[Elecraft] Computer Keyboard and P3/SCGA

[Charles R.Tropp]

Hi Ted,
Not all keyboards will work on the P3/SVGA. I would find out first if your proposed keyboard will work by seeing if the K appears on the bottom right of your screen when you have the data mode switched on. Even if it does, there is no guarantee that once you insert a switching mechanism in line  that it will continue to work. Apparently, the USB port on the P3 does not come with standard USB software which is why only "dumb" keyboards can work. 73, Charles N2SO

 Need help figuring out what may be an elementary problem with a computer and the P3/SVGA.
Here's my objective:  I would like to use a single wireless keyboard  / mouse both to operate the text functions on the P3/SVGA, and to enter data into the computer itself.  While operating I like to switch my monitor back and forth between the P3 and the Internet.  That's easy enough, with a DB15 switch box.  But I can't get the keyboard to mate simultaneously with two of the USB receivers (or whatever those little things are called) - one in the USB port of the P3, and the other in a USB port of the computer itself.
I am using a new Logitech keyboard and mouse, each of which came with a USB receiver.  Logitech has an app that allows up to six devices to communicate with a single receiver - e.g., keyboard, mouse, and whatever else through one receiver into the computer.  But when I mate the keyboard to the receiver plugged into the P3, it no longer communicates with the receiver in the computer, and vice versa.  In other words, I can mate multiple interface devices with one receiver, but I can't mate two receivers with one device.
That makes good sense.  If it were otherwise, it would likely cause no end of chaos in a multiple-computer environment.  But it leaves me with the question - is there a way to use one keyboard switched on the fly with the P3/SVGA and the computer itself?

Ted, KN1CBR
