If I am not mistaken, on "HI" (100W) that rig consumes about 9 amps
during transmit. I forget how much it uses wnen in recieve, I think
about an amp. So you use 7 amp-hours for a 3.8 hour session assuming a
10% transmit duty cycle? Much longer time available at "LO" (20W), maybe
6.6 hours?
It's been too long since I messed with a PRC-47, I forget the power
drains -and I could be off quite a bit on recieve, so this is
speculation but I think it is close.
