RF Investigation Services is the independent diagnostic practice of an RF and microwave engineer with four decades in the field — someone who spends the rest of the week designing transmitters, not just chasing them. That's the difference: an engineer who builds RF hardware knows exactly how it misbehaves.
Most people called to an interference problem come at it from networking or IT. I come at it from the other end of the bench — designing bespoke RF and microwave systems, where understanding emissions, antennas, mixing products and the behaviour of a transmitter is the day job.
That design work runs through K9 Electronics Ltd, a UK manufacturer of specialist RF systems for defence and security clients. The same engineering that goes into building a clean, controlled emitter is exactly what's needed to track down a dirty, unwanted one.
There's also a counter-surveillance and TSCM heritage here — years spent locating hidden and rogue transmitters that don't want to be found. Hunting a signal across a noisy spectrum, working out what it is and where it lives, isn't a sideline. It's the core craft.
Put together, that's a practice that can walk onto your site, characterise the RF environment properly, prove what's causing the problem — and then engineer and fabricate the fix in-house rather than writing it up and walking away.
Knowing how transmitters, antennas and mixers actually behave means recognising the signature of a problem fast — not working it out from a textbook on site.
Locating signals that don't want to be found is a discipline in its own right. Direction finding and signal hunting are second nature, not an occasional task.
A real workshop — CNC, fabrication, RF bench — means shielding, filters and remedies are built and fitted, not subcontracted out with a delay.
No Wi-Fi kit, boosters or radios sold here. The diagnosis has no agenda.
Findings you can act on and put in front of management — not a wall of jargon.
You know the cost of a callout before I leave the workshop. No meter running.
Based in the East Midlands, attending sites across the country.
No call centre, no script. Just an RF engineer on the phone.
