What action would decrease, or fail to increase, a portable radio’s ability to transmit effectively?
Explanation
Answer - D -Holding the radio towards an open window, holding the radio horizontally, or adjusting the squelch before transmitting are all actions that would decrease, or fail to increase, a portable radios ability to transmit effectively. Standing while transmitting often serves to improve the transmitting ability. This action, in effect, raises the height of the antenna on the portable radio and increases coverage area. Adjusting the squelch and pausing before transmitting will not change transmitting ability. Antenna should remain as vertical as possible. Pointing the antenna towards a window or horizontally would serve to decrease maximum transmission.
