I think the process you describe is correct, but the numbers may be
wrong.
For an Orion without an internal tuner, as you state, pushing the
TUNE button is supposed to produce a fixed 20 watt output for tuning
an amplifier. It's true that with the TUNE button pushed, you press
PWR and the output goes to what ever you have the rf output power
set for. 40 watts output in the TUNE position by itself, would
probably overdrive most amplifiers, thus the 20w is a pretty safe
level to tune up your amp.

Subject: [TenTec] Orion & Tune button
Would some Orion owners check out this and confirm (or refute)
what I see?
I understand the operation of the TUNE button is that when you
push it, the
Orion puts out approximately 40w for tuning. You push the TUNE
button again
to turn it off (this is without the internal tuner, which I don't
have).
However, if you push the PWR button while in tune mode, the Orion
will
change to the output level set by the PWR value.
Try this, set the PWR at 80 to 100 (full power). Hit the TUNE
button. The
Orion shows about 40 watts out. Hit the PWR button and the
indicated power
jumpt up. Hit the TUNE button to stop the tuning. Now, hit the
TUNE button
to start the tune process again. On my Orion, the meter indicates
the higher
power level and then drops back to the 40 watt level. However,
this may
just be the meter as an external meter indicates that the power
output is
constant at the 40 watt level. This is when transmitting into a
dummy load.
