Hello Stefan,

Attached is an Argo snip, the best of four captures overnight.
I'm using a 10 foot octagon loop, roughly based on a design
by VE7SL, into a DIY preamp, then a TS-440S.   Audio from
the receiver is processed with a DSP-59+ before being sent
to Argo in my old Win98 computer.  Frequency calibration is
off a bit, but it was the only signal present.
