[TenTec] digital

[John Graves]

Steve,

Thanks for your offer.  I am using the Accessory cable and I built a 
quick and dirty interface  to drop down the speaker output from my 
laptop to feed the line input on the Jupiter. The sound input  on my 
laptop is happy with the line out from the Jupiter.  My Thinkpad, which 
crashed and burned, had line in and out so life was simple then. But the 
HP is not as cooperative.  Vox works on the HP  but I think I will be 
better served with PTT, so I am gathering parts for an interface that 
will pull DTR & RTS out the usb/serial line for PTT control.  Having 
that switched accessory jack is great!.It does make life easy.
