Has anyone noticed erratic SWR readings using SSB from the Pegasus when the
SWR gets about 1.5 to 1 or higher?  Here's the situation:

SWR less than 1.5 to 1:
absolutely no problems at anytime.

SWR above 1.5 to 1:
readings in "tune up" are stable (ie: reads steady 1.7 to 1).
readings during SSB peaks vary rapidly all over the map (anywhere from 1.7
to 10 to 1)
readings from external meter are steady and accurate

No RF in the shack.  Everything is well grounded.  No RF in audio or
computer lines.  Tried with Ten TEC  N4PY and software-- results about the
same.  Tried with 2 different antennas -- results about the same. Tried at
several power levels -- results about the same.  No internal or external
tuners used or installed.

Everything else is rock solid.

Any ideas ??

Thanks
