I was looking at the grabber expecting to see the usual CW gang on 137  but
all I see is XEB and some big wide monster on top of him! Someone has a  big
signal here. What is it?

Hi Rick,
Is there a way you can  reverse the BFO offset on your receiver?
You must be listening in LSB  mode.

My Icom R75 always listens in USB mode.
Even with a somewhat  wider filter the station on 137
is inaudible when I am tuned to  137.7KHz.

For the correct frequency polarity with ARGO your  receiver
should be listening in CW - USB mode.
