The 13855 push-to-talk switch allows a customer an easy method for keying up a radio. The 13855 attaches to a square 10-position connector on the radio-to-modem cable that is supplied with the radio (for example, pn 29201). Pressing the button grounds the radio push-to-talk (PTT) line, which causes the radio to transmit the carrier frequency. This process is useful during radio maintenance and for troubleshooting. For example, it allows a user to sustain a transmission while measuring the forward and reflected radio transmit power with a watt meter.
