Why We Buy New Radios (When the Old One Still Works)
Why do we really buy new radios? It’s rarely because the old one stopped working. We all have excuses – and that’s fine.
But sometimes, if we’re honest, we’re hoping a new radio might make us feel how we felt at the very beginning… when RF first surprised us.
In this video, I talk about what originally hooked me, why that first spark can never quite be repeated, and where the magic actually lives now. This isn’t about brands or reviews – it’s about curiosity, discovery, and why this hobby still matters long after the first radio.
I’d love to hear your story too. What was the moment that hooked you?
Most people think YouTube videos sound bad because of microphones, compression, or creators doing something wrong.
Often, it isn’t.
In this video I’m talking about the viewer side of YouTube – the things you control but probably never touch. Audio choices. Playback speed. Subtitles – including moving them so they don’t get in the way.
These aren’t tricks or hacks. They’re just tools that already exist, quietly improving the experience if you let them.
A small change to how you listen can make a bigger difference than new speakers, headphones, or blaming the algorithm.
Watch it properly.
Use the controls.

Wire Antennas, Take-Off Angles, Radiation - and Why DX Is Hard
Using antenna modelling and real-world experience, this video explores why long-haul DX depends so heavily on radiation angle, why low-angle radiation is difficult to achieve, and why antenna height matters far more than many people realise.
This is not about finding the “best” antenna. It’s about understanding what actually changes when we alter height, length, and geometry – and why frustration in amateur radio so often comes from using the right antenna at the wrong time.
All antennas discussed are practical, coax-fed, and easy to match at 50 ohms. Efficiency is not the argument here. The focus is purely on radiation behaviour and take-off angle.
Topics include:
– Radiation angle and take-off angle
– Vertical, dipole, and loop behaviour
– Benchmarking antennas at low angles
– Ground effects and coastal locations
– Noise on the low bands and receive-only antenna options
This is a stand-alone, long-form explanation intended to build understanding rather than offer shortcuts.

Real-world antenna maintenance: I drop the tower on the winch, discover why one of the 20m elements has gone AWOL, and do a quick fix before getting it back up again. Nothing dramatic – just how antennas actually behave out in the field… because 8 × antennas and 2 × radios means 16 times more problems!
Filmed off-the-cuff while larking around, with a bit of colour grading for fun. If you enjoy the practical side of keeping things working, you’ll feel right at home.

Home-Brew Tree Vertical - Does It Actually Work? (Built from Scrap)
I often say "just run a vertical up a tree and throw some radials down" – but I realised I’d never actually shown it properly.
So in this video, I build a 20m tree-supported vertical entirely from scrap: old wire, abandoned radials, questionable coax, and whatever I could find in the workshop.
No spreadsheets. No perfection. Just get something in the air and test it.
Once it was up, I compared it directly against my main field vertical using a proper A/B WSPR test – same band, same power, same stations, swapping antennas every two minutes.
The result? Doing it "properly" still buys you margin and calmness on receive – but a tree canopy and a simple ground system do not suddenly make HF impossible.
Which is good news. Because it means if all you’ve got is a bit of wire and a tree, you’re not excluded from the game.

RESULTS: What the Data Actually Says: Vertical vs Delta Loop on 40m
This video demonstrates a clean, repeatable method for comparing antennas using WSPR via fixed time slots, fixed power, and real data – not opinions. It is not about comparison done by ear, S-meters, or quick swaps – which can lead to the wrong conclusion.
What this video covers:
– A practical A/B antenna testing method using WSPR
– Why ABABAB testing beats day-to-day comparisons
– How to log RX and TX properly
– How I analysed the data using ChatGPT as a coding assistant
– Why time of day matters more than people think
What this video is NOT
– Not a propagation report
– Not a claim that one antenna is "best"
– Not sponsored or influenced
Hello ChatGPT.
I have conducted a controlled A/B antenna comparison using WSPR only.
Both antennas were tested:
at the same station
on the same band
at the same power
within clearly defined time windows
Nothing else was changed.
I am about to send you three files:
1 The Timeslots Log in UTC (which antenna was in use and exactly what time)
2 The Receive Log in UTC (work out which antenna was in at any time via the Timeslots log)
3 The Transmit log downloaded from WSPRnet in UTC
The logs are accurate and in clear two-minute chunks – there is no need to be concerned about the times.
My timeslot log includes the antenna label for every 2-minute WSPR slot (including RX-only slots).
Your tasks:
TX analysis: Identify which antenna was in use for each transmit period. For each antenna, calculate:
– total number of reports
– number of unique reporters
– median SNR (not maximum)
– median distance
Group TX results into distance buckets:
– short haul (0–2000 km)
– medium haul (2000–4000 km)
– long haul ([greater than] 4000 km)
For each bucket, show report count and median SNR.
RX analysis: Using the RX log, separate decodes by antenna and time window.
For each antenna, calculate:
– total decode count
– median RX SNR
– median distance (if available)
Output requirements:
Present results in clear tables.
Do not declare a single winner.
Explain what each antenna appears to be better suited for – based on the data.
Focus on differences in behaviour, coverage, and application rather than preference or opinion.
Base conclusions strictly on the data provided, not on predicted behaviour
Explain how you calculated the results
I will send the files in the next message. Please confirm you are comfortable with my prompt.
Someone recently described this channel as “influencer-led”. This video explains why that label doesn’t really fit. Most of what happens here is building, fixing, breaking, experimenting, and learning – usually involving antennas, towers, contests, or the chain between the radio and the antenna.
I’m not trying to persuade anyone to buy anything. I’m trying to show the process, including the mistakes, so others feel able to have a go themselves. If something I do inspires you to try, build, fix, or experiment – then the video’s done its job.
When Ham Radio Stops Being Fun (And How to Fix It)
Sometimes ham radio just stops being fun. Your station is set up, the gear works, but it’s sitting there unused – and that can create guilt or concern that something has gone wrong.
This video is a calm, honest look at why that happens, and what you can do about it without pressure, upgrades, or guilt.
We talk about recognising life factors, small ways to re-engage, changing direction inside the hobby, and why sometimes the best thing to do is simply accept a pause.
If this has happened to you, you’re not alone – and you haven’t failed at radio.
This video is not about which antenna is best. It’s about how to test antennas in a way that removes bias, guesswork, and misleading results.
– Why time of day matters
– What must stay fixed in a fair A/B test
– Why I used this method
– How I alternated antennas cleanly
– How TX and RX are handled differently
The entire unedited WSPR session is linked so you can see exactly how the test was run.
In the next video, I’ll show the results of a 40 m night-time test where antenna behaviour really separates one from the other.
