Midian Electronics’ IS-1 is an interoperability switch/gateway or a cross-band repeater maker for allowing 2 radio systems on different channels or different bands to communicate with one another. For example a UHF radio system and an HF SSB radio system can interoperate or a VHF radio system can interoperate with a UHF P25 radio system.

When the IS-1 sees COR or VOX from radio system 1, the IS-1 will give a PTT output to radio system 2 and pass the audio from radio 1 to radio 2. The IS-1 can is powered by one of the connected radio. A monitor output is available for monitoring the radio traffic or outputting to a voice recorder.

The IS-1 is similar to the ACU-M from JPS Interoperability Solutions.

Midian offers optional preconfigured cables for plug and play installation for some radios. Otherwise the IS-1 easily connects between 2 two-way radios for interoperability.
