The URI PTT open collector output will only sink about 50mA. You will need
to boost the output for your application. See
http://www.dmkeng.com/images/HIGH_CURRENT_PTT.pdf for a suggestion on how to
do this. If you don't need 4 amps you can use a smaller MOSFET.
Please contact me if you need any more info about this.

How much current can the PTT on a URI sink. I have a device that draws
between 200- 250 ma at 5vdc and don't want to smoke it.
