Interesting. I would have thought the opposite were true. I can envision a man down scenario in which the radio operator is incapacitated, but lying on his radio with the PTT button depressed (or is experiencing great difficulty operating the radio). In that scenario, whoever is listening would know something's wrong.I would be one of those end users in a dangerous environment and I can tell you that is the exact opposite of the manufacturers desires for a commercial radio, I don't want my radio to key up UNLESS the PTT button is actually pressed by me. My Kenwood TK-5210, HT1250 and every other radio I've had over 24 years has always had a firm PTT button.
The button on the Hytera is best described as "mushy" and it doesn't take much of a press to activate. Again... this is just my first impression of the radio that I just took out of the box a few hours ago.
I'd be interested to hear a hypothetical scenario in which inadvertant PTTs can be very bad for the user. Not trying to challenge you. I just don't know all that I should, it seems.
