This is a good idea. I may have to look into one of these as well. A
couple things can happen, one is the current pull of the relay coil in the
amp which could overload the current rating of ttthe transceivers
. Also, when the power is removed from a relay coil, the collapsing field
causes a reverse voltage which can damage components. a way to fix this
is wire a diode reverse across the coil so the diode shorts out the
reverse voltage.
