Hello all
It's been interesting following the discussion on the possibility of
crossing the Atlantic with amateur LF signals. Although the frequency is
much higher it may be relevant to mention that several stations in ZL are
getting consistent reception of the Galveston Texas NDB on 206 kHz. This is
reported as a 2kW beacon which presumably means there wouldn't be more than
500 watts or so in each sideband. Distance is about 12500 km and signals
peak just before Galveston sunrise. I don't have any data on GLS's antenna
but if it's anything like most NDB's would not be hugely efficient.
