OK0EPB on 7039,4 kHz

[ulx2]

Licensed (sorry for the off topic) but interesting "standard time-beacon" station, driven by pendulum situated in the vacuum chamber, was established in Czech Republic.

The pendulum with a rod made of fused quartz is oscillating with a frequency of 0,5 Hz. Position of the pendulum is controlling by the IR sensor, signals from which are driving the CW transmitter on the frequency of 7039,4 kHz with output power of 10 W. The maximum difference of time signal is held in the tolerance of 0,1 sec.

These signals are good audible here in Kiev at local evening time (e.g. 1600 - 1800 UTC), but often with a QRM from near frequencies. Narrow filter is necessary for a comfortable reception.

That's pretty cool.

Tried listening for it here @ 0020Z, but nothing at all.  Granted, 10W from there to here is going to be a very big challenge.
