1W? 5W? 10W?
Let's just skip this last, 5W is enough, and suggest you proceed to
the other lingering question. It may seem tedious, but it is the work
of measurement and validation. If you are not interested in valid
data, there was no point in buying that scope, much less plugging a
circuit into it. One has to imagine that you probably haven't had it
calibrated - but even there I would accept it conformed to spec and
you would still be treading water.
The risk you run in answering these questions is in your responses
revealing failure. We have already passed that milepost sometime ago,
all that remains is to find out if you drove through the sign saying
the bridge was washed out.
It would be intriguing to discover how your rig drove 5W through the
coil to a 48:1 mismatch. I can well imagine that the insane load
detector limited you to 5W, but the detected levels must have been in
the microvolts (hard to measure phase shift in the trace bloom).
However, these details are lost in the mist of memory, or perhaps you
would pull on our heart-strings about crippling arthritis with
dragging those "notebooks" open to that page only to suffer through
the tears of your poor vision. You might consider digitizing
everything so it is searchable, and enjoy the benefits of browsers
that are tailored for the impaired.
