What radio type? With an Elecraft K3, you can use the Inhibit
pins and the <a moz-do-not-send="true"
href="https://bit.ly/K3lockout">Simple Lockout Circuit</a> I
designed with N6KR, but use a 5V linear regulated power supply
with a 10K pullup resistor to each Inhibit pin instead of Pin
1 to provide the +5V as shown (unless you are using AFSK
instead of FSK, in which case you can use the ACC port FSK pin
for the +5V).</div>

</div>
<div class="gmail_extra">Note that this is not a "First One
Wins" system; if both radios try to transmit at the same time,
both will stop transmitting until there is only one left that
is asserting PTT. This is due to a limitation of the K3
firmware (inhibited radio still closes its PTT output). I
hope to convince Elecraft to change this behavior some day.</div>
