I have a Bird 43 with a 100 Watt slug in line and it shows exactly 100 Watts
out on my O2 as adjusted from the factory. That being said, measuring power
with a high degree of accuracy (better than +-5%) is an art within itself
and is effected by many factors. I wouldn't put too much faith in meters on
antenna tuners since their purpose in that application is more for a
relative reading to help adjust tuner. The cost of adding a really accurate
meter that covers 1.8-30 MHz to a tuner would push the price higher than
most hams would be willing to pay, and even then, the accuracy can be
compromised by the load.

Subject: [TenTec] Orion II output power
What are list members who have ways to measure output power accurately
finding for their O2s? My MFJ 993B antenna tuner, when PWR is set at
100, generally reads around 120 FWD and a few watts reflected (when it
doesn't reach 1:1). I'm sure individual rigs differ, but I'm curious
what others are finding.
