The only sure way is with another receiver tuned to that frequency and
preferably connected to a dummy load (a 51 ohm resistor would do).  I
have noticed that using another radio to listen to your transmission
the receiver needs to be seeing 50 ohms if it is not to produce
unwanted overload effects and fool you.

Some transceivers have a monitor function, but that, although a guide,
is not always a faithful guide.  The FT-857 does not have this
function.

I am not sure why you are concerned about transmitting for too long
without typing, that will have no ill effects apart from getting the
TX warmer and that should not be a problem.

Hope that helps.
