I totally agree with Crovax, that is not a solution. It would just destroy TB PvP and teamwork for the aforementioned reasons. And I agree with Eternauta's reasoning, too. It does seem like you are instigating a problem when there really isn't one...
Radios actually aren't even calibrated right and need to be boosted... you can distress for 10[?] minutes, but the ability to be encountered is longer than the distress life, meaning that there are many times when you enter into a trap and it is too late to call for help, meaning you're screwed. It should be equal.
