        With KXPA
60      1.17A   2.22A   
        
        
        
        
        
20      1.20A   2.20A   7.75A   8.75A   9.50A

Trying to do some planning for Field Day battery operation. We are planning to use a KX3 at 5w, CW.

Could someone(s) give me a feeling for RX current draw. I would like this to be with the Backlight ON, and other normally ON functions activated. Likewise, what current draw should we see with key down CW at 5w?

Thanks,
