[Lowfer] "A" for Andover

[Bill Ashlock]

All,

 

Since I've failed at designing a simple "WM" modulator for the new beacon I've decided to go for a really simple modulation format for my Andover beacon - at least for the time being. It's a square wave having a period of 8 minutes, with an amplitude of 0.1 Hz p-p, and it's located right at 185.30025. I've defined the lowest extremity to be a dot and the upper extremity to be a dash. Therefore the modulation comes out to be and "A"  .... OR is that an "N"?  :)

 

Oh, BTW my Ellsworth signal was surpassing the Andover signal a short while ago.

 

Bill
