[Elecraft] Power Output Specs

[Lyle Johnson]

> 1.  Does my thru-line wattmeter indicate RMS or P-P power?

Typically RMS, but there is a time constant involved in the meter 
movement, and some versions are/can be peak reading.  Keep in mind that 
most wattmeters, thru-line included, don't actually measure power but 
voltage induced in a directional coupler, and are only at their rated 
accuracy when they are terminated in the load for which thy are 
designed, usually 50 ohms non-reactive.

> 2.  Are TX/Amp power output specs given in RMS or P-P?

Usually RMS, but might be peak envelope power (PEP).  CW ratings are 
usually RMS; SSB ratings are usually PEP.

The KPA100, for example, is rated at 100 watts output power into a 
50-ohm non-reactive load.  If you are in CW, this is the carrier (RMS) 
power.  If you are in SSB, this is the PEP rating.

Enjoy!
