New U.S. Import Rules
Amateur radio enthusiasts know that background noise and interference (QRM & QRN) can make communications frustratingly difficult. Excess noise decreases signal clarity, causes misunderstandings, and makes conversations straining.
At bhi Ltd, we offer the best noise cancelling products on the market, specifically for amateur and two-way radio communications. We utilise advanced Digital Signal Processing (DSP) to actively monitor your signal, differentiate between speech, noise and interference, and attenuate only the unwanted noise. This leaves the speech much more intelligible without affecting the audio quality. The technology works in real-time, automatically adapting to changes in background noise levels or environments.

Our noise cancelling products for amateur radio enthusiasts
ParaPro EQ20-DSP noise cancelling unit with 20W audio and parametric equalisation
The ParaPro EQ20-DSP is an invaluable tool for ham radio operators. Its high-powered 20W dual channel amplifier provides plenty of clean audio for base station speakers, while the parametric equaliser lets you customise the audio to match your hearing and room acoustics. This level of customisable sound shaping isn't found in regular radios. But what makes the ParaPro EQ20-DSP truly special for hams is its adaptive DSP noise reduction technology. The advanced digital filtering can wipe out up to 40dB of ambient background noise and interference that typically interferes with transmissions. It automatically cleans up signals in real-time for noticeably clearer conversations.
NES10-2 MK4 5W DSP noise cancelling speaker
The NES10-2 MK4 packs pro-level voice clarifying power into a compact, portable unit perfect for hams. Its bhi DSP noise cancelling algorithm removes hiss, static, and other noise to enable clearer mobile and base communications. An ample 5-watt amplifier boosts volume when you need it without distortion. Convenient features like headphone monitoring, tone reduction up to 65dB, and 8 levels of adjustable noise cancellation from 8 to 40dB give exceptional flexibility. Quickly clean up signals and customise your audio experience, whether participating outdoors, in your vehicle, or at home.
In-Line Module
The bhi In-Line Module offers straightforward inline connectivity and inserts advanced bhi DSP filtering into any existing radio setup, from handhelds to base stations. Its processed, cleaned-up audio significantly reduces ear fatigue and miscommunications without setup complexity or external boxes. Just wire it between your radio and speakers, adding 12V DC power, to start reducing noise immediately while preserving voice quality. Hams can easily enhance old and new equipment for interference-free chatting.

Pre-wired module installs
If you want to turn your current radio or speaker setup into a fully DSP noise cancelling solution, you can use one of our retrofit modules and install this directly into your radio. Our products are compatible with a wide range of radios. Contact us, and we can help you understand if the module can be installed into your radio.

With advanced noise elimination technology, clear amateur radio calls and CW communications are finally possible even in extreme noise environments. But with various products available, how do you choose what’s right for your specific radio and needs?
The type of setup you have should guide your selection. For example, if you primarily use an extension speaker and/or headphones connected to your radio, then one of our In-Line modules would be more suitable.
If you just listen to the radio via its own internal speaker then one of our standalone amplified DSP noise cancelling speakers would work well.
The ParaPro EQ20-DSP stands out for amateur radio enthusiasts needing amplification to drive larger speakers or headphones while sculpting tones to match hearing loss profiles. Its high power handling equips it for big rooms.
Determining the root of your noise woes and matching that with the right product features ensures the best fit.
