Well, I left argo snaping shot overnight, centered at 137.7750. I first
calibrated it using the 153KHz BC carrier / 60KHz time stations as
reference. I don´t know if 153K is accurate enough but the freq difference
on argo between them was 0.05Hz.
The only thing I got was some traces at 137.7776Hz just before local dawn as
can be viwed at the attached pix. Argo on QRSS30 mode. Was a noisy night
down here.
Lets keep trying ...
