[TenTec] RASCAL interface and the Orion 565

[Bob McGraw - K4TAX]

The Tentec supplied dongle has 4 cables/connectors.

They are:
Line Audio In = white - to pin 1 from computer sound card
Line Audio Out = yellow - to pin 4 to computer sound card
PTT = black to pin 3 - either a foot switch of manual switch.  Can be 
controlled from the RS-232 connector on the computer.
FSK = FSK to pin 2 - must toggle from high to low for mark / space

For true FSK {and not AFSK} a proper interface will be required to toggle 
pin 2 from high to low for proper mark-space operation.  The radio should be 
in FSK mode.  To activate PTT take pin 3 to ground.

The easiest way, use the Tentec 712 USB soundcard interface and the computer 
software of your choice.  No fuss, no mess, no external box to adjust.  The 
computer software handles all the levels and switching.  Only have to select 
AUX for the TX audio source.

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) 
without
my permission. ________________________________

Subject: Re: [TenTec] RASCAL interface and the Orion 565 One does not need 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.
