Hi Peter, I am not really in calibration at the moment and I have a limit
+/- 0.1Hz. But for what its worth I make the lines 137.7446 and 137.7528.
doubt whether Markus can hear(see) them at his location. I will try again
tomorrow when its a bit quieter, as they do make a useful marker at this
of the band.
Most of the time I only get one line and it is quite strong - audible at
On my receive system it is 137.7465kHz
On the other hand DFC39 is on 138.8305.
If I assume DFC is on 138.830kHz then I can apply a correction of -.5Hz to
make the line that I am receiving 137.747kHz
That W3EEE site is good is it not? During the period when the T/A was
exceptional Laurence was receiving most of the LF broadcast stations in EU
much stronger than usual.
