...from the K3 manual:
Output Power K3/100: 0.1 W –100 W typ. Suggested max from 51-52 MHz, 85
W; 52-54, 70 W.
K3/10 (or K3/100 with PA bypassed): 0.1 W –12 W, HF-10 m; 8 W max on 6 m.
XVTR OUT (KXV3 option): -10 to +1.8 dBm. K144XV: ~10 W, 144-148 MHz.
Note: Output can be set up to 110 W. However, IMD and spurious products are
specified at 100 W, the recommended max. If a KAT3 ATU is installed, actual
output will be slightly lower (typ. loss < 0.5 dB below 28 MHz, < 0.8 dB
above).
