Dirt Simple, Dirt Cheap

Digital Mode Interface

For the FT-817

Can it really be THIS simple?!?  Yes, I built a Digital

Interface for the FT-817 for almost no cost and

almost no effort!  As you can see from the photo,

the entire interface is built on the Xmit/Rcv switch.

I am using this with DigiPan II, but it should work

with virtually any soundcard software for PSK,

and for other digital modes also!

The Windows volume and recording levels are

used to set transmit and waterfall (receive) drive

levels, but a trimmer is also included to adjust the

transmit drive.  A standard Windows Mouse plug

fits the FT-817 data port, I used a cable cut from

an old mouse!   This interface does require you to

manually switch between transmit and receive,

but does not require ANY connection to the PC’s

USB or Serial Port!
