I use wireless Logitech K350 with the M510 mouse. Inexpensive, contoured, and easy typing even for a touch typist.
Widely available.  Easy installation.

I don’t especially like typing on it, but it’s not bad.

What is the manufacture and model of the keyboard?  My IBM keyboard finally bit 
the dust and I am in the market for a back light keyboard.  Would like to know 
what to avoid.

Is RF getting into a keyboard issue OK here, it is RFI in a way..

OK, Say you get RF into a USB keyboard. It just stops working and the only way 
to get it working again is a total re-boot.

I'm assuming the best option is ferrite beads on the cable.

Now question, where is the best placement of the beads. Keyboard end? Computer 
end?  BOTH?

I have two here, a small one where I could get one or two passes through the 
hole. ( it is a Radio Shack split thing )

and then a much larger one, also split,, but the hole is close to a inch ID. so 
I could do many turns.

What would be best to put where?
