In juli I took some hortensia cuttings and rooted them in a glass of water. Today I potted them up in some compost!

They will be growing in there over the next season and will be planted put next fall hopefully!

What is on my mind?

Spring in the garden.

And things I need to plant now that we have night time temperatures above 5c. Hopefully the last frost of the season.

Spot of reading leads me back to comfrey as something I should plant about now.

Had some in the garden out the back, probably time to plant more.

Something I just learned, you can propagate them from root cuttings; https://www.youtube.com/watch?v=M4GiBaeKdJ4

This weekend was a little meh on 10 meters. The propagation was just not there really, and I only managed to get 3 SSB contacts. The rest are all FT8/FT4, and ehh. Even that was slow. Hopefully whatever is going on with the atmosphere clears up for next weekend.

Everyone wants to find a way to propagate the ecologically important Hawai'i native tree 'ohi'a lehua (metrosideros polymorpha), but 'ohi'a lehua knows exactly where it wants to grow: 15 feet in the air, on top of a shipping container in the jungle, on the rotting 2x4 holding some solar panels. Just LOOK at how many 'ohi'a keiki were growing out of @saltphoenix 's solar setup:

(FYI, I gently pulled them out - along with their clumps of moss and leaf litter - and @saltphoenix and I split them between ourselves so we could both try to grow them down here on the ground 😅)

Radio Exterior de Espana, 2nd Chinese Service Edition

Picture Original

REE Chinese had only rebroadcast their September 1 program seven days later, on September 8, but last night, September 15, they carried something new: a program on southern Spain, mainly about Andalusia, its history and some folk customs, and a short portrait of Andalusia-born singer Joaquín Sabina.

And while the first two once-a-week transmissions were disappointing, this one is really the kind of programs that I had hoped for.

What is missing is the news, but it probably wouldn’t make much sense to include those in a service that only airs once a week.

And they still haven’t posted the podcast of this latest program, although it has probably been ready since Saturday. 🤦 That’s so much the worse as shortwave propagation on the higher frequencies was bad last night (Sept 15). For a variety of reasons, this program probably didn’t have as many listeners as it could have had, and as it would deserve.

This Weekend’s Music Garden & Propagation Outlook

Canada

Pop Shop Radio airs via Winsen on the Aller, Germany, on 6160 kHz from 14:00 to 15:00 UTC, and via Channel 292 (state of Bavaria, probably also Germany) on 9670 kHz from 22:00 to 23:00 UTC. A number of transmissions can also be heard via WRMI, FL, USA.

Finland

One station – Scandinavian Weekend Radio – on the air (on Saturday), one – Realmix – taking an autumn break.

United Kingdom

Radio Six will be on shortwave via Channel 292, on 9670 kHz from 21:00 to 22:00 UTC. Tony Currie is scheduled to play sophisticated sounds for late listening, from the Great Music Garden, Lismore, Scotland.

Also from Scotland, via Channel 292 in Germany and WRMI in the United States, Radio Tumbril can be heard with its program of classical music – click the following links for times, frequencies, and the current playlist.

For the whole world of music, there’s Alan Roe’s "Music on Shortwave" selection (40 pdf pages), round the clock, all over the weeks.

Propagation Outlook

High-frequency propagation remains generally good, writes the Radio Society of Great Britain, but "[n]ext week NOAA predicts the solar flux index will decline to 160, and then perhaps 125. Unsettled geomagnetic conditions are forecast until the 10 September, with a maximum Kp index of 4 predicted".

Stockholm Radio shouldn’t be read as a general propagation forecaster, but as one that describes HF communications from various parts of the world with the Swedish service provider’s high-powered transmitters and receivers […], all situated in Sweden. You can see the difference, depending on distance, when comparing places like Copenhagen and Calcutta.

This tutorial might help to understand the criteria that define good or bad propagation conditions.
General rules are that a high solar flux and a low KP index are best for shortwave reception. A solar flux from 80 to 110 counts as average, and KPIs from 0 to 3 count as really calm (and therefore good for high frequency signals).

HF vs VHF/UHF: Which Band Should You Start With?

2,730 words, 14 minutes read time.

There’s something raw and satisfying about firing up a radio and knowing you’re about to push a signal beyond the walls of your home, past the skyline, maybe even across oceans. It’s not a toy, not a gimmick—it’s a connection forged through skill, knowledge, and the right gear. But before you spin the dial and key the mic, there’s a decision to make: do you start with the hard-hitting world of HF, or the precision and practicality of VHF/UHF?

