Dale,

	I have that covered, thanks.

	This is to supplement and be portable.

	I wish I could say that "a tutorial in power supply filter
design" would equip me but given my fragmented time I'd be lucky to
get through it with adequate comprehension and shocked if I remembered
enough of it to apply when I finally got to that point.

	I'll order a couple of them and see what RFI is generated and
what trial & error means of control are effective ... knowing that
y'all will be here to shake your heads & suggest a different method
when one fails.

:-)
