Hi Steve,
The commander program I downloaded is the one written by Simon Brown 
specifically for the Yaesu ft817 radio.

As I said I could do nothing with it.

The program was written in 2003 and is build 739. I found help files that 
hadn't been written yet. It referred me to a Yahoo help forum on that 
program and radio.

The users guide was one of the files that was part of that program.

I opened it with Acrobat but couldn't get it to read past page one.

I tried page down to get it to go further down and control page down. 
Nothing!

For the moment I'm stymied.

I don't want to go into some other help forum. Most sighted people have no 
idea of how we use Windows based computers. So don't think I'll get much 
help in this direction.

I think I'm doing something wrong and missing one small vital element.

I can't see why  I can't run the program without a radio attached and at 
least poke around and look at menus etc.
