	It might.  It might not.

	May not need (or want) to be too big.  If it's travelling as rf
	hash (either conducted or radiated, a small one may be dandy.
	And big ones (I'll explain if asked...8)>>) can actually be less
	effective.

	Do simple things, and, if need be, keep trying more.  Look for
	a plug in mains noise suppressor, to go between the RR power
	pack and the mains.  If the TV and the rr are on the same circuit,
	try them on differnt ones.

	(Noise can travel thru the air (radiated) or thru the line
	(conducted).).  If its coming from the motor (probable) the
	advice of getting a cap on the motor is excellent.  Nearest to
	the source it can be filtered the better...  If still stuck, try
	some 'ferrites' that can clip over the wires.

	(By Coincidence, the man i learnt much EMI from learnt HIS
	while eningeering full scale trains for NS (Dutch Railways)).
