New guy here. I just picked up an FT65 as kind of a knock around handheld. I noticed there’s a threaded insert next to the speaker microphone connection ports. Is there a specific kind of plug that has a screw to add some strain relief? I’m planning to use this thing for skiing almost always with a speaker/mic. It’d be awesome to add some robustness to that connection if that’s the intent. I noticed the ssm -17b didn’t have a screw. Is there another option?
