[UK-CONTEST] Wireless keyboard and mouse in the shack?

[F5vjc]

Anyone using a RF wireless keyboard and mouse in the shack and finding
it sensitive to RFI ?
I use an Infrared wireless keybd and mouse so no problem of course.
However the YL wants to buy a new Wireless desktop set for her PC and
they all seem to be RF wireless types now, (what freq?) Are these
things prone to RFI in a typical HF radio environment. Not QRO or
indoor antenna situation.

Any suggestions, make, type, known to be ok?

Thanks
