Steve,
you might want to try to listen to the commercial transmitter DCF39 in
Magdeburg on 138.830 kHz (see http://www.qru.de/dcf39-beacon.html for
details). That transmitter has about 40 kW ERP, so that a good amateur
signal from Europe is between approximately 45 to 50 dB weaker than that
station. It has been heard at the East coasts of Canada and the US, and a
VK station has been able to detect the carrier by taking a long-term
averaging software.
DCF39 transmitts a steady carrier on 138.830 kHz, interrupted approximately
every 10 seconds by a 200 bd FSK signal with the space frequency on 139.170
kHz.
Good luck, best 73

... currently not QRV but preparing to be ready to transmit again
throughout the winter season with about 200 mW ERP, I am located 120 km
West of DCF39 ...
