Frequently Asked
Questions.
This counter-UAS FAQ answers the questions K9 Electronics is most commonly asked by defence procurement officers, systems integrators and government customers. Covering RF jamming technology, the AWJ architecture, procurement process, UK export control and integration support. If your question isn't covered in this counter-UAS FAQ, our engineering team is available for direct technical consultation.
Counter-UAS FAQ — RF Jamming Technology & AWJ.
How effective jamming range is determined, what AWJ is, and how it differs from older VCO-based jamming architectures.
How far can the jammer reach?
There is no single number, and the defence RF industry does not publish range figures publicly — for good reason. Effective jamming range depends on the interaction of multiple variables: the jammer's output power and antenna gain, the target device's receiver sensitivity and antenna gain, the link budget the target needs to maintain control, atmospheric and terrain conditions, and the jammer-to-signal (J/S) ratio required to disrupt the specific protocol in use.
A range figure quoted without specifying the target threat, the operating environment and the definition of "effective" is meaningless. Two systems with identical output power can produce very different operational outcomes against different threats.
The right question, and the basis on which K9 Electronics structures quotations, is: what is the threat, in what environment, and what is the operational outcome required? Once we understand your target spectrum, operational range requirement and platform constraints, our engineering team produces a link budget calculation that quantifies expected performance against that threat — and a module specification engineered to deliver it.
Range performance is provided under NDA as part of the technical specification process for authorised government organisations and defence manufacturers. Contact our engineering team →
What is AWJ (Agile Waveform Jamming)?
AWJ — Agile Waveform Jamming — is K9 Electronics' proprietary jamming architecture based on direct digital synthesis (DDS). Unlike noise jammers that broadcast undifferentiated wideband interference, AWJ generates protocol-specific waveforms designed to disrupt the specific modulation schemes used by the target threat — including OFDM (used by WiFi and most drone command links), FHSS (frequency-hopping spread spectrum), LoRa, FSK and GNSS signals.
The result is significantly higher jamming efficiency: lower power required to achieve the same operational outcome, and protocol-specific targeting that can defeat threats which generic noise jammers cannot address effectively. AWJ runs on STM32 microcontrollers driving AD9106 DDS devices, with waveform parameters configurable per programme to match the threat environment.
AWJ is implemented across the entire K9 product line, from compact 5W modules to high-power 200W modules and integrated platforms.
How does AWJ differ from VCO (Voltage-Controlled Oscillator) jamming?
VCO-based jammers are the traditional analogue approach: a voltage-controlled oscillator sweeps across a frequency range generating continuous wave or noise-modulated interference. This produces wideband signal that may or may not align with the target's actual operating frequencies, and cannot adapt to the specific protocol structure of the threat.
AWJ uses direct digital synthesis to generate waveforms with sample-level precision. Frequency hops, modulation schemes and timing patterns can be matched to the target protocol. Output is deterministic, repeatable and configurable in software — without the analogue drift, temperature sensitivity and limited frequency agility of VCO designs.
In practical terms: VCO produces noise across a band hoping to disrupt the target. AWJ produces signal that directly attacks the protocol the target is using. The efficiency difference is significant against modern protocols such as those used by commercial drones, IoT devices and military radios.
Supply, Lead Times & Format.
This part of our counter-UAS FAQ covers who K9 Electronics supplies to, typical delivery timelines, and how systems are delivered — modules, integrated platforms or kits.
Who do K9 Electronics supply to?
K9 Electronics supplies exclusively to authorised military, law enforcement and government organisations, and to defence manufacturers and government procurement teams operating under controlled programmes. We do not supply to private individuals, security companies, commercial operators, or any party that cannot evidence end-user verification.
All enquiries begin with end-user assessment as part of our standard procurement process. We are happy to engage with new customers from authorised organisations — contact us with your operational requirement, your organisation's procurement contact, and any relevant clearance or programme details.
What is the typical lead time?
Lead time depends entirely on the configuration:
- Standard module configurations from our existing product families typically deliver in 8–12 weeks from contract.
- Bespoke configurations requiring new RF design, custom mechanical enclosures or novel waveform development typically take 16–24 weeks depending on complexity.
- Programme-critical rush orders against existing module designs are sometimes possible — discussed case-by-case during the quotation stage.
For programme-critical timelines we work with customers during the technical specification phase to identify which parameters drive lead time, and where reuse of existing designs can compress delivery. Lead times are confirmed in writing as part of every quotation.
How are systems supplied — modules, integrated systems or kits?
All three formats are available depending on programme requirements:
- Modules — individual RF jamming modules from 5W to 200W supplied for customer integration into their own platforms. Includes mechanical, electrical and control interface specifications. See our Jammer Modules page for the standard range.
