If I'm operating a K2 at 5w cw, in S&P contest mode, I compute the
current drain under the stated conditions as follows:
conditions:
50% listening, 50% transmitting
CW 50% duty cycle
current:
200ma receive, more or less
1.0a transmit, more or less
current draw per hour:
100ma [30min rcv] + 250ma [30min xmit @ 50% duty cycle] = 350ma per hour
10Hr requires a 3.5Ahr battery
20Hr requires a 7.5Ahr battery
etc...
Is this more or less accurate, or have I missed something? Thanks.
