[TenTec] Orion PEP

[Ron Castro]

Mark:

I just looked at my Orion II using a Tektronix 2712 Spectrum Analyzer, 
comparing CW output at 65% against PEP.  Using the 1 dB per major vertical 
graduation scale (sub-calibrations at .2 dB intervals), I found that the 
maximum PEP did not exceed the CW level under any condition.  I could get 
the SSB level to equal the CW level only when whistling into the microphone, 
or when running heavy processing, and even then only on sibilants.  The ALC 
on the Orions, as well as on most modern SSB rigs, are pretty good at 
holding SSB and CW output levels at their set points.

I would take PEP meter readings with a small grain of salt.  Meter 
ballistics, time constants and measurement methodologies can all effect what 
you see.