This isn’t about passing a test. It’s about choosing the path that will challenge you, teach you, and deliver the kind of results that make radio more than a hobby. It’s about starting where the signal meets your ambition.

The Straight Answer

VHF/UHF is the fast track to getting on the air and making solid contacts close to home. If your goal is reliable comms, quick access to local nets, and gear that’s compact and efficient, this is your arena. It’s also the training ground where you’ll sharpen your skills before stepping into the deeper water.

HF is for those who want reach—real reach. We’re talking contacts across continents, late-night signal hunts, and the thrill of cracking through atmospheric noise to land a QSO on the other side of the planet. It’s more gear, more learning, and more challenge—but the reward is unmatched.

What These Bands Really Are

HF—or High Frequency—covers 3 to 30 MHz. This is where propagation becomes an art form, where the ionosphere turns raw RF energy into a ticket to anywhere on the globe. These bands are unpredictable, influenced by sunspots, seasons, and time of day. It’s part science, part instinct, and all about knowing how to read the sky.

VHF and UHF—Very High and Ultra High Frequency—run from 30 MHz to 3 GHz. These bands are clean, sharp, and perfect for local or regional comms. Signals are typically line-of-sight, which means antennas and terrain matter as much as power. They excel at practicality: emergency comms, quick QSO check-ins, and portable ops that keep you connected without a massive footprint.

The Factors That Count

This isn’t about shiny radios and spec sheets. It’s about what you actually want out of the game. Are you looking to join local nets, support emergency services, or keep a reliable rig in your truck for when things go sideways? Then VHF/UHF gives you everything you need without the learning curve of HF.

But if the pull of long-distance DX, chasing rare stations, and experimenting with antennas keeps you up at night, HF is where you should start. It demands more—more cash, more space, more knowledge—but it pays back with a sense of accomplishment that can’t be bought off the shelf.

Budget isn’t a small detail here. A solid handheld VHF/UHF rig can be had for less than a tank of gas in a full-size pickup. A decent HF station, on the other hand, might set you back the cost of a weekend fishing boat. But one isn’t better than the other—it’s about matching the investment to your goals.

VHF/UHF: The Ground Game

Starting with VHF/UHF is like learning to box before stepping into MMA. It’s straightforward but demands discipline. Handheld transceivers—HTs—are compact and affordable, perfect for learning the ropes. But don’t expect miracles from the stock antenna; swap it out for a quality whip or mount a mag antenna on your vehicle for real performance.

With repeaters, you can stretch your reach far beyond line-of-sight, check into local nets, and get involved in community events. Want to go mobile? Install a 50-watt mobile rig in your truck and you’ll have a reliable comms system ready for road trips or emergency deployments.

VHF/UHF builds fundamentals—how to make clean contacts, work repeaters, and operate with confidence. It’s practical, immediate, and a perfect launchpad into the deeper world of radio.

HF: The Long Game

HF is where things get serious. This isn’t plug-and-play. It’s about building a station, learning propagation, and fine-tuning antennas until the SWR meter tells you it’s good enough to chase DX halfway around the world.

A starter HF station typically includes a 100-watt transceiver, a good power supply, and a wire antenna—dipole, end-fed, or vertical. Antenna placement is critical, and tuning can be a ritual in itself. But when you hear a faint call from a station thousands of miles away and your reply punches through, you’ll know why HF commands respect.

Each band has its character. Twenty meters is the workhorse for daytime DX, forty meters handles regional chatter and night ops, and ten meters can explode with activity when the solar cycle peaks. Mastering these nuances takes time, but the payoff is the thrill of global reach.

Antennas: The Real Workhorses

Forget the myth that the radio makes the operator. That kind of thinking belongs to catalog shoppers, not builders. The truth is simple: the antenna is the kingmaker. A thousand-dollar rig feeding into a poor antenna will perform worse than a budget transceiver pushing into a properly tuned wire or vertical. The difference isn’t subtle—it’s night and day, and anyone who’s spent time in the field will tell you the same.

On VHF/UHF, the antenna determines whether your signal clears the ridge line or dies in the driveway. A simple upgrade from the stock “rubber duck” that comes with most handhelds can transform a mediocre radio into a surprisingly capable performer. High-gain whips, roll-up J-poles, or a properly mounted base vertical with clear line of sight will stretch your reach far beyond what power alone can accomplish. For mobile operators, a mag-mount antenna on the roof of a vehicle often doubles or triples the usable range compared to a stock handheld. The lesson here is straightforward: height and gain are the great equalizers in the VHF/UHF world, and investing in the right antenna makes more difference than chasing extra watts.

