The Kirisun PT8100 Midband Mobile Two-Way Radio is a professional, high-power analogue transceiver purposefully built for vehicle deployment or fixed base station use. Operating in the low VHF Midband frequency range (66–88 MHz), it delivers powerful wave propagation that easily bypasses terrain obstructions. This makes it highly popular for agricultural sectors, forestry, remote utilities, and long-range rural operations.
| Front-Mounted 4W Loudspeaker | Features a powerful 4W front-facing loudspeaker designed to deliver clear audio even when the radio is mounted flush within a vehicle dashboard, reducing the need for an external speaker. |
| Comprehensive Tone Signalling | Supports built-in 2-Tone, 5-Tone and DTMF encode/decode functionality, enabling features such as group paging, private selective calling, silent interrogation and remote kill, stun and revive functions. |
| Automatic Hook Scan Function | Automatically activates a programmed channel scan when the handheld microphone is returned to its vehicle hook. Lifting the microphone stops scanning and returns the radio to its assigned channel. |
| Workforce Safety Features | Built-in Lone Worker and Security Check functions help protect personnel working remotely. If the user fails to respond within a programmed period, the radio can initiate an emergency alert. |
| Public Address System Integration | External audio output can be connected to a compatible vehicle horn or public address amplifier, allowing announcements to be made directly through the radio microphone. |
| Ambient Light Adaptive Backlight | An integrated light sensor automatically adjusts the 8-character alphanumeric display backlight according to ambient lighting conditions, improving visibility during both daytime and night-time operation. |

| Good to Know | |
| Midband Model | The Midband version operates within the specialised 66–88 MHz frequency range, making it particularly suited to applications where Midband communication systems are already in use. |
| Antenna Matching | A correctly matched Midband antenna is required. Standard VHF or UHF antennas are not suitable for this frequency range. The antenna should be properly tuned to help maintain efficient transmission and prevent excessive SWR. |
