[Elecraft] KXP-100/KX-3 integration

[Ken Bandy]

I can normally get 4 hours or so operating my K3 at 100 watts, doing (rapid fire "contest style") SSB POTA activations with 20 Ah Bioenno batteries.

Ken, KJ9B

I have a 20AH Bioenno battery that more than adequately powers KX-3 at 10-15W for QRP activations. I've considered 2 options: 1. Geta a higher capacity battery and run both radio and amp from one battery (think the 20AH will do?

A 20Ah LiFePO4 battery will go a long while, especially if you power the
radio from it's internal battery pack, and especially if you don't CQ a
lot. One of the KX3's many strengths is that it is very miserly of
current draw on receive.
