[Elecraft] Antennas and Output Power - KPA-1500

[Dick Dievendorff]

It's demonstrated around the last third of this K6XX video, where K6XX shows
matches on antennas on the same frequency.

Do you use both antennas on the same frequency?  I do not have a KPA1500 but
I am curious how the tuner can remember the two different settings and know
which trained setting to use when you switch antennas. (assuming that you're
not also changing frequency).

I have two antennas for 40M, a Carolina Windom and a full-wave parasitic
sloper, the latter fed through a 4:1 balun.  The 1500's tuner handles both
antennas nicely, and I have trained it on both of them, but when I switch
from the Windom to the sloper (on an external antenna switch), the output
power changes from ~1400 watts to nearly 1700, often triggering a high
current fault.
