U94 USB Device


The SimRadios U94 USB device is a headset adapter built in to a U94 PTT with a large, robust three position toggle switch. Coupled with a FREE copy of our SimPTT software, this controller maps the locked “Hot Mic” to any keyboard key and also maps the momentary “PTT” position to any keyboard key and turns on the sidetone while a PTT is active. The SimRadios U94 USB accepts headset connection types: Nexus TP-120, U-93, U-174. Headset must have an electret microphone such as the David Clark H6090 or C-17. The U94 USB features a heavy duty clothing clip which can be reversed to attach to your right or left side.
