Mal,
 
counting the time ticks in your Argo captures, they appear to be exactly 3 minutes wide. Looking at the one from 12:23:55 UT, the intermittent carrier on 985 Hz had been present already at the beginning at 12:21. However the attached screenshot from the Heidelberg grabber indicates that Stefan's last dash started only at 12:23:12, and increased power at 12:24:30. Thus I would conclude that the Argo trace had not been caused by the DK7FC transmission.
 
Best 73,
Markus

Markus.
The freq is accurate but not atomic standard, time is also accurate.
You will have to decide if this trace is the correct transmission on 8.87 Kcs
The trace fades in/out.

Mal,
 
assuming your clock is accurately set in UK summertime, the first screenshot would have been at 11:00 UT when Stefan was transmitting full power. He was still off air until 12:23, then reappeared with reduced power during your second capture, and is up at full juice since 12:26 UT. 
 
Can you do a frequency check (eg. by injecting a known carrier, or GPS 1 pps pulses)? Positively receiving DK7FC in QRSS-3 resolution seems a bit far fetched, so reducing the bandwidth by going to a slower setting would certainly help.
 
Best 73,
