There have been reports recently of 20m openings so I left WSPR receiving and noticed the US was coming in. Switched over to FreeDV RADEV1 using my macOS version of the software called FreeDVNeo. Keyed down and on Reporter I could see that Dudley WA5QPZ in Austin Texas was receiving me. Not perfect copy, but not bad either.
Also, I'm running the release candidate of macOS 27 Golden Gate which will be out in a few days. So far it seems stable and fast.
It's a credit to his kids, my cousins, Tracey and Paul, that Robert was able to stay at his home (with visiting carers) until just about the end. I know he appreciated that very much.
I would visit every few months when in Melbourne to catch up with friends and he was always excited to see me and hear about the evolution of ham radio technology. Once I dropped in on the way back from the Rosebud Radiofest and gave him a copy of the 1956 ARRL Handbook. He leafed through it and exclaimed "nothing's changed!".
On another visit I brought along an IC-705 and showed him the waterfall display. He was impressed.
In later years he had a 2m radio but rarely was on air.
Robert, and his wife my dear aunt Peggy (who was an amazing person in her own right and the subject of this ABC program), were always kind and encouraging to me as a child and rather lost teenager.
I asked Robert about his ham radio history during a visit in 2025.
Robert got his amateur licence when he was seventeen. You had to have morse code which he had known from childhood. The morse test “wasn’t too much of a problem for me”. 15 words per minute. People would buy tapes, punch tapes, to learn the code.
Callsign was W6HWA “Hard working American”
An early transceiver he owned was a Hallicrafters SR-150. He may have had a Collins KWM-1.
He had a three element beam for 20, 40 and 80m.
At Albany road he had a tilt-over tower with a beam that did 20 and 10m.
At seventeen, Robert lived in California.
Robert had contacts both locally and overseas. Mostly just calling CQ rather than regular nets.
I showed Robert a QMX transceiver. He was amazed at the size and the fact that it did multiple bands including 80m.
We discussed the difficulty of soldering to enamelled wire used to wind toroids.
We discussed QST magazine and the ARRL.
Robert moved to Australia in 1950. He rattled off a series of addresses in California where he had lived.
We discussed WSPR beaconing and low power operation. There had been a large solar flare in the last few days.
Robert commented “how times have changed!”.
Henry Radio was a shop he used.
Robert asked if the ham radio license is easy to get these days. We discussed the levels and the fact that tests are now multiple choice rather than essay.
“A lot of water has gone under the bridge”.
Robert’s dad was a real estate broker in California. Mainly houses. Beverly Hills. Beachside communities.
I mentioned the Palisades where there have been fires. Robert said he lived there at one point but got out in time.
Robert’s older brother had married a girl from Melbourne and he came out to visit his brother. His brother was nine years older. He introduced Robert to Peg who he used to produce on radio. Robert just stayed in Australia after that. He can’t even recall going home for a visit (but he must have).
“Time marches on, we’re all getting older.”
Farewell dear Robert. I will always remember you. Ex W6HWA , VK3QA & VK3DRG SK.
It might be seen as nepotism except for the fact that she's much more qualified and certainly smarter than me. Here's her spot:
The UK has just taken its first step into the Robotaxi era, with Wayve's self-driving cars now available to book through the Uber app; but there'll still be a licensed human driver in the front to take over if needed.
Communications Minister Anika Wells has announced that the draft Digital Duty of Care law will be introduced into parliament this week, including a requirement that platforms offer the ability to 'opt-out' of their algorithms. What does this all mean?

On the trip north to the recent walk I was lucky enough to fly on a couple of different recent Airbus planes in the Qantas fleet. The last one was an A220 which has this USB power port on the seat back:
Having bought, and tested, a few Chinese chargers, I'm a bit sceptical of the Watt claims on USB-C ports but I'm happy to report that Airbus is telling the truth. The macOS WhatCable tool is very handy.
Yep, 20V at 3A = 60W. Great stuff.
The internet connection on the A220 tested at 18Mbps which is fine for general use. The plane I caught up to Sydney last week was a brand new Airbus A321-XLR and the internet speed was outstanding:
Malcolm Turnbul wouldn't need this speed but I thought it was great to see it.
Along the way are stunning beaches, charming bush tracks, and a bit of rather challenging rock scrambles. To mix things up there's a couple of river crossings, two of which required boats to pick us up.
You really can't do this without support and in our case the trip was supported and guided by Marcus from Home Comforts Hiking.
Walking south is certainly the best way to do it. We had the sun, and usually the wind at our backs.
I'd just left Drummond, Victoria, where it was 10C and I'd had the fire heating the house and arrived where it was 30C for much of the walk.
Happily I did not suffer from any blisters or other mishaps and felt faily fit probably due to my daily bush walks at home. Having said that, my feet were a bit sore at the end of each day but recovered by the morning.
Our guide Marcus did a wonderful job and the logistics all worked well bar a coffee shop that didn't open as advertised for breakfast one morning.
Could choosing your trusted news sources help support journalism in the age of AI summaries and algorithmic feeds?
Also, a new study published in the Proceedings of the National Academy of Sciences titled “Value misalignment of X’s feed algorithm” found, unsurprisingly, that the site’s algorithm prioritised engagement above all else when it generates a users “For You Page”.
What’s been revealed is that rather than simply showing more of what we agree with, the algorithm is deliberately mis-aligned in that it shows us things they know we don’t agree with so that we are prompted to comment on it, often angrily.
Finally, in the US, the Food and Drug Administration (FDA) regulates hearing aids and last week they approved Samsung Galaxy Earbuds under a category of “over the counter” hearing aids.
This follows a similar decision in 2024 about Apple AirPods Pro. Having the two biggest manufacturers of smartphones able to sell hearing aids at a fraction of the price of prescription products: $400 rather than $4,000 is a major win for people with milder types of hearing loss.

Beloved next door neighbour Hansen Yee aged just 82 has died.

The "Cheap Yellow Display" boards are a low cost board with an ESP32, a colour touch screen and a bunch of other useful I/O. I've long used them to display my solar stats (generating, using, net). I just noticed this excellent project HenrysCat esp32-cyd-ham-dashboard. There's an excellent web flash tool which works well.
It can roll through seven screens (you can turn some off if you wish). Here's a few:
The web flash tool shows this. I used the first option.
But my screen came up mirrored so I tried the second. In that case the screen was blank white so I went back to the first. When it boots up it creates a Wifi network with a captive portal. I found that the setting default to mirrored - which seems like a poor choice.
It's a great gadget to stick up in the shack. Great work to HenrysCat and claude. Source code here.
