Where you live, and where your radio lives

Why I stopped trying to buy a quiet radio location, and started renting one instead.

Written with radio amateurs in mind — but not only for them. The argument underneath is about noise, land and economics, and I have tried to keep it readable if you have never touched a radio in your life. Where a technical term is unavoidable, it is explained as it appears.

For years I assumed the ultimate goal for a serious amateur radio operator was fairly simple: buy a property in the country, put up some decent antennas, and enjoy a beautifully quiet RF environment.

The problem is that in 2026, a quiet RF environment is becoming increasingly difficult to own.

For amateur operators, particularly on HF, noise is everything. We use the term QRM for man-made interference, and modern life produces an extraordinary amount of it. Switch-mode power supplies, cheap phone chargers, LED lighting, solar inverters, MPPT chargers, appliances, network equipment and countless other devices all have the potential to dump unwanted energy into the radio spectrum.

You can find the perfect location today and have it ruined tomorrow.

A neighbour installs a solar system. Somebody builds a shed next door and fills it with cheap electronics. A new owner moves onto the adjoining property. Someone buys a particularly nasty power supply online. From their perspective they have done absolutely nothing wrong. But from the perspective of an operator trying to hear a weak signal buried in the noise, the effect can be devastating.

Looking at a badly polluted HF waterfall is a little like trying to go stargazing while the person next door is letting off fireworks. The stars are still there. You just can’t see them.

The dream of owning the perfect radio property

I seriously considered solving the problem by buying somewhere specifically for radio.

At one point my wife and I looked at an old church at Craigie in New South Wales. It was around $150,000 and completely off-grid. On paper it looked almost perfect.

Being off-grid didn’t particularly concern me — in fact it could be an advantage. If I controlled the solar installation, inverter, charge controller and associated electronics, I could select equipment specifically with RF performance in mind, and track down any interference generated within my own site.

But when we visited, the neighbouring property had recently changed hands. A group of young local workers had moved in.

There was nothing wrong with them, of course. But it immediately demonstrated the fundamental weakness in the idea.

I could control my property. I could not control theirs.

And buying more land only moves the boundary further away. It doesn’t eliminate the problem.

The economics don’t make much sense either

The next logical step is to buy a larger rural property. Around Canberra and much of south-eastern Australia, that gets expensive very quickly.

My wife and I live very comfortably in our townhouse in Canberra. We love where we live. The property is worth roughly $850,000.

It isn’t a great place for HF. There isn’t much room for antennas, and even if I managed to install something substantial I would still be surrounded by houses full of electronics, solar systems and chargers. But importantly, it is a very good place to live.

If we sold it purely so I could have better radio, the replacement property might easily cost $1 million, or $1.5 million, or $2 million by the time we found a decent house with enough surrounding land to provide meaningful separation from neighbours. Then there are the transaction costs — stamp duty alone could easily consume tens of thousands.

And after spending all of that, there is still no guarantee the location will remain quiet.

That is where the economics start looking ridiculous.

Rent the radio location instead

Suppose instead I find a farmer with a genuinely quiet property, and rent a small piece of otherwise unproductive land.

For a remote station I don’t need hundreds of acres. Something in the order of 20 metres by 20 metres is already an enormous amount of useful space compared with a suburban block.

Perhaps the farmer wants $100 a month. That’s $1,200 a year. Even if the arrangement cost several times that, it is almost insignificant compared with changing houses purely to obtain better radio conditions. The stamp duty from buying another property could fund the remote station for decades.

And there is another enormous advantage.

I don’t own the RF environment.

That sounds like a disadvantage. It is actually one of the strongest parts of the model. If the environment deteriorates, I leave.

• A solar farm appears nearby — move.
• A neighbour installs a catastrophically noisy inverter — move.
• The property changes hands and the new owner causes interference — move.
• A better site becomes available somewhere else — move.

Instead of spending a million dollars trying to permanently defend one location against an unpredictable future, I can make the station itself portable.

Separate where you live from where you operate

That is the important conceptual change. Traditionally, amateur operators have tended to think: my station should be at my house. There is no technical reason that has to be true any more.

Modern radios can be controlled extremely well over IP. Audio, radio control, spectrum displays, antenna switching, rotators, power systems and environmental monitoring can all be operated remotely. Starlink has made this particularly interesting in Australia, because connectivity can now exist in places where conventional telecommunications infrastructure is almost nonexistent.

Once you accept that the operator and the radio don’t have to be in the same place, the entire problem changes. You can live where you actually want to live. Your radio can live where radio works best.

Build the station like infrastructure

There is an obvious catch: a remote station has to be engineered properly. The goal should be to make the whole installation modular and portable. Radios, computers, switching, battery systems, solar equipment, networking and monitoring should be installed so the station can effectively be picked up and relocated. Ideally the antennas follow the same philosophy.

That doesn’t mean everything has to fit into the back of a car in five minutes. It simply means avoiding unnecessary dependence on the site itself. If circumstances change, I want to be able to remove the equipment, transport it somewhere else and rebuild the station without effectively starting again.

Maintenance doesn’t necessarily require me to drive several hours either. If the site is genuinely remote, I can establish a relationship with a local electrician or technically capable tradesperson. If something needs physically resetting, reconnecting or replacing, I can pay someone to attend. If a piece of hardware fails, I can ship the replacement and talk them through the job remotely.

You could spend quite a lot of money doing that before you came anywhere close to the cost of buying a rural property specifically for amateur radio.

Australia makes the problem particularly interesting

Australia has enormous amounts of space, but that doesn’t automatically mean enormous amounts of electrically quiet space. Rooftop solar is everywhere. Rural sheds have solar. Farms have solar. Remote buildings have solar. Off-grid properties naturally use solar. That creates another source of uncertainty for HF operators, because the quality of the associated electronics varies enormously.

But Australia is also large enough that genuinely isolated locations still exist. Find somewhere with sufficient physical separation from other electrical infrastructure and the problem becomes much more manageable. At that point, instead of trying to solve everyone else’s noise sources, you primarily have to solve your own.

And that is an engineering problem I am quite happy to have.

IKARA, ALAMO, and where I eventually landed

This thinking is ultimately what led me toward the remote-station model I am now using. IKARA is my implementation of the idea in Australia. My friend Ed, K5YZW, has taken a similar path with his ALAMO system in the United States. Different stations, different locations, but essentially the same philosophy.

The scarce resource isn’t the radio. It isn’t even the antenna.

The scarce resource is a quiet piece of spectrum attached to a quiet piece of land.

Trying to permanently own that environment is expensive and increasingly uncertain. Renting access to it, and placing a portable, remotely controlled station there, changes the economics completely.

It also separates two decisions that probably should never have been tied together in the first place:

Those answers don’t have to be the same. In fact, increasingly, I think they probably shouldn’t be.
