Matt,

The Signal link USB is nice.  I have one and others on the list do as 
well.  cheapham.com has it for $89 plus shipping.     This price 
includes 1  radio specific cable to go from the unit to the radio.   In 
your case, it will plug into one of the mini din jacks on the front of 
your 480.    These are behind a little plastic cover that needs to be 
removed  just to the left of the  serial  db 9  connector.

  If you go the SL USB route (no matter where you get it) you should 
spend the extra $5 bucks or so and get the plugin  module for the 480. 
The SL USB can be configured for a lot of radios,  and comes with a 
bunch of little wire jumpers that need to    be plugged into a header 
inside the unit.     The optional, radio specific modules  plug into the 
header as a single piece, instead of 8  little jumpers.     When I got 
mine years ago, the modules weren't around, and I had to do the jumper 
thing.  Not the end of the world, but  spend the extra money and get the 
plug and play thing.

The unit does have knobs on the front for  audio in and out levels, as 
well as  vox delay.

Sorry you couldn't make any sense out  of the articles on 
hamradioandvision.com    I thought that  seeing what other people are 
doing might give you  pointers.

Before spending money on an interface, maybe just try some rx and see 
how it works.  To receive, all you need is a audio cable between  audio 
out of the radio, and line in on the pc's sound card.   I know you want 
to work all modes, but maybe just pick one for starters.  Download 
software for it and see if you can get the rx side to work.     The 
biggest problems for digital operation by the blind  are getting the 
signal tuned in, and getting your screen reader to  speak out something 
  that makes sense.    If you can't make the rx work to your 
satisfaction you might be wasting your money on an interface.


I think the MixW software John uses isn't free, but has a free trial 
period.  It never worked for me.  MMTTY for RTTY and Digipan for psk are 
both free.    In digipan, set the menu option  to "use arrows for seek" 
and the arrow keys on the keyboard will jump between signals on the band.

73, good luck, Steve KW3A
