Stefan and Jay,

 

Excellent work on this landmark achievement.

 

Fine work in experiment planning, design, and = control.

 

Hope Paul has a neon font for this in his VLF record list. =

 

Sub 9kHz E-W TA!

 

Thanks for providing a great day today for all longwave = enthusiasts.

H= i Jay, VLF,
