Here are the T and the W of the call sign, received with Spectran, together with what looks like a Loran line, at 135925 Hz. The S/N ratio was a bit more than 20 dB.
It looks like the timing of the QRSS keyer is not perfect, the second line of the W is shorter than the first, while the preceeding space is a bit too long. The QRG indicated on the display should be correct +-0.2 Hz
Here you have to add 135000 Hz to the displayed frequency.
The resolution
was not much high, so it takes a bit of imagination to see the fequency
shift
on the signal of Markus, DF6NM, but it can be seen.
