[TenTec] digital

[Ron Castro]

There are lots of 'interface boxes' on the market that can send audio 
between your computer and radio, although in my experience, they're not 
really needed.  The Orion II has audio inputs and outputs on the back panel 
that can tie directly to your computer sound card.  Make sure everything in 
the shack is grounded together to avoid RF feedback and ground loops.  For 
most modes, VOX is all you need for transmit/receive switching, although you 
can easily build a simple one-transistor interface to use a serial or 
parallel port to operate the PTT.

BTW, the Orion II is a spectacular radio for digital modes!
