*PRODUCT WATCH* bhi Mini Switch

The Dx Adventure Radio Club (DA-RC) has long been an advocate of bhi products and for good reason too.

In our opinion, they make radio comms a more satisfying pastime by cancelling out noise and interference that can make our hobby stress free.

The subject of this DA-RC ‘Product Watch’ — the bhi Mini Switch — is no different and whilst it’s not a noise cancelling product as such, it does play a role in enabling noise cancellation from other bhi products.


At just 53mm x 37mm x 44mm, the bhi Mini Switch is a compact two-way switch box which enables the connection of two radios to a bhi DSP noise cancelling product.

This enables you to get more ‘bang for your buck’.

Obtainable in Australia for roughly $50 AUD, including sea postage, this 0.13 kg item comes with 2 x 3.5 mm mono audio plug-to-plug leads to connect to your transceivers.

It also comes with velcro fixing pads to enable securing of the Mini Switch to your radio equipment.

Other Features:

  • Inputs: 2 x Mono 3.5mm Jack sockets.
  • Output: 1 x 3.5mm mono jack socket & 1 x 3.5mm mono jack plug lead.
  • Power handling: 3 Watts Maximum
  • Inputs: 2 x mono 3.5mm Jack sockets
