Well done G
I couldn't find that with Google. But I had forgotten the comedy
sketch the advertisement prompted.
I also found:-
""In 1974, Goodyear started the ball rolling by launching a
revolutionary new tyre with an endorsement by the former police
chief Sir Robert Mark in a style so wooden that it could only be
authentic. As he uttered the immortal words: 'I believe Goodyear
tyres make a major contribution to road safety', a cult ad was

I am convinced, but do it again.
On UK TV many years ago there was an advertisement for car
tyres, they didn't use an actor but an ex chief of police to say
"I am convinced that this is a contribution to road safety". The
one thing he didn't sound was convinced. I cant write with that
tone in my voice. :-)

Renato Romero / IK1QFK is running a 5 uHz FFT spectrogram on

The spectrogram is running since christmas evening 2016,

There are time markers in 1 week intervals.
I can see a dash, a trace right on the frequency. It appeared 2
days after i started transmitting, which is expected with an FFT
window time of nearly 3 days. The SNR was up to 12 dB during the
visual observation of incoming spectra.
Partly, the trace disappered during the transmission time
(destructive interference with QRN). However i can see a
resulting trace of a high average SNR and exact (!) frequency
stability relative to the other traces beeing present in the
I would tend to call it a serious detection of my signal.
Spectrogram experts, what's your opinion please?
The distance is quite exactly at 5 wavelength on that 101 km
It would be a first detection on ULF (0.3...3 kHz) between
DL - I !
