There is no substitute for an oscilloscope. There are precious few
meters that will read true peak power. Also, no meter is going to show
you peak compression or outright flat-topping (clipping) like a 'scope.
Someone mentioned that their power output went down when they turned
the compression down and would Elecraft make power output remain
constant as compression is reduced. Well, the power output (average)
is *SUPPOSED* to decrease when you reduce compression. When speech
compression is reduced, your peak-to-average power ratio increases.
The peaks remain just as high but the average power is considerably
less. This is another reason to want a 'scope to check your rig.
BTW, how many people have done a two-tone test or a double trapezoid
test for linearity? How many people even know what I am talking
about? :-)
(My first HF transmitter was a Central Electronics Multi-Phase exciter
with a whopping 10W of output. When I got done making that work again
you can bet I understood single-sideband. :-)
