And if you had a KY 38 along with the PRC 77 you used 3 batteries at a time. Nothing like humping a weeks supply of batteries. 3 A day at a pound a piece if I remember right.

We used CW key more than anything with the grinders till we scored LS 6 sat com.
Hated those lithium batteries. Every troop packed at least 2 spares.
Stay safe
