One huge problem with the Yaesu radios is their badly designed screw in connector. At first this seemed like a good idea but in flight the cable twists and you have a stuck mic situation where noone can use their radios because the cable turned 1/8 turn and the HG/PG never bothered to program the talk time out (TOT) on their radio.
So everyone gets to listen to them breathing or their vario beeping.
It appears that the for the FT-65 Yaesu copied Kenwood/Baofeng in using a two pin side mount connector for remote mics. Much better design.
If someone is going to use a Yaseu with a screw type connector they need to program the TOT function to 30 seconds so they don’t keep jamming everyone else on the frequency.