When it comes to HF, the stakes climb. HF propagation is an art, and the antenna is your brush. Space, height, and design matter far more than radio model numbers. A wire dipole hung at 30 feet will outperform a low-mounted, poorly resonant vertical every time. But when height is limited—say, in an HOA environment or a tight urban lot—stealth end-fed wires, balcony-mounted loops, or compact verticals with proper ground radials can still deliver respectable results. The key is understanding trade-offs. Magnetic loops, for instance, are compact and stealthy, but they demand precise tuning and can be narrow-banded. End-fed antennas are simple to deploy, but they require a solid counterpoise and good feedline practices to avoid RF headaches.

Real operators experiment. They measure, test, and refine. They know that moving an antenna five feet higher can drop noise levels, improve SWR, and turn weak signals into clean contacts. They appreciate that an antenna isn’t just a piece of hardware—it’s a performance multiplier. And when the bands open, it’s the operator who spent time perfecting his antenna system—not the one who bought the fanciest rig—who owns the airwaves.

Digital & Data: The New Frontier

Digital modes are rewriting the rules of amateur radio, reshaping what’s possible and demanding a new kind of operator—one who understands both RF and data. The old-school crowd may swear by analog FM or SSB, but the reality is that digital voice and data modes are becoming the sharp edge of modern communication. They’re not toys. They’re not gimmicks. They’re force multipliers that give you reach, clarity, and reliability when propagation or conditions would shut other operators down.

On VHF/UHF, the big three—DMR, D-Star, and Yaesu System Fusion—have cracked open a whole new level of performance. Forget scratchy analog signals that fade into static; digital voice is crisp, clean, and cuts through background noise like a hot knife through steel. But the real magic comes from how these systems tap into linked repeater networks and internet backbones. A handheld with a good antenna can reach across the globe through a properly configured hotspot or a linked repeater. Suddenly, that local VHF rig isn’t just a short-range tool; it’s a gateway to international QSO networks, emergency nets, and round-the-clock ragchews with operators in every corner of the world.

HF operators aren’t sitting on the sidelines either. When the solar cycle dips, noise levels climb, and propagation flattens out, modes like FT8, PSK31, and JS8Call step in to do what voice sometimes can’t—pull signals out of the mud and lock down contacts with barely a whisper of RF. FT8 in particular has redefined weak-signal communication, decoding transmissions so faint they’re invisible to the human ear. Some operators scoff at the minimal keyboard interaction these modes demand, but when you’re bouncing signals across continents at 10 watts and logging contact after contact on an otherwise dead band, the power becomes undeniable.

These modes also open the door to more than just casual QSOs. JS8Call can pass digital messages across stations like a low-power, decentralized email network, invaluable for backcountry expeditions or off-grid comms where traditional infrastructure is nonexistent. PSK and RTTY are still workhorses for contesting and DXing, proving that digital versatility is more than a trend—it’s a permanent shift in how serious operators approach their craft.

And make no mistake—digital proficiency isn’t about pressing buttons. It’s about mastering station setup, interface design, and signal processing. It means understanding sound card levels, proper interfacing, and software configuration to avoid splatter and distortion. It’s about blending old-school RF fundamentals with modern networking skills to run a station that’s as sharp as it is adaptable. The analog purists might roll their eyes, but when conditions turn brutal or range becomes critical, the digital-equipped operator is the one who keeps making contacts while everyone else is spinning dials in frustration.

Building the Right Starter Kit

For VHF/UHF, the essentials are stripped down to the bones—simple, rugged, and field-ready. A quality handheld (HT) or mobile rig forms the core, but don’t get sucked into the false economy of bargain-bin radios that fizzle out after a season. Go for a unit that can take a beating, hold a charge, and deliver clean audio under stress. Pair it with an upgraded antenna—because that stock rubber duck? It’s a compromise at best. A high-gain whip for the HT or a properly tuned vertical for the mobile rig will punch through dead spots and extend your range far beyond the limits of the factory setup. Toss in spare batteries, preferably high-capacity packs or a reliable power bank, because nothing kills a field session faster than a dying rig. And don’t forget a programming cable; wrestling with tiny keypads to input repeaters or talk groups is a test of patience best avoided. A well-programmed radio is a ready radio.

