What is the true duty cycle of a commercial or professional grade portable radio? I have seen a lot of people refer to the 5/5/90 (TX/RX/Standby) used to determine the battery life as the duty cycle as well. Is this accurate? Is it a weighted average? I know A LOT of people that have their portable radio keyed up for MUCH more than 5sec at a time.
