It may be the delta in supply voltage on keydown slightly stimulating
one or more relay coils. The DC shift could move the contacts a tiny
bit. Or it might be an extremely small timing window, associated with
T/R switching, that puts a little glitch on a relay control line.
Either way it's nowhere near enough to change the state of a relay.
Nothing to worry about; in fact it might be therapeutic. But I'll
listen for it myself.
