[Elecraft] Re: K3 transmitter gain setting?

[wayne burdick]

This is an internal gain calibration step that requires power to be set 
at exactly 5.0 and 50 W respectively. There's no need for an accurate 
wattmeter at this point. The K3's watt metering can optionally be 
calibrated in a later step (CONFIG:WMTR).

We'll clarify this in the manuals.
