The VGC BHM-88 Bluetooth speaker microphone brings a simple and effective wireless option to amateur radio operators who want fewer cables and more mobility. Designed for the VGC N Series radios and now compatible with the ICOM IC-705, it provides a compact handheld device that delivers remote microphone control, clear audio and useful on-screen data.

With its built-in GPS receiver, electronic compass, 1.44-inch display and USB-C charging, the BHM-88 suits both mobile and portable radio operation. Below are its key features, use cases, pairing steps and overall strengths to help you decide if it fits your station or field setup.

Key Specifications of the VGC BHM-88

The BHM-88 integrates Bluetooth audio, navigation data and a bright display into one unit, making it a capable upgrade for both mobile and fixed operators. Its compact build and sensible power design make it a practical choice for everyday radio use.

Wireless Connectivity & Compatibility

• Operates over Bluetooth in the 2.4–2.485 GHz ISM band for both transmit and receive audio.
• Typical operating range of up to approximately 10 metres, suitable for vehicles, portable work or a tidy home shack.
• Originally designed for the VGC N Series; recent firmware now adds full compatibility with the ICOM IC-705.
• Internal mode settings must be adjusted when switching between VGC and ICOM to ensure all microphone functions operate correctly.

Built-in GPS, Compass and Display Features

• Integrated GPS receiver and electronic compass provide live heading and location information directly on the microphone.
• 1.44-inch LCD presents key data at a glance, reducing reliance on the radio’s own display.
• Screen layout is optimised for essential information, helping portable operators maintain situational awareness without extra devices.
• Detachable belt clip allows easy carry and positioning during mobile, pedestrian or portable operation.

Power, Charging and Physical Build

• Battery: 1200 mAh lithium-ion pack for typical day-to-day operating sessions.
• Charging: USB-C port, easily powered from modern phone chargers, power banks or in-vehicle USB outlets.
• Operating voltage: 3.7 V nominal, with recommended charging from a 5 V, 1 A power source.
• Physical size: Approx. 98.5 × 69.5 × 30 mm, making it compact for handheld or clipped use.
• Weight: Around 135 g, light enough for long periods of wear on a belt or lanyard.
• Construction and finish feel well suited to both mobile and outdoor use, with a removable belt clip offering extra flexibility.

Use Cases – How It Fits in the Shack & Field

The wireless BHM-88 sits naturally in a wide range of amateur radio scenarios, helping to tidy installations and improve operator comfort:

• Vehicle and mobile operation – Lose the trailing mic cable while keeping the main radio securely mounted out of the way.
• Portable and field use – GPS and compass functions support operators on summits, in parks or during outdoor events.
• Base station operation – Even in the shack, wireless control allows you to move around freely and keep the operating desk uncluttered.
• Dual-radio setups – Owners of both VGC N Series radios and an IC-705 can share a single microphone between systems.

For the best experience, keep the microphone within roughly 10 metres of the paired radio and check battery status before long operating sessions. For extended outings, carrying a USB-C cable and a small power bank or in-vehicle charger is strongly recommended.

Setup Guide: Pairing & Operating the BHM-88

Pairing with VGC N Series Radios

• Power on the VGC N Series radio.
• Enable Bluetooth in the radio’s menu system.
• Place the BHM-88 into Bluetooth pairing mode.
• Select the BHM-88 microphone from the radio’s Bluetooth device list.
• Confirm that both transmit and receive audio are working correctly.
• Verify that GPS and compass data are being displayed properly on the microphone screen.
• Keep the microphone and radio close together during the initial pairing and configuration process.

Compatibility with ICOM IC-705 and Other Radios

• Update the BHM-88 firmware if necessary to ensure full IC-705 compatibility.
• On the microphone, enable ICOM Mode via the internal settings menu.
• Enable Bluetooth on the ICOM IC-705.
• Select the VGC BHM-88 from the IC-705’s list of available Bluetooth devices and complete pairing.
• Carry out a short audio test to confirm stable, clean communication.
• If returning to a VGC N Series radio later, switch ICOM Mode off before attempting to pair.
• Maintaining line-of-sight where possible and staying within the recommended range helps keep the Bluetooth link stable.
