Someone on the List was asking about BNC connector caps to cover up unused BNCs on the back of the K2... www.pasternack.com has them. $2.49 for PE6014, BNC male without lanyard chain; or $2.75 for PE6013, BNC male with lanyard chain. Digikey has the BNC male with chain for $6.08 each, number A24559-ND. These are the NON-shorting type, of course. -Andy
