It does what it’s supposed to do. Bluetooth link to PC Windows 10 tested for rig control. Tested with AirPods to listen. Use hand mic to talk. Be aware it does not work with iCOM’s iPhone app only Android. Shop for it. It’s a bit expensive but there are good deals. The UT-133A should support push to talk on other headsets like Peltor. I haven’t tested that yet. The UT-133A version is also harder to find for sale.
I installed this module in my ID-5100A and now am using the icom android app that interfaces with my radio. I was able to pair my radio with the bluetooth input on my truck stereo and it allows me listen to traffic via my speakers.
