For the Transmitter Gain calibration, all you need is a decent dummy load. The LP-100A is not a dummy load. My 20-year old inexpensive MFJ dummy load does a good job for that. (But note it has never been abused, such as running power into it until it gets hot or smells.) A well designed dummy load

Re: [Elecraft] KX3 Suggested External Battery

I can vouch for the Bioenno Power LiPo batteries. Bought a 20 ah battery for eComm and urban field work. It only weighs 6 lbs. A 10 h only weighs 3 lbs. https://www.bioennopower.com/collections/12v-series-lifepo4-batteries Gary K9JN
