[Elecraft] KPA1500 Power Level

[Larry (K8UT)]

Barry,

If you've connected your KPA1500 to ethernet/WiFI, you can display the 
amplifier's input watts, outputs watts, and efficiency in real time as 
you vary power levels.

Download the freeware app FANticipator here: 
https://hamprojects.info/fanticipator-kpa1500-console-and-fan-controller/

Free. Easy install. No registration. Use it once (or more) and throw it 
away.
