I picked this up at a recent fester. Looks to be some kind of NAV/COM remote tuning head. The back has an ARC-5 type connector for the tuning cable, but I'm not at all sure this critter is ARC-5 related. http://www.k3msb.com/misc/critter1.jpg http://www.k3msb.com/misc/critter2.jpg Apologies for the poor picture quality.... 73 Mark K3MSB
