[TenTec] RASCAL interface and the Orion 565

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 

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 

Bob, K4TAX
