[TenTec] Orion v2.055 (SWR diiving amp)

[ROBERT CARROLL]

I am still using 1.372 and haven't seen SWR variations as extreme as you
report but have seen numbers like 1.0, 1.5 etc in pretty much random order.
Looking at a real meter between rig and amp showed no changes in SWR, so I
think the number displayed by the Orion wasn't particularly accurate.

Well, I like it so far.

The SP is working much better, a bit of twiddling with the mic gain and SP
got me sounding OK to my ears.  I can key the mic and not have it take off
on me.

The NR, as many have mentioned, does not work the same as 1.372.  Hitting
that button was like unplugging the antenna until a signal came along.
Impressive.  I haven't played with this version enough to tell if if is more
or less effective in terms of digging out the weak ones, but it lets more
noise through.

I have settled for now on NR of 6, which seems to drop the background noise
some yet not distort signals.  I need to use it more before I can see which
works better.  

Other than that, no quibbles here.  I mostly work CW, some SSB.  No digi
modes yet but will play with them sooner or later.  

One oddity, sometimes with v2 I see SWR High on the Orion screen when
driving my amp (500W).  It can change every TX from 1.0 or 1.3 to 4.8 or
HIGH.  The antenna is resonant, the amp meters and 2 SWR meters are agreeing
that all is well, and the amp is chugging away happily.  My first thought is
a bit of RF getting in but it never happened with v1.372.  Anyone else
notice this?

All in all, I like this version.  The sweep has stayed fixed, the SP is
fixed, the narrow BW audio is fixed.  Make the NR work like 1.372 and we are
getting awful close to a winner!
