Hilltopper Redux

Got a note from the Four State QRP Group that they are kitting another run of the popular Hilltopper QRP Transceiver kits. Designed by Dave Benson, K1SWL, and kitted by the 4SQRPers, it’s been a popular kit that I’ve built in every flavor. So far. I hear they are testing a 15M version this time around so maybe I’m not yet done building Hilltoppers…

Keep an eye on the web site for additional details. There’s also a group list supporting this kit project.

The Hilltopper is a high performance, single-band CW transceiver. It is the perfect solution to your portable operation needs - small, lightweight, with wide frequency coverage and low current drain, extending the life of your portable power source. The receiver is adapted from K1SWL’s SW+ Series with minor modifications. The front-end circuitry was revised to replace the now-vanished 10.7 MHz IF transformers. The receiver output is suitable for headphone use.

The transmitter strip is a proven design using three BS170 transistors for the PA. The frequency source for both transmitting and receiving is a DDS VFO employing a Si5351 PLL module. Control for the rig is provided by an Atmel ATmega328P. This runs both the frequency control and the full-featured CW keyer.

A custom silk-screened PCB enclosure is included with the kit. No drilling or cutting required!

There are two pre-installed SMT ICs on the board, but the remainder are ALL THROUGH HOLE parts, and all jacks and connectors are board mounted, the combination making this kit very easy to assemble with no external wiring needed.

Raspberry Pi is Now a Public Company

Raspberry Pi, the precocious little single-board computer that is universally adored and used for practically everything these days, is all grown up.

Today, we’re proud to announce that Raspberry Pi has listed on the London Stock Exchange, as Raspberry Pi Holdings plc. This is a watershed moment for Raspberry Pi, and the start of a new phase in our evolution: access to the public market will enable us to build more of the products you love, faster. And the money raised by the Raspberry Pi Foundation in the IPO will support its ambitions for global impact in its second decade; for more on what the IPO means for the Foundation, check out Philip’s blog post here.

Raspberry Pi priced its IPO on the London Stock Exchange on Tuesday morning at £2.80 per share, valuing it at £542 million, or $690 million at the current exchange rate. Shortly after that, the company’s shares jumped 32% to £3.70 - the company could end up raising more than $200 million during its IPO process.

But if you have thoughts about jumping onboard the fruity train, you might have to wait a few days. Retail investors can’t buy Raspberry Pi shares just yet, as only certain institutional shareholders can trade the company’s shares right now. Retail investors will be able to buy and sell shares starting on Friday.

Raspberry Pi shares soar on stock market debut

The Cambridge-based business is known for creating affordable credit card-sized computers designed to boost coding skills among children. Shares hit 392p in early trading on Tuesday, above the initial public offering (IPO) price of 280p. Raspberry Pi chief executive Eben Upton said: “The reaction that we have received is a reflection of the world-class team that we have assembled.” He said it was also because of “the strength of the loyal community with whom we have grown.”

The single-board computer has been particularly popular in the amateur radio and maker communities where it provides a small, energy efficient computer for specific purposes in projects that may have previously been handled by a full-blown PC. This cost-effective solution is often the first choice for a plethora of hobbyists adventures.

AMSAT Mail Alias Service to End

In case you missed the news, the AMSAT mail alias service will be terminated on August 1st, 2024. The popular feature permitted mail directed to yourcallsign@amsat.org to be forwarded to any email address you chose. This feature has been a staple of satellite enthusiasts around the world for decades.

A recent AMSAT news bulletin announced the decision to end the service citing nefarious activity as the reason for termination:

Unfortunately, the unchecked rise in domain name hacking and email account high-jacking has made it impossible to sustain this service at a cost-effective level. The number of callsign@amsat.org email accounts that had been hijacked and converted to zombie spam account over the years had led many internet service providers and gateway centers to ban all @amsat.org email addresses, including those business accounts of AMSAT officers and officials. The tireless efforts of AMSAT’s all volunteer IT staff has worked for years to repair much of the damage, but AMSAT still get complaints from members who are not getting their personal emails, ANS bulletins or AMSAT-BB posts because of persistent delivery problems.

