Your signal on the 20th detectable at Bielefeld via the
online receiver of Wolf Buescher DL4YHF, distance 303.75 km!

Just about exactly three wavelengths!

So, you are transmitting Stefan!

S/N is about 10.5dB in but I haven't optimised the blanker and
filter settings for use on vlf6 at that band, so, it probably
can be improved.

Is today's (21st) transmission on 2970.0 or 2970.005?

The signal at Bielefeld is still present today but remains on
2970.000.    It was not present on Friday or Thursday.
