication capabilities are more likely to try jamming which is broadcasting powerful radio waves that overwhelm our ability to receive information. Silent Sentry’s space control mission defends against these jamming attacks. They monitor satellites and watch radio signals that the satellites send down. Normal communications have certain characteristics or “fingerprints” to them, and according to Capt. Dirk Haller, commander of Silent Sentry, when these signals look different, the Airmen of the 379th OSY know something is wrong and someone may be trying to jam them. “We watch radio signals going up and down from space and make sure that the signals we’re sending are getting where they need to go and not being interfered with,” Haller said.

eHam.net News – SUNSPOT activity across the sun is coming to a grinding halt as the burning star approaches its solar minimum cycle, scientists have spectacularly revealed. Roughly every 11 years or so, the sun reaches its so-called solar minimum, or period of relative calm across its surface. The solar minimum is a normal part of the star’s cycle when dark sunspots fade away and become less active. According to NASA scientists Holly Gilbert, sunspots are dark regions on the surface of the sun, where intense areas of magnetic force bundle up to trap all heat and light from escaping

Many thanks to SWLing Post contributor, Tom Adams (W9LBB), who left the following comment on our Tecsun PL-880 review:
Just a note re. kudos to Anon-co re. customer support.
I got a PL880 late last year, and LOVED it; so much so that I ordered a second one, the “special edition” version, both radios from Anon-co.
While waiting for the second radio to be delivered, my first one developed a bug; the AM broadcast band was dead at turn-on. Sometimes switching to FM and back to AM made it work… not good.
The second radio arrived, and it worked on short wave for about 5 minutes, and went dead. Turning it off and waiting a while brought it back… but it would die in 5 – 10 minutes again.
I wrote Anon-co about the problems, and Anna addressed the problems. After the usual fixes (reset, pulling the battery for a half hour and reinserting to reboot the processor) failed, she had me send both radios back for factory service. Anon-co covered the cost of the FedEx to get them back to Hong Kong.
A half hour ago I got a note from Anna.
The newest radio is confirmed dead; they’re replacing it.
The older radio (sent for repairs under warranty) seems to have developed a bug that the technicians have never seen before. They say that diagnosis and repair could be very difficult… therefore they are replacing THAT radio too!
I’m a happy camper with that solution… and I can’t praise Anon-co and Anna too highly! FIRST RATE customer service!!!
Thanks for sharing this feedback, Tom. I’ve had the same experience with Anon-Co over the many years I’ve done business with them. Anna is an amazing customer-focused agent and they stand by their products each and every time.
There are so few companies who retail shortwave radios these days it’s nice to know that Tecsun’s primary distributor in Hong Kong is one of the best in the business! We can buy from Anon-Co with confidence.
