Thanks Alan.
I just uploaded sequential captures:
http://icas.to/argo/dcf39/
It started to show up about one hour before the sunrise.
My question is if DCF39's space freq exactly falls on 138,830.5Hz.
(Maybe my Spec Lab freq accuracy is to 0.05Hz or so.)
RX: DC RX (Fc 130kHz) directly fed into Spec Lab
Ant: Mini-Whip PA0RDT design up 17.5m (just 2.5m from bldg. top)
