Glad to begin a new season with a capture of SIW. Hope all of the 'regulars' return.

Yeah ... the slant line stuff goes 'way back' ... it's amazing how faint a trace will catch your 
eye. Then there was Laurence and his stair step on 137 kHz during his days in OK - also very eye 
catching. Laurence used to go on vacation, out of the country for weeks, and leave his Decca 
kilowatt chugging away the whole time! Guess it should be pointed out that he was renting a house at 
the time ;~) ... analagous to the saying about rental cars I guess.

Lots of great memories ... and every year brings new ones. Let the VLF/LF/MF good times roll!

Jay
