There's only one f in Graf. Graf and Sheets have been regular
contributors to Radio-Electronics/Electronics Now/Poptronics for the
last several years. Some articles have resulted in quite entertaining
exchanges in the letters to the editor column. (Like the fairly high

engineer in one of the regional offices took great exception, RE February
and March 1986).