Mail aliases were once a popular way of supporting an organization while providing a relatively short, and easy to remember email address. Birthed in an era where aliasing was simple and few problems encountered, it flourished. Bad actors eventually took note of this large collection of addresses and problems followed. In the eternal war on spoofing and spamming, service providers build complex filters to trap and eliminate the most troublesome of these and one tool has been to simply ban email from entire domains. When that happens, you stop receiving email and eventually, contact AMSAT to complain about something over which they have little control.

Imagine the task of reaching out to every Internet Service Provider, big and small, globally, to explain that “amsat.org” was a legitimate concern and requesting the spam ban be lifted.

It has come to the point where the AMSAT volunteer IT staff can no longer keep up with the maintenance requirements to keep the alias mail list clean and to work with email gateways to remove blocks. And, after considerable investigation into alternative paid email services, AMSAT leadership decided that the money required to keep an email alias system alive would be better spent on building and flying satellites for its members.

This is why we can’t have nice things. The AMSAT email service has been a ham radio staple for more than two decades and it’s too bad it must be discontinued.

Persons using the Mail Alias Service should begin to migrate to different email accounts so they do not lose receipt of personal emails, AMSAT News Service Weekly Bulletins, AMSAT-BB posts, or official messages from AMSAT itself. Members are especially asked to make sure they are NOT using a callsign@amsat.org as their registered email address in the AMSAT membership portal. Members can easily change their registered member email address by logging into the portal and updating their profile.

The forwarding will end on August 1, 2024 and plans need to be made now to migrate from those addresses or risk losing email.

HAM RADIO International Amateur Radio Exhibition

HAM RADIO 2024: From June 28 to 30, everything will revolve around amateur radio in Friedrichshafen on Lake Constance. In cooperation with the organizers, the DARC, as the collaborative partner of Europe’s largest amateur radio trade fair, this meeting will open the doors to a world of almost unlimited possibilities. This big, wide world plays a significant role in the motto of HAM RADIO 2024: We celebrate 60 years of IOTA – Islands On The Air!

That’s why the motto of the 47th HAM RADIO is “60 years of Islands on the Air: technology meets adventure!”

Friedrichshafen is a city on the northern shoreline of Lake Constance (the Bodensee) in Southern Germany, near the borders of both Switzerland and Austria. Messe Friedrichshafen is one of the most modern exhibition centers in Europe. With 12 halls, 87,500 sqm exhibition space, conference rooms that can be flexibly varied to suit requirements, two central open-air grounds and its own lake. Over 27,000 sqm meters will be used from June 28-30 to host the largest amateur radio trade show in Europe. More than 11,000 visitors from 59 countries are expected to attend along with nearly 400 vendors from 30 nations.

Note it’s an “exhibition” and not a hamfest/rummage sale. The venue is a bit more upscale than typical ham radio ‘fests’ in the US and I don’t believe there’s a similarly-sized amateur radio show in the US operating under one roof.

Considered the “birth place of Germany’s aviation” where Graf Zeppelin built his world-famous Zeppelin airships and Dornier also worked on his unique aircraft. Other engineering companies located in the area and these are a mainstay of the high-tech region surrounding Lake Constance today.

Where Hamvention provided a view of what US vendors have in store for the community during the coming year, Friedrichshafen provides a look at what European vendors have in the pipeline. The exhibition is always attended by ICOM and Yaesu, but many US firms and organizations also appear year-after-year. A quick scan of the vendor list reveals ARRL, Elecraft, Orlando Hamcation and several others will be exhibiting at Ham Radio 2024.

The event also includes dozens of program tracks. Use the translation tool in your web browser if you need a little language help. Just a few of these include:

Keep an eye on YouTube soon after the event to see what all you missed. I know I will. Previous years include these videos.

Though I’ve never attended, this ham radio event certainly deserves a spot on the bucket list, maybe next year?

Wayne Green. Spirit Guide.

Wayne Green was a radio amateur and entrepreneur born in the halcyon days of hobby radio. A veteran of the Second World War, he saw first hand the impact a glut of war surplus equipment had on the amateur service. Mechanical behemoth’s from the War Department soon filled basement radio shacks and RTTY became the hot new thing in hamdom. Wayne took an interest and soon began publishing a ‘newsletter’ directed at the growing crowd of new enthusiasts.

The success of his venture didn’t escape the attention of the publisher at CQ Magazine, an enterprise that had launched just before the ban on ham radio was lifted in the United States at the end of the war in 1945. And before long, Green found himself writing an RTTY column and moving up the ranks at the new publishing enterprise.