HF is a different animal—bigger, meaner, and less forgiving. Here, the gear list steps up a notch, starting with a solid 100-watt transceiver. The sweet spot is a radio with robust filtering, a responsive tuner interface, and ergonomics that make long operating sessions a pleasure rather than a chore. Speaking of tuners, you’ll need one—internal or external—because a poorly matched antenna isn’t just inefficient; it’s a shortcut to frying finals. Your feed line also matters more at these frequencies. Cheap coax with high loss will bleed power before it even hits the radiator, so invest in low-loss cable rated for your bands and power level.

But the real game-changer is the antenna. On HF, it’s not an accessory—it’s the soul of your station. A dipole strung high between trees, an end-fed wire tucked along a fence line, or even a magnetic loop for stealth setups can mean the difference between pulling in distant DX and shouting into the void. Every element—height, orientation, grounding—adds up. Cut corners here, and you’ll spend countless hours wondering why everyone else hears stations you can’t.

None of this has to bankrupt you. Smart operators know that the cost of entry can be reasonable if you choose wisely. Buy once, buy right, and you’ll avoid the trap of upgrading three times before you finally get the gear you needed in the first place. Entry-level doesn’t have to mean underpowered; it means gear built to grow with you as your skills sharpen and your ambitions climb from local repeater chats to cross-continental pileups.

Growing Into the Hobby

Starting with VHF/UHF doesn’t box you in, and kicking things off on HF doesn’t chain you there forever. The smart move is to build your station like a platform—not a dead-end. Every piece of gear should be chosen with an eye toward what’s next, not just what’s now. A good power supply with plenty of headroom will run today’s 50-watt mobile rig and tomorrow’s 100-watt HF transceiver without breaking a sweat. Quality coax—low-loss, properly rated, and built to last—will serve you across both bands and save you from the frustration of replacing cheap feed lines after water intrusion or UV damage ruins them.

Versatile antennas are another key play. A solid VHF/UHF vertical can be a permanent fixture while you experiment with wires, dipoles, or loops for HF. Later, you can build out a multi-band setup without scrapping what you already own. Even simple additions like an antenna switch or a portable tuner mean you can expand without gutting your existing station.

This approach keeps you flexible. It means you’re not painting yourself into a corner with band-specific gear that loses value the minute you decide to branch out. Instead, you’re building a foundation—one capable of handling late-night DX hunts on 20 meters, weekend field ops on 2 meters, and whatever digital modes or emergency nets you decide to tackle next. Radio isn’t a single path. It’s a growing arsenal. Build like you mean it, and your station will grow with you instead of holding you back.

The Call to Action

This isn’t a hobby for the faint-hearted or the casually curious. Amateur radio is a craft that rewards patience, persistence, and a willingness to get your hands dirty with antennas, coax, and meters. It’s about testing limits, learning the quirks of the bands, and mastering tools that most people don’t even understand exist. There’s a satisfaction in making a contact over a hundred miles with nothing but a handheld, or in logging a DX station on a band that seemed dead five minutes ago. That kind of accomplishment doesn’t come from watching tutorials—it comes from rolling up your sleeves and being on the air.

So where will you plant your flag first? Will you dive into the practical, tactical world of VHF/UHF, where repeaters, local nets, and portable ops reward preparation and persistence? Or will you chase the raw, far-reaching power of HF, bending the ionosphere to your will and connecting with operators across continents? Neither path is easy. Both demand focus, discipline, and a willingness to learn the hard way.

The best operators don’t wait—they act. They experiment, iterate, and build stations that can grow with their skills. Now it’s your turn. Get on the air. Make that first call. Tinker with your setup. Test your antenna. Push the limits of what your station can do.

And if you want to keep sharpening your edge, subscribe to the newsletter. You’ll get hard-hitting gear guides, field-tested tips, and strategies that keep you one step ahead on the bands. Whether you’re logging your first VHF contact or chasing long-distance HF DX, you’ll be ready for whatever comes next on the dial. The airwaves are waiting—claim your spot.

Welp, this weekend was a total win on FT8 10 meters. I'm guessing with the solar storm that's doing it's thing, it made things wacky, 'cause I've not seen propagation like this from Western PA before. The EU was like wide open for me, and boy did I do my best to take advantage of it! 170 FT8 exchanges in total for the 3 day weekend. Phew!

I've put 2 pictures up this time, because otherwise things would have just been too muddled together. (I added the all-together map too, just for comparison) So here, enjoy checking out where I managed to exchange with at just 100 watts!
