Dear LF,
again, I would very much favour to stay with the
separation of transatlantic slots, ie. around 137.777 kHz for West-to-East and around 136.320 for East-to-West.
On LF, the problem is not only related to
a lack of dynamic range in the receiver backend. Here in Central
Europe, DCF39 keying sidebands spill out a lot of in-band energy, which can only
be effectively removed by blanking. These periodic cutouts then
modulate onto all in-band signals, creating a set of nasty 0.1 Hz
spaced sidelines around strong (but otherwise clean) amateur signals.
Kind regards,
Markus

In the past EU
QRSS beacons were transmitting in the 137.32 range. Did this changed? I think I
missed something.
