Hello Stefan, VLF,

Stefan's=A0recent experiment) writes:

Best results were obtained with the loop antenna oriented towards DK7FC (r=
ather=20

How do translate Paul's indications in SpecLab blanker parameters, I mean=

should I proceed in practice to set the blanker thresholdto the mean ampli=

Many thanks to all in advance for suggestions.