- Integrated systems — complete man-portable, vehicle-mounted or fixed-site systems built and tested at the K9 facility, ready for deployment. Includes RF modules, antennas, power supply, control interface and enclosure. See our Products page for example platforms.
- Kits — modules supplied alongside ancillary components (antennas, power supplies, cable assemblies, control software) for customer assembly. Used where customers want K9 modules but require their own integration process.
The right format depends on your platform integration requirements, in-house RF integration capability and operational environment.
UK Export Control & Legal Framework.
This section of the counter-UAS FAQ explains how K9 Electronics operates under UK export control law, the legal framework for RF jamming in the UK, and procurement documentation support.
Is RF jamming legal in the UK?
RF jamming is regulated under the Wireless Telegraphy Act 2006. Operating jamming equipment within the UK without specific authorisation is generally an offence.
UK jamming equipment is typically supplied for export only, or for use by Crown agencies operating under specific lawful exemption — for example HM Prisons under the Prisons (Interference with Wireless Telegraphy) Act 2012, or MOD operations under their own statutory authority.
K9 Electronics jamming products are supplied for export to authorised foreign government customers, or to UK customers operating under specific lawful authority. Equipment supplied for UK end-use carries appropriate legal notices and is restricted to authorised users only.
Are K9 Electronics registered for export control?
K9 Electronics operates within the UK export control framework administered by the Export Control Joint Unit (ECJU), part of the Department for Business and Trade. Each export is individually assessed against the UK Strategic Export Control Lists, and where licensable, export licences are obtained on a programme-specific basis prior to shipment. End-user verification and end-use assessments form part of our standard procurement process for international supply.
K9 is a UK manufacturer operating under UK export law. We do not hold US ITAR or EAR registrations and do not claim compliance with US export control regimes. For US-origin components incorporated into K9 systems, the appropriate US export licensing is handled by the component supplier.
Do you support DD Form 1494 and equivalent foreign procurement documentation?
Yes. For US programmes requiring DD Form 1494 (Application for Equipment Frequency Allocation) or related spectrum certification documentation, K9 provides the supporting technical data required to complete the form. Our engineering team is familiar with the documentation requirements and can supply emission designators, spectral mask data, ITU emission classes and other parameters specified on the form.
We also support equivalent procurement documentation for:
- UK programmes — DEFCON / DEF-STAN documentation
- NATO procurement — STANAG documentation
- LATAM programmes — CODALTEC, CEDET and equivalent national procurement bodies
Documentation packages are provided as part of the technical specification process. Contact our engineering team with your programme reference and documentation requirements.
Counter-UAS FAQ — Platform Integration & Operational Use.
How K9 modules integrate into customer platforms, operational considerations including impact on own-force communications, and duty-cycle capabilities.
Can K9 modules integrate into our existing platform?
Yes. Module integration is the most common procurement format for our defence manufacturer customers. Standard mechanical, electrical and RF interfaces are specified per programme — including:
- RF connector type — SMA, N-type, TNC or custom
- Control interface — Serial, CAN bus, discrete I/O or custom protocol
- Power supply — typically 28V DC, but configurable
- Mechanical mounting — designed around your platform's available space envelope
Integration support is provided as part of every supply contract, including interface control documents, mechanical CAD files, electrical schematics and integration testing support. On-site engineering support during integration is available for complex programmes.
Will jamming affect own-force communications?
Potentially yes — RF jamming by definition produces interference across the frequency bands it operates on, and that interference does not discriminate between hostile and friendly equipment using the same frequencies. This is a fundamental constraint of any active RF jamming system.
In practice, operational impact on own-force communications is managed through several mechanisms:
- Frequency planning — configuring the jammer to avoid own-force comms bands
- Directional antennas — focusing interference toward the threat axis rather than omnidirectionally
- Duty-cycle management — jamming is active only when needed
- Protocol-specific waveform modes — AWJ targets specific threat protocols rather than broadcasting wideband noise
Programme-specific configurations are engineered to minimise own-force impact based on the operational deployment scenario. This is one of the parameters discussed during the technical specification process.
Can the system operate continuously, or only duty-cycled?
Both are supported depending on the module configuration. Lower-power modules (5W to 25W) can typically operate continuously without thermal limitation. Higher-power modules (50W to 200W) may be specified for continuous operation, duty-cycled operation, or burst operation depending on the thermal management configuration.
Thermal management options include passive heatsinking, active fan cooling, and optional integrated heat-pipe systems for sustained high-power operation in constrained form factors. The right configuration depends on operational duty cycle, thermal environment and platform integration constraints — specified at order.
