When I was a kid as K1VKW back in the 60ies, I knew a couple of old National Hams, Russ W1EYZ and Don W1MXC (both SK now), if I remember correctly, Russ W1EYZ even had a National TV. National used to show off their latest stuff, NCX-3, NCX-5, HRO-500 and NCL-2000 at the local Quannapowitt Radio Club meetings in Wakefield MA. Steve K4JPN
