Propagation conditions were not so good tonight, extremely wide impulse response.
CVC is preheating the oscillator now, very good!
...but the TX frequency is still about 340 Hz too high.
I was testing with several parameters during the first minutes, so many dropouts.
At 18:30 UTC this shitty wide clicking signal appeared on frequency. I think it's an over the horizon radar. Usually it stays on frequency for one or two hours. Obviously they did not like the CVC signal, so they left the frequency after 2 minutes or so.
At 19:00 UTC a carrier was on frequency for a minute. Perhaps someone made a mistake when tuning.

That OTH thing killed everything here too for a couple of minutes, but that was before I had got any sound. However the break can be seen in the log. Then my laptop played dead for a moment. The last hour was pretty good. The rest can be seen in the plot.

Hmmm, why were the last 20 seconds perfect? Is there something pestering me here locally that switched off just before 20 UTC, or was there QRM on or nearby 17640 kHz ???
