John W1FV,
You and I are in very close agreement on heading because you are 73 degrees
from me and we are both saying approximately 75 degrees.
I can hear it on numerous web SDR receivers that are located in Europe
(England, etc.). Will be interesting to see what time of day we can no
longer hear it in the US versus when it is no longer heard in Europe.
Would be great to get a heading from someone in Europe.
