I'm wanting everyone who owns the IC-R8600 to let me know (regardless of what model you have - whether your R8600 is a Non-USA OR USA Model), whether or not you have a continuous carrier aka Birdie frequency on 133.600 MHz AM.
Could you take a few second to try this and let me know -- if you find you do have a continuous carrier on 133.600 MHz AM, set your tuning step rate to Hz and see how far you need to tune away in either direction from 133.600 before the Squelch kicks in and your R8600 goes silent.
I've upload a video as an example. In the video, I start at 133.600 MHz which is the absolute frequency of the continuous carrier aka Birdie. I then tune away from 133.600 until my Squelch (set at 30) kicks in and no audio can be heard.