He learned the periodical business while at CQ, and by 1960, decided the time was right to launch his own publication, 73 magazine. 73 quickly became popular, as did ‘Uncle Wayne’ and for a season, 73 was the cutting edge ham radio journal of record. It promoted homebuilding, ham radio in space, FM and repeaters, and later, computers in the ham shack – long before the ancients running the other publications would even admit that ham radio was evolving.

Of course, the story doesn’t end there. His was a life filled with successes and failures - a frequent juxtaposition for most entrepreneurs. I entered the ham radio world during the mid-70’s when Wayne’s ham radio empire was beginning a slow decline. As forward thinking as he was during the previous decades, he seemed to have become frozen in 1975. The magazine continued to prosper, mostly because scandals at ARRL provided the yin to his yang and gave him reason to continue printing it.

Eventually, it morphed into the publication for ARRL antagonists and 73 became the anti-QST magazine. And as it turns out, you can almost make a successful business out of that.

Uncle Wayne’s editorials became epic in rant, length, and subject matter. ‘Never Say Die’, a backronym on his call sign, W2NSD, often exhausted 5,000 or more words in a single editorial - enough to fill a novel every twelve months. His monthly screed covered the amateur radio scene well enough, at least in the beginning, but later these were peppered with his personal views on race relations, conspiracy theories, politics, the economy, health and education - to name just a few.

Readers were of two minds on Wayne’s penchant for sharing his opinions. They loved it or they hated it, there was no middle ground. The effect was polarizing and I happily admit, I loved it.

You didn’t read a 73 editorial in a single session. It needed to be carried around all week and imbibed slowly, five paragraphs at a session. It caused me to actually think about the views espoused and was an order of magnitude deeper than the typical ham radio editorial detritus…

Another generation and W2NSD would have been a blogger. I often try to imagine how his views would be received in this century and I’ve not managed to imagine a scenario where he would have been well-liked in that effort. After all, we have dumbed things down considerably, especially our written discourses in order to accommodate the duration of an average bowel movement.

We tweet 140 characters as though bits were expensive commodities. Blog posts exist in 200 words, preferably less. Photos and videos are much more highly prized than thoughtful commentary - unless it can be consumed in a minute or less.

21st century humans suffer from attention disorders and deeply flawed attention spans. We don’t talk on the phone anymore, we send text messages. We don’t have conversations via ham radio anymore, we exchange signal reports and grid locators. I could go on, but if you haven’t got my point by now, you won’t.

I miss Uncle Wayne’s long editorials and I’d like to someday pontificate the way he did, though no one need call me El Supremo. I don’t possess his gravitas…

Wayne Green, W2NSD became a Silent Key on September 13, 2013. He was 91.

Daylight’s Computer Tablet

I ordered a new tablet a few days ago, and it’s not an iPad. Surprised? Daylight Computer is a new manufacturer with hopes of shaking up the tablet market. I like their tagline, “The computer, de-invented”. They say the new DC-1 tablet is a “new kind of computer designed for deep focus and well-being”. What attracted me the most was the 10.5-inch e-ink display that refreshes at 60 fps. Easily visible in daylight, amber backlighting at night. Runs a custom version of Android, ships with a stylus, and looks great.

Om Malik wrote about the new device:

This is one of the most talked about devices in Silicon Valley. It was created by Daylight Computer, a company started by Anjan Katta to solve his problem — he suffers from ADHD and wanted something that allowed him few distractions and allowed him to work with intent. The reason I am excited about that new tablet is because it is optimized around reading, writing, and productivity. This is very different from the tablets we have had so far.

What the company has created is a beautiful tablet — about the size of a normal iPad Air. It is just a “little less than white,” white, with a gorgeous screen. It is very simple, elegant, and lovely. It has an e-ink like screen, and the matte monochrome paper-like display is optimized for reading, writing, and note-taking. It refreshes at 60 frames per second, a pretty big deal for these kind of displays.

This is the direction I thought Amazon was going to take the Kindle, until they basically abandoned it. It includes Bluetooth and Wifi, but there is no cellular option. Less distraction. There’s no camera. Less distraction. I like less distraction and am always on the lookout for things that will simplify life and minimize my interaction with technology.
