It’s not that difficult;- The audio is no more than a pilot operating a radar advisory service where the ground controller calls the pilot out of blue with a target bearing;- With this they hear a computer generated voice and then look in the clock direction of the light on the matchbox sized display. Surely they can cope with that, bless em.
I amazed with the sensor kit available now you need any equipment upgrade;- military kit is highly optimised to find highly uncooperative targets, monitoring a massive band width, whereas these units are electrically screaming “Hi I’m here, I’ll even give you my GPS coordinates” on a well known frequency.
