[TenTec] OII V2.044A

Sat Feb 26 09:45:33 PST 2011

Lee,

Interesting.  The only Hallicrafters receivers I have here are an  S-38 and 
an S-38C.  The 566 beats them :-)

It also beats my KWM-2 (on reception that is -- Collins transmit audio is  
still Collins audio) and my 75S-1 (with and without the 500 Hz filter).  My  
FT-102 does at least as well on weak HF signals, though, but fails 
miserably in  the presence of strong adjacent signals.  As has been documented 
elsewhere,  the noise blanker in the FT-102 is always on!  On 160, however, I 
think the  O II NB beats the FT-102 in the presence of QRN.

I have an old Autek QF-1 that I used to use on 144 MHz EME.  If you  need a 
narrower filter than 100 Hz, it will go down to 30-40 Hz or so.   Boy, 
though, does it ring!

Ray,
Yep for CW I use the manual notch IF I ant to make one go  away.....
The NR is, well not so good...usually I just leave it off.  Occationally 
it works OK..
To tell the truth, I have several boat achor  RX's that do much beter in 
noise.
The best is probably the  Hallicrafters SX-117...it's audio PB is on the 
low side...so it is MUCH  quieter to listen to...rather nice I might 
add. As you tune...signals just  seem to jump out of the noise.
I think a external audio filter setup would  work pretty well on OII...
Any one try one  yet?

Lee

Lee,

I hardly ever use the AN (rather useless on CW)  but I find the NR MUCH
better than 2.041XT.  Not much difference from  2.039d, though.

Seems  like the NR is a little less  distortion but the AN has more???
Anyone else  hear  that?

Lee,

Sounds good to  me.  Bring it back,  along with the waterfall!

Ray,
He is talking about the  nice  feature (which was removed in  2.044a)
that
freezes the  sweep  dsplay when you tune so that you can pounce  right on
the  signal your  after..I LOVED IT...NOW IT IS GONE    :-(

Tim,

I don't know what you mean by "freezes,"   but  when I turn the VFO knob
the
display doesn't move for  about  one  second.  That's enough for me   to
tune
close to the  desired  signal, if not right on  it.  And, yes,  the
display
width is  selectable (in  v2.044A).  I usually keep  it at 36 kHz,  which
I   find
useful on CW.  As for the  high speed sweep board, the  most   recent
word
from
John  was that it's still in  the design  stage.

I recently bought a used  Orion I  after not having  an Orion for
many  years and an quite pleased   with the  latest firmware and
operation.
I really  like the way   the  sweep display works now  in that when  you
turn
the   VFO the  display freezes and you can tune  to a signal of choice  
on
the  screen.  It's not as  elaborate as some implementations of  an
internal
scope  but I  find it to be very useful.

My   question is does the   firmware on the Orion II offer the same
or   similar  capability?  Does  it have any other sweep display  
features

in
addition to those of the Orion  I?  I  would like to  have  the ability 
to
pick a display width as  in the   past.

Any word  on the promised "High Speed  Display" that   was talked
about in years  past??

I  find I am really   enjoying the Orion and am thinking   seriously
of getting an Orion II  and  either trading this  original  Orion towards
one or selling  it to buy one. I   had forgotten how  really nice the CW
operation  (QSK in  particular) works on  the    Orion.
