[Elecraft] Checking VFO accuracy using WWV

[Ron D'Eau Claire]

It all depends upon the accuracy of the test equipment, power supply, etc.
Many commercial RF power meter/dummy load combos are no more than 20%
accurate. 

Elecraft Tech support will help anyone who thinks the power output is low
with those questions.

A better analogy is a Lamborghini spec'd at 610 HP, but the dyno at the
local garage says it is putting out only 490 Hp. (I realize that is not
close to 20% low, but the impact of HP on a car's performance is much more
sensitive to horsepower than the RF output of a transmitter is on its
performance on the air.) 

What Emory said about the impact on operations of a 20% drop in RF power out
is right.

I totally disagree.  If the manufacturer specifies that the transmitter puts
out 100W, and indeed uses that as a part of the part number on the order
sheet, then it's not unreasonable for the customer to expect 100 W out.

That's like buying a Lamborghini Huracan LP 610-4 and discovering that it's
not
610 HP and four-wheel drive but two-wheel drive and 300 HP and being told,
why complain, it's still faster than a Prius.

going to detect the "deficit". It pretty much boils down to "Can he hear me"
and "Can I hear him"? If the answer is yes to both questions, then all the
rest is just fodder for textbooks and endless discussion/arguing.
