[TenTec] psk on orion

[Robert & Linda McGraw K4TAX]

I've run my Paragon's and my Omni VI+ on PSK-31 and other digital modes for 
years.  No interface required.  Sigs fed to and from the sound card via 1/8" 
phone to RCA shielded cables to the back of the radio.  My sound card does 
have Line In and Line Out level ports.  Those cards which only have MIC In 
and Speaker Out will require some basic external attenuation to really work 
well.  The resistive pads are basic L networks consisting of a 10K ohm 
resistor in series and a 1K ohm shunt leg.  I've put them in the 1/8" phone 
connector shell by using 1/8 watt axial lead resistors.  I use VOX control 
for the TX/RX switching.  Set the VOX hang time to minimum.  Never had a 
problem with the first bit of data being clipped.  Thanks to TT and fast 
switching radios.

Software is what ever you want to use.  At present, I use WSJT and MixW2 
quite successfully.  The ORION will be no different.  You will find it a 
fine radio for digital modes.

P.S. -  Be sure and turn off WINDOWS sounds just in case you leave the radio 
on and the VOX activated.  That way the world won't be blessed with the 
Windows ding dong etc. during boot up or shut down of the computer.
