Having 12-volts on the keying circuit (actually, usually, 13.8-volts) is very common and I don't know of any "modern" transceiver that cannot handle the voltage.

 How much voltage will modern rigs tolerate on the keying circuit? I have 
an older amp that has a 12 volt relay. Will that fry the keying circuit 
of a modern rig?
