This is a fictional story, based on true events from 2020.
19:18 – A Quiet Evening
It had been one of those relaxing winter evenings that scanner enthusiasts appreciate.
Dinner was finished, the coffee was still warm, and the shack was lit only by the glow of scanner displays and computer monitors. The Uniden UBCD536PT was methodically working its way through my favourites list while the Uniden UBCD396XT sat beside it with Close Call enabled.
Like most evenings in 2026, the scanners weren't particularly busy.
With most frontline emergency services now operating on encrypted TASGRN talkgroups, there wasn't much voice traffic to monitor. My focus had shifted from listening to conversations to studying the radio system itself, control channels, site activity, signal strengths, roaming patterns and the occasional unidentified transmission.
Some people had declared radio scanning dead.
I disagreed.
The hobby had simply evolved.
19:41 – That's Odd...
Without warning, the steady rhythm of scanning stopped.
The UBCD536PT had landed on a SACPAV frequency.
I looked up.
"Hmm..."
There shouldn't have been anything there worth stopping for.
Encrypted traffic normally appeared only briefly before the scanner resumed scanning. This time it lingered just long enough to make me wonder.
Maybe front-end overload?
Perhaps a nearby paging transmitter?
Possibly intermod from one of the commercial towers?
Living in an RF-rich environment, strange things occasionally happened.
I reached over to lock it out.
19:42 – Close Call!
BEEP!
The UBCD396XT suddenly screamed its unmistakable Close Call alert.
That changed everything.
Close Call only activates when a transmitter is extremely close.
This wasn't some distant police unit travelling across town or RF overload.
Someone nearby had just keyed a radio.
Seconds later...
BEEP!
Another alert.
Then another.
The signal meter on the 396XT slammed to full scale each time.
Whatever was transmitting was powerful, and very close.
19:44 – Looking Outside
Curiosity got the better of me.
I walked quietly to the lounge room window.
Nothing.
The street looked perfectly normal.
A neighbour was putting their bins out.
Kids were riding bicycles.
No flashing lights.
No sirens.
No obvious police presence.
Had my scanners fooled me?
Then I noticed something.
At the far end of the street, traffic had begun slowing.
Not stopping...
Just slowing.
Almost as though drivers had seen something ahead.
19:46 – Here They Come
A dark shape appeared around the corner.
Large.
Boxy.
Purposeful.
Even before I recognised it, the scanners told me exactly what it was.
A BearCat Police vehicle rolled quietly into view.
Behind it were several marked police vehicles.
No lights.
No sirens.
No dramatic arrival.
Just calm, deliberate movement.
The convoy continued past my house before turning into the next street.
The Close Call alerts immediately increased.
Portable radios were obviously active now.
The UBCD536PT kept pausing on SACPAV activity.
The radios themselves were painting a picture, even if I could not hear what was being said.
19:52 – Something Serious
News travels quickly through suburban streets.
Within minutes neighbours had wandered outside.
Someone mentioned hearing that an allegedly armed offender had forced entry into a nearby house after fleeing police earlier in the evening.
Another neighbour claimed police believed at least one firearm remained unaccounted for.
Whether every rumour was true hardly mattered.
One fact was obvious.
This wasn't a routine job.
If a BearCat and the Special Operations Group had been deployed, police were taking the situation extremely seriously.
20:05 – Reading the Airwaves
This was where the hobby became fascinating.
I couldn't hear a single police conversation.
Every operational transmission remained encrypted.
Yet the scanners were still telling me an incredible amount.
Close Call activations became more frequent as officers moved through the area using portable radios.
The UBCD536PT repeatedly paused whenever strong nearby transmissions briefly captured the receiver.
Watching the signal strength meter became almost as informative as listening once had been.
A burst of radio activity.
Silence.
Another burst.
Several transmissions almost simultaneously.
Then another period of quiet.
Without hearing a word, I could almost sense different phases of the operation unfolding.
Containment.
Coordination.
Movement.
Waiting.
It felt less like listening to radio traffic and more like interpreting the behaviour of the RF spectrum itself.
Every transmission was another clue.
21:11 – Resolution
After nearly an hour, the activity began slowing.
The bursts of nearby radio traffic became less frequent.
One by one, police vehicles departed.
Finally, the BearCat rolled quietly back down the street.
Whatever had happened was over.
Later that evening, police released a brief statement confirming that a wanted offender had been safely taken into custody following an incident in the area. No officers or members of the public had been injured.
The operation had ended exactly as everyone hoped.
Quietly.
Professionally.
Safely.
22:30 – Sharing the Experience
As every scanner enthusiast does after an interesting evening, I logged onto our radio scanning forum.
Within minutes, other members were asking questions.
"Did anyone else notice increased SACPAV activity?"
"Did Close Call trigger?"
"What scanners were you using?"
"How close were the police vehicles?"
The discussion quickly became highly technical.
Why did the UBCD536PT pause so reliably on those nearby transmissions?
How much RF energy is required before Close Call detects an encrypted P25 portable?
Would different antennas have produced different results?
Could the pattern of transmissions reveal how the operation progressed?
For pages, members compared receiver sensitivity, antenna types, RF behaviour and observations from around the city.
Nobody was trying to bypass encryption.
That wasn't the point.
The real interest lay in the signals intelligence.
The RF environment itself had provided a fascinating glimpse into a major police operation without revealing a single spoken word.
Reflections
People often ask whether modern encryption has killed the radio scanning hobby.
After that evening, my answer became even clearer.
Not at all.
The hobby has simply changed.
Today it's less about hearing conversations and more about understanding the invisible world of radio.
Control channels.
Signal strengths.
Coverage.
Site affiliations.
Transmission patterns.
Close Call alerts.
RF behaviour.
Sometimes your scanner tells a story without saying a single word.
And on this particular evening, it gave me a heads-up that something significant was unfolding just around the corner, long before the first police vehicle came into view.
For a scanner enthusiast, that's the kind of night you never forget.
