All, Sorry about the incomplete post! I seem to always forget something. The resonator in the experiment mentioned in the other infinite Q blurb was loaded with a 10X3 toroid (6.3pf) and the receiver for the signal was a 12" sphere 1 meter away connected directly to a Tektronix TDS-820 digital scope (1megohm -at-20pf.) Paallel printer connected directly to scope. Richard Hull, TCBOR
