Good signal from you Andy despite most of my antenna being on the =
ground!

Is there a beginners's guide to receiving? I looked at the ebNaut
Windows software page and it says:

"Spectrum Lab will filter the signal and apply strong sferic
blanking, and take care of timestamping and sample rate drift
correction. It will shift the received signal to baseband and output
a WAV file containing the I/Q channels which the decoder requires."
Does that mean there is a SpecLab USR file for this somewhere?
