Hi Wolf:

 

 

I am new with Spectrum Lab, I trying to decode  VLF signal ( MSK??)

 

My QTH locator is FF51XB and I am receiving signals in:

 

15.600  18.300 20.500 21.400 (strong NPM?) 22.700 streaming..

 

And 21.100  intermitent  tx

 

 

I need help for correct  Spectrum Lab setup to decode these signals..

 

Could you help me?

 

Thanks in advance.!
