Hi Gary,

It must be something else. The scroll rate in my picture is 10 minutes /=
=20
pixel! It is taken from my "DFCW-6000" window of my VLF grabber (2). The=
=20
display is locked to GPS, so OE5ODL must be at 8970.035 +-0.001 Hz.

Choose a FFT bin width of about 0.5 mHz or lower and assure your system=20
is locked to a MSK transmitter. Note that GBZ if OFF for some time=20
today, so GQD (22.1 kHz) might be a good choice in UK.

Good luck!

73, Stefan

Hi Gary, <br>

It must be something else. The scroll rate in my picture is 10 minutes

Since a few days OE5ODL is transmitting longer carriers arround 8970
Hz. Frequency stability is now reasonable fine to be monitored in 424
uHz. The distance to me is 380 km. Maybe others will receive him as
