[TenTec] FSK and my ORION II

[David W LeJeune, Sr]

Hi, Paul

                I read your response wrong - after I replied, I looked at it
again, and noticed you said MMTTY settings.  I went there, and sure enough,
the Mark freq was set to 2295 - a shift of 170.  Boy do I feel dumb.  Set it
back to 2125 and all is well.  No need for the 170 hz RIT or the 170 Hz PBT.
Thanks, feller.  You guys are the greatest.

Dear David:

 

Check your MMTY settings. It is possible that you have the MARK/SPACE HI/LOW
setting in the Orion menu set incorrectly.

ATTN Tony:

 

                As mentioned in my phone call, in order to work true FSK on
the Orion, the manual states that you just have to select the FSK mode and
key the FSK line in the rear.  The manual also states that the passband is
automatically centered for you.  This has been my normal mod of RTTY
operation.  Moreover, transcieve operation is possible without touching the
RIT.

 

                Today, while attempting to work RTTY in the FSK mode, I had
to set the PBT to +170 to center the passband (as seen on the waterfall
display on MMTTY software).  I also had to set the RIT to +170 in order to
get true transcieve.  I checked this with several stations.

 

                After we spoke today, I reloaded 2.037J firmware to see if
that changed the situation to see if that changed anything.  It did not -
operation was still the same - had to use +170hz of PBT and +170 of RIT.
That's no problem - I programmed the USER 2 button to set this up.  

 

                I wonder if something was changed when I sent the Orion II
in for repair about 3 months ago.  This was the first time I'd tried it on
RTTY since I got it back.  Is it possible that it might have been
incorrectly aligned - if so, is it possible for me to correct that?

 

                Just wondering - as I said, the USER 2 button now sets
everything up correctly for me.
