Dave:
I suspect the original pin configuration was conceived from the Engineering
point of view of implementation without realizing that a "standard" cable
purchased off the shelf was not constructed in the way needed. Then to
standardize the Orion's, Omni VII's and other radios AUX connector
functions, the change was necessary to use the standard cable.
Your point is well taken on the FSK matter with regard to levels. From my
thoughts, working PSK-31 and changing to AFSK, the levels are handled by the
computer software and I find no level change is required when changing
modes.
I see a strong recall of ideas and procedure as applied to old rigs, old
methods and old thinking on many topics, which today are totally incorrect
as applied to new modern radios, computers and such. Even with basic
thoughts and laws of Physics pertaining to antennas, feedlines, tuners,
baluns and etc., I see a large disparity of information.
As Will Rodgers said "it's not what people know that concerns me, it's what
they know that isn't correct that gives me concerns". Today in my work
today, as I encounter people and as we discuss a certain product, I find
that 9 out of 10 people have 100% incorrect information on the topic. It is
the "well I was told........bla, bla bla" Basically 20 years ago what
they were told was correct. Today it is 100% incorrect.
I too often find that I have to update my thinking and understanding on many
topics as related to ham radio matters. And too, more often than not, there
is something I've overlooked which puts me in the wrong thinking toward an
application. Yet, I still have to return to the fact ...the laws of Physics
haven't changed. Sometimes I forget that fact........largely chalked up to
" a senior moment" in my case. I view that 55 years in ham radio and
electronics and 70 years of age has its merits and drawbacks.

Thanks, Bob. The simple thing would have been to put the FSK on pin 5 of
the 8-pin connector when the Orion was designed. I know this sounds
simple, but I'm sure there was an engineering reason for the change . It
could be as simple as where a trace needed to be on a PC board. I changed
the cable rather than the transceiver because I didn't a non-standard rig
in case I sell it. (Can't imagine that.)
My reason for using the FSK is that I never have to worry about setting a
correct transmit audio level in RTTY. You're right about the guy o the
other end not knowing the difference. Modern rigs don't have the problem
of opposite sideband generation the old boat anchors did. PSK is still an
AFSK mode and the due diligence is required there when setting it up.
Guess I'm getting lazy in my old age
Also, thanks for all you do on the reflector. Always a good read, even
when I don't need the info currently. Ya' just never know

Dave:
Thanks for clarification of history on this point. I have the Omni VII and
the Eagle and both work correctly with the supplied cable, including the
FSK
mode for the Omni VII. I do have the Orion manuals here but no Orion radio
at present. Sorry if I disclosed incorrect information.
FYI - the Omni VII has a 5 pin AUX receptacle and the Eagle has a 8 pin
AUX
receptacle. The Tentec supplied 5 pin DIN connector will correctly plug
into either one correctly. Same for the Tentec 712 USB Soundcard interface
which has a 5 pin DIN connector.
With the Eagle, pin 5, pin 6, & pin 7 are for yet to be disclosed
applications.
I spend a reasonable amount of time operating the digital modes, all of
which are audio modes. In with this I work AFSK being generated via the
computer software. Most folks won't know the difference on either end. I
do the same for CW as well. In all cases, the radio is in the USB mode. I
have used the FSK mode, mostly to confirm certain applications and the
exact
frequency shift of the radio and firmware. The supplied cable and
completing the circuit on the correct connector on the dongle does work as
expected.

Rick,
You are 100% correct about the TenTec supplied cable for the FSK lead.
The
cable provided is the same as for the Omni VII. Unfortunately, when the
Orion II was designed (I have both Orion II & Omni VII) the FSK lead was
moved from pin 5 to pin 7 of the connector. This cost me a lot of time
because I blindly trusted the supplied cable in setting up FSK operation
of the Orion II.
A call to TenTec was answered with a statement that the cable is a
standard commercial product and that no 'correct' cable is available. So,
the answer was to replace the connector on the supplied cable with the
connector provided goodies bag that came with the Orion II and put the
leads on the correct pins. It's do-able (my 68 year old eyes and shaky
hands don't help) but is one of my very few rubs with TenTec. It's absurd
to me that an 'incorrect' cable is supplied with transceiver in this
price
class.

Jack is correct the Orion AUX jack has output that can be used for AFSK .
FSK on the other hand is more of an issue. If your friend is using the
Ten-Tec AUX cable for FSK I'm afraid he's out of luck. That cable does
not
bring out the FSK output. He'll have to build up a new cable or perhaps
purchase one from a 3rd party.
I'm using a US-Interface Navigator and it keys the rig with the PTT on
pin
3 and sends FSK on Pin 7 of the AUX jack. It has it's own DIN connector
and privides access to all pins on the Orion's AUX jack.
Also, if your friend has an "early" 565 he may need to add a 10k pull up
resistor between pin 7 of the AUX connector and pin 8 of the REMOTE jack.

That is very good Jack, the problem is that I am not the owner of the
Orion but
my friend W0TT is. I am trying to get him on RTTY.
Maybe you could send me a note off line on what cables you are talking
about?
We do want to be able to use FSK and NOT AFSK. And do CW without changing
cables. Joe K0BX Stop the insanity!
Please do not add me to any distribution lists (Joke, Stories or Junk)

a Rascal for RTTY with the Orion. one can use the cables that
came with Orion for RTTY direct to the computer. I have done exactly that
for
all the years I have had my Orions 565, mostly CW but MixW3 will do all
modes
just about with the above cable connections to computer.
