There is an difference in keeping the transistor just below the 1 dB compresion point, and with decent bias, linear.

11Meter PA's get driven (too) hard, because on the box only the output counts, not spectral purity.


That is why for amateur use we use 2 100 watt rated transistors to get 100 watt clean out.

In an 11 meter p.a they would be driven far over the rated power to 200 or 250 watts.


As said above, look at the datasheets of the manufacturer of the device and if you have an decent spectrum analiser you can see what happens if you start to overdrive the P.A.


Take in acount that the 11 meter P.A's have litle or nothing as bandpass filtering, and you know what happens...
