Previous QST Product Reviews described high end and portable dual lever keyer paddles, including some very expensive ones. The six dual lever paddles reviewed here are mostly mass produced and, with one exception, are more modestly priced. Two (Bencher and MFJ) use a long spring design, two are low profile designs from Kent and Vibroplex, and two are spring return keys from European manufacturers Begali and Scheunemann.rnPaired with electronic keyers, dual lever paddles use their two levers to control dits and dahs. They allow iambic operation, in which closing contacts with both levers simultaneously yields an alternating series of dits and dahs. With keyers featuring dit and dah insertion modes, holding the dit leverrnwhile tapping the dah lever inserts one dah into a series of dits (and vice-versa).
