Re: Harmonic-o-Meter
It's something like this:
Voltage sampler, 1N series diode detector based 10Kw RMS meters.
Then, take the negative feedback off one side of a popular two transistor amp (2X2290, Texas Star

Re: Harmonic-o-Meter
I propose we have a new class of amplifier for the 11 meter crowd...
As it sits, we now have
A
AB1
AB2
B
C
etc.
Shouldn't somewhere, there be a class CB.....

Re: Harmonic-o-Meter
like a dispersive and compressive delay line in a radar system. What a cool idea run square wave and reconstruct. Class I amplifier (for idiot mode)

Harmonic-o-Meter
[snip]
Take an amp, change a couple caps to make the harmonic-o-meter swing
farther to the right, and call it 'your' design.

The snippet above implies a device to measure harmonic
content.

Re: Real Yahoo amp on Ebay...
I wonder if Sonny was the last person to work on it, so they are claiming it is a "sonny" built box.
That's the latest trend of 11 meter 'techs'... Take an amp built by someone else, change a

Re: hi power mobile
The cost of inverters that approach a sine wave rises as the quality of
the output waveform approaches "linearity."
It's the same sort of exercise as the digital photography evolution.

Re: hi power mobile
You can get a clean output from a converter if the sample frequency is high enough. I run tube and solid state PDM AM and make clean audio running a 75 KHz. sample frequency.
You also need a good

Re: hi power mobile
Sirs,
Only a rotating armature easily produces a sine wave.
Most inverters produce square waves, but some expensive types
produce a "modified sine wave."
