I'm concerned that my SSB output is not matching the set power level.
Reviewing the archive on a search by ALC, I found this note. It's been
years since I've looked to see what scopes are available. Any
recommendations - remembering that cost is a factor.....maybe a Scope
that uses the PC.
Here's another part to the question....I've never used a scope to look at
RF output. I assume that takes some special circuitry.
***from W3FPR note 06/03/07***
<<The best instrument I know of to check the peak power output is a
'scope. It can indicate the instantaneous RF voltage easily and it is easy
to compare that level to a CW reference level. 'Peak indicating'
wattmeters do have a time constant to indicate the peak and can be fooled
by the audio waveform. In other words, they are not always correct when
indicating the peak output of a SSB signal.>>
