It should be a fairly simple test, and it is on most equipment, but when I
put in a steady tone, the output changes. Even when the power is set at
100%, but the output is down to around 5 Watts, it won't sit still. The
power will jump up a few Watts, then down. Change to the next frequency,
and it seems to keep doing it. I didn't notice the problem in v. 2.028, but
by 2.032 I started seeing it.
Of course, the correct way to measure the response in this type of situation
is with 'pink noise' and a spectrum analyzer, that way, you can see the
entire audio spectrum of the radio all at once. The only problem you could
run into is if there is some type of dynamic equalization built into the
radio, which I doubt. If I can get my hands on an inexpensive pink noise
generator, I can probably do some tests like that.
