My first Ten-Tec product was a KR-40 keyer that I bought in 1971. Before that I used a bug but decided to take pity on those listening to my CW. I still have the keyer. It's now part of my satellite station. I know it's sacrilege to say this, but its smooth magnetic action gives the Begali paddle I use with my Orion II a good run for its money.. 73 Ray W2RS
