Jeff admitted that he recently went to a gala with his wife. He was preoccupied with the problems he was having with his DC receiver. Suddenly DURING THE GALA he remembered having mis-identified two capacitors in the mixer. So he and his wife HAD TO GO HOME FROM THE GALA so that he could fix the problem. And apparently he is still alive, and married! Amazing! <\/b><\/div>\n<div><b><br \/><\/b><\/div>\n<div><b>Jeff wrote: <\/b><\/div>\n<div><b><br \/><\/b><\/div>\n<div><i><b>I have been a ham for just about 40 year and typically build kits lots of them most recent the QMX.

It has been so much fun and highly distractive to be apart of this Soldersmoke DCR family. And hope this continues!!
