How about breaking out the PTT from the URI and fire a small double pole relay.<BR>
One pole PTT to the radio, and the other to turn on the fan.<BR>

Greetings,
Has anyone used the GPIO lines on a URI to active a 12 volt DC fan when the PTT is active?
I have a friend that who wants to implement this on his All-star node to keep his transmitter cool.
I guess that we would need to use a relay with the GPIO line to protect the URI?
Any thoughts or suggestions?
