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.

Following the release of the latest manual, I note the emphasis on
needing to set the transmitter gain on each band, at both low (5W) and
high (50W) power levels. What isn't clear is whether it's preferable
for those with an _accurate_ Wattmeter, to set the gain based on the
K3 display or an external meter. Having previously set the K3 power
metering on the 20m band, the differences per band are not great and
perhaps academic, but I would like to know which is the best method of
setting the gain as the manual doesn't mention using an external power
meter at this point?
For what it's worth, I used an LP-100 power meter and set the gain for
the power as indicated on the external meter. Having set each band,
both at 5W and 50W, exited the menu, etc. The power levels were within
1 Watt at the 50 Watt power output setting on "tune" on every band...
The LP-100 is a calibrated unit and within 5%.
