[Elecraft] Computer Keyboard and P3/SCGA

[Guy Olinger K2AV]

Hi Ed,

You can only mate a device with one receiver, as you suspected. That is so
that you can have two keyboards, mice in the same area, and have them
unambiguously belong to two different PC's. Being able to do otherwise
would kill that very common commercial usage, like close-by desks. That
ain't gonna change.

You can do that with USB mouse and USB keyboard with a USB KVM. Such as
from Best Buy, and many others, like

http://www.bestbuy.com/site/iogear-2-port-usb-kvm-switch-black/9694463.p?skuId=9694463&ref=212&loc=1&ksid=1b84b446-8c57-41a4-bb50-9d45338175e8&ksprof_id=8&ksaffcode=pg199014&ksdevice=c&lsft=ref:212,loc:2

Or you could try putting one wireless receiver in the USB KVM's common USB
port and running a USB cord to both the P3 and PC.
