Hi Marcus,

yes http://df6nm.darc.de/mf/1476kHz.jpg should have=C2=A0auto-updated every=
 hour, except that unfortunately my PC stalled shortly after 4 UT.=20

The slow Argo is helpful. Comparing your 4:34 UT screenshot on OneDrive

we find that the swinger varied between +0.45 Hz (close to Ralph's frequenc=
y) and 0 Hz=C2=A0(nominal 1476 kHz). So it seems your display was around 0.=
5 Hz low at the end.=20

Unfortunately,=C2=A0this time Ralph's=C2=A0line did not appear near the upp=
er boundary of the swinger waveform. Do you want to=C2=A0you try again toni=
ght?

Best 73,
Markus (DF6NM)

 OK, may be the version I'm using have only 30/60/120 so I set it to 120 no=
rmal, 10 minute ticks.
=20
 Now 1:45 UTC ... the "sw inger" seems to vary across Ralph's line. The lin=
k to 1476.jpg on your site is updated from time to time? Or it is a manual =
sample?
=20
 At one of my screenshots there's a thin line at 22:52 UTC, the moment when=
 I switched to 60KHz to check freq cal. Then came back to 1476. Drift .1Hz =
for an not-ovenized lo seems ok for now. At least I figured that I can mact=
h any freq within +/- 1.5Hz.
=20
 May be I put another SDR-IQ using DL4YHF SpecLab ... and learn how to make=
 it locked to PPS :D
